In this work, we used atmospheric pressure plasma in ambient air generated by diffuse coplanar surface barrier discharge [1] to treat polypropylene non-woven textiles in order to increase their surface energy prior deposition of poly(L-lactide) nanoparticles containing antimicrobial agent octenidine, that can be released when nanoparticles are in contact with bacteria. Untreated textiles showed poor surface properties and distribution of particles was uneven and remained on the textile surface. Short plasma treatment time led to fast hydrophilization of the textiles and penetration of particles into textile volume. This work is mainly focus on the advantages of atmospheric plasma treatment technology, while antibacterial particles are described in our previous work [2]. We have investigated plasma treatment efficiency by means of strike-through-time measurements and linked these findings with XPS data of untreated and plasma treated surfaces. SEM showed that distribution of particles formed a crust on the untreated non-woven textiles surface, whereas plasma treatment textiles showed particles distributed evenly in the volume of treated material. Plasma had no damage influence on textiles which consist of thin fibres. We have demonstrated that the plasma system can be also integrated within roll-to-roll line and nanoparticles can be delivered on the textiles using ink jet printing.

We have read with great interest the paper by WEST et al. [1], regarding the stress failure mechanism of pulmonary capillaries in the pathogenesis of high-altitude pulmonary oedema (HAPE), and would like to add some considerations. HACKETT et al. [2] described a high incidence of HAPE in subjects without the right pulmonary artery. Recently, we have reported a case of unilateral, left sided HAPE in a subject with a right pulmonary artery hypoplasia [3], that also underlines the importance of a restricted pulmonary vascular bed in the development of HAPE. Other reports of HAPE have been described in association with a congenital [4, 5] or acquired [6] pulmonary artery occlusion. In these subjects, HAPE usually occurs at moderate altitude and is sometimes recurrent [5, 6]. All these observations confirm the HAPE susceptibility in subjects with pulmonary artery abnormalities and are consistent with the pathogenetic mechanism proposed by WEST and MATHIEU-COSTELLO [7]. In people without anatomical defects of the pulmonary vasculature the most likely hypothesis is that proposed by HULTGREN [8]: an uneven pulmonary vasoconstriction, that leads to high pressure in the non-vasoconstricted pulmonary vessels. This hypothesis is supported by the radiological appearance of a patchy pulmonary oedema and by the increased and uneven pulmonary perfusion in HAPE susceptible subjects after hypoxic breathing [9]. Although not yet proven in humans, stress failure of pulmonary capillaries appears to be the best model to explain the pathogenesis of HAPE. References


CoNi ferrite thin films were prepared for perpendicular magnetic recording media by spin-spray ferrite-plating method. In this paper, solution conditions for CoNi ferrite plating were optimized to increase coercivity Hc⊥ and remanence ratio (Mr/Ms)⊥ in perpendicular direction to the film plane. By adjusting the deposition rate, the concentration of NaNO2 to optimize the ratio of Fe2+ to Fe3+ in the films and the concentration of CH3COONH4 to optimize pH in oxidizing solution, CoNi ferrite films with Hc⊥ of 3200 Oe and (Mr/Ms)⊥ of 0.6 were obtained without any heattreatment. Disk media prepared under the optimized solution conditions exhibited reproduced waveforms of dipluse shape and better frequency responses than that with lower Hc⊥ and (Mr/Ms)⊥.

In this report, the intercomparison of radionuclide measurement with γray spectrometer for environmental samples organized by State Environmental Protection Administration recently was introduced. The activities of 238 U, 226 Ra, 232 Th and 137 Cs in two soil samples and 137 Cs and 134 Cs in a biological sample were measured by 14 participating laboratories. The intercomparison has achieved great success, while some problems arising in the measurement results were also discussed.


Pneumocystis Carinii pneumonia most often occurs in debilitated infants and children or those with more specific alterations of the immune mechanism. The characteristic clinical picture is one of progressive respiratory distress and cyanosis, with relatively few physical findings pertaining to the thorax. The roentgen findings are those of diffuse, granular pulmonary infiltrates which progress from the hili toward the periphery of the lung, becoming more and more confluent. Interstitial emphysema may be present and, not infrequently, pneumothorax and pneumomediastinum. Pleural reaction and hilar lymphadenopathy are absent. Although the roentgen findings are not specific with respect to the etiologic agent, when they are correlated with the clinical picture, the presumptive diagnosis of pneumonia due to Pneumocystis Carinii may be made.


There are a large number of plants whose anthelmintic activity has been demonstrated under controlled experimentation, either through feeding the whole plant or administering plant extracts to parasitised hosts. However, contrary to traditional expectation, there are also a great number of plants with purported antiparasitic properties, which have not been reproduced under experimental conditions. Studies on the helminthicidal activities of leaf extract of Mangifera indica+root extract of Nauclea latifolia in mice was designed to determine their efficacies against intestinal helmithes. Sixty Swiss albino mice maintained conventionally were selected randomly from laboratory animal house. The collected faecal samples were examined by simple faecal flotation techniques for isolation of parasitic eggs and/or oocysts. 42 (70.0%) of the mice under study were infected with at least one gastro intestinal parasite. The leaf extract of Mangifera indica+root extract of Nauclea latifolia was prepared by boiling in tap water. Graded concentrations (100%, 50%, 25% and 12.5%) of stock that was produce in Tetfund Zoology Laboratory of Osun State University was tested against both mice of different weights and sexes for helminthicidal efficacy. LC50 of the extract value obtained was found to be 75 mg/l in both big and small mice. Prevalence of gastrointestinal infections reduced with increased concentration of extract. Statistical analysis using analysis of variance indicated that there was a significant difference in the means of the treatment concentrations and the rates of prevalence of gastrointestinal infections in the sampled mice. The results of this research showed that the leaf extract of Mangifera indica+root extract of Nauclea latifolia are highly active against intestinal helminths in the sampled mice. The extract action also had significant influence (p>0.05) on the time of exposure of mice and the rate of prevalence. The safety of the leaf extract of Mangifera indica+root extract of Nauclea latifolia on vital organs of humans may need to be investigated to determine its safety on humans.


Objective: Tideglusib is a GSK-3 inhibitor activating Wnt/β-catenin signaling pathway which has significant importance in regenerative response. The aim of this study was to evaluate the cytotoxicity and protein expression impacts of Tideglusib on human periodontal cell lines. Methods: Cytotoxicity effect of different concentrations (50nM, 100nM, 200nM) of Tideglusib application on human gingival fibroblast (hGF), periodontal ligament fibroblast (hPDLF), and osteoblast (hOB) cell lines was determined. Type-I and III collagen expressions were evaluated after 24-hour application of 50nM Tideglusib. Results: The cytotoxicity of 200nM Tideglusib was higher in hGF and hOB (p 0.05). The hGF and hOB treated with 50nM Tideglusib expressed an increased level of Type-I collagen (p 0.05). Type-III collagen expressions were similar between the test and control groups for each cell line (p>0.05). Conclusion: Tideglusib is not cytotoxic at 50nM and 100nM concentrations and may have positive effect on bone regeneration rather than periodontal regeneration since it stimulated Type-I collagen production in hGF and hOB cells, but not in hPDLF.


Soil-transmitted helminth infection is endemic in Indonesia, with cases of reinfection despite individualized therapy and a mass treatment program. Three cases of multiple helminth infections were described that might be associated with chronic bloody diarrhea and stunted growth. These case series alert pediatricians that untreated helminthic infections are part of the differential diagnosis in children with gastrointestinal bleeding. Environmental surveillance should be performed in high-risk areas to prevent reinfection and growth alteration. In endemic areas, bloody diarrhea warns for an early routine fecal analysis. Correct diagnosis, prompt treatment, and source control are crucial to prevent long-term complications.


