This paper deals with the legacy to analytical chemistry in Brazil of one of the most influential chemists of the 20th century, Fritz Feigl, the centenary of whose birth occurred in 1991.


Probably written in 406-408, this dialogue between an unidentified bishop and Theodore, a deacon of the Church of Rome, has as its aim to point out Chrysostom as a model of what a true Christian bishop should be.


The relation between crush injuries of the chest and retinal haemorrhages and exudates has been recognized since the end of the igth century (Eales, I885).


In a recent issue of Psychiatric News, members of the DSM-5 Task Force reported on the dimensional measures being considered for DSM-5. These take 2 forms: severity scales for individual disorders, and "cross-cutting" measures that cut across disorders. For this brief piece, I will focus on the latter, the more interesting and controversial of the proposed dimensions.


Objective To investigate the p16,DAPK and ESRβ promoter methylation in the development of cervical cancer. Methods p16,DAPK and ESRβ promoter methylations were detected in cervical cancer tissues and serum by using methylation specific polymerase chain reaction( methylation-specific,PCR,MSP),and the clinical pathological correlation between them and cervical cancer was analyzed. Results In 100 cases of cervical carcinoma,p16,DAPK methylation rates were 80% and 35% respectively. Positive rate was significantly higher than that in the control group( normal or chronic inflammation of the cervix); Both p16 and DAPK gene methylation rate was 84%( 84 /100). In 30 cases serum of patients with cervical cancer, p16, DAPK methylation rates were 40%( 12 /30),20%( 6 /30)respectively. While the control group did not show methylation; Either p16 or DAPK of gene methylation rate was 46. 7%( 14 /30). But ESRβ promoter methylation was not detected in cervical cancer tissue or serum. With further analysis,there were close relationships between the p16 or DAPK gene methylation and cervical squamous cell carcinoma with statistical significance( P 0. 01). Conclusion p16 and DAPK gene promoter methylation in cervical cancer is closely related to the development of cervical squamous cell carcinoma. There is no any relationship between ESRβ promoter methylation and the occurrence and development of cervical cancer.


Fungal diseases of cotton plant ( Gossypium hirsutum L.) were studied during July, 2011 to June, 2012. Eleven cotton varieties were selected for the experiment. Alternaria alternata (Fr . ) Keissler, Aspergillus niger van Tiegh, Colletotrichum gossypii Sowthworth, Colletotrichum dematium (Pers.) Grove, Curvularia clavata Jain, Fusarium sp., Gleotrichum sp., Hyalopycnis sp., Pestalotiopsis guepinii (Desm.) Stay, and a sterile fungus were isolated from infected leaves of cotton varieties CB6 and CB11. Colletotrichum gossypii was isolated from both the varieties and C. dematium was exclusively isolated from CB6. Varieties CB6 and CB11 were more susceptible than other varieties. Cotton varieties CB1, CB2, and CB3 showed negligible infection on leaves and bolls. Colletotrichum gossypii and Hyalopycnis sp. are new record for Bangladesh. Moreover, association of C. dematium, Gleotrichum sp. , P. guepinii and Hyalopycnis sp. with cotton is being reported first time. The three fungi Colletotrichum. gossypii, C. dematium and Hyalopycnis sp. are described and illustrated in this account as new Deuteromycetous records for Bangladesh.

Machine Learning (ML) has become one of the highly participated courses at the undergraduate level in Computer Science. Open-source ML libraries make it easy for students to implement papers, share ideas, and conduct experiments on large scale datasets. With the emergence of public dataset portals (such as Kaggle, Amazon Datasets, and Google Datasets Search), the open-source community has produced many useful, high-quality libraries (such as Scikit-Learn, PyTorch, Keras, and Tensorflow among others). These open-source tools aim to make state-of-the-art ML algorithms and large-scale datasets accessible to all. While these ML libraries and datasets can benefit many undergraduate students in their pursuit of data-related careers, the task of choosing them for instructional purposes can be daunting for two reasons. First, all of these tools have advantages, drawbacks, and many overlapping issues. There is no single tool or dataset that covers all of the ML instructional needs. Second, due to the rapid advancements in the field, instructors often find a lack of comprehensive guidelines or standards on evaluating the instructional usability and real-world performance of open-source tools. How can these libraries and tools be integrated to aid the instructional activities of both classical machine learning as well as deep learning? This BOF will provide a platform for the discussion of the development of an open-source toolkit to support the teaching and learning of ML at the undergraduate level.


The objective of this study is to examine the impact of trade liberalization on Nepalese economy over the period 1990-2018. As per studies, trade liberalization increases the areas and size of foreign trade.  Nepal has introduced the economic and trade liberalization policy in mid-1980s and started to liberalize its trade and investment after 1990s. After the adoption of economic liberalization, the flow of foreign trade, economic growth of Nepal has been significantly increasing. The impact of trade liberalization on economy is measured in terms of economic growth, trade tax, industrial GDP and ratio of trade tax to total size of trade of Nepal by applying simple and multiple regression models. In Simple regression model, four equations show a positive correlation between INGDP and import, export, total trade, EOI inflation rate.


Informal Sector is the most important part of the workforce in India and other developing countries works. It has become a progressively more popular subject of study, not just in economics, but also in Social Work, Sociology and Anthropology. The term of "Informal Sector" was first coined by Keith Hart. There are many informal sectors in our country working for their own livelihood. The most frequently and regularly they have to work to earn their daily bread. After the implementation of Liberalisation, Privatization and Globalization there are several changes in the system and particularly with respect to the informal sectors belonging to Street Vendors. With this background, the researchers intended to study the socio-economic status and quality of life among the Street Vendors in Tiruchirappalli District, Tamil Nadu. There many Street Vendors in the heart city of Tiruchirappalli, hence the researchers used convenient sampling method to select 56 respondents for the present study and the study is descriptive in nature. The findings of the study are elaborated in the full paper.The government and non-governmental organization has to play a crucial role for the development of Street Vendors. Further few suggestions were also given to enhance their quality of work life.


Since the appearance of learning management systems, establishing a fair and precise mechanism to assess learning activities has been a challenging issue. Evaluation of group's work in blended learning environments which these systems are used can be a more complicated task due to implicit factors affecting result of final group's work, like degree of members' enthusiasm or their social relations (namely, communication or negotiation between group's members known as group's dynamics). The aim of this paper is to define comprehensive criteria for assessing group learning activities, considering standard learning progress taxonomy, during blended educational courses. We proposed a framework for assessment of online learning groups with respect to three major activities namely, forums, wikis and messaging. We measured correlation between performing these activities and enhancing learning skills with respect to Blooms taxonomy. We considered different parts of course exams' grades to evaluate performance of students in groups considering this taxonomy. Our promising results led us to believe that applying these criteria in blended educational courses may enhance the quality of collaborative learning activities and help student to perform better in learning groups through formative assessment of groups' work.

In the late nineteen-nineties, the European Union initiated an extensive research program which included also an animal experimental project with the acronym PERFORM-A. The aim of this project was to help clarify by means of an animal model whether high-frequency electromagnetic fields (EMF) can possibly have a carcinogenic or co-carcinogenic effect. Indications thereof had been provided, for example, by an Australian group of researchers, who had found a two-fold increased cancer risk in an EMF longterm study in transgenic mice (Repacholi et al. 1997). In addition to the European Commission, the PERFORM-A project was sponsored by the Swiss Federal Office of Education and Science, the GSM Association (GSMA), and the Mobile Manufacturers Forum (MMF). The Fraunhofer ITEM took on the scientific coordination of the overall project, supported by the University of Helsinki, which was responsible for the financial management.


Objective To evaluated the efficacy of dynamic hip screw(DHS),Gamma nail and proximal femoral nail anti-rotation(PFNA)for senile intertrochanteric fracture(ITF).Methods 162 patients with ITF were treated with DHS,Gamma nail and PFNA.The operative time,operation complications,bleeding volume and therapeutic efficacy were analyzed retrospectively among three groups.Results 162 cases were all followed up for 1~2 years.There were statistical difference in the mean operation time and intraoperative blood loss(P0.05).The postoperative blood loss within 3 days of the PFNA group was less than that in the DHS group.The overall incidence of DHS group was highest than the other groups within 18 months(P0.05);There were statistical difference in therapeutic effect(P0.05).Conclusions Compared with DHS and Gamma nail,the PFNA could be a reasonable choice for unstable and aged intertrochanteric fracture because of less operative time and blood loss,lower postoperative complications and more stable fixation.

