Organizations in the 21st century require managers who possess the ability to create employee satisfaction through the right leadership style. Boleslaw (2009) observed that some senior managers believe leadership is about power-holding to manipulate and control the employees. Such leadership style may cause employees' dissatisfaction with their jobs and affect the performance of organizations operating in the competitive business environment. A quantitative correlational research study was conducted to investigate the relationship between leadership style of the senior managers and job satisfaction and commitment of the middle managers working at the corporate headquarters of a communications company in Atlanta, Georgia, USA. In the research study, 166 middle managers of the organization were involved. The middle managers implement organizational strategies, oversee departments within the organization, and report to their respective senior managers. The senior managers included the chief executive officers and the division heads who create strategies for the middle managers to implement. The independent variable examined in the quantitative correlational research study was the leadership style of the senior managers measured with the attributes of transformational, transactional, and laissez-faire leadership styles. The dependent variable was the job satisfaction of the middle managers and their commitment to the organization. The research instruments used to collect data for the current research study were the MLQ Rater Form 5X-Short to investigate leadership style, Job in General Survey (JIG) instrument to evaluate job satisfaction and Organizational Commitment Questionnaire (OCQ) to measure employee commitment to their organization. A demographic questionnaire was developed for the research study to describe the participants and analyze sub-groups of the participants. The statistical analysis SPSS Version 20.0 was used to collate data and calculate descriptive statistics such as mean, standard deviation, minimum, and maximum for each leadership style and overall job satisfaction. Descriptive statistics, Pearson correlation coefficient, the analysis of variance (ANOVA), and multiple regression analysis were used for the data analysis. Analysis of the data found that transformational leadership style has a positive correlation on employee job satisfaction and employee commitment. A higher level of job satisfaction and employee commitment for employees who had managers who exhibited transformational leadership was observed. Analysis of the demographic variables found that demographic variables moderated the relationship between leadership style of the senior managers and job satisfaction of the middle managers. The study found that employees, most especially, middle managers of communications industry preferred their senior managers to exhibit more of transformational leadership features, less of transactional leadership, and little or no of laissez-faire leadership styles. Accordingly, leaders in organizations can use the findings from the quantitative correlational research study to enhance positive changes such as increased job satisfaction, organizational commitment, unity of purpose, and organizational citizenship behaviors (OCBs) in their organizations.


SUMMARY Re-examination of Dinantian coral assemblages from the lowest beds exposed in the mid-1930's in Haw Bank Quarries, and in Holywell Bridge railway cutting, Skipton, West Yorkshire, indicates that they are of late Courceyan age. Correlations with coral assemblages from the South-Western Province and from Ireland are suggested. Sychnoelasma hawbankense sp. nov., a solitary rugose coral, is described from Haw Bank Quarry and other localities in the Skipton Anticline, as well as from Bristol, the Mendip Hills, Gower, and the Dublin Basin, Ireland. The records show that this species has a limited stratigraphical range from late Courceyan to Chadian. A phylogenetic sequence for some species of Sychnoelasma is proposed.


In the face of increasing power grid monitoring information, existing data is stored in different databases. There is an urgent need to unify multi-source data specifications into the same database effectively. The power grid monitoring field introduces knowledge graphs to store associated massive data. However, the research on the efficient fusion of multi-source data is still in its infancy. In order to solve the problem of low fusion accuracy of existing entity alignment methods, this paper proposes a new idea based on the fusion of domain ontology vocabulary on the basis of a similarity comparison algorithm. By dividing some entities into different categories and then comparing and categorizing the remaining entities, the standardization of fusion is enhanced, and the possibility of misclassification is reduced. Finally, after a comparison of calculation examples, the results show that the entity alignment method in the field of power grid monitoring based on the ontology vocabulary proposed in this paper improves the accuracy of fusion compared with the previous similarity algorithms and provides new ideas for the further development of multi-source data fusion in the field of power grid monitoring.


In this study, the successive approximations method has been applied to investigate the solution for the linear bigeometric Volterra integral equations of the second kind in the sense of bigeometric calculus. The conditions to be taken into consideration for the bigeometric continuity and the uniqueness of the solution of linear bigeometric Volterra integral equations of the second kind are researched. Finally, some numerical examples are presented to illustrate successive approximations method.


This thesis studies the problem of supervised learning using a family of machines, namely kernel learning machines. A number of standard learning methods belong to this family, such as Regularization Networks (RN) and Support Vector Machines (SVM). The thesis presents a theoretical justification of these machines within a unified framework based on the statistical learning theory of Vapnik. The generalization performance of RN and SVM is studied within this framework, and bounds on the generalization error of these machines are proved. In the second part, the thesis goes beyond standard one-layer learning machines, and probes into the problem of learning using hierarchical learning schemes. In particular it investigates the question: what happens when instead of training one machine using the available examples we train many of them, each in a different way, and then combine the machines? Two types of ensembles are defined: voting combinations and adaptive combinations. The statistical properties of these hierarchical learning schemes are investigated both theoretically and experimentally: bounds on their generalization performance are proved, and experiments characterizing their behavior are shown. Finally, the last part of the thesis discusses the problem of choosing data representations for learning. It is an experimental part that uses the particular problem of object detection in images as a framework to discuss a number of issues that arise when kernel machines are used in practice.

Moore's law states that computing performance doubles every 18 months. While this has held true for 40 years, it is widely believed that this will soon come to an end. Quantum computation offers a potential solution to the eventual failure of Moore's law. Researchers have shown that efficient quantum algorithms exist and can perform some calculations significantly faster than classical computers. Quantum computers require very different algorithms than classical computers, so the challenge of quantum computation is to develop efficient quantum algorithms. Cybernet is working with the Air Force Research Laboratory (AFRL) to create image processing algorithms for quantum computers. We have shown that existing quantum algorithms (such as Grover's algorithm) are applicable to image processing tasks. We are continuing to identify other areas of image processing which can be improved through the application of quantum computing.


Perioperative neuropathic pain is under‐recognized and often undertreated. Chronic pain may develop after any routine surgery, but it can have a far greater incidence after amputation, thoracotomy or mastectomy. The peak noxious barrage due to the neural trauma associated with these operations may be reduced in the perioperative period with the potential to reduce the risk of chronic pain.


on restorative justice practices and development of a national concept of J4C; a national assessment on adolescents' mental health was conducted with commitment from the Government to establish a roadmap for action; and greater attention to increase online safety and to integrate 21st century skills into system responses. Involvement of more than 8,000 volunteers from across Belarus to the 2nd European Games accelerated youth participation and volunteering opportunities. The EuroGames volunteers grew to over 150 for the Games with participation in regions across Belarus. On this momentum, the CO continued to reach out to volunteers and has established over 200 'regular' volunteers (from 16-24 years) and more than 500 signed up for volunteering. At the same time, the volunteers are participating at different levels – being located across the country and not just in the capital. Volunteers participate in different events and have started to also become more involved in programme implementation. In 2020, the CO is taking steps to further systematize it volunteering process and involve in more regular programme processes.


