adrenals. They become swollen and deep red. On section extensive haemorrhages may be found. The cells are pale and swollen, and are in a process of hydropic degeneration. While it is now generally supposed that the absorption of toxins from the injured skin (histamine shock) is the prime factor in the fatal outcome, the marked pathological changes found in the adrenal cortices suggest that acute cortico-adrenal insufficiency (secondary to the above-mentioned pathological changes in the cortex) plays a prominent part in these deaths. It is quite within the bounds of reason to expect that the generous administration of cortin in such cases would prevent an otherwise inevitable fatality. Summary


A theoretical model is developed to describe quasi-one-dimensional organic ferromagnets after considering the interchain interaction as an interchain electron-transfer. By employing the mean-field approximation, four energy bands which exhibit three-dimensional anisotropic aspect are obtained. When the interchain coupling increases, the energy gap decreases. In the case of small dimerization order parameter, due to the interchain coupling, the band gap may disappear and the conjugated π-electrons in the main chain show ferromagnetic order in the ground state.


Global warming will result in the melting of glaciers and frozen soil, as well as increasing sea levels, endangering not only natural ecosystems but also humanity's survival. Therefore, the world should speed up its response to climate change and low-carbon transition. However, there are conflicts of interest between developed and developing countries, and some contradictions are deep-rooted. In order to find the future survival path of humanity, all countries need to make concessions to realise joint cooperation. The article studied the two significant issues facing international cooperation to achieve lowcarbon and examined the difficulties faced by the world's top ten greenhouse gas emitting developed and developing countries in the process of the low-carbon transition. Based on the research analyse and Covid-19 impact, some feasible suggestions for individuals and countries are put forward to achieve decarbonisation.


UNTIL recently most of the books by disarmers said little about the dirty business of nuclear strategy and most strategists made only occasional references to the Utopia of disarmament. And so it also was with the actual policies—military vs. disarmament—of the nuclear nations. So long as this split persisted there was little chance of disarmament being seriously considered, and so long as the best military analysts considered nuclear weapons useful and even vital to Western defense—as a great many of them did—there was little hope for nuclear disarmament. But in the last few years this split between armers and disarmers has begun to be bridged by an increasing number of men who analyze from both perspectives at once, and by a shift in the consensus on the specific question of the usefulness of nuclear weapons— a shift largely reflecting the steady increase in Soviet nuclear power. These trends were given a considerable assist from these two excellent works by eminent Englishmen, both of whom assume that nuclear parity (and therefore, they believe, nuclear uselessness) is upon us, and both of whom are concerned with deterrence and disarmament, and how to get from one to the other.


Purpose: Sensitization to methacrylic monomers is a significant problem in dental occupational exposures. The purpose of the present study was to evaluate the dynamics in contact sensitization incidence to methacrylic monomers during the educational course of dental technician students. Material and Methods: Skin patch testing with methyl methacrylate, triethylene glycol dimethacrylate, ethylene glycol dimethacrylate, 4-tolyldiethanolamine, N,NDimethyl-4-toluidine, 1,4-butanediol dimethacrylate, tetrahydrofurfuryl methacrylate, formaldehyde and glutaraldehyde was performed among 150 dental technician students (38 – 1st, 40 – 2nd and 38 – 3rd year of education); 34 students without educational exposure to metals served as controls.. Chi square test and Fisher Exact Test were used in data analysis (p < 0.05). Results: The incidence of sensitization to 4-tolyldiethanolamine in the group of dental technician students 2nd and 3rd year of education was significantly higher, if compared with those from the 1st year, as well as with the control group (P=0.042). The sensitization rate to 4tolyldiethanolamine was the highest recorded among all methacrylic monomers tested for the whole tested population. The incidence of positive patch tests to formaldehyde was the highest recorded for all defined groups. Higher were sensitization rates among dental technician students 2nd year of education vs. no cases in the control group. Conclusions: Our data indicate high and increasing with the duration of educational exposure risk of contact sensitization to 4-tolyldiethanolamine among dental technician students, and this substance could be outlined as a sensitizer of prominent importance. No significant differences were established concerning the other tested methacrylic monomers. We accept the main role of consumer and environmental exposures for the manifestation of formaldehyde sensitization. Adequate preventive measures and information should be provided during the practical educational course of dental technician students. General population need to be well informed and the European Union regulations to be properly applied.


The dissociation of Nen2+ clusters is theoretically investigated by extending the liquid drop model to include vibrational delocalization and finite temperature effects as well as by using explicit path-integral molecular dynamics simulations with a polarizable many-body potential. Both methods show that quantum nuclear effects are not sufficient to explain the particularly low appearance size of nc = 288 reported experimentally, hereby suggesting that other mechanisms, possibly electronic, play an important role.


A setup for diffraction and diffuse scattering studies on biological crystals, in the wavelength range 1.5–0.9 A, is operating on the superconducting wiggler line of the storage ring DCI at LURE. Double focusing and rejection of harmonic contribution are achieved by combining two Bragg reflectors with elliptical curvature, respectively, a Si or Ge single crystal and a large W/Si interferential reflector (layered synthetic microstructure). Area detectors include photographic films and an imaging plate scanner device.


It has been proposed that the putamen is more involved during self-initiated (SI) nov el movements than in externally-triggered (ET) ones. Furthermore, increased activation of the subthalamic nucleus (STN) has been linked with movement selection and inhibition of concurring motor events. However, their role remains unclear in the context of bimanual finger movements. In this study, we used 3T fMRI to study their role in the context of a bimanual finger movement task, in healthy right-handed young adults. For each hand, the participant had to perform a SI condition, an ET condition and a control one. We focused on three contrasts, SI vs. control, ET vs. control, and SI vs. ET conditions. The results showed significantly increased activity in the putamen bilaterally in aIl contrasts, except, for the left hand, when the ET condition was compared to control. The observed results provide further evidence that the putamen is required for the planning and execution of non-routine movements, particularly for SI novel movements. Significant increased STN activation was observed when comparing SI to control for the left and the right hand. However, when comparing the SI conditions to the ET conditions, it was only observed for the left hand. The patterns of activity observed in the STN indicate its involvement in movement selection and inhibition of concurrent ones. FinaIly, throughout the contrasts, greater and larger cortical and subcortical activation was observed for conditions using the left hand than the right one, which leads us to propose that in right-handed humans, fine motor movements of the left hand require more resources, both cortically and subcorticaIly.


High Voltage Electrical Equipment utilised in the New Zealand National Grid has been strengthened to survive earthquakes of differing intensities using a variety of approaches. The applicability of past solutions is discussed, and the application of a base isolation system using low load rubber bearings for the strengthening of Capacitor Filter Banks at Haywards Sub-station is detailed and contrasted to the latest solutions used for the recent HVDC Upgrade project.


Torsion angles encode information on the backbone secondary structure and on the conformation of the side chains of a protein. Solid-state nuclear magnetic resonance (NMR) relies on the orientation dependence of nuclear spin interactions and can be used to determine torsion angles. This article describes various techniques developed in the last decade for applications in proteins under magic-angle spinning (MAS) conditions. We discuss both the techniques suitable for applications in proteins with selectively introduced nuclear spin labels and multidimensional dipolar chemical shift correlation methods permitting simultaneous site-specific measurements of a large number of torsional restraints.

An environmentally compatible wood preservation was attempted by using whey protein isolate (WPI), which is a water-soluble protein and derived from milk whey. Sugi (Japanese cedar, Cryptomeria japonica D. Don) sapwood specimens were impregnated with WPI and heated to denature and insolubilize proteins. The fungal decay test using a brown-rot fungus Fomitopsis palustris and a white-rot fungus Trametes versicolor revealed higher durability of WPI-treated wood than control specimens. Their durability was further improved by adding antifungal components such as boric acid and cyproconazole, and the mass loss of 3% or less after decay test was accomplished.