Since the first discovery of quasicrystals in a man made Al‐Mn alloy about thirty years ago, people made great effort to investigate this kind of outstanding material. The materials scientists are constantly trying to produce stable quasicrystalline particles or even a complete single quasicrystalline specimen. On the other hand, the fracture behaviour of quasicrystals is started to be investigated because the coupling effect between phonon and phason fields can rebuild the conventional fracture criteria. This work develops a numerical tool for simulating in‐plane problems of 1D QC and extends the fracture quantities i.e. stress intensity factors (SIF) and strain energy release rate to phason fields. Finally, numerical results are given to reveal what difference the phason field can bring into conventional fracture quantities. (© 2015 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)


Book review: A Most Dangerous Book: Tacitus' 'Germania' from the Roman Empire to the Third Reich. By Christopher B. Krebs. New York: W.W. Norton and Company. 2011. 303. It is a rare experience for historians to shock other people simply by doing their work. I was on an aeroplane holding a book in my hands, when an elderly English lady on my left asked me with unveiled suspicion and in a rather loud voice, 'What on earth are you reading?' In my puzzlement, I showed her the cover, and then I realized. There was a red Swastika on the front, and it was next to the title 'A Most Dangerous Book'. It took me quite a while to convince the lady that the title referred to another book and that I was not a closet Nazi. In the end, she even seemed to believe me that, for an academic book at least, it was not a boring read at all.

A Most Dangerous Book deals with a short and sober ethnographic description written almost two thousand years ago by the Roman historian Cornelius Tacitus. The Germania, as it became to be known in modern times, did not seem dangerous to anybody for centuries, and neither does it today. Yet, Nazis in general and Himmler in particular liked it a lot, and this is what earned it a place in an (imaginary) top-hundred list of 'most dangerous …


regime and have led to changes in forest structural characteristics (Agee 1993, Sensenig 2002). High-severity, stand-replacing fires also have been known in this region, where complex topography and fire behavior typically resulted in a patchy distribution of canopy openings, intact stands, and scattered surviving trees (Wills and Stuart 1994, Alexander et al. 2006). The prognosis of forest recovery after high-severity forest fire is uncertain. A history of regeneration failures after fires and logging raised concerns over the long-term sustainability of conifer forests in the region (Hobbs et al. 1992). Large brushfields dominated extensive areas in southwest Oregon in the mid-20th century and may have resulted from fires set by early settlers, ranchers, and miners (Hayes 1959). Limited conifer regeneration over long periods (10–50 years) fostered concerns that such areas would remain unforested indefinitely (Gratkowski 1961). Additional regeneration failures occurred after clearcut harvesting, and attempts to improve the regeneration environment through shelterwood cutting had mixed results (Stein 1986). Given this history of uncertainty, questions arose as to whether conifers would regenerate after the high-severity forest fires of recent times. Fears emerged that the brushfields common to the Klamath-Siskiyous highland in the early 1900s (Hayes 1959, Gratowski 1961) would become a dominate feature of the forests of the 21st century as well (Sessions et al. 2004). Of particular concern was the competitive advantage of broad-leaved shrubs and hardwoods that may result after the removal of the conifer overstory by fire. Hardwoods, particularly tanoak (Lithocarpus densiflora), madrone (Arbutus menziesii), and oaks (Quercus spp.), resprout vigorously after fire (Brown and Smith 2000). The rapid growth of seed-bank species such as Ceanothus and their association with nitrogen-fixing bacteria can lead to extensive shrub cover in early successional communities in the region (Hanson and Stuart 2005). Without active reforestation, conifers may have little or no window for regeneration amid the rapidly growing shrubs and hardwoods (Hobbs et al. 1992, Sessions et al. 2004). Along with competition for moisture and growing space, high levels of seed predation and high surface soil temperatures result in high mortality rates within the 1st year (Minore and Laacke [1992] and references therein). Extensive research has documented the advantage of planting conifers and controlling shrubs to increase tree density and growth over the early years of stand development (Hobbs et al. 1992, Zhang et al. 2006). Today, many postfire action plans regard treeplanting and vegetation control as a relatively straightforward and effective solution to the problem of forest renewal (Lindenmayer 2006). Little is known about how burned areas will recover on their own, how they might differ from stands managed after fire, or how these differences relate to the rate of forest recovery after fire over the short term (1–2 years) or longer (1–2 decades) time frames. The lack of information concerning ecosystem recovery, specifically natural conifer regeneration after wildfires, has allowed speculation on complex ecological processes. For example, in a recent 2-year study of conifer survival with and without salvage logging in southwest Oregon, Donato et al. (2006) concluded that postfire management activities 2 years after a fire killed most natural tree regeneration and may be counterproductive to forest recovery. This conclusion contradicted recommendations of a recent policy analysis for southwest Oregon, which argued that burned areas can develop into unproductive shrub fields that persist for "decades, perhaps centuries" and that postfire salvage logging and treeplanting would speed the recovery of complex conifer forests and provide revenue from timber extraction (Sessions et al. 2004). We report here on the abundance of natural regenerating conifers occupying sites 9–19 years after stand-replacing wildfires in northern California and southwest Oregon. Our findings redefine concepts of the role and reliability of natural regeneration in high fire frequency systems in the context of ecosystem management (Christensen et al. 1996). Additionally, they highlight the role of temporal and spatial variation as an inherent feature of forest development. Forest managers relying on natural regeneration should feel increased confidence and need to develop plans that can accommodate high levels of variation and accept the prolonged time line of the regeneration process.


Ultrasonic imaging has not been used for primary visualization of brain parenchyma in fetuses or neonates, although it is applied routinely for evaluation of ventricles (and other fluid collections) and for the detection of intracranial hemorrhage and neoplasms. We have begun investigating cerebal parenchymal appearance directly with a large aperture, dynamically focused array immaging system having improved signal to noise ratio and regional magnification features.We find that bone is not an absolute deterant to imaging, through 6 weeks post term, although some refraction effects are noted when molded heads (i.e. surviving small premature infants) are viewed in coronal planes through a water path. Convolutional markings in the cengulate region in midsagittal views in fetuses and in newborn infants show a progression in complexity between 28 and 32 weeks and after 37 weeks in accord with the necropsy correclation with gestational age. The definition of markings and primary reflectivity increases progressively in the third trimester. An Increased reflectivity and damped anterior cerebral branch artery pulsations occur after asphyxial episodes and are interpreted as an extracellular fluid shift. Decreased echodensity and splaying of markings are typical of edema. Thickened sulci herald aophy in subjects beyond 4 months of age.


In order to clarify the mechanism of the hemostatic plug formation from the morphologic standpoint, scanning electron microscope observation was made on the inner surface of the rabbit carotid arteries 1, 5, 15, 30 and 45sec after stabbing with a needle. The arteries were first fixed in situ by an infusion of glutaraldehyde and then, after being excised, by immersion in glutaraldehyde and in osmium tetroxide. The critical point-dried and gold-palladium covered specimens were examined in a field emission type scanning electron microscope.Stabbing made a hole, about 0.25mm in diameter, in the arterial wall, and the ruptured endothelial cell shrank and retracted. Thus the subendothelial collagen fibers were exposed and hung on the wall of the holes. Some of the fibers were single and wavy and others were compactly packed in bundles, forming a network.The first step of the hemostatic process was adhesion of discoid platelets which were attached, with their bodies or frequently with their pseudopods, to the collagen fibers especially at the marginal and hanging part.On the adhered platelets other free platelets subsequently came to be attached. A thin layer of the platelet aggregates thus formed grew thicker, though somewhat distorted by the blood stream. At this second stage some erythrocytes were found hanging from the collagen fibers or undergoing collapse, suggesting its contribution to platelet aggregation by releasing ADP through hemolysis. The aggregate layer became so thick that it almost obliterated the hole and rose on the arterial lumen 45 sec after the stabbing.Aspirin which has been shown to affect platelet aggregation in the second phase was demonstrated to lower the rate of aggregate formation to half to one-third.