Tracheoesophageal fistula is an abnormal communication between trachea and esophagus 1 . Acquired tracheosophageal fistula are a rare complication of mechanical ventilation occurring in 0.5% of intubated patient after 30 days of intubation 2 .Prolonged endotracheal intubation remain most common cause 1 . The incidence decreased after the use of low pressure and high volume endotracheal cuffs, but the intensive care units continue to provide such cases. We reported a case of tracheoesophageal fistula after prolonged intubation. Though, rare complication , high suspicion is necessary to accurately diagnose the disease in patient with history of prolonged intubation. Introduction Tracheoesophageal fistula (TOF) is an abnormal Connection between trachea and esophagus 1 . It may be congenital and acquired. congenital TOF are diagnosed following birth or during infancy 2 . Acquired TEF is an uncommon complication. Acquired TEF mostly occur secondary to several malignancies ( i.e esophageal cancer ), infection, ruptured diverticula and injuries. However, Endotracheal intubation remains the most common cause with the incidence of < 1%, first reported by D'Avignon ( 1956) and Mounier – kuhn (1958). 3 The clinical manifestation differ, depending on the patient's respiratory status .cough following swallowing is the chief presentation in non ventilated patient. Air leak even with hyperinflated cuff and abdominal distension is the chief presentation in ventilared patient. Bronchoscopy, esophagogastroscopy and computed tomography are investigation of choice 3 . Often the diagnosis is made early but the mortality remains high if not treated. We present a 37 year old male case of tracheoesophageal fistula following prolonged intubation for 45 days. Case Report 37 year alcoholic male patient presented with hematemesis, malena, one episode of generalized abnormal body movement and transient loss of consciousness and was diagnosed with chronic alcoholism with withdrawal seizure with upper GI bleed due to oesophageal varices admitted in medicine ward. The patient was intubated on day 3 of admission and put on mechanical ventilation in respiratory ICU. Patient was remained intubated for 20 days. Treatment continued and enteral feed through ryles tube were given. Patient was extubated on day 20 th as patient chest become clear and other parameter were improved. Next day after extubation, patient complained of http://jmscr.igmpublication.org/home/ ISSN (e)-2347-176x ISSN (p) 2455-0450 DOI: https://dx.doi.org/10.18535/jmscr/v9i6.06

For surgeries which require general anesthesia, airway management is imperative. Difficult airway, which inhibits proper intubation, can be fatal. As such, pre-operative airway assessments are conducted by clinicians to determine the ease of intubation as well as to identify patients with difficult airway. To improve the process, artificial intelligence (AI) methods can be employed to predict such difficult airway situations so that suitable preparations can be made beforehand. However, due to the need for explainability of AI models required by healthcare regulations, typical black box models which work best with most data-driven AI methods cannot be used. Therefore, in the current work, a machine learning model has been established to predict the specific medical facial landmarks that are currently used by clinicians. These include the eyes, mentum, thyroid notch, suprasternal notch, forehead, tragus and radix. The model is based on convolutional neural network and a practical facial landmark detector concept. Furthermore, k-fold cross-validation sampling and the Adabelief optimizer have been utilized. The model prediction results display accurate prediction of the features, with the testing loss exhibiting good stability and maintaining well below 0.01 throughout. Attributed to that, the current model can lead to meaningful diagnosis of difficult airway during airway assessments.


We searched the IRAS database at the positions of pulsars to see if they are associated with FIR sources, as might be expected if some pulsars possess preplanetary disks. There are 13 IRAS sources from the Point Source Catalog within 1 arcmin of nearly 500 radio pulsars. While this does not represent an enhancement over the number of chance coincidences, we argue that several are in fact associated with pulsars.


The C content in high strength steel must be controlled at a lower level for the good weldability. However, the lower level of C content will reduce the C partitioning efficiency and influence the stability of retained austenite, which leads to the decrease of the product of tensile strength and elongation of high strength steel. A novel preparation mechanism of high strength steel is to employ some kind of substitutional alloying elements, for example Mn, instead of C to partitioning to enhance the austenitic stability, which would not remarkably reduce the weldability of the steel. One low alloy C-Si-Mn steel was used in present work. The Mn partitioning behavior and its effect on the stability of the retained austenite and the mechanical property were studied by means of intercritical annealing, subsequent austenitizing, then quenching and partitioning process(IQP). The results show that in the process of intercritical annealing at 760 ℃, by extending the annealing time, austenite volume fraction increases gradually until it reaches the saturation, meanwhile the Mn partitioning behavior occurs and Mn content increases gradually from ferrite to austenite until it reaches the chemical potential balance in two phases. The sample is heated to 930 ℃ for 120 s, then rapidly quenching to 220 ℃, the carbon diffuses from martensite to austenite phase in the process of partitioning. After IQP process, the tensile strength of experimental steel is 1310 MPa, elongation up to 12%, the product of strength and elongation up to more than 15000 MPa· %. The steel only contains a small amount of retained austenite by only C partitioning after traditional QP process, while the steel contains more Mn- rich retained austenite after IQP process. Hence, the content and stability of retained austenite of steel can be improved significantly, which enhance the formability at room temperature.


Tobacco is a harmful addictive product with special market performance.The price elasticity of demand for tobacco and its elasticity of income are different from normal market.The regulation for tobacco industry focuses on decreasing rather than promotion as applied in normal industries.The tobacco market in China is quite different not only from developed countries but also other developing countries.The regulation of tobacco in China should not ignore precedent international lessons while taking into account of the specificity of Chinese tobacco market.The policy black hole in the tobacco market of China must be considered as one of the most important preconditions in the policy framework.The balance between efficiency and cost of regulation would be achieved with the goal of social justice accordingly.


We derive upper and lower bounds at the point at which the average outgoing quality limit (AOQL) of an attributes acceptance sampling plan is achieved. Using a simple average of these bounds to approximate the ordinate of the AOQL, we develop an accurate, closed-form approximation to the AOQL. The bounds and approximation show how the parameters of a sampling plan affect the AOQL and can be used to study the behavior of the AOQL and other measures of the plan's performance.