Tripping of distance relays due to load encroachment is one of the common causes behind major disturbances occur in power systems. Several techniques have been presented in the literature to differentiate the occurrence of load encroachment and the fault in a system. Once an event of load encroachment is observed, loading condition of the power system must be rescheduled to avoid any undesired relay tripping. This paper proposes a receding-horizon Model Predictive Control (MPC) strategy to change load and generation of a power system optimally that takes the apparent impedance seen by vulnerable distance relays away from their zone-3 boundaries. To apply MPC technique, a linear state-space model of a power system is developed using sensitivity analysis. Rescheduled load and generation are found by minimizing the total cost required for the change, owing to the constraints of power balance, power carrying capacity of lines and relay operational margins. During step changes in inputs, adequate time gap is provided to ensure the stability of the power system. An oscillation detection technique is developed for the above purpose. At the end, several case studies have been presented to demonstrate the performance of the proposed technique under stressed operating conditions.


The sensitivity of surface acoustic wave (SAW) chemical sensors depends on several factors such as the frequency and phase point of SAW device operation, sensitivity of the SAW velocity to surface mass loading, sensitivity of the SAW oscillator resonance to the loop phase shift, film thickness and oscillator electronics. This paper analyzes the influence of the phase point of operation in SAW oscillator sensors based on two-port resonator devices. It is found that the mass sensitivity will be enhanced if the SAW device has a nonlinear dependence on the frequency (delay ∼ frequency−1). This requires the device to generate and operate in a ωτg(ω) = const region in the device passband, where ω denotes the angular frequency of oscillation and τg(ω) denotes the phase slope of the SAW resonator device. A SAW coupled resonator filter (CRF) that take advantage of mode coupling is considered in realizing such a device to help in shaping the phase transfer characteristics of a high mass sensitivity sensor. The device design and simulation results are presented within the coupling-of-modes formalism.


Male frogs typically call near water at dusk to attract females for breeding. During the breeding season, male treefrogs also emit diurnal "tree calls" or "rain calls" from the tops of trees. Very little is known about tree calls, although many treefrogs use them. Tree calls may be used to attract females, deter males or be triggered by weather conditions favorable for breeding: high temperature and relative humidity, and a drop in barometric pressure. As dusk approaches, male treefrogs continue tree calls from lower in the trees, and if conditions are favorable, jump to the ground and travel to a nearby breeding pond where they begin their repetitive nocturnal mating calls. The scant published information is mostly descriptive and does not address the fitness benefit of calling from treetops far from breeding ponds. My goal was to determine the function of tree calls based on their environmental, behavioral, and acoustic characteristics. My data indicate tree calls are not rain calls. Each treefrog species that I studied (Hyla femoralis, H. gratiosa, and H. squirella) called most frequently at different combinations of mean environmental characteristics (temperature, relative humidity, and barometric pressure). Hyla femoralis and H. gratiosa gave tree calls at ambient air temperatures that differed significantly from the distributions recorded when no treefrogs called. Temperature, relative humidity, and barometric pressure distributions of calling activity differed significantly among all three species and from the distributions recorded when no treefrogs called. Hyla squirella called most often at a significantly different mean relative humidity of 1015 mbar; whereas H. gratiosa and H. femoralis called at a median1017 mbar. Means and fluctuations (summarized as SD) of the three weather parameters explained significant variation in tree calling activity (3260%). Tree calling activity for all three treefrog species were also not significantly affected by


In this study, the robust detection problem of intermittent faults (IFs) for linear stochastic systems subject to time-varying parametric perturbations is addressed. The authors consider the case that an IF appears and disappears non-deterministically, and lasts for random periods of active time with unknown magnitudes. A novel robust fault detection method is presented to detect all the appearing time and the disappearing time of an IF. Based on the output of an observer-type residual generator, a novel robust residual is constructed by utilising a sliding-time window. Two hypothesis tests are provided to detect all the appearing and the disappearing time, respectively. Moreover, the detectability of the IF by using the proposed robust detection scheme is defined in a probabilistic sense, and a sufficient detectability condition is presented within the given framework. Capacities of false alarm rates and missed detection rates are rigorously analysed. Finally, the application of the presented scheme is illustrated on a simplified radial flight control system and the results show that the IF can be effectively detected in the presence of perturbations and noises.

Toni Morrison`s Home describes the unspeakable traumas of main characters, Frank Money and Cee. Their traumas are from Korean war experiences, poverty, racial discrimination and the evil experiment of a white doctor. Morrison shows a long cure process of treating unbearable traumas. Like Morrison`s other novels, there are also wise black women and men who can heal the wounded Cee and help Frank find a safe way to rescue his sister. They are healers unlike the selfish white doctor, Beau who is reflecting a long history of medical apartheid in U. S. A. In this paper, I point out the importance of italicized chapters of this novel which are similar to the counseling session between a psychotherapist and a patient. Those chapters give Frank clarity and make him find a method to repent his sins and heal his traumas. At the ending of this novel, Frank and Cee give a proper burial and mourn for an unknown black man under the beheaded and split but surviving sweet bay tree. Morrison emphasizes the fact that like that tree, they will survive regardless of their misfortune and burdensome traumas.


Background: Postpartum ritual hot bath is one of the harmful cultural beliefs commonly practiced in Northern Nigeria. It is linked with health hazards especially among women with hypertensive disorders of pregnancy. Methodology: It was a cross-sectional study conducted among 199 pregnant women over the period of 3 months. Ethical approval was obtained from The Kano State Ethical Committee. Questionnaire was administered among consenting pregnant women. Information on sociodemographic characteristics and practice of hot bath was obtained. Data were analyzed with SPSS version 17 computer software (SPSS Inc., SPSS Statistics for Windows, Chicago, IL, USA). Results: One hundred and ninety-nine pregnant women were recruited for the survey. The mean age ± standard deviation was 28.09 ± 5.55 years. The rate of hot bath was 56.80% and the days spent taking the hot bath ranged from 4 to 40 days. An average of 195.41 ± 96.050 Naira was spent on firewood per day for the hot bath. The method of boiling the water was mainly the use of firewood 87 (78.40%). They mainly used leaves 76 (68.50%) and towel 35 (31.50%) for bathing. The responsibility of the cost of the hot bath was mainly on husband 102 (91.90%). The hot bath was enforced mainly by the parents 68 (61.30%). Up to 82 (73.90%) of the respondents were ready to abandon the hot bath if alternatives such as drugs are provided. Conclusion: The prevalence rate of hot bath was 56.80%. The burden of its financial implications lies mainly on husbands leading to other social and financial problems.


The equation for the gravity anomalies of a prismatic model of finite strike length is derived. The density contrast is assumed to decrease with depth and is approximated by a quadratic function. A non-linear optimisation technique based on the Marquardt's algorithm is developed to find the various parameters of the prismatic model. Synthetic anomalies of the prismatic model of different semi strike lengths are calculated and interpreted by two different programs. A field profile from the San Jacinto grasben is interpreted for different half strike lengths. A listing of the computer program is given


Objective To understand the epidemiological trend of acquired immune deficiency syndrome(AIDS) in Dechang County so as to provide a scientific base for prevention and control of AIDS.Methods Descriptive epidemiological analysis was conducted on the AIDS epidemic data in Dechang county.Results From 1995 when the first case of HIV infection was confirmed to August 2011,a total of 262 cases of HIV/AIDS were reported with a total infection rate of 18.95/100 000.From 2008 to 2010,the reported infections showed rapid growth.The annual infection rate of male was 26.57/100 000 and female 11.05/100 000 with a significant difference(χ2=43.94,P=0.002).The ratio of male to female infections was 2.49∶1.Most of the AIDS cases were young adults aged between 20 and 45 years and old people aged between 55 and 75 years old who occupied 93.49% of the total infectious cases.The number of reported AIDS cases of farmer and unknown occupations accounted for 82.4% and there was an obvious occupations peak.Most patients in the county were infected by heterosexual sexual contact and injecting drugs,which accounted for 64.89% and 32.82% of the total respectively.The AIDS cases of 29 infected couples and 3 mother-to-child transmission.Conclusions AIDS epidemic growth is rapid in Dechang county with the situation being quite grim.We should enhance the AIDS prevention propaganda in the publicity,to raise national awareness of AIDS prevention.The related departments should cooperate to regulate the illegal entertainment and strengthen the management of migrant workers.The counseling and testing network should be improved so as to raise the detection rate and control the spread of AIDS.