The first "scientific jouney" to the New world has produced a entirety of reports that was recorded in several respects. One of them is the "Relation abrege", a text of its protagonists on the stage that has been done navigating the Amazon River. We aim to produce a reflection on the production conditions of the observation that generated the "summary statement', as well as on the reception that such writing deserved in Europe.

The authors present an observational and theoretical review of the winds of cataclysmic variables (CVs). Specifically, they consider the related problems of the geometry and mass-loss rate of the winds of CVs, their ionization state and variability, and the results from studies of eclipsing CVs. Finally, they consider the properties of accretion disk wind models. Some of these models predict substantial angular momentum loss, which could affect both disk structure and binary evolution.


The effect of cations and their hydrolysed products on kaolin and silica slurries have been widely studied in various literature. However, the effect of cations and their hydrolysed products on alumina and silica sheets in kaolin particles have never been isolated. The addition of Ca2+ cations into alumina slurries caused increments in alumina particle positive charges. The addition of Ca2+ cations into silica and kaolin slurries caused reductions in silica and kaolin particle zeta potential magnitudes. Ca2+ addition also caused significant yield stress increments from pH > around 10 within alumina slurries and pH > around 8 within silica and kaolin slurries. With and without Ca2+, the zeta potential-pH and yield stress-pH behaviours of kaolin slurries were similar to silica slurries than to alumina slurries. This suggests that silica sheets, compared to alumina sheets, could affect kaolin particle behaviours to greater extents.


Purpose – The results of a study of friction welding of ductile cast iron using stainless steel interlayer are presented. Based on the microstructure evolution at the region close to the ductile cast iron‐stainless steel interface, the phenomena accompanying the process of joining were evaluated. Therefore, the purpose of this paper is to take a closer look into metallurgical phenomena accompanying the friction welding of ductile cast iron.Design/methodology/approach – In this paper, ductile cast iron and austenitic‐stainless steel are welded using the friction welding method. The tensile strength of the joints was determined using a conventional tensile test machine. Moreover, the hardness across the interface ductile cast iron‐stainless steel interface was measured on a metallographic specimen. The microstructure of the joints was examined using light metallography as well as electron microscopy. In this case, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were applied. En...


The invention relates to a method to evaluate pitting corrosion resistance performance. Wherein, introducing the repassivation temperature as a parameter to evaluate the performance, using standard three-electrode system in electrochemistry and constant externally-applied potential corrosion current density-temperature periodic scan method to measure repassivation and critical pitting corrosion temperature of material. This parameter can actual and objective reflect the pitting corrosion resistance and repassivation performance of material, the temperature periodic scan method can measure the opposite temperature rapidly and directly and accurately.


Alloys from ZnO and ZnS have been synthesized by radio-frequency magnetron sputtering over the entire alloying range. The ZnO1−xSx films are crystalline for all compositions. The optical absorption edge of these alloys decreases rapidly with small amount of added sulfur (x ∼ 0.02) and continues to red shift to a minimum of 2.6 eV at x = 0.45. At higher sulfur concentrations (x > 0.45), the absorption edge shows a continuous blue shift. The strong reduction in the band gap for O-rich alloys is the result of the upward shift of the valence-band edge with x as observed by x-ray photoelectron spectroscopy. As a result, the room temperature bandgap of ZnO1−xSx alloys can be tuned from 3.7 eV to 2.6 eV. The observed large bowing in the composition dependence of the energy bandgap arises from the anticrossing interactions between (1) the valence-band of ZnO and the localized sulfur level at 0.30 eV above the ZnO valence-band maximum for O-rich alloys and (2) the conduction-band of ZnS and the localized oxygen le...


CdSe nanocrystals were synthesized by non-aqueous solution method in mono-solvent system of hexadecylamin(HDA) and di-n-octyl phthalate(DOP) respectively.Different shape of CdSe nanocrystals such as hexagonal quantum dots,multi-pod and nanorods were obtained by adjusting the addition rate of monomers and temperature.The as-prepared CdSe nanocrystals were characterized by TEM.It was found that the supersaturation of monomers could dramatically influence the shape of CdSe nanocrystals both in HDA and DOP.The increase of supersaturation could lead to the preferential growth in the direction of(001-) of wurtzite structure.To some extent the shape control strategy in HDA and DOP is different.High-quality CdSe nanocrystals can not be obtained at 200 ℃ or below.


Suffering remains a great mystery of nature which human mind is not capable to understand. Any progress, any technique or medical equipment or even the most advanced machines are not able to eliminate pain or disaster from the world. They accompany human beings from the very beginning and they will still be with us until the end. Some people are afflicted by pain more often than the others. In Faustyna Kowalska's life, who belonged to the most well-known contemporary world saints, existed the mystery of pain which changed her life and manifested the presence of Christ. This modest woman was chosen to promote God's mercy to mankind. In the life of suffering nun essential role played theological virtues – faith, hope and love. In connection with the saint sacraments which strengthen her in her suffering let her enjoy the peace of her soul and fruit of trust in God. Diary of nun Faustyna is a heartbreaking record of spiritual flights and darkness which is a certificate of tough and indomitable faith. Above all, it is a proof of definite belief in the greatest God's attribute – his incomprehensible and infinite mercy.


Recent progress on the (g - 2)μ prediction is presented. In the SM, the Higgs-boson mass dependent contributions have been evaluated exactly up to the two-loop level and consistently combined with leading three-loop effects. Thus, the currently most accurate value including a detailed error analysis for the SM electroweak contributions has been obtained. The SUSY two-loop corrections from fermion/sfermion-loop insertions have been computed; they are generally large and logarithmically enhanced for heavy squarks.


Fully and partially pendant acetal group substituted polyvinylphenols were synthesized by the methods of free radical polymerization and chemical modification on polyvinylphenol, respectively. The glass transition temperature (Tg) of the partially acetal-substituted polyvinylphenols is in the range of 135 degrees to approximately 148 degrees Celsius, which is enough to overcome the thermal treatments for resist processing. The partially acetal- substituted polyvinylphenols are promising materials for chemically amplified negative tone deep UV photoresist.


Energetic particle environments are an important factor for the viability of life on exoplanets surrounding flare stars. In the heliosphere, large gradual solar energetic (E > 10 MeV) particle (SEP) events are produced by shocks from fast coronal mass ejections (CMEs). Extensive observations of solar X-ray flares, CMEs, and SEP events can provide guidance for flare star models of stellar energetic particle (StEP) events, for which stellar flares, but only rarely the associated CMEs, are observed. Comparing an extensive list of peak fluxes, timescales, and peak temperatures of 585 ≥ M3.0 solar X-ray flares with the occurrence of associated SEP events of peak flux Ip > 1.4 proton flux units, enhanced with proxy decametric–hectometric type II radio bursts, we determine guidelines for StEP event outcomes, given only stellar X-ray flare inputs. Longer timescales and lower peak temperatures of X-ray flares with a given peak X-ray flux Fp are more favorable for occurrence of associated SEP/StEP events, which, however, are only a minority of all solar flare outcomes. Most solar flares do not result in SEP events, invalidating scaling laws between stellar flares, CMEs, and StEP events. We discuss recent observations and models of the flare–CME relationship and suggest that StEP intensities Ip may often be overestimated.