Violence is a social economic phenomenon in the world of transcendental civil social order, a determinant of the social, political, and it is a global social scourge that affects substantial magnitudes basic legal rights of human beings that have weakened in different areas of the person's psychological, physical, sexual and economic environment.
According to the United Nations, 6 out of 10 women in Ecuador suffer from violence, while 1 in 5 women in the world is a victim of rape or attempted rape.
In Ecuador, 61% of women have experienced some form of violence. 1 in 4 women has experienced sexual violence. However, psychological violence is the most recurrent form of gender violence in the country, with 53.9 % of cases. And el76 % of women have been raped by their partner or ex-partner, most of the time, the crime or abuse is not committed on the street or at work, but on the contrary , it happens behind closed doors , in the private space: the house, privacy and home.
These are the main data conclude the First National Survey of Family Relations and Domestic Violence against Women.
According to a report by Amnesty International, at least 1 in 3 women has been beaten, have forced the sex or has suffered some other kind of abuse.

The statistics are indisputable referenced scenario of gender inequality, existence of degrading behaviors that affect directly or indirectly the integrity of the family and of women in particular, who continues to experience discrimination in different areas of public and private participation;
While the evolution of public policy in the prevention of violence in all its forms has been positive, gradually have generated projects through interagency cooperation aimed at strengthening from the various priorities the protection of the rights of individuals, prevention affirmative actions have led to greater recognition of the prerogatives of the people and therefore we can say that there are significant advances in respect for and protection of personal integrity that just includes the right to have all people to live in an environment free from violence in all its forms.
But domestic violence and gender is a conflict of structural order that requires continuous processes of awareness, training and cooperation to build new patterns of behavior and cultural patterns that ensure gender equality, understood as the right of men and women to participate and act on equal conditions in political, economic and family processes.


Studies have found that a small scale of operations could limit the firm performance since they do not enjoy economies of scale. Since the microfinance industry is focused on provision of financial services to the poor, performance is measured both from a social as well as financial perspective. As firms increase their scale of operations, their social performance needs to be on par with their financial performance. To measure the effect of scale on performance, we use data from the Microfinance Information Exchange (MIX) market consisting of 245 Microfinance Institutions (MFIs) covering a period of 21 years from 1999 to 2019. The dependent variables are outreach, efficiency, and financial performance. The control variables are age and the regulatory status of the firm. We find that while factors like financial performance, client retention, and measures of operational efficiency are dependent on scale; they come at the cost of outreach. The pursuit of economic goals by large MFIs seems to hamper their ability to reach the poorest and/or most needy clients, implying mission drift. This study thus draws the attention of policy makers to the importance of supporting small MFIs to survive and continue to address the social goals of MFIs.


The authors compute exactly the eigenvalues of atomic clusters of arbitrary size with a simple cubic structure in the tight-binding approach (LCAO), including surface effects. To represent the electronic structure of the hypothetical metallic clusters they consider well separated and p states. They find strong deviations from the corresponding states of the bulk cubium where the number of particles is of the order of 104 or less (R<or approximately=50 AA): new states appear near the top of the bands and states disappear near the bottom of the bands. This produces an upward shift of the Fermi level and of the mean energy with decreasing size and an asymmetric and deformed shape of the density of states. Effects of the geometrical shape of the cluster and of the environment are also considered. They discuss the relevance of their results on the interpretation of recent photoemission experiments on small metallic clusters.

The paper focuses on the experimental and theoretical study of plastic deformation instability and localization in materials subjected to dynamic loading and high-velocity perforation. We investigate the behavior of samples dynamically loaded during Hopkinson-Kolsky pressure bar tests in a regime close to simple shear conditions. Experiments were carried out using samples of a special shape and appropriate test rigging, which allowed us to realize a plane strain state. Also, the shear-compression specimens proposed in [1] were investigated. The lateral surface of the samples was investigated in a real-time mode with the aid of a high-speed infra-red camera CEDIP Silver 450M. The temperature field distribution obtained at different time made it possible to trace the evolution of plastic strain localization. Use of a transmission electron microscope for studying the surface of samples showed that in the regions of strain localization there are parts taking the shape of bands and honeycomb structure in the deformed layer. The process of target perforation involving plug formation and ejection was investigated using a high-speed infra-red camera. A specially designed ballistic set-up for studying perforation was used to test samples in different impulse loading regimes followed by plastic flow instability and plug ejection. Changes in the velocity of the rear surface at different time of plug ejection were analyzed by Doppler interferometry techniques. The microstructure of tested samples was analyzed using an optical interferometer-profilometer and a scanning electron microscope. The subsequent processing of 3D deformation relief data enabled estimation of the distribution of plastic strain gradients at different time of plug formation and ejection. It has been found that in strain localization areas the subgrains are elongated taking the shape of bands and undergo fragmentation leading to the formation of super-microcrystalline structure, in which the size of grains is ~300nm. Rotational deformation modes give rise to the high angular disorientations of grains. The development of plastic shear instability regions has been simulated numerically. For this purpose, we use a recently developed theory, in which the influence of microshears on the deformation properties of materials has been studied by the methods of statistical physics and thermodynamics of irreversible processes. The results of theoretical and experimental studies suggest that one of the mechanisms of the plastic shear instability and localization of plastic strain at high-velocity perforation is related to structural and kinetic transitions in microshear ensembles.

Like many other countries, Kazakhstan has committed to carbon neutrality but is burdened by a fossil fuel-dependent economy that is particularly vulnerable to climate change. The net impact of various policy, technology, and business innovations aimed at transitioning to a greener economy are limited by the knowledge and behaviors of the populace. Integrating environmental education into the schooling system is underway but progress on behavioral change is glacial. Gamification and inquiry-based learning are transformative pedagogical tools that leverage students' natural creativity to reinforce fundamental concepts while encouraging deeper engagement. This article describes "Save Tuba," a mobile game application designed for second through fifth grade students to help them explore environmental issues and develop sustainable behaviors. Children build an emotional connection with Tuba, a saiga antelope whose natural habitat on the vast Kazakh steppes is threatened by humans, as they embark on a series of exciting and meaningful adventures. The article discusses the app's creation journey, narrative structure, pedagogical foundations, human-centered design processes, and curricular content.

Hallervorden-Spatz syndrome is a rare neurodegenerative disease, related to mutations in a gene located on chromosome 20p13. Hallervorden-Spatz syndrome is characterized by iron accumulation in the basal ganglia, which leads to variable neurologic manifestations. It is reported the case of a 6 years old male patient, with history of neuro psycho motor development involution noticed since 1 year and 5 months of age and progressive development of dystonia, mostly on upper limbs and neck. Brain Magnetic Resonance Imaging (MRI) revealed bilaterally symmetric signal changes in globus pallidus and in the posterior limb of the internal capsule, findings that suggest neurodegenerative disease with iron accumulation or metabolic disease.