A recent survey of similarity indices by Hubalek has shown that the index due to Ochiai is one of the few satisfying rather stringent conditions. It is shown that the Ochiai index has a geometrical interpretation that can be exploited to yield a critical value for separability of two habitats on the basis of their avifauna. This critical value is used to analyse data on bird habitats and is compared with the results of a null hypothesis test on the data. In addition, use is made of the indices of Jaccard and Sokal & Michener. When the null test is used at the 5% level, all three indices agree in separating the habitats. The presence of a critical value of the Ochiai index gives it an advantage. A table of critical values is given for various numbers of species.


Inkjet-printing is a very promising technology for the development of microwave circuits and components. Inkjet-printing of conductive silver nanoparticles and carbon nanotubes (CNTs) inks on an organic flexible paper substrate is introduced in this study, in order to characterize the CNT patterns. The CNTs are printed within a gap of coplanar and microstrip lines used as test structures. The suggested method can be exploited and used to characterize different CNT inks used in different inkjet-printed microwave devices.


Eight electronic properties; HUMO, LUMO, HOMO-LUMO energy gap, dipole moment point-charge, dipole moment hybrid, molecular weight, heat of formation and zero-point energy of 60 normal and branched alkanes were examined using topology molecular indices. All the electronic properties were calculated using semi-empirical self-consistent molecular orbital theory. The relationship of electronic calculation properties with seven models of topology indices based on degree and/or distance were obtained in terms of their correlation, regression and principal component analysis. Most of the properties were well-modelled (r2 > 0.82) by topology molecular indices except the dipole moment point-charge and hybrid. The PCA resulted in 7 properties and 60 structures of alkanes that produced two principal components with eigenvalues of greater than 1. The first principal component explained 60.388%, while the second principal component explained 26.457%, bringing a cumulative value of 86.845% to the data variation.


In the present study, a total of 330 specimens the red mullet, Mullus barbatus ponticus caught in the Black Sea coasts near Sinop, Turkey were investigated throughout a 1-year period for their metazoan parasite fauna. Thirteen metazoan parasite species, Loma sp., Proctotrema bacilliovatum, Galactosomum lacteum (metacercariae), Progrillotia dasyatidis, Nybelinia sp., Scolex pleuronectis (pleurocercoid), Hysterothylacium fabri, H. aduncum, Ascarophis valentina, Capillaria sp. Contracaecum sp., unidentified larval nematode (L2) and Acanthocephaloides irregularis were identified. The overall infection prevalence and mean intensity values were 97.88% and 34.12±5.23 parasites per infected fish, respectively. Proctotrema bacilliovatum was the core species with infection prevalence of 70.61% and mean intensity value of 29.09±7.01 parasites per infected fish. The infection indice values for each parasite species were also determined and discussed according to season, length classes and sex of fish. This paper is the first report on metazoan parasite fauna of the red mullet in Turkey.


Data-flow analysis of scalar variables and data dependence analysis on array elements are two important program analyses used in optimizing and parallelizing compilers. Traditional data-flow analysis models accesses of array elements simply as accesses to the entire array, and is inadequate for parallelizing loops in array-based programs. On the other hand, data dependence analysis differentiates between different array elements but is flow-insensitive.
This paper studies the combination of these two analyses—data-flow analyses—data-flow analysis of accesses to individual array elements. The problem of finding precise array dataflow information in the domain of loop nests where the loop bounds and array indices are affine functions of loop indices was first formulated by Feautrier. Feautrier's algorithm, based on parametric integer programming techniques, is general but inefficient. This paper presents an efficient algorithm that can find the same precise information for many of the programs found in practice. In this paper, we argue that data-flow analysis of individual array elements is necessary for effective automatic parallelization. In particular, we demonstrate the use of array data-flow analysis in an important optimization known as array privatization.
By demonstrating that array data-flow analysis can be computed efficiently and by showing the importance of the optimizations enabled by the analysis, this paper suggests that array data-flow analysis may become just as important in future optimizing and parallelizing compilers as data-flow and data dependence analysis are in today's compilers.

The MuSEUM collaboration is planning measurements of the ground-state hyperfine structure (HFS) of muonium at the Japan Proton Accelerator Research Complex (J-PARC), Materials and Life Science Experimental Facility. The high-intensity beam that will soon be available, the H-line, allows for more precise measurements by one order of magnitude. We plan to conduct two staged measurements. First, we will measure the Mu-HFS in a near-zero magnetic field, and thereafter we will measure it in a strong magnetic field. We have developed two microwave cavities for this purpose. Furthermore, we evaluated the systematic uncertainties from such a fluctuation of microwave fields and confirmed the requirements for the microwave system; we use a microwave field distribution calculated with the finite element method.


Tanzania is one of the third world countries and among the world's poorest county. It depends on agriculture which provides 80% of all employment and contributes to about 1⁄4 of GDP. Its financial sector has inflated in the recent years as a result of competition with foreign commercial banks. In line with good services they provide, the interest rates of these banks are higher thing which creates trouble to customers during loan repayments. Also their loan provision criteria include collateral which is defined as the huge obstacle to low income earners and those who live below poverty line. The alternative way which enables lower-income group to access loan is Savings and Credit Co-operative Societies (SACCOS). Contribution of SACCOS in Tanzania economy is of outstanding importance, but yet the country lags far behind. For SACCOS to continue to exist and stay aggressive it must adoption and use ICTs. Literatures show that there are several SACCOS which are not using ICTs. For those few which managed to adopt ICTs, it had been discovered that they are facing numerous challenges. So this study aimed at identifying factors which hinder SACCOS from adopting ICTs in their operations as well as recommending approaches which their implementations will motivate ICTs adoption. Primary and secondary data were collected by using observation and desk research technique. findings shows that factors which hold back SACCOS from adopting ICTs are poor infrastructure, absence of electricity, low capital, lack of ICT expert and bylaw. Based on findings, researcher proposed framework that will guide and enable SACCOS to adopt ICTs. Proposed framework contains four significant components which are members of SACCOS, government, donors and Banks.

Simulated data were used to investigate systemati cally the impact of various orderings of step difficul ties on the distribution of item information for the par tial credit model. It was found that the distribution of information for an item was a function of (1) the range of the step difficulty values, (2) the number of step difficulties that were out of sequential order, and (3) the distance between the step values that were out of order. Also, by using relative efficiency compari sons, the relationship between the step estimates and the distribution of item information was used to dem onstrate the effects of various test revisions (through the addition and/or deletion of items with specific step characteristics) on the resulting test's precision of measurement. The usefulness of item and test infor mation functions for specific measurement applications of the partial credit model is also discussed.

DATA on chemical composition of many of the freshwater fishes of our country is not available and hence an attempt has been made to analyse as many as thirty-six species. The chemical composition of fish varies widely from species to species and season to season. There is also individual variation in the same species. A knowledge of chemical composition is essential in order to compare its value as food with other protein foods. Stansby (1954) has elaborated on the importance of chemical analysis.


Anahtar sozcukler: aort kapagi, bruselloz, endokardit, protez kapak SUMMARY A Case of Prosthetic Valve Endocarditis due to Brucella melitensis Treated with Antibiotic Treatment Endocarditis is a rare but fatal complication of brucellosis. We report a 75 year old male with mitral valve endocarditis due to Brucella melitensis who was completely cured with medical treatment alone. Our case and the literature demonstrate that, in selected patients, antibiotic treatment may be a valid alternative to surgery.


For decades, entrepreneurs have been identified as critical change agents in socio-economic development. It is probably safe to say that some countries have had more success than others in the promotion of entrepreneurship; and in that context it can be argued that South Africa's successes are not yet clear. The promotion of entrepreneurship through the involvement of higher education institutions (HEIs) is by no means an easy task, but they have an important role to play. Although South African HEIs are focusing on various elements of entrepreneurship promotion, there is no clear evidence of an integrated effort from HEIs to develop entrepreneurial skills and activity. The authors argue that without such an integrated effort entrepreneurship development in South Africa is likely to be constrained.