This study aimed to seek contributions to the development of investigative activities that use the history of mathematics as a trigger of the teaching- learning process that a study of the Theorem of Thales can bring to a class of 9th graders. Here the authors used the studies based on the work of Iran Abreu Mendes and Marger Viana da Conceicao Ventura and other authors about the teaching- learning process on the pedagogical potential of the History of Mathematics. The research drafted 11 investigative activities that are justified by the importance of such activities as a methodology for teaching mathematics. Twenty- nine 9th grader students in a public middle school in Ouro Preto, Minas Gerais participated in this study. The research field was conducted in 11 meetings, totaling 18 lessons of 50 minutes each. In order to assess the basic knowledge related to the history of mathematics and geometry, the researchers also collected data from responses to a questionnaire. Data from observations collected from the field notebook and the written records of the participants. The participants' cell phone was used during the meetings as a tool for recording conversa tions. The purpose of these actions was to collect and analyze data related to the research question: What contributions can come from the development of investigative activities that use the history of mathematics in the teaching- learning of the Tales Theorem? In addition to learning the Thales Theorem, other aspects were observed in this research such as an overall change in the view of the participants on mathematics classes, and modification of their behavior such as reduced verbal and physical aggression, change in disinterest and lack of commitment as well as increased self- confidence. Gradually, the observers noticed increased positive attitudes and a transformation making it possible to promote an environment conducive to the interaction, cooperation and respect among participants, which is necessary in the teaching -learning process.

Effect of iron and chelator on the growth and siderophore production in the ten newly Frankia strains isolated from the root nodules of Hippophae salicifolia D. Don and the two reference strains were studied. Growth of the strains was greatly affected when grown in the iron and EDTA deprived conditions. All the strains were capable of producing both the hydroxamate and catecholate type siderophore that was detected using the Csaky and Arnow assays. Production of siderophore was enhanced in the EDTA replenish condition in contrast to the iron supplemented medium suggesting that EDTA reduces the availability of other free metals and hence creates the stress condition for which the secretion of siderophore is enhanced.

[Objective] To study the dynamic changes of the [Ca2+]i in hippocampus neurons of rats with focal cerebral ischemia and the effect of "XNKQ" acupuncture to explore the the rapeutic action of early intervention with "XNKQ" acupuncture.[Methods] MCAO was established in rats.They were treated with "XNKQ" acupuncture method.At different time point the dynamic changes of the [Ca2+]i in hippocampus CA1 neurons were examined with confocal laser scanning microscope.[Results] Compared with the control group,the two neuron [Ca2+]i of hippocampus CA1 regions of model group began to increase after ischemia for 1h,and sustained to elevate until 24 h(P0.05),while the sham operated group had no difference(P0.05).At the same time point,there was no difference of [Ca2+]i between non-acupoint group and model group(P0.05),while the "XNKQ" acupuncture group was significantly lower than that of the model group(P0.05,P0.01).[Conclusion] The [Ca2+]i in hippocampus CA1 neuron of rats is increased persistently during acute focal cerebralis chemia,causing the calcium overloading in cells.The study results also suggest that "XNKQ" acupuncture method can regulate the[Ca2+]i in the focal cerebral is chemia,and the earlier the better.All of these offer the evidence to use acupuncture at early time in clinic.


Haptic force feedback systems are unique in their ability to dynamically render physical representations. Although haptic devices have shown promise for supporting learning, prior work mainly describes results of haptic-supported learning without identifying underlying learning mechanisms. To this end, we designed a haptic-supported learning environment and analyzed four students who used it to make connections between two different mathematical representations of sine and cosine: the unit circle, and their graph on the Cartesian plane. We highlight moments where students made connections between the representations, and identify how the haptic feedback supported these moments of insight. We use this evidence in support of a proposed theoretical and design framework for educational haptics. This framework captures four types of haptic representations, and focuses on one -- the haptic bridge -- that effectively scaffolds sense-making with multiple representations.


The contact between the single bristle and the rotor shaft surface was modeled using the linear cantilever beam model and the augment Lagrange contact theory. The bristle-rotor contact force and flow-induced uniformly distributed bristle load in rotor cross section were considered in the present model. The influence of the bristle lay angle,interference and flow-induced uniformly distributed load in rotor cross section on the bristle-rotor contact force was numerically explored. The results show that the effect of the flow-induced uniformly distributed bristle load in rotor cross section on the rotor-bristle contact force is more significant than that of the bristle lay angle and the interference in the range of the studied parameters. The bristle-rotor contact force has a minimum value when the bristle lay angle equals 35°. In addition,the contact force decreases with the angle when the angle is below 35°. However,when the bristle lay angle varies beyond 35°,the contact force increases with the angle because of the effect of the flow-induced uniformly distributed load on the bristle in the rotor cross section.


The authors have shown in their previous studies that applications of x-ray scattering techniques in a transmission geometry open an avenue for in situ structural investigation of silicon/solution, in general, semiconductor/solution interfaces. In these studies, the surface morphological evolution was deduced from x-ray reflectivity measurements and the pore-pore pair-distribution function was obtained from diffuse scattering measurements. The combination of these two techniques provided a complete phenomenological description of the pore formation and growth based on the most fundamental Langevin equation of interface-evolution phenomena, known as Edward-Wilkinson model. In essence, the high-current-density condition, where the surface etching occurs via surface oxidation of silicon and dissolution of the surface oxide, inhibits short-wave length fluctuations and the low-current-density condition, where the surface etching occurs via direct dissolution of H{sub 2}SiF{sub 6} formed at the interface, amplifies fluctuations with length scales of space-charge width. These two conditions are found to be consistent with the sign inversion of coefficient for the curvature dependent term of the Langevin equation. In this study extending the previous studies, the authors will show that the luminescence and the two conditions under which the porous silicon (PS) produced are directly related, based on x-ray and photoluminescence (PL) measurements.


Las1 is an essential endoribonuclease that is well-conserved across eukaryotes and a newly established member of the HEPN (higher eukaryotes and prokaryotes nucleotide-binding) nuclease family. HEPN nucleases participate in diverse RNA cleavage pathways and share a short HEPN nuclease motif important for RNA cleavage. While most HEPN nucleases participate in stress activated RNA cleavage pathways, Las1 plays a fundamental role in processing the pre-ribosomal RNA. Underscoring the significance of Las1 function, mutations to the LAS1L gene have been associated with neurological dysfunction. Two juxtaposed Las1 HEPN nuclease motifs create its composite nuclease active site, however the roles of the individual HEPN residues are poorly defined. Here we show through a combination of in vivo and in vitro studies that both Las1 HEPN nuclease motifs are required for nuclease activity and fidelity. Through in-depth sequence analysis and systematic mutagenesis, we define the consensus Las1 HEPN nuclease motif and uncover its canonical and specialized elements. Using reconstituted Las1 HEPN-HEPN'chimeras, we define the molecular requirements for RNA cleavage. Intriguingly, both copies of the Las1 HEPN motif are necessary for nuclease specificity revealing that both HEPN motifs participate in coordinating the RNA within the active site. Taken together, our work reveals critical information about HEPN nuclease function and establishes that HEPN nucleases can be re-wired to cleave alternative RNA substrates.


Data‐driven stories comprise of visualizations and a textual narrative. The two representations coexist and complement each other. Although existing research has explored the design strategies and structure of such stories, it remains an open research question how the two representations play together on a detailed level and how they are linked with each other. In this paper, we aim at understanding the fine‐grained interplay of text and visualizations in geographic data‐driven stories. We focus on geographic content as it often includes complex spatiotemporal data presented as versatile visualizations and rich textual descriptions. We conduct a qualitative empirical study on 22 stories collected from a variety of news media outlets; 10 of the stories report the COVID‐19 pandemic, the others cover diverse topics. We investigate the role of every sentence and visualization within the narrative to reveal how they reference each other and interact. Moreover, we explore the positioning and sequence of various parts of the narrative to find patterns that further consolidate the stories. Drawing from the findings, we discuss study implications with respect to best practices and possibilities to automate the report generation.


Objective To investigate the effect of TGF β 1 and EGF on the proliferation of cultured human prostatic epithelial cells. Methods The primary culture was prepared by collagenase digestion of minced prostatic tissue obtained from prostatectomies of 8 benign prostatic hyperplasia(BPH) patients (aged 53 to 70) and 5 organ donors (aged 23 to 36). Cells were cultured in serum free prostatic epithelial cell growth media and identified by immunocytochemical method. The cells were passaged and cultured in media without bovine pituitary extract (BPE) and then, EGF and TGF β 1 with different concentration were added into the culture either alone or in combination according to the experimental protocol. The cell proliferation was assessed by counting the cell number (BrdU) and ELISA. Results Cultured cells showed typical morphological features of epithelium and stained positive for PSA and Pan Keratin. After 5 7 passages cells went senescence. BPE and EGF enhanced whereas TGF β 1 inhibited the cell proliferation and the inhibition was reversed by increasing the concentrations of EGF. The effect of both TGF β 1 and EGF displayed concentration dependent manner. Conclusions Cell proliferation of the cultured human prostatic epithelial cells could be modulated by TGF β 1 and EGF. These results indicated that TGF β 1 and EGF, as the negative and positive growth factors might play an important role in the pathogenesis of BPH.