Introduction: Direct laryngoscopy is associated with sympathetic stimulation and altered hemodynamics. A long intubation time may result in a greater in stress response. Alternative techniques using video laryngoscopes have been developed that do not require direct vocal cord visualization and may decrease the hemodynamic response. This study aimed to compare the difference between hemodynamic changes and intubation time with Airtraq video laryngoscope and conventionl Macintosh direct laryngoscope.
Methods: A prospective randomized comparative study was conducted involving 100 adult patients who were undergoing elective surgeries under general anesthesia and endotracheal intubation. The patients were randomly assigned to group V (Video laryngoscope) or group D (Direct laryngoscope). In addition to the baseline vitals and vitals at various time intervals, intubation time was also recorded. We considered a difference in Heart Rate and Mean Arterial pressure of 20% to be clinically significant and statistical significance was p-value <0.05.
Results: Significant difference was found in heart rates immediately after laryngoscopy (110.40 vs. 105.02 beats/minute; p<0.01) and 1 minute after intubation (109.30 vs. 106.20 beats/minute; p<0.01) with attenuation seen in video laryngoscopy group. Blood pressures were similar in both the groups at all times. Time for intubation was prolonged in video laryngoscopy group than that for direct laryngoscopy group (26.54 vs. 22.80 seconds; p<0.05). There were no adverse events associated with either of the techniques.
Conclusions: The Airtraq video laryngoscopy resulted in lesser change in heart rate and longer intubation time. However, clinical impact of such a difference seemed to be insignificant.

Nineteen new white maize inbred lines were top crossed with two testers i.e.; Sd. 7 and Sd. 63 at Gemmeiza Research Station in 2017 growing season. The resulted 38 crosses in addition to three commercial check hybrids i.e. SC10, SC128 and SC 2031 were evaluated at Gemmeiza and Sids Agriculture Research Station Farms during 2018 growing season. Data were recorded for the following traits: days to 50% silking, plant height, ear height and grain yield. Analysis of variance of crosses and their components, lines, testers and lines x testers showed highly significant differences for all traits, except lines x testers for days to 50% silking. σ2GCA was larger than σ2SCA for all traits.

With the current economic expansion in the United States now beginning its third year, the persistence of federal government budget deficits on a historically unprecedented scale has clearly become the chief distinguishing characteristic of this business cycle both economically and politically. The budget for the 1978 fiscal year submitted to Congress by President Reagan acknowledges that, after a small improvement in 1984, the 1985 deficit will exceed even the record $208 billion mark posted in the immediate post-recession environment of 1983. More important, the President's new budget indi cates that even with a strong economy, and even after $50 billion of proposed spending cuts, the 1985 deficit will show no improvement over 1984.

One of the large problems facing engineers in the economic analysis of public projects is the estimation of comfort and convenience costs and of lost wage costs. Comfort and convenience costs have generally been either ignored or treated as a linear function of the trip delay time; wages lost to tardiness have also generally been assumed to be linear when they have been considered at all. But personal experience argues against the idea of a linear comfort and convenience cost-except in unusual circumstances, short delays in the completion of a trip have negligible actual costs. Similarly the wage loss due to tardiness is recognized to have a zero value when the tardiness is below some threshold value, and this threshold value is recognized in most union contracts. This paper treats the problem of calculating comfort and conveninece costs analytically and proposes a probability distribution that is easily used to estimate the value per person trip of both such costs. This technique is then applied to cost estimation where the delay is caused by snow and ice on a roadway. /Authors/


Volvulus of the sigmoid is the most common cause of intestinal obstruction in pregnancy, untreated it evolves towards the intestinal ischemia and the perforation [1]. We report the case of a 38-year-old patient in the third trimester of pregnancy admitted for sigmoid volvulus. Endoscopic devolvulation has been tried with failure. At surgical exploration, the sigmoid volvulus was necrotic. The sigmoid volvulus was resected and Hartman's colostomy was performed. The purpose of this publication is to show the therapeutic difficulties of this rare association (pregnancy and volvulus).

The invention relates to a terahertz wave detection device. The terahertz wave detection device comprises a sample table, a terahertz wave radiation source, a first off-axis elliptical mirror and a second off-axis elliptical mirror, wherein a sample to be detected is arranged on the sample table, and the sample table is arranged on a common focal point of the first off-axis elliptical mirror and the second off-axis elliptical mirror; the terahertz wave radiation source is arranged on the other focal point of the first off-axis elliptical mirror and is used for emitting terahertz waves; the first off-axis elliptical mirror is used for focusing incident terahertz waves to the sample table; one focal point of an ellipse of the second off-axis elliptical mirror coincides with the other focal point of an ellipse of the first off-axis elliptical mirror, and the second off-axis elliptical mirror is used for reflecting and then converging the converged terahertz waves to the other focal point of the ellipse of the second off-axis elliptical mirror. According to a principle that the terahertz waves emitted from one elliptical focal point are converged to the other elliptical focal point after being reflected by the elliptical mirrors, two focusing processes are finished by the two elliptical mirrors, the terahertz waves carrying information of the to-be-detected sample are converged to a detector, and thus the structure of the terahertz wave detection device is simplified.

A novel fuzzy neural network (FNN) model for invariant pattern recognition is presented that combines fuzzy set reasoning and artificial neural network techniques. The presented FNN consists of three blocks: fuzzifier, fuzzy perceptron, and defuzzifier. It fuzzifies the input patterns and trains the interconnection weights according to membership functions instead of traditional binary values. The proposed FNN has been applied to 2-D binary-image pattern recognition under shift and some other types of distortions. In comparison with the classical multilayer perceptron, the FNN possesses a higher recognition rate and is more robust to input distortions.


This paper describes a new architecture for high-resolution digital PWM (DPWM) generator used in digitally-controlled DC-DC converters, PWM time resolution is determined by the difference between two (or more) gate delays, while that of conventional DPWM circuits is determined by gate delay itself. The proposed DPWM circuit can achieve fine time resolution with small circuits, and has low power consumption. We have also developed a systematic design method for this DPWM circuit based on the extended Euclidean algorithm. A design example that achieves 10 ps time resolution for 80 ns cycle time (i.e. 13-bit resolution) is shown to demonstrate the effectiveness of the proposed DPWM architecture.


New features of the twisted dusty plasma modes and associated instabilities are investigated in permeating plasmas. Using the Vlasov–Poisson model equations, a generalized dispersion relation is obtained for a Maxwellian distributed plasma to analyse the dust-acoustic and dust-ion-acoustic waves with finite orbital angular momentum (OAM) states. Existence conditions for damping/growth rates are discussed and showed significant modifications in twisted dusty modes as compared to straight propagating dusty modes. Numerically, the instability growth rate, which depends on particle streaming and twist effects in the wave potential, is significantly modified due to the Laguerre–Gaussian profiles. Relevance of the study to wave excitations due to penetration of solar wind into cometary clouds or interstellar dusty plasmas is discussed.