Aim To investigate the short- and long-term effects of home-based pulmonary rehabilitation (HBPR) on functional capacity, quality of life, peripheral muscle strength, dyspnoea and daily physical activity in people with bronchiectasis. Methods Randomised controlled trial with 63 participants with bronchiectasis. The HBPR group performed three sessions per week for 8 weeks (aerobic exercise: step training for 20 min; resistance training: exercises for quadriceps, hamstrings, deltoids and biceps brachii using elastic bands). The control group received a recommendation to walk at moderate intensity, three times per week. A weekly phone call was conducted for all participants, and the HBPR group received a home visit every 15 days. The primary outcome was distance in the incremental shuttle walk test (ISWT). Secondary outcomes were time in the endurance shuttle walk test (ESWT), number of steps in the incremental step test, quality of life, quadriceps muscle strength and daily physical activity. Measures were taken before and after intervention and 6 months later. Results After the intervention, the HBPR group had increased ISWT distance compared with the control group with between-group difference 87.9 m (95% CI 32.4–143.5 m). In addition, between-group differences were found in the ESWT, incremental step test, quality of life and quadriceps muscle strength, favouring the HBPR group. After 6 months, no differences were observed between the groups. Conclusion HBPR is an effective alternative offering of pulmonary rehabilitation for people with bronchiectasis. However, the programme was not effective in maintaining the benefits after 6 months of follow-up. Home-based pulmonary rehabilitation (HBPR) delivers improvements in functional capacity, peripheral muscle strength and QoL in people with bronchiectasis. HBPR is safe, well tolerated and can be considered an alternative rehabilitation programme. https://bit.ly/2Q2Bout


P emphigus vulgaris (PV) is a chronic autoimmune blistering disease associated with a high morbidity rate and potential mortality. Current therapies are not uniformly effective and are associated with potential adverse effects; thus, there is a need for new therapeutic options for PV. Data from in vitro experiments and mouse models suggest that tumornecrosis factor (TNF)hasa role inPVpathogenesis. Etanercept is a recombinant fusion protein of the extracellular ligand-bindingdomainofhuman75-kDaTNF receptor and the Fc portion of human IgG1 that acts as a competitive inhibitor of TNF. We conducted a pilot study to evaluate the efficacy and safety of etanercept for PV therapy.


Clinical Neuroscience Lab , Universi ty of Califor nia, Los Angeles (UCLA), USAAbstractAlthough the underlying neurobiology of emerging psychotic disorders is not well understood, evidence from structuralimaging and other studies support the notion that schizophrenia arises as a consequence of both an OearlyneurodevelopmentalO disturbance, as well as Olate neurodevelopmentalO changes occurring during the initial stages of apsychotic illness, including around the time of transition to illness. In line with this, our longitudinal MRI findings inindividuals at ultra-high risk for developing a psychotic illness show that there are excessive neuroanatomical changes inthose who convert to psychosis. These aberrant changes are observed most prominently in medial temporal and prefrontallobe regions. In a further series of longitudinal studies in first-episode psychosis, we have identified changes in prefrontalregions that indicate an accelerated loss of grey matter in patients compared to healthy control subjects. We suggest thatthe available evidence is consistent with the presence of subtle regionally and temporally specific neurobiological changesthrough the course of psychosis (Pantelis et al., 2005), including: (1) evidence for early (pre- and peri-natal)neurodevelopmental anomalies, (2) evidence for progressive grey matter loss involving medial temporal and orbitalprefrontal regions around the time of transition to illness, and (3) evidence of late (post-pubertal) neurodevelopmentalchanges soon after the onset of psychosis, involving an acceleration of normal brain maturational processes, associated withsignificant loss of grey matter in dorsal prefrontal regions. The pathological processes underlying such changes remainunclear and may reflect anomalies in genetic and/or other endogenous mechanisms responsible for brain maturation, theadverse effects of intense or prolonged stress, or other environmental factors. These findings suggest that early markers ofimpending illness may prove difficult to define, and that brain changes in psychosis may better be conceptualized asanomalous trajectories of brain development. Further, active changes during transition to illness may present the potential tointervene and ameliorate these changes with potential benefit clinically.


Terra, the third largest cryptocurrency ecosystem after Bitcoin and Ethereum, collapsed in three days in May 2022 and wiped out $50 billion in valuation. At the center of the collapse was a run on a blockchain-based borrowing and lending protocol (Anchor) that promised high yields to its stablecoin (UST) depositors. Using detailed data from the Terra blockchain and trading data from exchanges, we show that the run on Terra was a complex phenomenon that happened across multiple chains and assets. It was unlikely due to concentrated market manipulation by a third party but instead was precipitated by growing concerns about the sustainability of the system. Once a few large holders of UST adjusted their positions on May 7th, 2022, other large traders followed. Blockchain technology allowed investors to monitor each other's actions and amplified the speed of the run. Wealthier and more sophisticated investors were the first to run and experienced much smaller losses. Poorer and less sophisticated investors ran later and had larger losses. The complexity of the system made it difficult even for insiders to understand the buildup of risk. Finally, we draw broader lessons about financial fragility in an environment where a regulatory safety net does not exist, pseudonymous transactions are publicly observable, and market participants are incentivized to monitor the financial health of the system. ∗Jiageng Liu: E62-685, 100 Main Street, Cambridge MA 02138, USA.

The performance of a spray liquid-liquid extraction column at two mass-transfer directions was experimentally studied in the presence of silica nanoparticles. Toluene-based nanofluid drops containing 0.0005–0.01 vol % silica nanoparticles were dispersed in aqueous phase and acetic acid (AA) transfer between phases was investigated. The experiments were performed at fixed volumetric flow rates of dispersed and continuous phases. Maximum enhancement of 47.4% and 107.5% in overall mass-transfer coefficient, respectively, for mass-transfer direction of dispersed to continuous phase and vice versa were achieved for drops with 0.001 vol % silica nanoparticles. These enhancements can be referred to Brownian motion of nanoparticles and induced microconvection. The results showed that nanoparticles are more effective in augmenting AA transfer from continuous to dispersed phase. Probable reason is that smaller diameter and lower internal turbulence of drops in this transfer direction increase dispersed phase resistance potential to be manipulated by Brownian motion of nanoparticles. © 2015 American Institute of Chemical Engineers AIChE J, 2015


Purpose: To determine the effect of miR-30a-5p on hepatoma cell radiosensitivity and elucidate the underlying mechanism.Methods: Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used tomeasure miR-30a-5p expression in HepG2 and THLE-3 cells. After 4-Gy X-ray irradiation or miR-30a-5p mimic transfection, the miR-30a-5p level in HepG2 cells was determined using qRT-PCR. Luciferase reporter assay was used to confirm the correlation between miR-30a-5p and glucose-regulated protein 78 (GRP78) levels, while the effects of miR-30a-5p on the viability of HepG2 cells were determined using clone formation and 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assays. Apoptotic cells were evaluated by flow cytometry whereas the protein levels of GRP78, B-cell lymphoma-2 (Bcl-2), BCL2-Associated X Protein (Bax), and cleaved-caspase-9 were quantified by immunoblotting.Results: MicroRNA-30a-5p expression was decreased in HepG2 cells but reduced after 4-Gy x-ray treatment, while miR-30a-5p mimic transfection upregulated miR-30a-5p expression (p < 0.05). Cell viability was inhibited after x-ray irradiation or miR-30a-5p mimic transfection and further inhibited by irradiation + miR-30a-5p (p < 0.05). Irradiation or miR-30a-5p transfection triggered cell apoptosis; however, irradiation + miR-30a-5p induced more apoptosis, upregulated Bax and cleaved-caspase-9 expression, and reduced Bcl-2 expression (p < 0.05). MicroRNA-30a-5p also suppressed GRP78 expression.Conclusion: MicroRNA-30a-5p may enhance HCC x-ray radiosensitivity by inhibiting GRP78., and may be useful in developing treatment strategies for HCC patients.


The purposes of this study were to expose the dangers of doping practiced by Algerian teenager (18years) who practices bodybuilding and wants to seek results in the shortest time. From that, our subjects were five (5) Algerian teenager who practices bodybuilder for 5years ago and who volunteered accepted to involve doping as first experience in their practices. Our study based on the follow Analysis of blood, urine, and anthropometric measurements for two months where our work was divided into two team –research: Field team1 and a Lab team2. To verify the hypothesis that support: Doping gives good visual results anthropometric external in addition, it destabilizes the regulation of vital functions. From that, our aims for this study interest: (1) Are there any statistically significant differences anthropometric between the two tests of our sample? (2) Are there any statistically significant can explain destabilizes regulation of vital functions between the two tests of our sample? For that, we have chosen the analysis of T-TEST PAIRS and correlation of the volunteer involve doping practiced by our sample to compare the implementation differences anthropometric and differences of modification in the regulation of the vital functions. Based in the results accuses in two months we confirm: (1) that the Doping gives good visual results anthropometric; (2) Doping destabilizes the regulation of vital functions


This paper describes the electric corrosion due to the air space discharge between ADSS and the gripping section of spiral vibration damper. It has been found that the discharging electricity of air space between ADSS and the gripping section of spiral vibration damper is the main reason for causing failures of the installed ADSS cables. Firstly, this paper describes the electric corrosion mechanism due to the air discharge between ADSS and the gripping section of spiral vibration damper. The analytical methods are based on electromagnetic theory. Then secondly, in order to inhibit this type of electric corrosion, we have already developed the anti-corrosion paint, which can be used to fill up the space between ADSS and the gripping section of spiral vibration damper. In order to demonstrate the resistance of the anti-corrosion paint to erosion, the salt fog test has been carried out. The test results indicate that the ADSS cable with the anticorrosion paint has a higher corrosion resistance and reliability. Finally, we have also introduced the new developed excellent track resistant cable sheath, the anti-corrosion spiral vibration damper and lighter stockbridge damper, which can also improve the corrosion resistance of the ADSS cable significantly.