Summary Potential employers of future health informatics graduates were surveyed as to their view of what informatics knowledge and skills were required to contribute to their organizations. 84 respondents clearly indicated that the most important of six areas of knowledge and skills was communications skills, followed by informatics knowledge, management knowledge, informa tics skills, analytic skills, and health services knowledge. The survey also revealed that the ranking of the six areas was the same for differing organizations and differing respondent groupings.


Land-use change and forestry is the major category featuring carbon sequestration in the annual US Greenhouse Gas Inventory, required by the United Nations Framework Convention on Climate Change. We describe the National Greenhouse Gas Inventory and present the sources of our data and methods and the most recent results. Forests and forest products in the United States sequestered more than -790 million metric tn of CO2 equivalent in 2008, on 253 million ha of forestland. This estimate represents a net increase in carbon, including effects of growth, harvests, or other disturbances of forest ecosystems, as well as carbon stored in harvested wood products. Both area and carbon density of these forestlands have increased since 1990, the first year estimates are required. Currently, 89% of net annual sequestration is in the forest ecosystem, and the balance is net carbon addition to harvested wood products.


Each year in preparation of annual financial statements must be evaluated the entity's assets to be presented, so that these assets to be recorded in the financial statements at fair value need regular revaluation. Revaluations should be made with sufficient regularity so that the accounting value to does not differ substantially from that which would be determined using fair value at balance sheet date, so is guaranteed the true and fair view of the financial statements. The study contains an analysis of the 25 listed entities on the Bucharest Stock Exchange (BSE) tier I. of the revaluation policy, in relation with debt ratio of the entity, size of the entity, amount of tangible assets (tangible assets share in total assets) and in relation with the seniority (age) of tangible assets.

Results of quantitative X-ray photoelectron spectroscopic analysis are influenced by thin overlayers. Therefore, the reduced thickness of these layers has to be determined to allow a compensation to be made for this influence. An applicable method is based on the variation of the take-off angle. In this paper the angular dependence of the photoelectron count rate caused by surface roughness is discussed. It is created mainly by X-ray shading. As a consequence of these considerations the ultimate roughness depth can be given up to where the angular response of the count rate is not affected by X-ray shading and thus the method of the variable take-off angle can be applied.


This paper presents results from a coupled thermal and power loss analysis of an open-slot permanent magnet (PM) generator. The research focus has been placed on the winding design providing minimum power loss at ac operation together with low-cost manufacture. The analysed PM generator is intended to operate at fixed-speed allowing for the winding design to be finely tuned for the single operating point. Such a design approach has not been widely reported in the literature, and the existing body of work is focused largely on the variable-speed applications, where the winding design is a compromise between the low- and high-speed operating points, for a given torque speed envelope. The ac winding power loss has been analysed for several winding variants with different conductor dimensions accounting for the winding operating temperature. The calculated results suggest that in the analysed PM generator, lower winding slot fill factor is preferable as compared with the more common approach, where the highest manufacturable winding slot fill factor is usually considered. The power loss predictions have been supplemented with thermal analysis of the complete generator assembly for the winding variants considered illustrating the importance and influence of the appropriate winding design on the power output capability of the fixed-speed PM generator. The most promising winding design for the minimum power loss at the rated operating point has been down selected for prototyping. Theoretical findings from the analysis have been compared against experimental data from hardware tests on a stator winding section showing close agreement.

Data has been presented to show the relationship between load, inflation pressure and speed on the power absorbed by both bias and radial truck tyres, and the effect of this absorbed power on the tyres' running temperatures at high speed. The vital importance of using the correct pressure to obtain maximum tyre life and fuel economy has been demonstrated. Increasing fuel costs will accelerate the change from bias to steel radial, which now has around 50 per cent of the truck market. The steel radial is still the best tyre with an accelerating change from tubed to tubeless type. Wide steel radial singles replacing duals on trailer axles is becoming more common, particularly for applications where the improved vehicle stability from lowering the centre of gravity is a real advantage. However, correct tyre selection, coupled with the correct load and inflation, will remain the major factor in getting the best from both the tyres and the rig (a).


The Object Constraint Language (OCL) is a textual, declarative language used as part of the UML standard for specifying constraints and queries on models. As such, generating code from OCL expressions is part of an end-to-end model-driven development process. Certainly, this is the case for database-centric application development, where integrity constraints and queries can be naturally specified using OCL. Not surprisingly, there have already been several attempts to map OCL into SQL. In this case study, we invite participants to implement, using their own model-transformation methods, one of these mappings, called OCL2PSQL. We propose this case study as a showcase for different methods to prove their readiness for coping with moderately complex model transformations, by showing the usability, conciseness, and ease of understanding of their solutions when implementing a non-trivial subset of OCL2PSQL.


MEASUR's Semantic Analysis is a method for requirements analysis and representation. Semantic Analysis appears to have a number of benefits to information systems development. Among its main strengths is that it produces stable software design that is easy to be expended to accommodate future changes. However, it is not widely used, mainly because of its complexity. It is hard for analysts to follow the steps which sometimes are not clear and may lead two analysts to produce a significantly different ontology chart diagram for the same problem statement. There are not silver bullets for dealing with this problem but a more clear understanding of the steps of semantic analysis could aim towards this direction. This paper introduces a Business Process Modelling Notation (BPMN2) model that describes the process of conducting semantic analysis. Given that BPMN2 is the standard notation for business process modelling, it is the believe of the authors that a BPMN2 model for Semantic Analysis will make the use of the method more clear and easier to follow.


The purpose of this study was to determine the relationship between the quality of home environment that
parents provide for their children and the children's mental performance. The study focused on 64 children,
aged 5 to 6 years, from the Universiti Pertanian Malaysia Laboratory Preschool. Results of the study show that,
generally, most of the children came from a relatively supportive home environment. Consistent with past research,
the quality of home environment correlated with family background. Both parents' education and income
correlated with the quality of the home environment. The quality of the home environment correlated
significantly with the children's mental performance. Children from a cognitively stimulating home environment
achieved higher scores on all the subscales of the Weschler Preschool and Primary Scales of Intelligence.


Although the integration of SIP-based systems with a network address translation (NAT) environment has been investigated extensively, SIP-based system operation in symmetric model NAT remains relatively unexplored. This paper studies the application of symmetric NAT traversal techniques to SIP-based systems. This study focuses on following the SIP process, a non-additive service server, and employs standard SIP commands such as "REGISTER," "INVITE," and "200 OK" to predict and deliver the IP addresses and port numbers of the local NAT. This study also implements RTP streaming in the client-to-client (C2C) mode. The symmetric NAT traversal method for the SIP increases the direct peer-to-peer connection rate. This approach also avoids the STUN and RTP-Relay server. Experimental results with 50 types of NAT indicate that symmetric NAT traversal performs better than the STUN solution. The RTP-Relay server bandwidth cost is likewise superior to the TURN solution. These finding have important implications for SIP-based system developers and carrier providers.


 Instead of a dense, regular pattern of small clear-cuts and reserve blocks, where unharvested forest is rarely > 1 km from a clearcut, larger unharvested reserves should be incorporated into harvest planning, and be common on the landscape. Within the boreal forest a dynamic interplay is taking place between understory plants and bumble bees—bumble bees depend on flowers for their nectar and pollen, and flowers depend on bees for pollination. But what happens to this dynamic relationship when we introduce forest harvesting into the mix?