【Biocontrol activity of five strains of selected rhizo-bacteria were tested in tomato against bacterial wilt caused by Ralstonia solanacearum. After root bacterization the plants were grown in a perlite-hydroponic system. Upon challenge inoculation with the pathogen, all of the rhizobacterial strains efficiently suppressed the bacterial wilt in tomato in various rates, at maximum by the strain, Bacillus vallismortis strain EXTN-1. While the percent of infected plants in the non-bacterized control plants were 95%, it was only 65% in plants pre-treated with EXTN-1. It was also demonstrated that the movement of R. solanacearum within the stem was significantly hampered when the plants were root bacterized. As EXTN-1 has no antagonistic properties against R. solanacearum, the bacterial wilt was probably suppressed by a mechanism other than antibiosis. Previously, the strain had been proven to produce an efficient elicitor for inducing systemic resistance in many crops. As the present study confirmed that EXTN-1 has the ability for reducing the pathogen spread in tomato, the strain could be effectively used as a potential biocontrol agent against bacterial wilt.】

Summary - A microparticle-enhanced nephelometric immunoassay of bovine immunoglobulins G is reported. lt is based on the nephelometric quantification of the competitive immunoagglutination of covalently coated microparticles. This new immunoassay is easy to perform (1-step, no sample pretreatment, no washing or phase separation), fast (1 h at most), sensitive (8 Ilgl1 of immunoglobulins G significantly detected in the reaction mixture), accu rate (linear recovery of immunoglobulins G in overloaded milks) and reproducible (CVs from 2.3-10% in within- and between-run precision studies). The potential of this microparticle-based immunoassay ls discussed with regard to the other quantitative immunoassays (radial immunodiffusion and convention al immunonephelometry in parneular) used in the determination of milk immunoglobulins G.


This paper deals with a breadboard of CO2 laser Doppler rangefinder based upon the "chirp pulse compression" technique, and realized in common by Thomson-CSF and Cilas.

In this paper, the design and flight testing of a H∞ Stability Augmentation System to improve the lateral handling qualities of a remotely controlled Unmanned Air Vehicle is presented. The problem of decoupling the roll response and the sideslip response using model-matching approach is considered along with control sensitivity minimization. In contrast to the conventional two degree of freedom controller design using model-matching approach, a single degree of freedom controller is designed in this paper for ease of implementation. Gain scheduling is avoided by designing the controller at a single flight condition that robustly stabilizes the closed loop system and retains performance characteristics at all flight conditions. For the purpose of determining the design point, two approaches, namely worst-case analysis and proximity of plant models is performed at all flight conditions. Robustness of the closed loop system to both structured and unstructured uncertainties at all flight conditions is examined through mu analysis. Final flight test results are compared with offline nonlinear simulations.

Simple expressions are given for the mean delay, mean waiting time, and mean busy period length in a multiplexer. A large class of possible data streams is considered. For example, data streams with active periods having a general distribution are permitted, and the traffic rate during the active periods can be random. Data can also arrive in batches. The output stream of the multiplexer again falls into the class. The exact formulas allow evaluation of the error in approximations such as a heavy traffic diffusion approximation. Both continuous-time and discrete-time models are treated. The Pollaczek-Khinchine formula for the mean amount of work in an M/G/1 queue is retrieved as a limiting case.<<ETX>>


Two simple iterative desmearing procedures – the Lake algorithm and the Van Cittert method – have been investigated by introducing different convergence criteria using both synthetic and experimental small-angle neutron scattering data. Implementing appropriate convergence criteria resulted in stable and reliable solutions in correcting resolution errors originating from instrumental smearing, i.e. finite collimation and polychromaticity of the incident beam. Deviations at small momentum transfer for concentrated ensembles of spheres encountered in earlier studies are not observed. Amplification of statistical errors can be reduced by applying a noise filter after desmearing. In most cases investigated, the modified Lake algorithm yields better results with a significantly smaller number of iterations and is, therefore, suitable for automated desmearing of large numbers of data sets.

The fruits of the caja-mangueira (Spondias dulcis Parkinson), Present high potential for the market of fresh fruits, and also desirable characteristics for the processed one, due to their sensorial and nutritional characteristics, being presented with good perspectives of cultivation and commercialization of in order to allow the development of the region. The objective of the present study was to characterize caja-mangueira fruits harvested at commercial maturity (totally yellow color) from the microregions of the Brejo Paraibano (BP), Joao Pessoa (JP) and North Coast (LN), State of Paraiba, Brazil. A completely randomized design with two treatments (Microregion) was used, with 15 fruits, each fruit one repetition for physical characterization and three replicates of 150 g of pulp for the physical-chemical characterization. The characterization of the fruits was carried out through 11 evaluations of: length (L), diameter (D), firmness (F), fruit weight (FW), yield of pulp (YP), percentage of bark (PB), percentage of core (PC), pH, total soluble solids (TSS), total titratable acidity (TTA) and SS/TTA (ratio). The physical and physicochemical characteristics of the fruit from the North Coast microregion indicate that these can be used both for the consumption of fresh fruits and for industrialization. The results of the analysis of variance showed the existence of significant simple linear correlations between the physical and chemical characteristics analyzed, indicating the existence of characters such as fruit size or soluble solids content to estimate production, selection and fruit quality parameters of the caja-mangueira.


Some fungi, isolated from soil and pasture grasses, have been examined in investi,gations relating to facial eczema disease of sheep. Cultures of fungi were submitted to Ruakura Animal Research Station for the "beaker test", •vhich had frequently been found to give positive results •vith toxic· grass. A positive test was given by a high-sparing strain of Sporidesmium bakeri Syd., isolated from pasture grass. Negative tests were given by the other species. Eleven fungi (six species), including a strain of S. bakeri, were grown on modified Czapek-Dox and Raulin-Thom media and fed to guinea pigs. Examination of livers at Wallaceville Animal Research Station showed no symptoms characteristic of the facial eczema toxin associated with grass. A high-sparing strain and two other strains of S. bakeri were later cultured on a number of media and the macerated fungal felts and culture fluids were sent to Ruakura Animal Research Station for animal feeding experiments. Some of these cultures pro-· duced in the guinea pig symptoms associated with facial eczema disease.

In this paper, we aim at the optimal use of the scarce energy collected by a node powered by human energy harvesting in order to improve the provided Quality of Service (QoS). To achieve this goal, we have developed a Power-QoS control scheme, called PEH-QoS. PEH-QoS is composed of three sub-modules that interact with each other in order to make optimal use of energy and get the best possible QoS. The scheme intends to ensure that a node can both capture/detect the medical events and transmit the respective data packets efficiently. One of the main features of our mechanism is that only useful data sequences are transmitted, discarding data packets that have lost their clinical validity (i.e., out of date). Extensive simulations have been conducted in order to evaluate the behavior of PEH-QoS in a typical medical node under energy harvesting conditions.