Now a days the construction industry faces major problems is the easy availability of fine aggregate. Sand is a prime material used for preparation of concrete structures making nearly 40% of volume of concrete used in construction industry. The non-availability or shortage of river sand will affect the construction industry; hence there is a need to find the new alternative material to replace the present fine aggregate. Many researchers are finding different materials to replace sand, as a whole the studies main concerns on the environment and the construction. This paper deals with the possibility of fine aggregate to be replaced by processed sand in various proportions such as 0%, 20%, 40% and 60%. The aim of the project is to study the strength and durability performance of concrete made with fine aggregate and processed sand. The maximum compressive strength of concrete attained at 40% replacement of fine aggregate at 7, 14, and 28 days.


In the case of S.A.S./FR the European Court of Human Rights declares that a general ban on wearing clothing that conceals the face is in conformity with the Convention. The Court concludes that the ban is necessary and proportionate to achieve the legitimate aim of protecting the rights and freedoms of others, namely the "right of others to live in a space of socialisation which makes living together easier". However, such a right is neither guaranteed by the Convention nor French law. An analysis of the jurisprudence shows that in fact the "right to live in a space of socialisation which makes living together easier" leads to a right to prevention of disorder. But according to the Court this legitimate aim could not justify the interference in question. In conclusion, the Court's reasoning is inconsistent and diverges from its former jurisprudence.


Submitted for the DFD06 Meeting of The American Physical Society The Propagation of Nonlinear Pressure Waves Through Regions of Non-Uniform Temperature NICHOLAS DIZINNO, GEORGE VRADIS, VOLKAN OTUGEN, Polytechnic University — A numerical study of wave propagation through gases with non-uniform temperature distributions will be presented. The aim of this study is to determine the impact of temperature gradients on highintensity pressure waves of various initial wave forms. Emphasis is paid to wave reflection and transmission. Ultimately, the performance of thermal barriers in attenuating nonlinear waves is evaluated. The concept of using regions of hot gas inside an ambient environment has potential in aeroacoustic applications, such as jet screech mitigation. This analysis considers the one-dimensional compressible unsteady Euler's equations with an ideal gas state equation. The domain is composed of two regions with uniform and equal gas properties separated by a third region with higher gas temperature (lower density). Pressure is uniform throughout the domain. We introduce various high-intensity wave forms into this medium. Our investigation studies how the shape and extent of the thermal zone affect transmission and reflection of the wave. This is done for a range of wave and thermal field parameters. A Fourier analysis will study the frequency content of the incident, transmitted and reflected waves. These results will help determine the effectiveness of using thermal barriers for nonlinear wave attenuation.


Cold climate areas that provide opportunities for the remote inspection of pipelines include the Barents Sea, the Russian Arctic, the Alaskan Chukchi Sea, the Beaufort Sea and the Canadian Arctic offshore. First, an analysis of several actual projects of contactless diagnostics using the magnetic tomography method of pipelines in Arctic conditions is done. Second, the Risk-Based Inspection methodology for Arctic offshore pipelines is discussed. It involves ensuring pipeline reliability on the basis of data on the technical condition of the metal in actual operating conditions. The magnetic tomography method allows not only to remotely identify areas of anomalies with metal defects, but also to register mechanical stress levels taking into account actual loads. This reduces the risk for the structure to come to the critical state in terms of exceeding local loads. Finally, magnetic tomography technology allows managing risks in cases of local corrosion, stress cracking or loss of stability of underwater pipelines in areas with free spanning. The qualitative indicators of the inspection include the probabilities of identifying, interpreting the degree of danger, missing a dangerous defect. The pipeline diagnostics report provides the parameters of reliability forecasting: the period of incident-free operation, safe working pressure, and pressure coefficient.

This paper presents a digital simulation concerning load rejection on a power system with a series capacitor compensated transmission line and saturated transformers. The simulation takes into account the nonlinearities of magnetization characteristic of the transformer. Influences of the compensation level, the amount of load to be rejected, the line loading and the asymmetrical operation on overvoltages are also investigated.


There is a burgeoning interest in 'process' or 'activity' addictions and compulsions, as opposed to ingestive addictions (such as drink, drugs and food). Co-dependency, sometimes called 'relationship addiction', is just one of these. How much of the phenomena reflects a self-preoccupied and psychologised culture is open to question and there is now considerable popular interest in codependency (books by Melody Beattie such as Co-dependent No More and John Bradshaw, Healing the Shame That Binds You have achieved record sales). Co-dependency (CODA) groups have spread across America and the UK since the mid 1980s.While advocates of the codependency concept strongly argue that it represents a real syndrome, and should be included in official psychiatric classifications (for example Cermac, 1986), others dispute whether the term is meaningful at all and that it lacks any real evidence. In this first article of the Addictions without substance series I steer a 'middle course', arguing that co-dependency concepts can be clinically helpful, while reserving a degree of scepticism about how much they can be brought together as a discrete medical syndrome. Like Rice (1996), I navigate a course between the advocates of co-dependency and its critics.


6G promises a plethora of opportunities but what are the challenges associated with its roll-out? Keysight Technologies' Sarah LaSelva talks to Neil Tyler


This paper aims to analyze a collection of documents found in the "Camina" section of the Medinaceli Duchal Archive, which holds a large amount of documents related to the Meneses family from Portugal, counts and marquises of Vila Real and also Governors of Ceuta. With the passing of time, the Meneses family had managed to gather a large estate in the Portuguese kingdom. However, and after the enthronement of the House of Braganca in the 17th century, the unfailing loyalty of the Meneses towards the Spanish monarchy provoked their punishment. As a compensation for their dire situation, the King of Spain adapted and castillianized the Meneses titles of nobility, transferring them onto the last surviving female member of this family.


Thirteen specimens of sealed concrete with additives were tested out of which nine were for creep of sealed concrete and four for shrinkage test,for a period of 700 days under controlled temperature condition.From the comparison results between experiments and model of ACI-209R,they coincide very well and the ACI-209R model can be used to predict shrinkage and creep of sealed concrete with additives.Based on regression analysis,modification on ACI-209R model has been formulated which will give more accurate prediction results.Besides,on the basis of observation on identical specimens with varied stress strength ratio,a function is generated which accounts effect of stress strength ratio on creep.


Today, it offers 120 places for heroin-supported treatment, with 2/3 of the patients being women, so as to ensure the correct gender balance in the treatment. The team is made up of around 30 employees. Heroin in liquid and oral form is the chief narcotic prescribed. The polyclinic is located in the centre of Zurich. The case study of Iris B. describes the long road to abstinence and shows that there are many intermediate targets to be met en route, including mental and physical stability and a suitable social environment. Mario K. is one of those patients who can stabilise their situation in life from time to time, providing they are constantly accompanied, but who repeatedly experience severe crisis phases. Over a prolonged period, the treatment is aimed at stabilising the patients' situation in life.


This study of Alumni Gym shows the integration of energy efficient systems into a building that will remain cosmetically the same from the exterior, but will express modern technologies from the interior. Using the LEED certification system as a guide, energy efficient systems were analyzed and assessed for their financial benefits to WPI with a focus on environmental safety. Among the areas covered in this study are: green roofs, air quality, HVAC, insulation, lighting, water usage, and windows.


In the study, we investigated the association of polymorphic locus CMA 1/B (G1903A) with indicators of oxygen transport system of the body. To determine the nucleotide substitutions in the gene CMA1/B, we used RFLP- analysis, PCR products were digested with the restriction enzyme BstXI. Analysis of the distribution of frequencies of alleles and genotypes CMA1/B showed statistically significant differences in the frequency of polymorphic variants of genotypes between athletes and controls. Athletes have predominant genotype A/A (0,52), and G/G (0,4), whereas in the control group, the most common genotype A/G (0,58). Using factor analysis, we revealed differences in the structure of the association between indicators of oxygen transport system depending on the genotype of the gene CMA. It was revealed the association of polymorphic gene variants with red blood parameters, hemodynamic and respiratory systems, as well as with physical endurance and tolerance to the muscular load. The closest connection between the studied traits detected at polymorphic variants CMA A/A. At this genotype physical endurance largely depends on the state of the circulatory system and the respiratory system functional reserves. It was also shown the correlation between adaptive capabilities of cardiovascular system and efficiency of the heart functioning with the level of motor activity. The interaction complex of the features that characterize the activities of the cardiorespiratory system, system, causes the formation of the final phenotype, which obviously explains the detected frequency distribution of different genotypes in athletes.