Background/Objectives: We studied the ventilated seats with amenities. The study has its purpose in checking the flow as affected by the shape of the ventilated seats and thereby acquiring the design factors.Methods/Statistical analysis: In order to acquire the design factors for ventilated seats as affected by the shapes and wind speeds of the different models, we used CATIA program to design the shape, of which the flow was analyzed with ANSYS CFX program. Thus, we have acquired the design factors for ventilated seats, which data can be used to ensure higher levels of efficiency as compared to the shapes before.Findings: For analyzing, we placed an inlet at the vent at the bottom and placed an outlet at the top by setting a boundary around it. From the setup, which had the initial wind speed at 15m/s, the wind speed within the boundary was 29.91m/s for model 1 and 44.81m/s for model 2. At the initial wind speed of 30m/s, we got a wind speed of 60.25m/s for model 1 and 88.60m/s for model 2. As for the pressure and speed in the flow path as the initial wind speed of 15m/s, we got the maximum pressure of 100.60kPa and the maximum speed of 29.45m/s. For model 2, we got the maximum pressure of 102.30kPa and the maximum speed of 44.81m/s. At the initial wind speed of 30m/s, we got the maximum pressure of 102.30kPa and the maximum speed of 60.25m/s for model 1. For model 2, we got the maximum pressure of 105.10kPa and the maximum speed of 88.60m/s.Improvements/Applications: Through the data obtained from this analysis, the varied seat structure for additional amenities can be improved and applied with more design factors.


This paper presents a new logic-based method for online power system fault diagnosis in a control center environment. The unique feature of the approach is the use of sequence of events recorder information from substations, together with data acquired by the energy management system (EMS). A proposed line fault proof algorithm is applied to a line if any protective device in the line's protection net is triggered. The method has been validated through testing with fault scenarios from the Italian power system.

Combined ocean bottom nodes and streamer surveys offer the best of both methods: the economy of streamers and the ability of nodes to cover obstructed areas. In the past we shown that up-going and down-going (mirror) imaging can be combined in a joint inversion. We have now extend the method to jointinversion of nodes and streamers data. Compared to conventional post-imaging merging, the joint inversion enhances resolution, suppresses migration artifacts, and more importantly, bring up the relative amplitude of true reflectors in the subfurface. We present a linearized inversion scheme for imaging narrow-azimuth (NAZ) and ocean-bottom data. Linearized inversion can enhance the resolution of the image, suppress migration artifacts, and increase the relative amplitude of true reflectors in the subsurface. We show that joint inversion can coherently combines the information from the two surveys and improve the image substantially. We demonstrate the concept and methodology in 2D with a synthetic Marmousi model.

Informatics, University of Minho, Portugal firstname.lastname@example.com https://www.di.uminho.pt/ ⇠ jcr Abstract. Major Minors is a project that collects press clippings from Portuguese newspapers (currently from 1996 until 2019) which refer subjects related with minorities. Its datasource is the Arquivo.pt (repository of the past Portuguese World Wide Web). This data was used to generate ontologies (RDF triplestores composing a semantic database) and interfaces to interact with them (SPARQL APIs following W3C standards for Semantic Web). We enriched this basis with new ramifications, by identifying and crossing references with 19 entities. This paper


SUMMARY We present an approach to articulated figure motion in which motion tasks are defined in terms of goals and ratings. The agents are dynamically-controlled robots whose behavior is determined by robotic controller programs. The controller programs for the robots are evaluated at each time step to yield torque values which drive the dynamic simulation of the motion. We use the AI technique of Genetic Programming (GP) to automatically derive control programs for the agents which achieve the goals. This type of motion specification is an alternative to key framing which allows a highly automated, learning-based approach to generation of motion. This method of motion control is very general (it can be applied to any type of motion), yet it allows for specifications of the types of specific motion which are desired for a high quality animation. We show that complex, specific, physically plausible, and aesthetically appealing motion can be generated using these methods.


Glyphosate-based herbicides are widely used for several crops, such as transgenic soybean and forestry. The aim of this study was to determine the effect of glyphosate on the community structure of riverine bacterioplankton and to evaluate the potential of bacterioplankton to degrade the herbicide. River water to which 13C-labelled glyphosate (10, 100µgL–1) was added or not (control) was incubated for 6 days at the temperature measured in situ (20°C). Significant differences in bacterioplankton community composition, as assessed by microfluidics-based automated ribosomal intergenic spacer analysis, were found among treatments, with differences in the presence of 100µgL–1 of glyphosate being more pronounced, namely significant decreases in bacterial richness and diversity. The glyphosate degradation product aminomethylphosphonic acid (AMPA) was detected, accounting for 1.2% of glyphosate conversion in water with 100µgL–1 of 13C-labelled glyphosate, together with a significant enrichment of 13C in the bacterial biomass. These findings suggest that glyphosate had a direct detrimental effect on most bacterioplankton taxa, but enriched those that were able to degrade the herbicide. Together, the results indicate that glyphosate degradation in the river assessed would be a slow process (months–years), taking place through the AMPA degradation pathway and meaning glyphosate accumulate in the ecosystem.


The Affordable Care Act includes a 2.3% tax on domestic sales of medical devices, paid by the manufacturer, which went into effect in January. But after intense industry lobbying, the Senate has voted overwhelmingly, in a nonbinding resolution, to repeal the tax.


[1] The occurrence characteristics of Jovian quasiperiodic (QP) bursts at a VLF range ( ∼20, and QP bursts could have beaming angles like "filled cone" in a restricted L value range or have a large source L value range with beaming angles like "hollow cones." These results imply that QP bursts observed at low latitudes are generated at fRX surfaces in the polar region and propagate to the equatorial region.


Advances in technology and the human tendency to use virtual services are constantly increasing in all areas of life. Online ride-hailing services are not an exception to this rule. Due to the financial transactions in these systems, the possibility of fraud by profiteers also increases which can affect the revenue of such services significantly. In this paper, we propose a system that can detect fraud in online ride-hailing systems. We address frauds that occur using the ride collusion method or creating a fake ride using GPS spoofing applications. We have used real unlabeled data from one of the largest ride-hailing companies in Iran for this purpose. Our system first identifies the most important features that help us distinguish real rides from fake rides, then it uses unsupervised learning methods to detect ride anomalies. After identifying the anomalies and examining these rides, we label the data, and use supervised learning methods to construct the fraud detection model.


The use of computers changes the way that individuals relate to one another and to organizations, and it may appear to change rights and responsibilities in these relationships. There is a sharp distinction between the empirical questions and the normative questions that might be raised about the use of computers. It is argued that philosophical, ethical analysis is needed when the moral rules relevant to a situation are not obvious, or when several moral principles come into conflict. Three such areas center around rules regarding property, privacy, and power. Issues surrounding rights of ownership of computer programs are explored; the effects of increasing use of computers on personal privacy and organizational power are examined; and effects on the distribution of power are considered.


yThe model in this paper illustrates three effects of vertical mergers when both stages are oligopolistic and vertically integrated and unintegrated producers coexist. First, the merging firm increases its final good output. Second, the resulting backward shift in the residual demand curve facing unintegrated final good producers ylowers their demand for the intermediate good. Third, the merged firm withdraws from the intermediate good market. The increased concentration pushes the intermediate good price upward. Which effect dominates depends on market structure. Under some conditions, a vertical merger causes the price of the final good to increase.

The "International Ultraviolet Explorer (IUE) Battery History and Performance" report provides the information on the cell/battery design, battery performance during the thirty eight (38) solar eclipse seasons and the end-of-life test data. It is noteworthy that IUE spacecraft was an in-house project and that the batteries were designed, fabricated and tested (Qualification and Acceptance) at the Goddard Space Flight Center. A detailed information is given on the cell and battery design criteria and the designs, on the Qualification and the Acceptance tests, and on the cell life cycling tests. The environmental, thermal, and vibration tests were performed on the batteries at the battery level as well as with the interface on the spacecraft. The telemetry data were acquired, analyzed, and trended for various parameters over the mission life. Rigorous and diligent battery management programs were developed and implemented from time to time to extend the mission life over eighteen plus years. Prior to the termination of spacecraft operation, special tests were conducted to check the battery switching operation, battery residual capacity, third electrode performance and battery impedance.