Homogeneous catalysis offers advantages over heterogeneous catalytic methods in that all catalyst molecules are available for the substrate, and the catalyst can be tailored to the desired chemical transformation by choosing (designing) the proper ligand environment. In most cases, however, industry uses heterogeneous catalysts because (in addition to their high activity and selectivity) catalyst–product separation poses no serious problems. A successful way of heterogenization of homogeneous catalysts is the separation of the reactants (products) and the catalyst into immiscible liquid phases (liquid multiphase catalysis).

This article reviews biphasic catalysis with homogeneously (molecularly) dispersed catalysts. Attention is focused on liquid–liquid biphasic systems, containing all the reactants and the catalyst(s) in dissolved state. Such biphasic systems are built up of two or more solvents with limited mutual solubility. Aqueous–organic and organic–organic (including also fluorous) biphasic systems have been studied for long; however, the use of biphasic reaction mixtures designed by using fluorous solvents, ionic liquids, and supercritical gases in combination with each other or with appropriate aqueous or organic solvents has been rapidly developing recently. The properties of such systems together with the need of special ligand design or modifications are discussed, and their use is illustrated by describing typical reactions (hydrogenation, hydrogen transfer, hydroformylation, hydrocarboxylation, carbonylation, alkene metathesis, dimerization, polymerization, and other CC coupling reactions).

The University of Stellenbosch is currently developing a low Earth orbit (LEO) microsatellite for communication and mapping purposes. Since this will be the first South-African-developed experimental satellite, the project will also be used to gain new technology for future aerospace and satellite applications. The authors discuss the power system requirements and propose solutions for the power system design on board the satellite. They discusss the simulation and analysis of the power system requirements of the orbiting satellite. Power electronic converters to be used will include maximum power point tracking, battery regulation, bus regulation, and distributed power conversion. The specification and designs of key components, i.e., the solar panels, battery, and regulators, are evaluated against the system requirements during a typical flight path. These simulations include all the different modes of operation of the power system in an orbit cycle.


People living with mental illness die on average 20 years earlier than the general population. For every one person who die from suicide, 10 to die prematurely due to chronic physical health conditions. The majority of these deaths are avoidable. However, due to a number of reasons, including lack of screening, diagnostic overshadowing, limited access, stigma and discrimination the life expectancy gap has actually increased over the last three decades. In response to this crisis, Australia, the UK and New Zealand have each instituted national initiatives entitled Equally Well. The Equally Well initiatives are designed to close the life expectancy gap, and work towards equal access, quality care, and parity of esteem for people living with mental illness. Integrating care across service providers (public health, non-government, private providers, and advocacy bodies), service types (promotion, prevention, acute care, chronic care), professions (GPs, psychologists, social workers etc) and district boundaries is a complex a challenging task. While each country has adopted a collective impact approach,1 the way this approach has been operationalised varies considerably by country. This presentation compares and contrasts the way the collective impact approach was implemented in the UK New Zealand and Australia. It will highlight areas of success, and also discuss aspects of the programs that have proven challenging. The presentation will also overview the governance models, social media strategies2 and collaboration mechanisms used, with particular attention to co-design and effective engagement with consumers and carers. Finally, it will examine the role and importance of creating and curating enabling resources such as tool-kits, literature reviews, clinical guidelines and consumer, and carer fact sheets to support collaboration and integration. 1.

The network brings convenience to the students, it also brings a lot of trouble. The research showed that most students' network life is reasonable, and found their different purposes for internet. But there is still a small part of the students were unable to take charge of their status over the Internet, They addicted to the game and neglect their studies, which bring about an extremely serious physical and psychological effects.


in a recent editorial in the Science magazine (Science 324:1241, 2009) Sharon Long and Robert Alpern, who chaired a committee of U.S. undergraduate and medical school faculty, comment on a report by this committee on Scientific Foundations for Future Physicians released by the Association of American Medical Colleges (AAMC) and the Howard Hughes Medical Institute. They state that "the new report emphasizes that physicians must have a firm grounding in the biomedical sciences and understand their relation to the physical sciences and mathematics. For physicians to be prepared for inquisitive, critical thinking and lifelong learning, they should also be able to incorporate the methods of science into their practice, including sceptical and critical analysis." The committee has to be congratulated for its careful and inspiring work which will have no doubt major impact. The full report which can be downloaded from www.aamc.org/scientificfoundations defines as one of the competencies that students by the completion of medical school should to be able to "apply knowledge of molecular, biochemical, cellular, and systems-level mechanisms that maintain homeostasis, and of the dysregulation of these mechanisms, to the prevention, diagnosis, and management of disease. I think this is exactly what modern physiology education should achieve! In my view, this vision clearly underpins the indispensable role for Physiology in Medical education. As you may know, FEPS has also started efforts on analysing the role of Physiology in teaching in European Medical schools. By reviewing Physiology teaching at European universities, ongoing organisation of teaching symposia at the annual FEPS-supported meetings and the installation of a FEPS Task Force on Physiology Teaching (chaired by Prof. Luc Snoeckx) we aim to form a network of European teachers. The task force assists FEPS in defining focuses of Physiological teaching which should help to provide a useful platform for those who need to (re-) establish Physiology, e.g. in the revisions of teaching enforced by the Bologna process. The definition of modern principles and contents of teaching Physiology is clearly a bottom up process which requires broad discussion and we invite all of you to contribute. At the end a FEPS paper will hopefully support physiologists at the European medical schools to emphasize the important impact of Physiology whenever it comes to revisions of medical teaching.

For clear sky conditions the flux estimate is determined with a parameterisation of the atmospheric transmittance as a function of the concentration of atmospheric constituents. For overcast sky a simple physical model of the radiation transfer in the cloud‐atmosphere‐surface system is employed, for which the satellite signal supplies the essential input information. The product has been validated with in situ data from six European ground measurement stations. The resulting statistics show a standard deviation of the difference between instantaneous satellite estimates and ground measurements in the order of 40 W m−2 for clear sky data and 110 W m−2 for cloudy sky data. For the complete sample including all data points the standard deviation amounts to 85 W m−2. The bias between the satellite product and the ground data is small with absolute values of less than 10 W m−2. Copyright © 2008 Royal Meteorological Society


The insulin tolerance test was performed in 10 patients before and after treatment of thyrotoxicosis. Plasma cortisol was measured in response to the insulin-induced hypoglycemia. As a group, no definite abnormality of pituitary-adrenal function was found, but some individual cases demonstrated impaired cortisol responses, suggesting that in severe stress steroid therapy may be necessary in certain hyperthyroid patients. Although fasting blood sugar levels were significantly elevated prior to treatment, following the onset of euthyroidism there was no alteration in the insulin sensitivity, which was normal.