In mainland Portugal, conservation and promotion activities inside protected areas (PA) are mainly dedicated to biodiversity issues. In order to identify the value of geomorphology and landforms in these PA, as well as its recognition, some considerations are now discussed. A numeric analysis of terms like biology, geology, geomorphology, physical environment, natural heritage and resources, landscape and cultural subjects presented in the official documents that created the PA, reveal the larger importance of biodiversity over other subjects. Nevertheless, these documents include a significant number of mentions to the abiotic nature and to the landscape. The analysis of the PA dominant geomorphological environment indicates that PA are mainly associated with mountain environments (52 %), coastal environments (17 %), and fluvial environments (29 %). This simple assessment shows the intrinsic and essential value of geomorphology in the establishment of Portuguese PA, although not intentional. Another analysis estimates the relative importance of landform assets suggesting a major presence of residual and fluvial landforms over coastal, granite, glacial, tectonic, and karstic landforms. However, these results should not express the real heritage value of different landform assets because they do not consider important factors as rarity or accessibility. Despite the occurrence of significant geomorphological heritage outside PA, a major concentration of geomorphosites is seen inside PA due to the close relation between the most interesting geomorphological environments and the conception of PA. This fact suggests that geomorphological characteristics were in fact the main reason for the PA creation, in spite of the motives expressed in the legislation, mainly of biologically nature. These indications show that more attention should be given to geomorphology within nature protection strategies.


Hyoid bone fracture is usually due to strangulation, and, rarely, other forms of trauma. Its sequaelae are often immediate and distressing, and may be fatal. A prominent diagnostic sign is a palpable click. Concealed fractures can present confusing symptoms. Two cases of previously undiagnosed hyoid bone fracture are presented, one affecting the greater cornu, the other, a fragmented fracture of the body of the hyoid. Considerable odynophagia was the main presentation in both cases, for two years in the first, and seven months in the second. In the first case, the probable cause was forcible deglutition against pressure. Spastic tongue and respiratory distress were encountered in both cases. The second patient finally presented with stridor after seven months. Conclusion: Fracture of the hyoid bone can be missed during examination and may lead to spastic tongue and respiratory distress.


The advent of femtosecond lasers which can by used to control X-ray and electron sources promises the development of diffaction techniques for the determination of excited-state structures and time-resolved "movies" of molecular transformations [1, 2]. A recent electron gun design [3] offers 30fs, 0.1 pC pulses from 100 kV electrons with a spot size of 500 microns and 3nm coherence width. This gun is based on a photocathode, two magnetic lenses, and an RF cavity. In this paper we propose the use of this gun in a pump-probe arrangement, for gas diffraction in combination with a new method of molecular image reconstruction [4,5]. 1 shows the experimental arrangement. Gas-phase molecules are injected using a free-expansion nozzle at A, with rotational temperatures of a few degrees Kelvin. An Omega filter passes only those electrons which have not lost more than about one electron-volt energy while traversing the gas jet. CCD detectors with high-speed readout have recently become available, and an electron scintillator screen of corresponding will required. The laser is split to arrive first at the sample, where intermediate of the molecules are excited, then, after a delay, to the photocathode, to generate a pulse of electrons which generates a diffraction The repetition rate is synchronized to the detector. Many patterns may collected for each Each different delay provides a different of the final Since only a small fraction of molecules are excited, differences between patterns from dark and illuminated molecules must used. note:

RFID system is a contactless automatic identification system using small and low-cost RFID tag. It allows to recognize the information of tag via radio frequency attaching RFID tag to an object such as a material object, human or animal. Since RFID system has an advantage to recognize massive information simultaneously, it will be able to replace the bar-code system. For this RFID system to be widely spread, the problem of multiple tag identification, which a reader identifies a multiple number of tags in a very short time, has to be solved. So far, several anti- collision algorithms are developed. We present an RFID tag anti-collision protocol, called the query tree protocol with reversed IDs (QTR protocol). This protocol works by reversing the IDs of the tags and then applying the query tree (QT) protocol. And we present the performances of the QTR protocol by simulation. QTR protocol outperforms QT protocol if the tag IDs are consecutive integers.


If a colored plasma is produced in ultrarelativistic collisions of heavy nuclei, its presence can be inferred by observing that the $\ensuremath{\rho}$-meson peak in the mass spectrum of emitted dileptons disappears as their transverse energy increases.


1. Attenuated total reflectance (ATR) Attenuated total reflectance is commonly used for analysis of liquids and powders for which simple transmittance measurements are not possible. The method relies on a crystal with a high refractive index, which is in contact with the sample and serves as a waveguide for the IR radiation. The radiation beam is directed in such a way that it hits the crystal/sample interface several times, each time penetrating a few microns into the sample. Since the penetration depth is limited to a few microns, very good contact between the sample and the crystal must be ensured, which can be achieved by working with samples close to water saturation. However, the strong absorbance of water in the mid-infrared range as well as the absorbance of some soil constituents (e.g., calcium carbonate) interfere with some of the absorbance bands of interest. This has led to the development of several post-processing methods for analysis of the spectra. The FTIR-ATR technique has been successfully applied to soil classification as well as to determination of nitrate concentration [1, 6-8, 10]. Furthermore, Shaviv et al. [12] demonstrated the possibility of using fiber optics as an ATR devise for direct determination of nitrate concentration in soil extracts. Recently, Du et al. [5] showed that it is possible to differentiate between 14N and 15N in such spectra, which opens very promising opportunities for developing FTIR-ATR based methods for investigating nitrogen transformation in soils by tracing changes in N-isotopic species.


Much has been written concerning filtration experiments with various types of artificial filters such as the Berkefeld, Chamberlain and collodion membranes. Recently a new type of filter has come upon the market, the Seitz-Werke filter, and for certain types of work is apparently quite efficient. The efficiency of all these types of artificial filters, as far as the mere removal of bacteria is concerned, is beyond question. It is only when investigators attempt to draw fine conclusions from filtration experiments employing such filters that their value is questioned. A substance, for example, which is filterable through a Berkefeld Type N or W filter in the hands of one investigator may not be filterable when presumably the same type of filter in every respect is employed by another. Such results are very confusing and often discouraging. This has been particularly true in the field of filterable viruses and indeed, there are many viruses so classified at the present time upon the sole basis that they have, in the hands of some workers, been able to pass through one of these artificial filters. In the first place it is well known that filters of this type, even when new and unused, though prepared by standard methods, still vary one from the other. No two are precisely the same. Again the amount of pressure employed by different workers against these filters is never the same and further in many instances the filter is not controlled. The time element of filtration is known to be important and there are always the variations in individual technique which add to the general unreliability of results. These criticisms are well known to all laboratory workers and as a result we have come to regard filtrability through such filters in the same sense as diffusibility, as only a relative concept.


This paper belongs to a research line we are performing on hydrosoluble vitamins. In this work we have analysed vitamin C content in drumhead cabbage and cauliflower as well as its decrese when these vegetables are submitted to pressure cooking or microware cooking. The analytical technique employed has been spectrofluorimetry.


The purpose of this study was to examine statewide motorcycle crash data from the state of Ohio to identify those factors most strongly associated with the level of injury sustained by motorcyclists involved in crashes. The year 2009 marked the first time since 1997 that Ohio experienced fewer motorcycle fatalities than in the previous year; this result was consistent with national trends over this same period. Since anecdotal evidence suggested that much of this result was due to decreases in motorcycle travel, an investigation of rider, crash, and environmental factors that influenced injury severity was an important step toward sustaining this reduction. The effects of such factors in various types of motorcycle crashes were compared. Multinomial logit models were developed for single-vehicle and multivehicle motorcycle crashes at both intersection and nonintersection locations. The results showed that the impacts of relevant crash factors varied by crash type and location and that severe injuries were more likely when high speed or alcohol was involved. Collisions with fixed objects and high-impact crashes, such as angle and head-on collisions, also produced dramatic increases in injury severity. Helmet use continued to provide the most promising means of reducing severe and fatal injuries in all types of crashes. Helmet use was found to reduce the likelihood of injury by 34.4% in single-vehicle crashes and between 12.4% and 14.1% in multivehicle crashes.


In this work we study the correlation function of the ground state of a two-dimensional fully frustrated Ising model as well as spin glass. The Pfaffian method is used to calculate free energy and entropy as well as the correlation function. We estimate the exponent of spin correlation function for the fully frustrated model and spin glass. In this paper an overview of the latest results on the spin correlation function is presented.


Background C-reactive protein (CRP) is an acute phase reactant released in response to inflammation or tissue injury. Inflammation is one of the pathogenic factors related to transition from acute postsurgical pain (APSP) to chronic postsurgical pain (CPSP). Although several risk factors are reportedly associated with CPSP, the effects of CRP levels on CPSP have not been examined. Objectives The present study investigated the relationship between perioperative risk factors, including CRP levels on postoperative day one and CPSP, in patients undergoing mastectomy. Methods Preoperative anxiety and depression levels were evaluated in female patients undergoing mastectomy under general anesthesia, with or without peripheral nerve block. Patients with chronic preoperative pain and/or preoperative breast pain were excluded. The intensity of postoperative pain was prospectively examined one and six days, and three and twelve months after surgery using a numerical rating scale (NRS). Results The current researchers conducted univariate and multivariate linear regression analyses to explore risk factors for CPSP in 36 patients. Patient demographics, preoperative psychological states, and anesthetic managements showed no relationship with CPSP. On the other hand, pain intensity of APSP and CRP levels on postoperative day one was significantly associated with the pain intensity of CPSP. Conclusions Postoperative CRP level is likely to be associated with the development of CPSP after mastectomy.