This paper quantifies the impact of demand uncertainty and time to build on prices, investment and surplus in the world bulk shipping industry. We explore the impact of both construction lags and the lengthening of delivery lags in periods of high investment activity by constructing a dynamic model of ship entry and exit. A rich dataset of second-hand ship sales provides direct information on key dynamic objects of the model and allows for their nonparametric estimation. We are able to estimate a ship's value function directly and use it to recover entry costs, scrap values and per period payoffs. We find that moving from time-varying, to constant, to no time to build reduces the level and volatility prices, while increasing entry and consumer (i.e. shipper) surplus. As the duration of time to build can be steered by shipbuilding subsidies, the findings of this paper provide also a first step in examining the impact of such subsidization programs -prevalent in China, South Korea and Japan- on the shipping industry.


The principle result of this paper is the following disturbance rejection control scheme for a class of nonlinear dynamical systems. By using the internal model principle, the problem of disturbance damping control is converted into a nonlinear quadratic regulator (NQR) problem for an undisturbed augmented system. Then, an iterative technique is designed to solve this NQR problem effectively. The proposed iterative method is also extended through the use of a nonlinear model predictive control in an offline framework. In this case and in the presence of unknown disturbances, the Lyapunov stability of the closed‐loop system is guaranteed. Numerical simulations and comparative results verify the effectiveness of the proposed approach.


Fecal water content(WC) and mean particle size(MPS) reflect the capacity of water balance and chewing efficiency in ungulates,which are important strategies for ungulates to survival under particular environments.How to adapt to arid environments is an important research project of Reintroduction of Przewalski's horses.We collected totally 65 fresh feces of releasing horses during spring,summer,and autumn in the Kalamaili Nature Reserve,Xinjiang,China,and we measured the water content and particle size(wet sieving method) of these feces,then compared the seasonal and sex differences.The results show that the MPS was significantly higher in spring(3.98 ± 0.08 mm) than in summer(3.65 ± 0.05mm);MPS of the stallions was significantly higher than that of the female horses in the spring,but there were no significant differences in summer and autumn.WC of total horses in spring(73.17 ± 1.05%).summer(70.56 ± 0.99%),and autumn(68.12 ± 0.79%) decreased gradually,but no significant difference was found.WC of stallion was higher than that of the mares in each season,and the difference was significant in the spring.This study shows that the variation in WC and MPS of releasing Przewalski's horses may be related to the availability of food and water sources,and may be related to their role in the population,too.


Probes featuring room temperature phosphorescence (RTP) are promising tools for time-resolved imaging. It is worth noting that the time scale of time-resolved bioimaging generally ranges microsecond level, because of the short-lived emission. In this report, the first example of millisecond-range time-resolved bioimaging is illustrated, which is enabled through a kind of ultralong aqueous phosphorescence probes (i.e., cyclo-(Arg-Gly-AspD-Tyr-Cys)-conjugated zinc-doped silica nanospheres), with RTP emission lasting for ~5 s and lifetime as long as 743.7 ms. We demonstrate that the live cells and deep tumor tissue in mice can be specifically targeted through immune-phosphorescence imaging, with a high signal-to-background ratio (SBR) value of ~69 for in vitro imaging, and ~627 for in vivo imaging, respectively. We further show that, compared to that of fluorescence imaging, the SBR enhancement of millisecond-range time-resolved in vivo bioimaging is up to 105-times.


— While policymakers place great importance on foreign direct investment (FDI) in advancing development in developing countries, the links between FDI, economic development, and human development remain tenuous. We attempt to better understand these relationships by looking at the influence of FDI policy and corruption on these relationships. We find that FDI inflows are more strongly positively related to improvement in human development when FDI policy restricts foreign investors from entering some economic sectors and when it discriminates against foreign investors relative to domestic investors. The relationship between FDI and improvement in human development is also more strongly positive when corruption is low. 2010 Elsevier Ltd. All rights reserved.


An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. This paper compared the performance of two prominent on-demand reactive routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR) and Ad Hoc On-Demand Distance Vector Routing (AODV), along with the traditional Proactive Destination-Sequenced Distance-Vector (DSDV) protocol. A simulation model with Media Access Control (MAC) and physical layer models are used to study interlayer interactions and its performance implications. The on-demand protocols, AODV and DSR perform better than the table-driven DSDV protocol. Although DSR and AODV share similar ondemand behavior, the differences in the protocol mechanics can lead to significant performance differentials. The performance differentials are analyzed using varying network load, mobility and network size.


Deforestation has been a very critical environmental problem during the past few decades. Monitoring the forest land use conditions and their changes are essential to the management of this global environmental problem. Remote sensing can provide an effective tool for monitoring land use and environmental changes on regional as well as global scale. This has focused attention on developing more effective and efficient techniques for the management and survey of land use and forest areas. This study was designed to assess the feasibility of utilizing Landsat TM image in classifying the vegetation in the Sundarbans reserve mangrove forest. Vegetation classification was performed using satellite image taken in 1996 and supported by 2001 image. An IDRISI image processing system was used to analyse the satellite data. The images were registered and spectral signatures of each point on band 2, 3, and 4 were directly compared with the false colour composite image (FCC). Correlation analysis was used to evaluate the similarity of two spectral signatures. A false colour composite image of bands 2, 4 and 3 (Red-Green-Blue) was used in visual interpretation and unsupervised classification. The study classified the mangrove vegetation in nine categories in the Sundarbans reserve mangrove forest with an accuracy of 78.32 and 81.62 per cent in unsupervised and supervised classification respectively. Thus it appeared that the GIS and remote sensing are effective techniques for classifying the mangrove vegetation.


Engineers are increasingly required to work in teams that spantime zones and cultures.Engineering education hasbegun toattempt to prepare students for this environment. An important topic is how to best form teams of students for distributeddesign projects. The goals of this research were to validate a method for organizing teams to maximize team performanceand identify and validate metrics for individuals that would help in the organization of distributed teams of studentengineers. A review of previous, related research is provided. A description of the proposed method of team organization isgiven, along with methods of data collection and a comparison of the proposed method to common methods. Howstudents were divided into teams and each team's method of organizing sub-teams are described. Use of online surveys,tests, statistical methods, and other data gathering and analysis methods are explained. Statistical analysis of survey resultsand qualitative results of interviews and observations suggest that a profile-based method for organizing teams results insignificantly higher team satisfaction. Some methods for measuring and/or predicting individual attributes related toteamwork, such as the significance of participation in team sports, were validated. No correlation was found betweenwhich university a student attended and a student's level of satisfaction with his or her team. Team success in distributed,multi-disciplinary student design teams can be improved by gathering information about team members and using aprofile-based method to organize team members into sub-teams and leadership positions.

In this manuscript, we investigated the accuracy of the entire chain of phase space files generated by the TrueBeam VirtuaLinac system in clinical treatment plans. Good agreement was obtained between the MC simulation and the clinical golden data for both flattened and FFF beams. The relative magnitude of agreement between MC and golden beam data presented in this research may assist a physicist in terms of the percent dose deviation that one may expect when using MC data for verification purposes.


This paper examines share price of the companies listed on the WIG-Ukraine and their fair value between 2011-2015. Data from Q4 2013 to Q2 2014 was collected from the Stooq.pl (Polish portal of shares). Two hypotheses are tested: (1) value of the shares based on the market price; (2) value of the shares as the fair value of shares. In this paper, the WIG-UKRAINA stock exchange sector companies, which oppose a bad economic situation in Ukraine caused by military actions on its territory, were analysed. These companies were subject to detailed research in order to demonstrate that they have the potential to act on the free market and that they do not lose their financial liquidity. In addition, their fair value was shown, because the current economic and market situation in Ukraine completely deprived it of this value.


The banning of the hijab along with other religious symbols in French public schools from 1st September 2004 can be cited as an example of a complex issue. It is also an example of policy making, that treats the wearing of the hijab (and other religious symbols) as representative of an essentialist religious category that is symbolic of both identity and worldview. All religious symbols in public schools are banned, but the discretion is with local schools as to how the law will be managed through discussion with the student. This article addresses the policy by 'unfolding' the values of the different stakeholders and 'sweeping in' the social, cultural, political, economic and environmental factors (adapted from Churchman, 1979a, b, 1984, who cites Edgar Singer). Both cultures Christian and Muslim need to consider the merits of using the least powerful as a site for the struggle over identity politics, shorthand for the systemic fall out post 9/11.