Under a global environment characterized by open and complex information networks, academic library resource sharing practitioners should observe the information services market beyond their "library-oriented" settings and rethink the development directions of their services. To investigate this issue, this paper presents an analysis of the development trajectory and characteristics of DXY, a Chinese information service enterprise. This study also discusses the development of academic library resource sharing service from three dimensions: namely, service targets, service contents, and service roles. Findings show that the academic library resource sharing practitioners should break through the traditional cognitive frameworks of "academic users on campus" and "document providers," and furthermore, consider upgrading services to assume a comprehensive role as information sharer, information connector, and platform operator simultaneously. This change will enable the move toward a knowledge service orientation.


With excellent angular resolution, good energy resolution and broad energy band, the Chandra ACIS is the best instrument for studying the X-ray halos around some galactic X-ray point sources caused by the dust scattering of X-rays in the interstellar medium. However, the direct images of bright sources obtained with ACIS usually suffer from severe pile-up. Making use of the fact that an isotropic image could be reconstructed from its projection into any direction, we can reconstruct the images of the X-ray halos from the data obtained with the HETGS and/or in CC mode. These data have no or less serious pile-up and enable us to take full advantage of the excellent angular resolution of Chandra. With the reconstructed high resolution images, we can probe the X-ray halos as close as 1$''$ to their associated point sources. Applying this method to Cygnus X-1 observed with Chandra HETGS in CC mode, we derived an energy dependent radial halo flux distribution and concluded that, in a circular region (2$'$ in radius) centered at the point source: (1) relative to the total intensity, the fractional halo intensity (FHI) is about 15% at $\sim$1 keV and drops to about 5% at $\sim$6 keV; (2) about 50% of the halo photons are within the region of a radius less than 40$''$; and (3) the spectrum of the point source is slightly distorted by the halo contamination.


A set of partial differential equations of the Navier-Stokes type is derived for external rarefied gas flows at all Knudsen numbers. Only the expressions of the stress tensor and heat flux vector are different from the customary Navier-Stokes relations and Fourier law. The new expressions are calculated from an approximate distribution function constructed through analysis of the BGK model of the Boltzmann equation so that it retains the qualitative property of the collision term and reproduces accurately the two extreme continuum and free-molecule regimes. Explicit forms of the stress tensor and heat flux components are given for low-speed two-dimensional flows. Solutions for vanishing Mach number and compressibility effects are then discussed. For a nearly isothermal cylinder, the present formulation leads to only one governing equation of the Navier-Stokes type for all flow regimes.


. The lateral ordering of thechain segments during the period 178 to 680 ps of the simulation time was found to obey the Avramiequation with an Avrami index of 1 .44.


The NASA Glenn Research Center and Lockheed Martin Corporation tested an aircraft model in two wind tunnels to compare low-speed (subsonic) flow characteristics. Objectives of the test were to determine and document the similarities and uniqueness of the tunnels and to validate that Glenn's 10- by 10-Foot Supersonic Wind Tunnel (10x10 SWT) is a viable low-speed test facility. Results from two of Glenn's wind tunnels compare very favorably and show that the 10x10 SWT is a viable low-speed wind tunnel. The Subsonic Comparison Test was a joint effort by NASA and Lockheed Martin using the Lockheed Martin's Joint Strike Fighter Concept Demonstration Aircraft model. Although Glenn's 10310 and 836 SWT's have many similarities, they also have unique characteristics. Therefore, test data were collected for multiple model configurations at various vertical locations in the test section, starting at the test section centerline and extending into the ceiling and floor boundary layers.


Inspired by the success of the Students @ Work project [1] run at Hamburg University, Curtin University (Perth, Western Australia) has recently concluded the running of a pilot course in Second Life with their Information Systems Project (ISP) students. The need for a change was evident as student motivation and engagement in the Final Year ISP course was strikingly low. Left with such a tall order for improvement, the ISP teaching staff looked to find suitable options for change. Staff combined new and interesting tools in an effort to boost and maintain student interest, specifically the Second Life virtual environment and a screen capturing technique known as Machinima.


The excess production capacity of China is a problem of continuous concern of top decision-makers as well as a research topic engaging researchers in recen years. How to push forward the industrial structural adjustment to tackle the problem is getting increasingly impending with the slowdown of the economic growth in China. In the present paper, three methods are suggested for dealing with the problem:1.carrying out special monitoring over those industries in which the problem may develop easily;2.formulating plans in advance for tackling the prospective risks of the problem;3.working out a set of an integrated developing strategy for the real economy through research.


It has been an open question as to whether the Modular Structural Operational Semantics framework can express the dynamic semantics of call/cc. This paper shows that it can, and furthermore, demonstrates that it can express the more general delimited control operators control and shift.


A number of large rock avalanches from the northern slope of the 1435 m high mountain of Vora in Breim, inner Nordfjord have been mapped. The avalanche tongues dam the 4 km long Sandalsvatnet, they cover an area of 3 km 2 and the volume exceeds 100 million m3. Age estimates have been obtained by radiocarbon datings of rock dust layers in a bog and the Schmidt-hammer method. Altogether 11 large rock avalanches have occurred throughout the Holocene, of which six lobes can be recognized morphologically. Five silt laminae in a 5.5 m deep bog basin distally to the avalanche lobes are interpreted as primary sediments from dust clouds generated by rock avalanches. In addition three silt beds are interpreted as glaciolacustrine sediments related to temporary damming caused by landsliding. Average avalanche frequency during the Holocene was c. 1 per 1000 yr and during the period 7100—3600 BP it was c. 1 per 700 yr. After 3600 BP no rock avalanches have been recognized.


Aging impairs mesenteric lymph flow, which is crucial for fluid and macromolecule homeostasis, fat absorption, and immunity. Differences in contractile behavior of aged isolated mesenteric lymphatic vessels (MLV) and those observed in situ suggest an important regulatory involvement of some cellular elements in the immediate surrounding environment of aged MLV. We used whole mount immunohistochemistry and vital staining to identify and characterize mast cells (MCs) surrounding MLV in adult and aged Fischer‐344 rats. Additionally, we investigated the aging‐associated differences in MCs activation in the mesenteric bed in control and treated conditions. We used mesenteric tissue segments for acute treatments with 48/80, and biological activators, and used Ruthenium Red staining to identify activated MCs. Degree of activation was assessed by the image analysis of activated cells in control and treated conditions. We found a greater degree of pre‐activation of MCs in control conditions in aged rats compared to adult animals. Such pre‐activated status of aged MCs reflects lesser ability of aged MCs and adjacent MLV to adequately react to acute stimulation in elderly. These findings serve as first step in investigations of the aging‐associated mechanisms that potentially link MCs function, inflammation, and functional contractile disturbances in aged MLV.