A highly efficient strategy for synthesizing the first biocompatible polyesters with AIE characteristics has been established via immortal ring-opening polymerizations of cyclic esters bearing nonluminophores. In the process, the large excess hydroxyl-modified AIE active compound, acting as the chain transfer agent, attaches to the active rare-earth metal catalyst via the rapid-reversible exchange reaction to initiate the polymerization. Thus, more polyester chains appear to grow from one active metal species, and the AIE fragments are incorporated into the polymer chains at specific sites, in situ. The resultant polyesters have linear, block, or star-shaped microstructures mimicking those of the modified AIE compounds. The polymerization solutions can be directly fabricated to large-area thin solid films. The obtained PLA, for instance, emits fluorescence in water/THF mixtures owing to aggregation, the intensity of which is 2850-fold stronger than that in THF solution. This strategy avoids complicated pr...


This study proposes a three-stage process for Social Customer Relationship Management (SCRM) engagement framework by Australian private sector companies. The mixed methods research design were employed using a sample of 597 Australian companies from surveys, incorporating semistructured interviews with senior IT and marketing managers from fourteen different companies. Descriptive statistics and thematic analysis were used to analyse data and provide the requirements at the initial stage of SCR Madoption. The survey and interview findings reveal that level of SCRM adopted by Australian companies is relatively superficial and ad hoc in the absence of a formal integrated SCRM strategy and policy framework. Additionally, the integration of both findings have further extended into the development of proposed practical framework to illustrate how SCR Mshould be carried out from a company's strategic perspective. The proposed framework was describes by applying the principles of Resource-Based View (RBV) theory in helping companies make a decision about such engagement.


As this article is being written, unemployment in the United States is nine percent and rising higher, factory production has fallen 9.6 percent since July 1981; and the leading economic indicators are still pointing downward. Figures alone do not convey the weakness of the American economy. Omitted from these figures is the human suffering caused by the unemployment, the lagging productivity of American industry', the de facto bankruptcy of the savings and loan industry, and the imbalance in the debt-to-equity ratio of corporations.


Background: Agr systems, is responsible for control and coordination in production of virulence factors, exotoxins secretory and hemolysins in Staphylococcus aureus. The aim of this study was to determine and identify the frequency of agr genes in susceptible and methicillin-resistant Staphylococcus aureus strains in clinical samples and carriers employed in remedial centers. Materials and Methods: This descriptive study was done among a total of 200 strains of Staphylococcus aureus isolated from clinical samples and healthy carriers in Hamadan. Antibiotic susceptibility pattern of all isolates was determined by disk diffusion methods. After DNA extraction, the presence of mecA and agr genes was investigated using PCR. SPSS software package version 20 was used to perform statistical tests. Results: All 200 Staphylococcus aureus strains were susceprible to vancomycin. The prevalence of mecA was 50%. The PCR results showed that agrA was the most perevalent gene followed by the agrC in all isotated Staphylococcus aureus strains. None of the isolates harbored the agrB and agrD gene. Conclusion: Pathogenesis of Staphylococcus is dependent on some proteins other superficial or excreted which under controlling of agr system. In the present study, the feequency of agrA gene in the methicillin-resistant strains, methicillin-sensitive strains isolated from clinical samples and carriers employed in remedial centers was higher than the other agr types. Therefore, presumably, agrA gene plays an important role Staphylococcal infections.


The objective of this work was to study the effect of two technical modifications (supplemented with sponge materials (ES) and provided with a filter system (FIL))in continuous-culture fermenters on the microbial populations and ruminal fermentation parameters over the sampling period. Six fermenters fed a 50:50 alfalfa hay: concentrate diet, inoculated with rumen liquor from sheep fed the same diet, were used in two incubation runs of 14 days each. On days 10 and 14, samples were taken for analysis of fermentation parameters (volatile fatty acids, ammonia-N and lactate) and microbial populations. None of the technical modification affected (P>0.05) concentrations of bacterial DNA and the relative abundance of fungi and archaea, but protozoal DNA concentrations were higher (P>0.05) in ES and FIL fermenters than in the control ones. However, values of protozoal DNA were about 50 times lower than in the rumen fluid used as inoculum for the ermenters. The tested technical modifications did not affect (P>0.05) any fermentation parameter, and there were no differences in fermentation parameters between days 10 and 14, with the exception of lactate production which was higher (P=0.009) on day 14 than on day 10. In conclusion, the technical modifications tested maintained protozoa in continuous culture fermenters without any effect on fermentation parameters and other microbial populations, but protozoa concentrations were still lower than those in the rumen.


More than a decade after the beginning of the moviment towards Psychiatric Reform in Brazil, new forms of assistance for the so-called "mad", such as CAPS, NAPS, hospital day-care, have been set up. Thus, the current moviment appears to be one of reflection and the evaluation of these practices with a view to pin-pointing further developmental measures.


When I assumed the position of Honors Program Director along with my other responsibilities, I was handed the Honors Program Review from the previous five years. Nestled among the goals and objectives--alongside of recruiting, marketing and identifying faculty to teach honors courses--was the most pressing problem: serious declining enrollment. Students were being recruited for the honors program by the department of admissions, but only a very small number were continuing into their junior and senior years. With this problem of disappearing numbers came the possibility of a disappearing honors program. Apparently most of these students were dropping out of the honors program during either the second semester of their freshman year or the first semester of their sophomore year. Once they achieved junior status, the attrition rate dropped and the prospect of completing the program became slightly more promising. Still, only a handful of students were leaving the university with "Honors Program Completed" prominently displayed on their transcripts. The crux of my problem became evident: if I hoped to retain the position of Honors Program Director, the administration "strongly advised" that I find a way to improve the completion rate of students in the program. The methodology was left up to me. I needed to discover more effective strategies to recruit students and keep them motivated enough to remain in the program, but in doing so I was not to cripple the integrity of the program. As Yul Brynner would say, "Ah ... a puzzlement!" An honors program must serve the needs of existing students as well as those it attempts to recruit. An effective program must carefully examine such issues as student ability, availability of honors courses, availability of qualified and motivated faculty who are willing to teach honors courses, always-present budget concerns, and, lastly, data on those students who complete the program. The last criterion, the completion rate, is the primary concern here. As universities go, we are a small institution composed of approximately 3400 undergraduate students. Our honors program, like many programs across the country, suffers from some of the same afflictions that plague similar institutions. Highly regarded by both our university president and provost and acknowledged in the university mission statement's charge to "... emphasize the importance of the honors program to advance the academic quality of the university and give increased attention to the promotion of this program," we still lack the stability of permanent faculty assigned to teach honors courses each year. Hence, our program must cross its academic fingers each semester that it will be able to provide sufficient faculty support to cover the courses listed in our program. Faculty on load cannot often be compensated to teach an honors course on overload. In addition, some majors--often in the most challenging academic programs that would make them ideal as honors program students--were finding it difficult if not impossible to complete both their major and the requirements in the honors program successfully within four years due to either certification or professional stipulations within those majors. The obvious choice for these students was to forego enrollment in the honors program and finish their major regardless of how attractive enrolling in the honors program might have been to them. An honors program cannot be analogous to an assembly line. The requirements to complete an honors program should not be so restrictive as to allow only an elitist few to finish or so generalized that any student can enroll simply by asking to join. A program director who does not consider the impact of the number of students who actually finish the program is not being realistic when administrative decisions are made about which programs will or will not be budgeted for the following year on the basis of enrollment. At the same time, intellectual and curricular concerns of honors students are paramount in an honors program. …


We apply the method of innnitesimal unitary transformations recently introduced by Wegner 1] to the Anderson single impurity model. It is demonstrated that this method provides a good approximation scheme for all values of the on-site interaction U, it becomes exact for U = 0. We are able to treat an arbitrary density of states, the only restriction being that the hybridization should not be the largest parameter in the system. Our approach constitutes a consistent framework to derive various results usually obtained by either perturbative renormalization in an expansion in the hybridization ?, Anderson's \poor man's" scaling approach or the Schrieeer{Woll unitary transformation. In contrast to the Schrieeer{Woll result we nd the correct high{energy cutoo and avoid singularities in the induced couplings. An important characteristic of our method as compared to the \poor man's" scaling approach is that we continuously decouple modes from the impurity that have a large energy diierence from the impurity orbital energies. In the usual scaling approach this criterion is provided by the energy diierence from the Fermi surface.