Introduction Behcet disease (BD) is a multisystemic and chronic inflammatory disorder, mainly characterized by recurrent oral and genital ulcers, ocular involvement, and skin lesions, with periods of remission and relapse (1,2). Epidemiological studies have documented that BD is comparatively frequent in countries located around Mediterranean Sea, the Middle East, China, and Japan, along the ancient Silk Route (3). The exact etiology of BD has not fully explained yet, but the disease occurrence is highly associated with a genetic factor, namely human leukocyte antigen (HLA)-B51. Furthermore, genetic studies have established a strong association of HLA-B with cytokine production including high production of tumor necrosis factor (TNF) and decreased production of interleukin (IL)-10. Gene variations have also been observed in inflammatory cytokines, chemokines, and adhesion molecules, leading to vascular inflammation and consequently vascular damage (4,5). BD shares characteristics of both autoimmunity and autoinflammatory. The major features of BD that lead to the classification of the disease as an autoimmune disorder include response to classical immunosuppressive drugs like cyclosporine and azathioprine (6), and involvement of autoantigens such as heat-shock protein 60 (HSP60) in the initiation of the disorder (7). On the other side, specifications of the disease implying the autoinflammatory face of BD comprise high-titer autoantibodies, a rise in the number of antigen-specific T cells, the role of major histocompatibility complex (MHC) class I molecules, clinical periods of recurrent inflammation by neutrophils mainly (8), and effectiveness of anti-inflammatory agents like colchicine (9). Studies show that macrophages produce macrophage inhibitory protein-1alpha (MIP-1α) chemokine and mediate the activation and recruitment of other leukocytes to the sites of inflammation in BD patients (10). Autophagy is an intracellular degradation process and plays a variety of physiological and pathological roles through removing aggregated proteins, infectious Abstract Objective: Overwhelming inflammatory chemokines and cytokines characterize the immunological profile and inflammatory settings of Behcet disease (BD). The connection between autophagy-related genes (ATGs) and various perspectives of innate and adaptive immunobiology such as antigen presentation, immune tolerance, lymphocyte development and differentiation, cytokine signaling, and inflammation have been implicated. The aim of this study was to evaluate the mRNA expression profile of ATGs in macrophages of patients with BD. Materials and Methods: Whole blood samples were obtained from 10 BD patients and 10 healthy controls. Monocytes were isolated from the blood samples and then differentiated to macrophages using macrophage colony-stimulating factor (M-CSF). After total RNA extraction and cDNA synthesis, quantitative analysis of ATGs including ATG5, ATG7, ATG12, LC3b, mTOR, RAPTOR, and RICTOR was conducted by SYBR Green master mix and real-time polymerase chain reaction (PCR). Results: mRNA expression of all ATGs was downregulated in macrophages of BD patients compared with healthy controls. It is worth to note that the downregulation of ATG12 and LC3b mRNAs in macrophages of BD patients was statistically significant in comparison to that of healthy control group (P = 0.007 and 0.021, respectively). Conclusion: Considering the role of autophagy in initiation of immune responses and then clearance of dead cells as well as its participation in the development and differentiation of immune cells, downregulation of ATGs in macrophages of BD patients may be involved in uncontrolled immune response and overproduction of inflammatory cytokines.

The constant search for protection the soldier during training and participation in hostilities led us to aspire to develop types of energetic materials of a special nature that qualify them to reach the maximum levels of safety during handling, transportation and uses. In this work, we focus on one of these compounds, which is the main component of the preparation of low sensitive compositions. DNAN is an explosive with low sensitivity. Preparation of DNAN in laboratory scale was performed; explosive characterization was presented. Impact and friction sensitivities of DNAN, heat of combustion and detonation velocity were specified. TGA and DSC were used to investigate the DNAN thermal behavior under specific conditions. It was concluded that sensitivity of DNAN is lower than TNT and the chosen cyclic nitramines. The detonation properties of DNAN are slightly lower than TNT however DNAN is candidate individually or with other explosives to replace TNT in low sensitive compositions to full fill the safety and security manipulation of ammunitions.


With using high speed stroboscopic CCD-camera, method of temporal phase unwrapping is presented. By temporal phase unwrapping it is possible to determine the absolute deformation (surface points displacement) of object. The phase of the wave front is calculated from the recorded hologram by use a two-dimensional digital Fourier transform method. Experimental results are presented. Advantages of temporal phase unwrapping compared with spatial unwrapping are discussed.


Soft ferrite (Mn0.4Zn0.6Fe2O4) and hard ferrite (Co0.4Zn0.6Fe2O4) nanocomposites (x Mn0.4Zn0.6Fe2O4 + (1-x) Co0.4Zn0.6Fe2O4 (where x= 0.25, 0.5, 0.75) were prepared with different weight percent. Crystal structures and microstructures of these composites have been investigated by using X-ray diffraction and scanning electron microscope for composite samples sintered at 900°C/30 min using microwave sintering technique. The effect of composite weight percent on dielectric properties of composites are examined over a wide frequency range (1MHz-1.8GHz) by studying the real and imaginary part of permittivity with available theories. Investigation show variation of mixed ferrites for resistivity and resonating frequency.


Sterile ready-made cotton wool ear wicks are always useful in the practice of otology. To keep the wicks from forming clusters or being stuck together, they may be arranged on the corrugated paper which is a common packing material for fragile things, and so easily procurable. The procedure is simple: A swab is made in the usual way, i. e., by twisting or rolling a thin metal applicator, held between the right thumb and index finger, into a small, thin sheet of cotton wool held firmly between the left thumb and index finger. Now, instead of being withdrawn from the applicator at once, the swab is transferred directly onto a groove of the corrugated papter, cut into convenient sizes. While the applicator is being withdrawn a little pressure from the left thumb or index finger applied to the cotton will make the wick stay in position. Several layers of the


A surface acoustic wave (SAW) propagating in an arbitrarily anisotropic piezoelectric halfspace is considered. The wave interacts with a perfectly conducting and weightless metal disk on the substrate surface by means of the electric potential only, which is coupled to the SAW due to the substrate piezoelectricity. A perturbation theory of the scattering of the plane harmonic SAW by the disk is presented which accounts for the dielectric and elastic anisotropy of the substrate. The solution for electric charge distribution on the disk is given in the form of a fast convergent series easy for computation. The angular dependence of the scattered SAW a large distance from the disk is discussed, and it is shown that the scattering pattern main lobe lies in the shadow area.<<ETX>>


This study examines whether corporate social responsibility is associated with firms' earnings management in an international setting. Using a large sample of international firms, we find a significantly negative association between corporate social responsibility and firms' earnings management. This negative relation holds after we account for potential endogeneity. Our results also suggest that the inverse CSR-earnings management association is more pronounced in countries with low individualism scores, high uncertainty avoidance scores, common law regime, high investor protection, and high human development. Furthermore, our component analysis suggests that the inverse CSR-earnings management association is more prominent in firms with stronger stakeholder governance, higher awareness on environmental issues, and more stakeholder capital. Overall, our results are supportive of the ethical financial transparency hypothesis, the individualistic culture hypothesis, and the uncertainty avoidance culture hypothesis, but not the opportunistic incentive hypothesis.