This paper presents an abstract interpretation-based formal description of data obfuscation, which makes it possible to formally analyze and certify not only the correctness but also the potency of data obfuscating transformations. First, a semantic data obfuscating transformation is given, which is expressed as an abstract interpretation of program semantics with a variable obfuscation function and a corresponding variable deobfuscation function. Then, the syntactic data obfuscating transformation is systematically derived by composition of source-to-semantics, semantics-to-data obfuscating transformed semantics and semantics-to-source abstractions applied to fix-point trace semantics.

W1D is a wellbore simulator developed as part of the GEOTREF (GEOThermal energy in Fractured REservoirs) project. A coupled system of equations ensuring mass, momentum and heat balance with appropriate set of models and correlations is resolved to describe multi-component and multi-phase flow along the well axis. The simulator is designed to be effective as a practical tool in the monitoring of geothermal systems. In the present work, the code is used to carry out physical investigations on the water boiling occurring alongside the degassing of a non-condensable gas, the carbon dioxide (CO2). For high Reynolds flows in geothermal wellbores, it is illustrated that a thermodynamical approach with appropriate assumptions is able to accurately capture the effect of local physical mechanisms (such as the interfacial mass transfer resistance) on the global dynamic (partitioning of CO2 in liquid and gas phases). INTRODUCTION The energy challenge is one of the greatest issues we are to face in the near future. The need to satisfy the increasing demand in energy and to significantly reduce at the same time our environmental impact in order to fight against the global warming issue, leads us to develop sustainable energy for large scale supply. Geothermal energy can be seen as a part of the solution as it has very low impact on the environment (almost no greenhouse gas emission) and high rate of availability. However, the field finds it difficult to attract stockbroking for mainly two reasons: Great risk to the investor at the upstream part of the project: very high drilling cost, geological risks remain high (exploration & prospecting cost) and very little investment from public organizations (strategy & funding) -The very low price of fossil energy (oil, gas, coal) The present work is part of the GEOTREF project, a multidisciplinary platform for innovation and demonstration activities for the exploration and development of high GEOThermal energy in Fractured REservoirs, financially supported by the French government. It has for ambition the development of innovative and practical tools to trigger private investments into the field [8]. The project consists in improving our understanding of fractured geothermal reservoirs during exploration and production phases. It can be divided into two parts. On the one hand, developing innovative tools that would help industrials to carry out reliable feasibility and exploitation studies and smartly manage a reservoir at the production state. On the other hand, providing a demonstration in Guadeloupe (French West Indies in the Antilles islands of the Caribbean) so as to prove the practical capabilities of developed tools. Thus, a positive reinforcement is spread, expecting that it would stimulate investments in the geothermal field. The interest on multi-component systems raised among the geothermal professional community as soon as the pure water approximation was not able to give a satisfactory description of recorded pressure and temperature profiles in wells. Indeed, dissolved non-condensable gas, even in low amounts, has a significant impact on the boiling onset conditions. It increases for instance the vapor pressure of water leading to early flashing in geothermal production wells. Severals codes have then been developed to simulate multi-component systems. One can mention for instance the EWASG module for the TOUGH2 reservoir simulator [3; 4] or the wellbore simulator PROFILI [5] based on the work of [2]. Reactive chemical transport has also been considered by [6; 7]. The effect of the non-condensable gas is included in wellbore codes [2] and enables to capture the correct flashing point along the well. In this paper, we will focus on the physical aspect of the boiling in presence of a non-condensable gas. The wellbore flow model is first derived and validated on recorded data from Japanese wells[9]. Then the model to describe the effect of a non-condensable gas on the boiling mechanisms is presented and validated on recorded data form the well NG11 (Ngawa field, New Zealand) [10]. Finally, physical investigations are carried out to portray the complex thermodynamical path followed by the boiling of a pure fluid when it is coupled to the degassing of 13th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics

Due to their collective nature Casimir forces can strongly depend on the geometrical shape of the interacting objects. We study the effect of strong periodic shape deformations of two ideal metal plates on their quantum interaction. A nonperturbative approach which is based on a path-integral quantization of the electromagnetic field is presented in detail. Using this approach, we compute the force for the specific case of a flat plate and a plate with a rectangular corrugation. We obtain complementary analytical and numerical results which allow us to identify two different scaling regimes for the force as a function of the mean plate distance, corrugation amplitude, and wavelength. Qualitative distinctions between transversal electric and magnetic modes are revealed. Our results demonstrate the importance of a careful consideration of the nonadditivity of Casimir forces, especially in strongly nonplanar geometries. Nonperturbative effects due to surface edges are found. Strong deviations from the commonly used proximity force approximation emerge over a wide range of corrugation wavelengths, even though the surface is composed only of flat segments. We compare our results to that of a perturbative approach and a classical optics approximation.


The Lean Startup Method (LSM) provides a systematic management of innovation processes within startups and even within well-established companies. Despite its wide use by a lot of innovative companies, this study claims that using the LSM compromises the development of breakthrough and radical innovations and also companies' innovativeness is hindered given that companies usually follow the method and its principles blindly, without fully understanding its advantages and disadvantages. The aim of this study is to make a critical analysis of the LSM with focus on the above two statements and to test the critical findings from the analysis with the help of innovation experts. The methods employed in the study are mainly statistical ones like Pearson correlation, linear regression and statistical mean. The results show that innovation experts generally do agree with the formulated critical points (CPs) in the research but still use the method because they had not been aware of these disadvantages before entering the research as respondents. Another finding is the negative correlation between commercializing breakthrough innovations and using customers in the innovation development process. The contribution of the paper for the readers is mainly related to the impact of customer utilization within the breakthrough innovation development process and how using the LSM might compromise companies' innovativeness in general.

Abstract Results are reported from seven heat flow stations in small basins of the southern part of the central Scotia Sea (CSS), undertaken in order to determine basement ages. The basins are small, which makes magnetic anomaly-based ages ambiguous and preserves basin subsidence that may have been anomalous as a result of local factors. The fact that these small basins formed in a back-arc setting adds additional uncertainty to depth-based age estimates. The results confirm that basin extension commenced in the Eocene, and indirectly support a relatively young, back-arc origin for the northern CSS, but do not affect previously published suggestions of the age of onset of the Antarctic Circumpolar Current.

However, the implementation of DOACs was slow and varied across different health economies in England. There is limited evidence on the patient role in the uptake of new medicines, including DOACs, apart from considering their demographic and clinical characteristics. Hence, this study aimed to address the gap by exploring the view of patients with AF on factors affecting DOAC use. Methods: A qualitative study using semi-structured interviews was conducted in three health economies in the North of England. Adult patients (>18 years) diagnosed with nonvalvular AF, prescribed an oral anticoagulant (vitamin K antagonist or DOAC), and able to give written consent were recruited. Data were collected between August 2018 and April 2019. Audio recorded interviews were transcribed verbatim and analyzed using the framework method. Results: Four themes with eleven subthemes discussed identified factors affecting the use of DOACs. They were linked to limited healthcare financial and workforce resources, patient involvement in decision-making, patient knowledge about DOACs, safety concerns about oral anticoagulants, and oral anticoagulant therapy impact on patients' daily lives. Lack of a) opportunities to voice patient preferences and b) information on available therapy options resulted in some patients experiencing difficulties with the prescribed therapy. This was reported to cause negative impact on their daily lives, adherence, and overall satisfaction with the therapy. Conclusion: Greater patient involvement in decision-making could prevent and resolve difficulties encountered by some patients and potentially improve outcomes plus increase the uptake of DOACs.

The work presented in this paper concerns Global Environment, focusing on Natural Risk Monitoring: our application is volcanic activity monitoring.
The real-time data used in such a system generally comes from an array of sensors and are usually collected into a central database. With the now widespread addition of GPS, these data therefore have both temporal and spatial components.
Therefore a major trouble encountered is the data structuring, so that it can store data effectively and process real-time queries on real-time objects.
Our work offers a new indexing method dealing with multi-dimensional aspects of the data as well as storing and real-time querying