Using semi-algebraic description of task level configuration space (TLCS) and calculus of variations, trajectory plans avoiding the otherwise invisible, TLCS obstacles, arising from the kinematic constraints due to the joint limits are synthesized. This computationally tractable trajectory planning consists of shortest and smooth geometric path planning satisfying kinematic constraints, and event-based motion planning. As opposed to the conventional algorithmic approaches to the path planning, this appealing closed form solution of the path and motion planning, and real time control is easily applicable to computer integrated manufacturing applications. The validity of this synthesis along with a real time control is demonstrated through simulation and experiment on a PUMA 560 manipulator.<<ETX>>


The Fourier Continuation (FC) method[1] provides a smooth, periodic continuation to a non-smooth function. This allows for a Fourier series to be used in the solution of Partial Differential Equations where periodicity is not applicable. Furthermore this provides a smooth continuous interpolation of the function throughout the domain. In this investigation the accuracy of the Fourier series and it's derivative was compared to the analytical solution. Introduction

The conceptual connections between aspects of critical thinking described by the Reflective Judgment Model, a theory of adult intellectual development, and a larger set of psychological principles derived from constructivist theories of learning are highlighted. In spite of parallels between these conceptual schemes, as well as the practical implications each has for secondary and higher education, there is still a dearth of literature dealing specifically with how to translate such theories into sound teaching strategies involving young adults. This limitation is addressed by describing introductory activities for units in human development and motivation in an undergraduate educational psychology course. The activities are evaluated using criteria associated with constructivist learning theory in general and with the Reflective Judgment Model in particular. Finally, it is argued that elements of the activities are generalizable to other levels, such as high school and graduate school, to other courses in teacher education, and to other domains of knowledge such as the humanities and physical sciences. Four appendixes present materials used as topics in the classes. (Contains 1 table and 27 references.)

Simple, rapid and highly sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) assay method was developed for the determination of Carisoprodol in human plasma. Carisoprodol methyl D3 was used as an internal standard (IS). The method employed 250μl of human plasma for sample processing by a simple Liquid Liquid Extraction (LLE) technique. The processed samples were chromatographer on a Phenyl column by using a mixture of 10mM Ammonium format-Acetonitrile (15: 85, v/v) as the mobile phase at a flow rate of 1.2ml/min. The calibration curve obtained was linear over the concentration range of 25-3000ng/ml with r2 > 0.99. Method validation was performed as per the FDA guidelines and the results met the acceptance criteria. The Selected Ion Monitoring (SIM) mode was used for quantification of ion transitions at m/z 261.3/176.1 and 264.4/179.2 for the analyte and the IS respectively. A run time of 2.0 min was used which made it possible to analyze more than 400 plasma samples per day, thus increasing the productivity.

The study was carried out to investigate the effect produced by water-soluble form of quercetin (corvitin) on the indices of the development of oxidative-nitrosative stress in periodontal soft tissues of rats subjected to systemic inflammatory response. This condition was simulated by using two models: one was induced by the Salmonella typhi lipopolysaccharide (LPS) administration (in a dose of 0.4 μg / kg of body wt three times through the 1st week and once a week for the next 7 weeks), as well as on the 14th day after a moderate craniocerebral injury (CCI). Applying corvitin in a dose of 500 μg / kg (10 μg / kg recalculated as quercetin) every third day starting from the 30th day of the experiment with the use of pyrogenalum reduced the production of superoxide anion radical (.О) by NADPH-dependent electron transport chains (endoplasmic reticulum and NO-synthase) by 18.1%, but did not considerably affect the mitochondrial chain. .О production by leukocyte NADPH-oxidase was by 16.7% lower. The total NO synthase (NOS) activity in periodontal tissues decreased by 40.6%, and the content of peroxynitrite ions was inferior to the relevant result of the group received pyrogenalum by 13.9%. Administration of corvitin in a dose of 500 mg/kg for 7 days after CCI modeling reduced the (.О) production by NADPH-dependent chains by 20.9%, and by mitochondria by 31.7% on the 14th day of post-traumatic period. .О production by leukocyte NADPH-oxidase was by 35.8% lower. NOS activity in periodontal tissues decreased by 45.8%, the content of peroxynitrite ions was inferior to the relevant value in the group with modeled CCI by 25.7%. This suggests the conclusion that applying water-soluble form of quercetin in conditions of systemic inflammatory response limits the signs of oxidative-nitrosative stress in periodontal soft tissues of rats.


The purpose of this paper is to explore citizens' willingness to invest in photovoltaics.,To meet the aim of the research, a questionnaire survey was conducted in the island of Evia in Greece using the method of random stratified sampling. A total of 366 responses were analyzed using both descriptive and inductive statistics methods, such as principal components analysis, K-means cluster analysis, discriminant analysis and binary logistic regression.,The research results indicate that 73per cent of the respondents would invest in renewable energy sources, whereas 55per cent of them would specifically invest in photovoltaics. Regarding their views on photovoltaics, three components were extracted; photovoltaics positive effects, facilitations for investments in photovoltaics and photovoltaics' performance. Area of residence, annual income and the above-mentioned three components of views on photovoltaics were found to be statistically significant for the dichotomous variable of willingness to invest in photovoltaics. Among the examined variables, photovoltaics performance found to contribute the most in increasing respondents' willingness to invest in photovoltaics.,The study filled the literature gap concerning citizens' willingness to invest in photovoltaics in Greece. Furthermore, the research results made feasible to understand the factors that can lead in an investment decision for photovoltaics.


The PhD dissertation studies meteorological and economic hazard under different angles and mostly in developing countries. It is composed of three independent chapters analyzing different situations dealing with meteorological and climatic or economic hazard correlation. It estimates the potential of the studied regions for implementing an insurance scheme for the risk. Indeed, this thesis studies risks very likely to be highly correlated: whether this is for the meteorological or climatic hazard, or the price volatility risk, neighbored cities or even countries are exposed to the same risk simultaneously. This essential aspect jeopardizes risk mutualization, a key parameter of the economic insurance model. Through the three chapters of this thesis, we study the benefits linked to the mutualization of a priori correlated risks. The first chapter deals with maize price correlation in Tanzania. Using a Copula-GARCH model, we model the dependence among the 20 main markets of the country and assess if the mean maize price is smoothed by aggregating the markets. Hence, we see whether markets integration allows an efficient risk mutualization against the risk of price volatility. The second chapter deals with tropical storms risk in the South Pacific islands and their impact on infrastructures. This paper proposes an artificial tropical cyclones modeling in the region studied as well as the probability distribution of the cyclone's occurrence and strength. This enables us accounting for the current climate for modeling costs. With data on infrastructures, we calculate the cost due to tropical storms, including for very low probability extreme events. The third chapter proposes an extension for a statistical emulator of crop yields depending climatic variables. We model the marginal impact of an increase of temperature, precipitations and CO2 concentration by running a statistical estimation on crop models rather than historical data. It allows accounting for extreme effects caused by meteorological data values not observed so far. The model robustness is assessed, among others, with copulas to compare the spatial dependence between the model and our statistical emulator and check that our estimation captures the geographic dependence.


Surface treatment of cattail, a lignocellulosic renewable fiber, was investigated to determine the conditions that would reduce moisture absorption while maximizing the properties of cattail fiber‐reinforced unsaturated polyester composites. Surface modification of cattail fiber was studied by treating them with 2.5, 5, and 10% of 1,6‐diisocyanatohexane (DIH) and 2‐hydroxyethyl acrylate (HEA) for three different immersion times (10, 20, and 30 min). DIH‐HEA treated fibers were preformed into a non‐woven mat and impregnated with unsaturated polyester resin to manufacture composite. The existence of covalent bonds on the treated fibers via NH and CN groups was confirmed by FTIR spectroscopy. The 10% DIH‐HEA resulted in the best results; while the mean diameter of the treated fiber decreased by ~37%, the modulus and the strength of it increased by ~267 and ~151%, respectively. Equilibrium moisture regain of the treated fibers and their composites decreased by ~43% and ~40%, respectively. The tensile modulus of the composites increased by ~171%. Enhancement in tensile strength is observed but could not be quantified due to the difference in Vf and scatter in the data. SEM examination confirmed the enhancement in fiber–matrix bonding due to surface treatment.


: Structured-light 3D reconstruction techniques are employed in a wide range of applications for industrial inspection. In particular, some tasks require micrometric precision for the identification of microscopic surface irregularities. We propose a novel calibration technique for structured-light systems adopting telecentric lenses for both camera and projector. The device exploits a fixed light pattern (striped-based) to perform accurate microscopic surface reconstruction and measurements. Our method employs a sphere with a known radius as calibration target and takes advantage of the orthographic projection model of the telecentric lenses to recover the bundle of planes originated by the projector. Once the sheaf of parallel planes is properly described in the camera reference frame, the triangulation of the surface's object hit by the light stripes is immediate. Moreover, we tested our technique in a real-world scenario for industrial surface inspection by implementing a complete pipeline to recover the intersections between the projected planes and the surface. Experimental analysis shows the robustness of the proposed approach against synthetic and real-world test data.