The Federal Aviation Administration, Office of Environment and Energy (FAA, AEE-100) has developed Version 7.0 of the Integrated Noise Model (INM) with support from the John A. Volpe National Transportation Systems Center, Acoustics Facility (Volpe Center) for development of the acoustic computation module, and from the ATAC Corporation for systems integration, development of the graphical interface, and methods for computing aircraft flight profiles and constructing flight paths, which are processed by the acoustics module. This Technical Manual describes the core technical components in INM Version 7.0, including the flight-path methodology (Chapter 2), along with the basic methodology employed by the INM to compute noise levels or time-based metrics at a single, user-specified observer, or at an evenly-spaced, regular grid of observers (Chapter 3). The noise/time computation methodology includes a description of: (1) computation of the flight-segment geometric and physical parameters; (2) flight-segment noise-level interpolation process; (3) atmospheric absorption adjustment; (4) acoustic impedance adjustment; (5) flight-segment noise-fraction adjustment for exposure-based metrics; (6) aircraft speed adjustment for exposure-based metrics; (7) updated lateral attenuation adjustment; (8) ground-based directivity adjustment for observers behind start-of-takeoff-roll, as well as for computing metrics associated with run-up operations; (9) new helicopter noise modeling capabilities and associated adjustments (including advancing tip mach number, lateral directivity, static directivity and static duration adjustments); (10) metric computation process; and (11) development of a recursively-subdivided irregular grid methodology, which is used for computing noise contours (Chapter 4).


Background: Age at first marriage is associated with poor demographic outcomes such as high fertility and mortality and low contraceptive use. In Malawi marriage could be described as early and universal. The aim of this study is to examine the factors associated with early marriages in Malawi. Methods: Data from the 2000 and 2004 Malawi Demographic and Health Survey (MDHS) are used. Univariate, bivariate and hazard proportional model were used to assess the association between age at first marriage and selected socio-economic factors. Results: The results indicate that marriage in Malawi takes place early and the mean age at first marriage is 17.4 years. Age, education, religion, ethnicity and region are found to be the important variables in explaining age at marriage. Conclusion: The findings of the study indicate that age at first marriage was associated with residing in rural areas, low education, ethnicity, region and being poor. These factors should be considered in designing new strategies to combat rapid population growth and reduce both fertility and mortality in the country. The policy implications of the results are discussed. Efforts to improve the status of women through their increased participation in education should be encouraged.


In the present research estimation genetic and phenotypic parameters associated with birth weight in Holstein Friesian calves were done. The data of the present research consisted of calving records from 1986 to 1991 of Holstein Friesian raised at the Polatl ı Agriculture Farm. The effects of environmental macro-factors such as birth season, year and sex of calves on the birth weight were investigated. According to the result, the least squares of birth weight were 36.79 ± 0.068 kg. The effects of calving season, year and sex on the birth weight were found to be statistically significant (P < 0.01). Repeatability and heritability estimates for birth weight were 0.07 ± 0.041 and 0.29 ± 0.03.

This study was conducted to determine the phenotypic characteristics of the angut pigeon breed, which is native to Şanlıurfa, where pigeon breeding has been done traditionally for a long time and is also one of the domestication centers. In this study, we adopted 146 angut pigeons comprising 72 males and 74 females. Additionally, four different colour variations were determined: yellow angut (41.1%, n = 60), red angut (35.6%, n = 52), white angut (13.7%, n = 20) and black angut (9.6%, n = 14). All the colour variants had a peak crest (upright feathers) costume structure, which was at the back of the head, starting from the end of the neck and extending from ear to ear. Among the gender groups from the measurements obtained in this study; wing length, wingspan, tail length and head width (P < 0.001); shank length and head length (P < 0.01). Differences in beak length and beak width were also significant (P < 0.05). Moreover, the differences in beak length and beak width were significant (P < 0.05). Today, although anguts are morphologically similar to the Demkeş breed in Turkey, they do not have trumpeting sound ability. The trumpeter breeds of fancy pigeons are so named because of their unique vocalizations, which sound vaguely like low laughter. The data obtained on the morphological features of angut pigeons support the hypothesis that angut pigeons are a form pigeon and should be defined as a different breed.

Isovaleramide has been found to exhibit mild anxiolytic activity at low to moderate dosage levels and mildly sedative at somewhat higher dosage levels. In contrast to certain other materials thought to be anxiolytic or mildly sedative, isovaleramide is non-cytotoxic and does not paradoxically stimulate the central nervous system. Isovaleramide is therefore useful as a mild anxiolytic and mild sedative which can be made available to the general public.


We examined the accuracy of data from an affordable personal monitor (Fitbit Flex) compared with that of data from a research‐grade accelerometer worn simultaneously for 7 days; high accuracy would support substitution with this less‐expensive personal activity monitor in future community‐based arthritis research.


A flow reactor has been constructed to study the rate of neutralization of H2SO4 aerosol by NH3. Monodisperse H2SO4 aerosol was generated by a Berglund-Liu vibrating orifice aerosol generator and mixed with NH3 from a permeation tube. The ammonium fraction was measured as a function of time by an instrument capable of distinguishing between the acid and ammonium fractions of sulfate aerosol in real time. Preliminary results indicate that for 'clean' H2SO4 aerosol (i.e., no surface contaminants) the neutralization rate is controlled by the diffusional mass transfer of NH3 to the H2SO4 droplets.

Our data, however, show that among first-time users of ACE inhibitors, the use of captopril


The passive safety systems employed in the design of pressurized water reactor (PWR) can accomplish the inherent safety functions and mitigate the consequences of the postulated accidents. In this paper, a passive residual heat removal system (PRHRs) is designed for a certain nuclear power plant. The RELAP5/MOD3.4 code was used to analyze the operation characteristics of the PRHRs. It shows the PRHRs could remove the decay heat from the primary loop effectively, and the single-phase and two-phase natural circulations could respectively establish in the primary circuit and the PRHRs circuit.Copyright © 2013 by ASME


A dedicated controller for the beam-position monitor (BPMC) has been developed at KEK, which is scheduled to be installed into the 50-GeV main ring of the J-PARC [1, 2] project. The data acquired from a beam-position monitor (BPM) is calculated in the BPMC, and the result is sent to an EPICS device controller. An EPICS device controller for the BPMC is presently under development. It uses a VME-bus computer with an Intel processor, and runs a Linux operating system. The development started with 16 BPMCs. The performance of system-loading has been analyzed, including the usage of CPU power, the usage of memory, and the network traffic. The result shows that the EPICS device controller has sufficient capacity to control 16 BPMCs.


Aim: The study was conducted to evaluate the internal fit and marginal adaptation of custom-made Pressable compared to CAD/CAM PEEK post and core at three levels. Methodology: Twenty-eight extracted maxillary central incisors were prepared for custom post and cores. Acrylic resin patterns were fabricated and divided into two groups: CAD/CAM group: The resin patterns were directly scanned and milled from modified PEEK blocks and Press group: Patterns were pressed with PEEK granules. The cement thickness was measured at four standardized points and the vertical marginal discrepancy was measured at twelve points using scanning electron microscope. One Way-ANOVA and Tukey`s post hoc test were performed to compare between the sections of each group; while Independent T-test was performed to compare between the two groups at different sections. Results: Regarding CAD/CAM group, the mean cement thickness was the highest in the coronal section (85.57±17.81) followed by the middle (72.87±18.57) then the apical (45.92±18.73). While for Press group, the middle section showed the highest mean cement thickness (50.99±15.98), followed by the coronal section (39.70±18.16), the apical section (21.37±4.30). Comparing the two groups, CAD/CAM group had a significantly higher internal gap in all sections (P=0.0001). Among cores marginal adaptation, no significant difference in means of all surfaces was revealed between the CAD/CAM (98.83±13.90) and press (95.08±13.91) groups (P=0.54) Conclusion: Within the limitations of this study, pressed PEEK post and cores achieved superior internal fit compared to CAD/CAM. Neither CAD/CAM nor pressing technique influenced the marginal adaptation of PEEK cores and both were within the clinical acceptance range.


Rapid advances in information and computer technologies are a challenge for information systems professors. Not only do these advances frequently make course materials out-of-date, professors may struggles to stay current with popular technology applications. These forces lead to a situation in which students may be more technologically savvy than their professors. This panel offers a variety of perspectives on this issue and its impacts on information systems education.


Number Sense introduces the readers to sense behind numbers. In the current era while many books are focusing on how to computestatistics this book focuses on the story behind the numbers. It questions and investigates the purpose of generating those statistics, the reasons behind defining publicly used indices and measures in a certain way, the intent and motive of the organizations publishing those statistics, the abuse of these statistics to misguide the consumers of these statistics, and at times simply identify the traps that statisticians can inadvertently fall into.