In the article, the concept Ivanushka-durachok is considered as a national precedent name. The national-cultural significance of the concept is proved based on the opinion of predecessors. The deformations of the axiological paradigm of young Russian speakers are exemplified by this concept, modifications in its existence are fixed overtime. It is argued that the change in the semantics of the concept Ivanushka-durachok is explained by the development of the linguistic consciousness of native speakers over the past 40 years. In the course of the research, the psycholinguistic methods and the methods of corpus linguistics were used. The dynamics of the evaluative value of the precedent concept Ivanushka-durachok is indicated. It is concluded that the axiological and semantic potential of the concept Ivanushka-durachok and its name has been deformed. Its assessment vector in the linguistic consciousness of the student changed from positive to slightly negative. It was found that most of the preschoolers and some schoolchildren do not know the hero at all, do not have any associations with him, poorly represent his character traits, do not remember the fairy tales in which the character participates, do not reproduce the plot collisions associated with the hero, do not have a complete (and some even partial) understanding of the actions and characteristics of the hero and his antipodes, his environment. This is evidenced by the results of an associative experiment, according to which the hero is still recognizable as a fairy tale and folklore character inscribed in the schoolchild's world picture. However, he is not attributed as invincible, disinterested, kind, trusting in the will of God, savvy, fearless, generous, highly moral. The hero is perceived primarily as intellectually limited, unkempt and unengaging. According to schoolchildren, the character is not suitable for personal friendship. The author considers the simplification and transformation of Ivanushka-durachok's assessment to be a mutation of the cultural code. The change of axiological emphasis exemplified by Ivanushka-durachok is assessed as a diffusion of national-cultural idiosyncrasy, its unjustified debasement. The results of the analysis can help to correct the work with fairy-tale and folklore texts in kindergartens and elementary schools, be used in the teaching methods of literary reading.


A tilt mechanism (10) for a chair comprises a base (11), a back bracket (12) configured to support a chair back (4) and a coupling arrangement (16, 25) configured to couple the back bracket (12) to the base (11). The coupling arrangement comprises a guide track (25) and a guide member (16). One of the guide track (25) and the guide member (16) is provided on a portion of the back bracket (12) extending from a back attaching portion (23) to a pivot coupling portion (24) at which the back bracket (12) may be articulated to a chair seat (3). The other one of the guide track (25) and the guide member (16) is provided on the base (11). When the coupling arrangement (16, 25) couples the back bracket (12) to the base (11), pivoting the back bracket (12) about the pivot coupling portion (24) causes the guide member (16) and the guide track (25) to be displaced relative to each other, effecting a displacement of the pivot coupling portion (24) relative to the base (11).


Abstract Integrative taxonomic study of three species of the genus Tylostega revealed that the genetic distances of the COI gene among the tested species was relatively large (3.27–7.60%). The Automatic Barcode Gap Discovery (ABGD) system performed better than the Barcode Index Number (BIN) in discriminating closely related species. This work provides a molecular baseline for future integrative taxonomic study of Crambidae.


This chapter presents an overview of cell entry by nidoviruses, and focuses on the functioning of the coronavirus fusion protein, in particular, on its proteolytic cleavage activation and on its conformation rearrangements in the process of membrane fusion. The actual fusion reaction is primed by interaction with the target cell where any of a number of triggers-receptor binding, proteolytic cleavage, or acidic pH-can spark off a cascade of conformational changes by which the metastable trimer eventually ends up in a trimer-of-hairpins conformation that is characterized by two main features: a six-helix bundle structure formed by the antiparallel association of the HR1 and HR2 domains, and the juxtaposed fusion peptides and transmembrane domains anchored together in the fused lipid bilayer. With regard to the intermediate conformational states, experimental support has only been obtained for the occurrence of a prehairpin intermediate in which the fusion peptides, originally hidden away in the native trimeric structure, have become exposed, pointing away from the viral membrane and into the target membrane. The authors describe how coronavirus membrane fusion fits in this picture by discussing the triggers, the key structural elements in the spike protein, its conformational states, and the actual fusion process. Membrane fusion is currently viewed as a process with defined events: merging first of the apposing leaflets (lipid stalk formation or hemifusion) and then of the distal leaflets (fusion pore formation), followed by fusion pore enlargement.


This study aimed to identify and implement educational strategies through the use of Information and Communication Technologies in order for students of distance learning (who belong to the academic degrees of Natural Sciences and Environmental Education at the University of Cordoba) to develop comprehensive competences. We used the action research method divided in two cycles, with the participation of three teachers and 242 students. The data analysis of the first cycle established three analysis categories and designed four intervention strategies based on the scientific knowledge and the academic experience of the teachers. The results of the second cycle showed an improvement of the academic performance of the students in a comprehensive way.


We can conclude that the Hungarian Penal Code does not include statutory regulations fore the consent of the aggrieved person. To be able to adopt this instrument The judicial practice made this legal institution applicable by developing its conditions and background. Given that the consent of the aggrieved person restricts the scope of criminal liability I do consider that this institution is agrees with the requirements of the sate constitution. I would also like to point out that several authors 1 ) are on the opinion that the consent of the injured person should be regularized with a statutory rule to ensure the requirements of legal certainty. However, the new Penal Code, that is currently in the phase of public harmonization, does not include it, either.

Typically, strong earthquakes do not occur over the entire territory of the seismically active region. Recognition of areas where they may occur is a critical step in seismic hazard assessment studies. For half a century, the Earthquake-Prone Areas (EPA) approach, developed by the famous Soviet academicians I.M. Gelfand and V.I. Keilis-Borok, was used to recognize areas prone to strong earthquakes. For the modern development of ideas that form the basis of the EPA method, new mathematical methods of pattern recognition are proposed. They were developed by the authors to overcome the difficulties that arise today when using the EPA approach in its classic version. So, firstly, a scheme for the recognition of high seismicity disjunctive nodes and the vicinities of axis intersections of the morphostructural lineaments was created with only one high seismicity learning class. Secondly, the system-analytical method FCAZ (Formalized Clustering and Zoning) has been developed. It uses the epicenters of fairly weak earthquakes as recognition objects. This makes it possible to develop the recognition result of areas prone to strong earthquakes after the appearance of epicenters of new weak earthquakes and, thereby, to repeatedly correct the results over time. It is shown that the creation of the FCAZ method for the first time made it possible to consider the classical problem of earthquake-prone areas recognition from the point of view of advanced systems analysis. The new mathematical recognition methods proposed in the article have made it possible to successfully identify earthquake-prone areas on the continents of North and South America, Eurasia, and in the subduction zones of the Pacific Rim.