Today, during service delivery, providers allocate their delivery resources such that their own delivery-dependent costs are minimal. However, during service delivery, costs arise not only for the provider, but for the customer, too. In industrial maintenance, for example, those costs arise—depending on service delivery—due to longer equipment unavailability. The concept of system-oriented service delivery aims at minimizing the total (customer and provider) delivery-dependent costs within the service system and promises a Pareto improvement over today's practice. Hence, added value is created. However, so far, we have no understanding of the magnitude of and factors favoring high added value through system-oriented service delivery. Consequently, this work aims at filling this gap and widening knowledge on the added value through system-oriented service delivery. We present a simulation study to elaborate on the added value in dependency of the customer base constellation in an industrial maintenance illustrative scenario.


SUMMARY In this trial, we assessed the effects of 2 different ages of breeders and of 2 periods of fasting posthatching on the performance of broilers up to 42 d of age. Male broilers from breeders of different ages (30 and 60 wk) were subjected to an experimental design with 4 treatments: 1) T1, chicks not subjected to fasting, from 30-wk-old breeders; 2) T2, chicks not subjected to fasting, from 60-wk-old breeders; 3) T3, chicks subjected to a 12-h fast, from 30-wk-old breeders; and 4) T4, chicks subjected to a 12-h fast, from 60-wk-old breeders. At the end of the trial, feed intake was greater for the chicks from older breeders. Fasting had a negative influence on feed intake in the period from 0 to 10 d of age. The birds from older breeders had a greater BW gain from 21 to 35 d of age when they were not subjected to a fasting period, but when birds were subjected to a fasting period, no differences between broiler breeder ages were observed on BW gain. Fasting did not exert a significant effect on the BW of the birds. Feed conversion was not influenced by the age of the breeders or by fasting.


Objectives This study investigated the effects of marital intimacy and gender equality consciousness on job satisfaction among married working women, and examines the mediating effect of work-family conflict in these influence relationships. Methods As for the research method, a quantitative cross-sectional survey was conducted by selecting 2,083 married and working women as the study subjects in the Women and Family Panel Survey 2018 (9,602 women). For data analysis, SPSS 25 program was used. In order to verify the mediating effect of work-family conflict, the three-step analysis method of Baron & Kenny (1986) was selected. Results A summary of the results of this study is as follows. First, married working women's marital intimacy was found to have a statistically significant (+) effect on job satisfaction (p<.01). Second, the gender equality consciousness of married working women was found to have a statistically significant positive (+) effect on job satisfaction (p<.05). In addition, marital intimacy was found to have a positive effect on reducing work-family conflict, which showed a statistically significant result (p<.01). Third, marital intimacy alleviated work-family conflict, and alleviated work-family conflict had a positive effect on improving work satisfaction at work (p<.001), and gender equality awareness also reduced work-family conflict. It was confirmed that work-family conflict that was alleviated and alleviated increased work satisfaction (p<.001). Conclusions Based on this, in order to improve job satisfaction of married working women, it will be necessary to intervene in social welfare practices, such as developing programs and building infrastructure to increase marital intimacy and awareness of gender equality. In addition, the government, local governments, and local communities should connect and expand a family-friendly system that can reduce work-family conflict. Therefore, this study intends to provide the implications and basic data for improving job satisfaction among married working women.


Case-law in Egypt, though not binding on subsequent courts, for Egypt being Civil Law country, helps interpreting new texts of law, when tested in real-life situations. In this line, the commentator traces, the application of the concept of 'impartiality' of arbitrator in contrast with his 'independence', regulated under the Egyptian Arbitration Act 27 of 1994 (Art. 16(3)); this is under a recent decision, rendered by the Cairo Economic Court, on April 12, 2011 (6th Appeal Circuit, Case 98/2), in an international arbitration case, taking place under the auspices of Cairo Regional Center for International Commercial Arbitration (CRCICA) Rules 2007.The commentator supports the conclusion of the decision, expected to be a leading authority on Egyptian arbitration law, when it stressed on the importance of impartiality and independence of the arbitrator, and its consequential effect on this arbitrator's continuous responsibility to disclose any circumstance that may raise serious doubt on his satisfaction of such qualities. In this case the court declared the arbitrator missing such qualities, and therefore accepted challenging his jurisdiction, due to the fact that he was appointed in a second case relative to the same first contractual dispute, in a different personal scope; such circumstance was not revealed to either cases' parties or panels. The commentator however criticizes the court's decision, for its mixture between the concepts of 'impartiality' and 'independence', since the circumstance, in the dispute, relates to the 'state of mind' of the arbitrator, leading to 'impartiality', therefore reference to 'independence' was neither needed nor correct. Also, under the case in dispute, the arbitrator, by not disclosing the fact of his joint appointment, fails to adhere to his duty of disclosure. However, since the case was that of his 'impartiality' in the first case, his unqualified acceptance of appointment in the second case was irrelevant for the first case and which was the substance of the court decision. According to the commentator, courts' focus should have been on the arbitrator's failure to report his second appointment to the parties and Panel of the first case.The commentator also made a plea for the activation of the arbitrator challenging rules that could be available under the rules of arbitration centers in Egypt, as is the case of CRCICA, especially after its amendments in 2011, in attenuation of the restriction established by the Egyptian Supreme Constitutional Court of November 6, 1999 and in application of Egyptian Arbitration Act (Articles 6 and 25), otherwise arbitration industry in Egypt will lag behind modern international arbitration law and practice; benchmarking was made with the recent UNCITRAL Arbitration Rules 2010 and French arbitration Decree 2011.


Suppose that a circular fire spreads in the plane at unit speed. A single fire fighter can build a barrier at speed [Formula: see text]. How large must [Formula: see text] be to ensure that the fire can be contained, and how should the fire fighter proceed? We contribute two results. First, we analyze the natural curve [Formula: see text] that develops when the fighter keeps building, at speed [Formula: see text], a barrier along the boundary of the expanding fire. We prove that the behavior of this spiralling curve is governed by a complex function [Formula: see text], where [Formula: see text] and [Formula: see text] are real functions of [Formula: see text]. For [Formula: see text] all zeroes are complex conjugate pairs. If [Formula: see text] denotes the complex argument of the conjugate pair nearest to the origin then, by residue calculus, the fire fighter needs [Formula: see text] rounds before the fire is contained. As [Formula: see text] decreases towards [Formula: see text] these two zeroes merge into a real one, so that argument [Formula: see text] goes to 0. Thus, curve [Formula: see text] does not contain the fire if the fighter moves at speed [Formula: see text]. (That speed [Formula: see text] is sufficient for containing the fire has been proposed before by Bressan et al. [6], who constructed a sequence of logarithmic spiral segments that stay strictly away from the fire.) Second, we show that for any curve that visits the four coordinate half-axes in cyclic order, and in increasing distances from the origin the fire can not be contained if the speed [Formula: see text] is less than 1.618…, the golden ratio.

Traditional surgical repair and endovascular repair (EVAR) are the treatment options for abdominal aortic aneurysm repair. EVAR as less invasive becomes a significant and widely accepted way of treatment aortic aneurysms with expanding number of procedures. This technique has a lover short‑term mortality and a shorter hospital stay but is not free from complications. The most common complication after EVAR are endoleaks. For the first time summarised and assessed in 1997. Although it is often asymptomatic but may cause aneurysm expanding and rupture. Endoleak is defined as persistent blood flow into the aneurysm sac. It can be revealed intra‑operatively or during the follow up – CT; arteriography, angio‑MRI enables endoleak diagnosis. Usage of duplex sonography is questionable. In this mini‑review we summarise endolek diagnostic, classification and treatment options.


As the data of the State Fiscal Service evidence, one of the main reasons for the application of penalties to agricultural enterprises is the use of land plots for which the right to lease has not been registered and incorrect (incomplete) introduction of data on the composition of land into tax reports. On the basis of the conducted research it was established that in the majority of agricultural enterprises the internal control of the use of land resources is imperfect and does not cope with its tasks or is generally absent. Therefore, the purpose of the article is to develop proposals for improvement the organization and methods of internal control of the land resources, which are used by entities of agrarian business. Comparison method, method of statistical analysis have been used in the analysis of the dynamics of changes in the number of agricultural enterprises, simulation method has been used in the in the process of developing proposals for improvement the methods of internal control. The organizational bases of internal control were disclosed in accordance with the requirements of the current legislation. The algorithm of the internal control of land resources which received on the use rights was developed. This algorithm maximally takes into account all features of the controlling object and provides for legal control. The methods of internal control presented in the article covers all economic operations related to land resources which received on the use rights: receipt and return from use; rent calculations (payment for use); formation and use of the fund for their restoration; implementation of capital improvements of land plots.