Two siloxane copolymers containing pendant mesogenic units were synthesized by reacting the chloromethyl groups of a siloxane precursor copolymer with potassium phenolates of aromatic azomethine mesogens. Their structure was confirmed by spectral methods (FT-IR and NMR) and their thermotropic behavior was studied by polarized optical microscopy (POM), differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD). Both copolymers showed liquid crystalline behavior over a large temperature range, with isotropization interfering with thermal decomposition. However, in comparison with previously reported telechelic siloxane oligomers containing similar mesogenic groups, lower melting temperatures and more ordered mesophase were observed in the case of the copolymers. Thermogravimetric analysis (TGA) and molecular modeling were used to better understand and complete the thermotropic investigations.


Thin steel plates galvanized are used for steel-framed house, roof and wall and their metal fittings of building structures. There are corrosion, fatigue, thermal effects and surface defects in the factors of deterioration of steel material. Corrosion occurs such as a thin steel plate, as well as the usual steel caused by the presence of moisture and oxygen, depending on the environmental conditions, the degree and form of the corrosion are different. Not only flat portion but also cut edge portion of metal fitting using a thin steel plate in corrosion resistance are different. In this paper, combined cyclic test of various specifications of metal fittings for folded-plate roof using thin steel plates is conducted and corrosion resistance of metal fittings is evaluated.


Nature is a supraindividual limit for the individual self-definition of man. Our identities differ because we see the world in dissimilar ways. This article suggests the distinguishing of the three main anthropological paradigms that presuppose our understanding of what the world is and how we identify ourselves. These are the mytho-metaphysical, the physically natural and the sociocentric anthropological paradigms. The author also mark the key anthropological dispositions which are the relations "man — nature", "man — others" (or: "man — people"), "man — time" (or: "man — history"), "man — spirit" ("man — the ideal", in some cases: "man — the Absolute"), "man — body" and, finally, "man — death". By interpreting these dispositions in accordance to the logic of a particular paradigm we clarify (or construct) what it


A curious and unexpected result of the impact of P/Shoemaker Levy 9 with Jupiter was the production of enormous amounts of molecular sulfur (S 2 ). Here we show that S 2 is the natural product of disequilibrium chemistry at low pressures in shocked jovian air, its formation a byproduct of hydrogen recombination. The species observed by the HST − S 2 , CS 2 , and H 2 S − imply that the G fragment penetrated the NH 4 SH cloud but did not reach the water table. A typical impact within or below the NH 4 SH clouds produces about 0.03-0.1 impactor masses of S 2 . Because comets are relatively hydrogen-poor, SO 2 , not S 2 , is the major product of shocking a water-rich comet, while S 2 , CS 2 , and OCS are major products of a dessicated comet. In all cases we find that as the gas cools S 2 converts to the stable low temperature allotrope S 8 , although other chemical fates not modeled here might intervene first.


We propose a theoretical framework that explores the accumulation of work interruptions and their effects. Most research studies have dealt with interruptions as isolated phenomena, ignoring the simultaneous or sequential occurrence of interruptions common in everyday life. We fill this gap and provide insight into the process of the accumulation of interruptions by mapping deep-level regulation onto an observable sequence of actions. Furthermore, we explain how cumulative interruptions can lead to qualitatively different effects because of the interaction and joint development of isolated effects, identifying some mediating and moderating factors. In doing so, we disclose the relationships between the effects of single interruptions found in laboratory studies and the impacts on health and well-being of multiple interruptions found in applied research.


Little is known about the mechanisms that regulate the assembly of microbial communities in the river–sea continuum. Here, we performed HiSeq paired‐end sequencing of the V4 region of 18S rRNA gene, using both DNA and RNA extracts, to identify protist communities in the surface and bottom water layers along a transect of the Pearl River–South China Sea Continuum (PSC) during the wet (summer) and dry (winter) seasons. We found that during the summer but not during the winter, protist communities, identified from their DNA or RNA signatures, could be better explained by mass effects and species sorting, respectively. Moreover, protist diversity in the DNA and RNA surveys exhibited similar trends along the transect, that is, a linear upstream‐to‐downstream decrease during the summer and a weakly U‐shaped curve during the winter. In contrast, the taxonomic compositions in the DNA‐ and RNA‐derived communities were remarkably different during either the summer or the winter. In summary, the results of our DNA and RNA surveys revealed the temporal assembly of protist communities in the PSC, which suggests that protist diversity and composition are highly responsive to the hydrographic conditions of the river–sea continuum.

Within the context of sustainable housing, considerable research attention has been on different devices and techniques to lower energy consumption and alternative, environmental-friendly alternatives to generate energy. Recently, scholars engage increasingly in the economic aspects of these devices and techniques. This study elaborates on the study of Kulcar et al. [1], which have investigated the economy of exploiting a two-stage heat pump with heat exchanger using low-temperature geothermal sources for building heating purposes. The results of the analysis suggest that under the circumstances defined in [1], the system is an interesting investment from a financial viewpoint. However, the results turn out to be strongly dependent on the evolution of the electricity and heat prices. It turns out that the net present value of the investment is more sensitive to changes in heat prices than it is to variations in electricity prices.

A survey was conducted to assess the socio-economic status of the fishers of the old Brahmaputra River in Mymensingh Sadar Upazila from April 2011 to March 2012. Data were collected from randomly selected 30 traditional fishermen of Kagdahor, Shambhuganj, Kawatkhali, BAU Campus, Shesmor, Sutiakhali, Char Kalibari, Char Ishwardia and Char Nilakshmia using a well-structured questionnaire. The research revealed that besides fishing, the fishers occasionally undertook a variety of non-fishery related activities. The average annual income ranged from 25,000-84,000 BDT which significantly depends on fishing effort, season of the year and market price of fish. Majority of them belonged to age range 15-30 years (59.25%). Almost 63% of the fishermen were illiterate and cannot write their names, while only 14.81% had received education up to primary level. It was also revealed that family size of 60% of the fishermen were medium consisting of 5-7 members while only 10% had small family size of 2-4 members. Despite their low income and large family sizes, 80% of the fishermen were living in semi-constructed houses. Sometimes for coping with adverse situation many of them took loans from different national and local NGOs like BRAC, ASSA. A declining trend of fish resources in the river and lack of working capital were identified as the major constrains for the fishers of the Old Brahmaputra River. Res. Agric. Livest.

A one‐dimensional fluid model in which the pair interaction potential is exponential and repulsive is considered, and the equation of state in the ``long‐range'' limit is determined exactly. This model is complementary to one studied by Kac, in which the pair potential consists of a hard core and an exponential, attractive tail. In that model a phase transition occurs, but in the current model there is no phase transition. This fact lends support to a conjecture of Ruelle that no phase transition occurs if the potential is bounded. The possibility of applying the method of Kac to a wider class of potentials is suggested, and some of the mathematical difficulties yet to be overcome are outlined.


A primary objective of long-span bridge health monitoring is to obtain the information on bridge condition through online monitoring of the structural performance.Also,health monitoring helps to verify the design approaches and to validate the analytical models of bridge structures.In addition,the unknown issues and the uncertainties involved in the structural mechanics and the environmental condition of a long span bridge may be studied through health monitoring.In this paper,after a brief overview of the development of bridge health monitoring,the connotation of bridge health monitoring is pointed out in an extended sense.Related issues on the design of monitoring system,including the principles of system design and the monitoring items for long span bridges are discussed.