OBJECTIVE
The purpose of this study is to determine a concentration of iodinated contrast media in saline and 5% dextrose in water (D5W) for organ hydrodissection, a technique used to physically separate and protect tissues adjacent to thermal ablations.

MATERIALS AND METHODS
A total of 28 samples were prepared from 1:1000-1:1 iohexol or iothalamate meglumine contrast media in either normal saline or D5W. Samples alone or juxtaposed with a homogeneous liver-mimicking phantom were imaged by CT using 80-120 kVp and 10-300 mAs. Mean CT numbers and noise were measured from the fluid, background air, phantom adjacent to the fluid, and phantom distant from the fluid. Visibility was determined from the contrast-to-noise ratio between the fluid and phantom, whereas streaking artifact was quantified by relative noise in the phantom. Measures were individually fit using multiple linear regression to determine an optimal contrast-to-fluid ratio for increased visualization without streaking. Contrast media- and blood-doped saline and D5W were also tested to determine whether such doping altered their electrical conductivity.

RESULTS
Iohexol concentration most influenced CT number; volumetric ratios of 1:1000-1:1 produced 20 HU to over 3000 HU. CT numbers were weakly dependent on x-ray tube voltage, whereas contrast-to-noise ratio and streaking artifacts were somewhat dependent on tube output. An optimal ratio of iohexol in fluid was determined to be 1:50. There was no significant difference between the electrical impedances of doped and pure saline or D5W (p > 0.5, all cases).

CONCLUSION
A 1:50 ratio of iohexol in saline or D5W provides an optimal combination of increased visibility on CT without streaking artifacts.


© National Wellbeing Service Ltd 2018 • www.nationalwellbeingservice.com/journals 1 of 11 Abstract Gratitude journals have been used frequently as forms of intervention and indicate a positive effect on wellbeing. The present study explored the potential of gratitude journal apps and appreciated design features. It is empirically based on prior research and theoretically related to experience design, the Fogg Behaviour Model and domestication theory. A mixed methods design was applied that consisted of an online experiment as well as a focus group. The online experiment was conducted over two weeks with participants being randomly split into two groups. During week one, one group used a gratitude journal app whilst the other group used a traditional gratitude journal. For week two, these gratitude activities were swapped. Wellbeing was assessed at three points of measurement. Additionally, experience and preference of app versus traditional was evaluated as well as appreciated design features. To further explore the design features a focus group was assembled. 15 participants completed the online experiment, while 22 people participated in the focus group. Results show a significant increase in wellbeing from baseline to second point of measurement for the participants having used the app for one week. Overall, the experience with the gratitude exercise was positive with a slight preference towards the app. Appreciated features include the possibilities to personalise the design, to add pictures or voice memos and to have push notifications. The focus group further revealed that simultaneous wellbeing tracking, data protection and proposed sharing of entries would be much appreciated. The findings are embedded in theory and provide a basis for designing a user friendly gratitude journal app.


The antimicrobial effectiveness of three soft contact lens disinfection solutions widely available in Nigeria was evaluated against nine bacteria (Staphybcoccus aureus, Pseudomonas aeruginosa, Staphylococcus spp, Bacillus spp, Serratia spp, Proteus spp, Aeromonas spp, Micrococcus spp and Enterococcus spp) isolated from patients' lenses, eye swabs, lens cases and storage solutions. The disinfectants included hydrogen peroxide (Oxysept, Allergan), tris (2‐hydroxyethyl) tallow ammonium chloride thimerosal (Hydrocare, Pilkington Barnes Hind) and polyaminopropyl biguanide‐Dymed (#ReNu, Bausch & Lomb). The study demonstrated that all three disinfectants are capable of controlling microbial contaminations if used many months before expiration at regular concentration. Although disinfectants showed increased bacteriocidal activities with a prolonged exposure to the disinfectants, their efficacies declined rapidly when used one month prior to expiration.


Aspartyl aminopeptidase from Aspergillus oryzae has high substrate specificity, degrading only amino-terminal acidic amino acids from peptides, and may be suitable for processing physiological peptides. However, little is known about the biochemical properties of this enzyme and its efficient production in A. oryzae. The gene encoding aspartyl aminopeptidase was overexpressed under a takaamylase gene promoter, with His-tag linker in A. oryzae, during cultivation in a cobalt-containing medium. The enzyme was extracted from mycelia and purified with immobilized nickel ion absorption chromatography using a buffer containing cobalt ion and imidazole. The active fraction was further purified with gel filtration chromatography. The resultant, electrophoretically pure enzyme displayed a molecular mass of 520 kDa. This enzyme displayed high affinity to peptide substrate rather than synthetic substrates. Thus, recombinant A. oryzae aspartyl aminopeptidase was purified to homogeneity with an increased specific activity, when cultivated in a cobalt ion-rich medium. Moreover, the use of suitable metal ions in microbial cultivation and purification processes may help increase specific activity of other metalloproteases and their functional analysis. 3Aodap1 (AO090005001447 ) 1. aminopeptidase I zinc metalloprotease (M18) 2. Its deduced amino acid sequence is 52 % identical to yhr113w of Saccharomyces cerevisiae, whose enzymatic activity was reported. 3. The gene yhr113w encodes aspartyl aminopeptidase (DAP, acidic amino acid-specific aminopeptidase) 4. The existence of DAP was reported for yeast and mammals. 5. This gene is expressed in A. oryzae (EST data).


This study purports to determine the predictors of migrant workers' cultural adaptation in South Korea. In the main, we examined the extent to which the level of inter-/intracultural socializing, exposure to local/native media, and host culture receptivity affect the level of cultural adaptation in cognitive, affective, behavioral domains. Potential impacts of demographic factors (e.g., age, sex, ethnicity, marital status, living alone vs. with family, education level, residency in years, perceived cultural similarity) were also explored. To find answers to the research questions, a total of 634 migrant workers from 37 different nations were reached using a snowball sampling. Surveys were collected in 12 districts of Seoul, the capital of South Korea, and 21 adjacent metropolitan areas. Results indicate that intercultural interaction with host people and media exposure to local contents tend to help improve their knowledge about South Korea (e.g., language, culture). With all else equal, migrant workers treated kindly by Koreans at the workplace and in service sectors, and those living with family, compared to those who live alone, tended to enjoy a greater satisfaction with work and life in South Korea and were more willing to stay. Practical implications for Korean policymakers include encouraging competent migrant workers to move together with the family, making administrative efforts to further simplify the documentation process, and initiating public campaigns to raise host culture receptivity among Korean citizens.


UNIX is one of the most widely used operating systems on current workstations. However, UNIX was originally designed as a multitasking and time-sharing system with little concern for supporting real-time applications. Recent versions of UNIX have incorporated real-time features and the designers of these systems claim to provide better response times than the standard UNIX kernel. In order to assess the benefits of these new features and verify these claims, this paper compares the real-time performances of two popular versions of UNIX namely System V Release 4.0 and System V Release 4.2 for the Intel platform.


Aza-Claisen rearrangements (3-aza-Cope rearrangements) have gained an in- creasing interest in synthetic organic chemistry. Originally, the exceptionally high reaction temperatures of this hetero variant of the well-known 3,3-sigmatropic reaction limited their applicability to selected molecules. Since about 1970, charge acceleration enabled a signifi- cant reduction of the reaction temperature to be achieved, and cation- and anion-promoted rearrangements found their way into the syntheses of more complex molecules. The first to- tal syntheses of natural products were reported. The development of zwitterionic aza-Claisen rearrangements allowed the reactions to be run at room temperature or below, and the charge neutralization served as the highly efficient driving force. After overcoming several teething troubles, the method was established as a reliable conversion displaying various stereochemical advantages. The first successful total syntheses of natural products incorpo- rating the aza-Claisen rearrangement as a key step emphasized the synthetic potential. To date the aza-Claisen rearrangements are far from being exhausted. Still, an enantioselectively catalyzed variant has to be developed. This review summarizes one decade of investigation efforts in this area.


Abstract In recent observational studies of atmospheric blocking it was found that the blocking region is characterized by relatively low and uniform values of the isentropic potential vorticity. It will be shown that the barotropic vorticity equation on a sphere has modon solutions with similar properties. In these solutions the absolute vorticity is relatively low and uniform in a circular subregion of the sphere. Inside this region, to be associated with the blocking region, the streamfunction has a north–south oriented dipole structure. Outside it the stream-function gives rise to a wavy westerly background flow. The spatial flow pattern and linear stability properties of a representative example are discussed and compared with examples of previously obtained modons. The merits and drawbacks of the new solutions as possible descriptions of atmospheric blocking are considered in the light of the studies mentioned above.