Introduction Chlamydia is the most commonly notified infection in Australia; most diagnoses are in young people, and re-infections are common. Re-infection leads to onward transmission and increases the risk of reproductive morbidity and HIV transmission. Guidelines recommend re-testing 3 months following treatment to detect re-infections. We assessed trends in re-testing after a chlamydia diagnosis in Sexual Health Clinics (SHCs) in New South Wales (NSW) over a 5-year period and factors associated with re-testing. Methods Routine patient data from 2009 to 2013 were extracted from 33 SHCs. A Chi-2 test was used to assess time trends in the proportion re-tested in 2–4 months following a chlamydia diagnosis and also 2–12 months, in a range of risk groups. Multivariate logistic regression was used to determine demographic, risk behaviour and clinic factors associated with re-testing at 2–4 months, adjusting for clinic clustering. Results Overall 8,646, chlamydia diagnoses were analysed and 1,281 (15%) were re-tested in 2–4 months (23% of GBM, 25% of sex workers, 12% of young heterosexuals aged 5 times (aOR: 3.11,95% CI: 2.62–3.70, p Conclusions Re-testing at 2–4 months after a chlamydia diagnosis increased over time, but remains low. GBM and sex workers were more likely to be re-tested, perhaps because they were attending anyway. Attending clinics with SMS reminders increased the likelihood of re-testing. Additional strategies, such as home-collection, may be needed to increase re-testing in young heterosexuals.

Ion scattering spectrometry (ISS) and concurrent secondary ion mass spectrometry (SIMS) were used to determine the depth profiles of anodic barrier oxide films grown on tantalum and type 1100 aluminum. The sputter rate in each case was determined from the film thickness measured by the anodic overvoltage, and the penetration time determined by the decrease in intensity of the metal oxide fragment observed using SIMS. A mixture of helium and neon ions was used to sputter aluminum oxide films in order to observe ion scattering of helium by oxygen, while taking advantage of the higher sputtering rate available with neon. A comparison of sputter rates for helium and neon on tantalum oxide indicated that neon sputtered the film at a rate eight times that of helium. SIMS depth profiling of the residual boron in the anodic aluminum oxide indicated a mixing effect which did not permit adequate resolution of the interface between the oxide film and the underlying metal.

Mobility management has been an important focus in recent years due to the growth of mobile users. Besides mobile IP (MIP) standard, there are many proposals for mobility support in the literatures such as application mobility using session initiation protocol (SIP) [1] and terminal-assisted mobility [2]. With the availability of many wireless access technologies, vertical mobility becomes an important focus to take advantage of the various technologies. With these various access technologies exhibit different characteristics in bandwidth, delay and coverage, the issue of maintaining users' perceived quality-of-service (QoS) across these technologies arises. Even though the availability of multiple technologies increase the coverage, the variability of bandwidth and delay introduces difficulties for applications to run while maintaining the QoS. This QoS issue is important considering the growth of mobile users and real-time applications in this mobile environment. In this paper, we propose a QoS framework in a mobility scenario to cater for applications that can adapt to the variability of bandwidth and delay across the different technologies, and also across different access points. Through our framework, end-to-end QoS signaling is facilitated between the terminals; adaptive applications thus can take advantages of this signaling to maintain users' perceived QoS.


ABSTRACT The basic aim of this paper is to discuss the concept 'Knowledge Democracy' (KD) and what it can mean in the school context, its implications on knowledge production and dissemination and on the educational practices. We try to enrich this discussion by presenting action research projects to provide case studies of how thinking about KD can reshape educational practice. We consider that the discussion on KD has to be enriched as the concept seems very promising with good prospects towards school's democratization. On the other hand, as it is quite new, it can encompass internal contradictions that can cause problems at the level of practice. So, we consider very important any contribution to this discussion not as another theoretical sample of the debate on the 'politics of knowledge', but because any improvement at the thinking of the issue can be reflected on school practices. Any challenge to traditional politics of knowledge can lead to a deeper understanding of the world of schooling and to transformations through new discourses and new approaches to teaching and learning in school.


The analysis of the idea of fate by Gregory leads to the following major conclusions: (1) The natural universe is a common sense universe; (2) The identity of things cannot be given by some fatalist state of things; (3) The identity of things is given through προαίρeσις (4) Προαίρeσις is the ground on which demonic influence is exercised but also the instrument for achieving epistemic validity. The idea of the identity of things is repeatedly announced in the early part of the treatise where Gregory of Nyssa is using a terminology connected to Aristotelian metaphysics and more specifically with terms related to the language of being. Keywords: Contra Fatum ; Gregory of Nyssa


We present the results of an experimental investigation of the striking flow structures that may arise when a vertical jet of fluid impinges on a thin fluid layer overlying a horizontal boundary. Ellegaard et al. (1998, 1999) demonstrated that the axial symmetry of the circular hydraulic jump may be broken, resulting in steady polygonal jumps. In addition to these polygonal forms, our experiments reveal a new class of steady asymmetric jump forms that include structures resembling cat's eyes, threeand four-leaf clovers, bowties and butterflies. A parameter study reveals the dependence of the jump structure on the governing parameters. The symmetry-breaking responsible for the asymmetric jumps is demonstrated to result from a capillary instability of the circular jump. For all steady nonaxisymmetric forms observed, the wavelength of instability of the jump is related to the surface tension, σ, fluid density ρ and speed U of the radial outflow at the jump through λ = (68± 7) σ/(ρU).


Sparse mobile crowdsensing is a crowdsensing paradigm that reduces the sensing cost while ensuring data quality by collecting data sparsely and reconstructing desired data using inference algorithms including machine learning algorithms. However, real-time inference of spatial information with sparse mobile crowdsensing has not sufficiently considered the change of temporal characteristics of data. As a result, the accuracy of the reconstructed data can deteriorate over time. Therefore, this paper proposes a framework that periodically updates a machine learning model used for reconstructing data by evaluating the importance of the data in terms of both inference and re-training and giving priority to collecting important data.


Honolulu International Airport is one of the dozen busiest airports in the United States. It provides a port of entry for foreign flights and both domestic and interisland terminals. For Hawaii's airport engineers and planners, this status makes short- to medium-term air travel forecasts essential, particularly for landside applications. A unique model system is described with separate models for each origin region or country. The models are estimated with the Cochrane-Orcutt regression procedure. Major explanatory variables include the gross national product (GNP), gross domestic product (GDP) (in various forms), and the consumer price index (CPI). Exchange rates, strength of currencies, and variables for wars, recessions, and airline strikes are also introduced. The models adhere closely to the actual number of arrivals, and all variables perform as expected. The USA model has an overall error rate (for the 18 years of the estimation span) of less than 0.05% and annual extreme errors ranging from -6.4% to 5.7%. The Japan model also has an overall error rate of less than 0.05% and annual extreme errors ranging from -7.5% to 10.4%. Near-future values for explanatory variables can be obtained from major economic organizations, thus the use of the model system requires only that planners update variable values annually from regularly issued publications. Long-term forecasts are more difficult due to the lack of published data. In those cases, the user must resort to a combination of trend extrapolation with ARIMA, as shown in this discussion, and educated estimates based on contemporary macroeconomic literature.


Given their high cost, many students no longer buy textbooks for all of their courses, impacting their learning and performance in these courses. This is especially prevalent at community colleges. Open (digitally free) textbooks constitute one solution to this problem, but the latest national survey of college faculty found that 66% were not aware of open textbooks and 15% only somewhat aware. Because introductory psychology is psychology's most popular course with 1–2 million students enrolled annually and almost 50% are community college students, we addressed this unawareness problem by providing analytical discussions of the viability of the open introductory textbooks presently available. We conclude that traditional textbooks are higher in quality, but open textbooks meet a specific market need.

Inflammatory mediators of trauma and sepsis transduce cellular events through cell surface receptors initiating intricate membrane and cytosolic reaction cascades that funnel through surprisingly few checkpoints in order to provoke a cellular response. As critical care surgeons, we can explore these cell signalling systems. The purpose of this article is to delineate the six known second messenger pathways relevant to surgical sepsis and trauma. Our comprehension of these signaling systems may offer us an opportunity to blunt post-traumatic cellular injury and promote a constructive response.


Superior performance of Back-gate-Controlled IGBT (BC-IGBT) by optimizing both front side and back side design has been demonstrated. Front side trench gate extrusion D<inf>T</inf>-D<inf>P</inf> (trench depth minus p-base depth) and back side p-collector dose N<inf>PC</inf> were varied to see their effects on the performance. Combining the increase of N<inf>PC</inf> and D<inf>T</inf>-D<inf>P</inf> with back gate control, significant reduction of V<inf>cesat</inf> (2.1 to 1.7V) was realized, while keeping E<inf>off</inf> unchanged. These results show that BC-IGBT is an attractive candidate for a high performance switching device.


ABSTRACT Electrically small, Hilbert fractal, near-field resonant parasitic (NFRP) antennas are reported and investigated in this paper. This type of electrically small antennas (ESAs) consists of Hilbert fractal curves as the NFRP resonators and small vertical monopoles as the driven elements. By offsetting the driven monopole off the centre position, good impedance matching can be easily realized. The current distributions on the fractal NFRP elements and the driven monopoles manifest that strong electric coupling could excite loop-mode currents along the Hilbert fractal NFRP structures, and thereby horizontal magnetic monopole patterns with broadside radiation property are realized. The results show that the 2nd-step evolution Hilbert fractal NFRP antenna witnesses an electrically size reduction of 25% compared to ka = 0.9622 of the square capacitively loaded loop (CLL) NFRP antenna, while maintaining its original broadside radiation. It is also demonstrated that there is a performance trade-off, i.e. higher fractal iteration orders leading to smaller resonant frequencies, narrower bandwidth and lower radiation efficiencies.


Computer systems are a pervasive aspect of daily life. From the smart phones we use to access our favorite websites, to the services those websites provide, to the computer systems that manage core infrastructure services (e.g., air traffic control, the power grid, or the stock market), there are very few aspects of a normal day not mediated by computer systems. Two byproducts of this integration are increased frustration when these systems don't work properly and corresponding appreciation for the value of dependable systems. The goal of my research is to build robust distributed systems that simply work despite the best, and worst, efforts of the environment. Building robust systems is challenging for multiple reasons. On the one hand, the definition of "works" is system dependent and frequently invokes a tension between performance and some notion of correct behavior. On the other hand, there are many environmental factors that can get in the way: crashed components, corrupted hardware, transient electromagnetic interference, delayed and corrupted messages, misconfigured servers, malicious attackers, disaffected sysadmins, selfish users, benign concurrency, changes in workload, . . . . My approach is based on a synergy between system building and theoretical work. To be confident that my systems work as advertised, I base my design and implementation efforts on solid theoretical foundations. To ensure that my theoretical foundations are relevant, I leverage the system building experience to develop new theoretical models and correctness conditions that better match the system deployment requirements. I have applied this methodology to a variety of applications in domains ranging from peer-topeer backup to live video streaming to scalable cluster file systems. In the process I have developed new fault models and built systems that are both more practical and more robust than previously thought possible. In the following I briefly overview of my previous work and future plans.1

W hile psychologically oriented social psychologists have utilized operant principles in their analyses of human behavior, social psychologists with sociological backgrounds have been reluctant o do so. Part of this reluctance has been due to the persistent belief that operant principles are germane to infrahuman behavior, but cannot fully explain human interaction. In response to this argument, heorists have attempted to clarify and formalize operant principles (Bijou and Baer, 1961; Burgess and Akers, 1966; McGinnis, 1970). While clarification and formalization of operant principles enhance the attractiveness of the operant approach for sociologists, the applicability of the approach to human interaction isnot enhanced.' It is suggested here that if operant theory is to be used to explain social behavior, then explicit attention must be given to certain assumptions germane to social interaction.2 The characteristics and assumptions of social interaction and the way in which these elements may be used in operant theory to make the model more applicable to human interaction are discussed below.

The internal rotational barrier heights of formamide and acetamide were studied by ab initio molecular orbital calculations using several basis sets up to 6-311 G (2d,2p) with electron correlation correction. The calculated barrier heights depended on the basis set used. The calculated barrier heights with the MP3 (Moller–Plesset 3rd order perburbation) electron correlation correction were decreased by the augmentation of polarized functions by as much as 5–6 kcal mol–1. Further augmentation of multiple polarized functions and diffuse functions had little effect on the calculated barrier heights. The calculated barrier heights using polarized basis sets were decreased by the incorporation of electron correlation by as much as 1–2 kcal mol–1 from the values obtained by HF method. The calculated barrier heights of formamide and acetamide using polarized basis sets with electron correlation correction were 14.5–15.4 and 12.5–13.2 kcal mol–1, respectively. Whereas these barrier heights were 1–8 kcal mol–1 lower than the experimental values measured in the liquid phase, the calculated values were close to the barrier heights measured in a polystyrene matrix. Zero point and thermal vibrational energies of formamide were calculated at HF/6-31 G* level. The calculated vibrational energy correction for the barrier height was only –0.75 kcal mol–1.


This research discusses temperature and humidity monitoring systems using wireless Xbee module-based microcontrollers carried out in hydroponic plants. Microcontroller has functions for storing programs in electronic circuits. Xbee has a function for wireless communication devices that work on the 2.4 Ghz frequency with a range of 1500 meters. The technique used in this study used two Xbee modules, which are used as the sending node and receiving node. The sending node is as the controller. It used the Arduino module which is connected to the DHT 11 sensor as input and Xbee as the sender. The receiver node as a data processor consists of Xbee module connected to the Arduino module and LCD to display data. In this research, the results of comparison of DHT11 sensors with a Thermo-Hygro measuring device with an average temperature error of 0.75°C and 3% humidity. The results of testing the four DHT11 sensors outside the room get an average value of 28.94° C with humidity test results in the room 29.14° C and 58.86% with an Xbee range of 70 meters. Wireless design of temperature and humidity monitoring systems based on Xbee communication is successfully implemented in hydroponic plant cultivation.


This study was carried out during the two successive seasons of 2013/2014 and 2014/2015 on five established football (soccer) green fields (yards) in the urban and suburban areas of Mansoura City, Dkahlia Governorate, Egypt. It aimed to compare the effects of different fertilization programs on the performance and quality of the lawn (turfgrass) of the five yards (fields). Five football fields were chosen based on similarity of basic specifications namely; a standard field size (65-70 m in width and 100110 m in length), planted using sods of Paspalum vaginatum Sw lawn (turfgrass), sandy soil (sand thickness of 15-20 cm over 30 cm layer of pebble stones), all have existing drainage systems, and no soil aeration were carried out in any of the fields' maintenance programs. The football yards (fields) were Mansoura Stadium, Mansoura University and El-Shaab stadiums (located in Mansoura city) in addition to Beny Ebeid and Secondary Beny Ebeid stadiums (located in Beny Ebeid town). Data of maintenance programs were collected from the maintenance managers of different stadiums. In addition, measurements for the visual color and quality in addition to total chlorophyll contents (mg/g fresh clipping sample), and N, P and K percentages in the clipping samples of the turfgrass (lawn) of the five fields were carried out during the two seasons.The obtained results showed that increasing number of N applications (doses) combined with reasonable low quantity each application (dose) had a positive effect on color and quality of the turf in addition to its chlorophyll content. The results also supported the need of adding phosphorus to the turfgrass, but to a much lesser degree than the need of nitrogen. Based on the results of both seasons, Mansoura University Stadium fertilization program was the best to achieve better visual color and quality of the turfgrass in addition to total chlorophyll contents (mg/g fresh weight) of the clippings. This program comprised of five applications (doses) of a mixture of urea and potassium nitrate fertilizers (50% each); each dose containing 0.62 Kg N /100 m2 of the grass field during spring and summer months (March – October); summing up a total of 3.12 Kg N / 100 m2 / year, in addition to two applications of calcium super phosphate ; each containing 0.34 Kg P /100 m2 of the grass field during fall and winter months (November – February) summing up a total of 0.69 Kg P / 100 m2 of grass.


The composition of the essential oil from a Thymus vulgaris L. type growing wild in northern Italy was determined by GC and GC-MS. Forty-four components of the oil were identified, monoterpenes being the most abundant (about 80%). The biogenetic sequence γ-terpinene p-cymene thymol probably defines the chemotype. The effect of environmental conditions over the two consecutive trial years was evaluated with respect to the quali-quantitative composition of the essential oils and some agronomic parameters.
