The purpose of this study was to examine the effects of using mobile technology to improve navigation skills in three students with intellectual disability (ID) in a postsecondary education program. Navigation skills included using an augmented reality iPhone app to make correct "waypoint" decisions when traveling by foot on a university campus to target destinations. The results indicate that all students improved their navigation skills. Findings are discussed in the context of teaching the use of mobile technology to improve wayfinding skills in students with ID.


Chirped echoes from staircases at the temple of Kukulkan at Chichen Itza have stimulated much interest since first reported at scientific meetings by the author in 1998. Among them are Declercq et al (J. Acoust. Soc. Am. 116, (6) 2004). They correctly observed that the echo depends strongly on the "type" of incident sound, but offered no explanation. Those authors overlooked an earlier explanation given at the First Pan‐American/Iberian Meeting on Acoustics at Cancun, Mexico (Lubman, J. Acoust. Soc. Am. 112, (5) (2002). It included a mathematical model of the chirped echo effect and a full simulation of the chirped echo, including auralization. This model explicitly shows echo dependence on the time‐frequency structure of the impinging sound. With it, ethnomusicologists and others can conveniently simulate the staircase echo for any recorded sound stimulus, including handclaps, voices, and ethnic sound instruments. The clap‐echo system is modeled as a time‐invariant linear system. The echo time series is ...


The authors investigate the influence of inter-bit four-wave mixing on optical time division multiplexed transmission. The effect is caused by pulse broadening due to fibre dispersion and four-wave mixing between overlapped pulses. The authors also confirm this effect experimentally and show that there is an optimum pulsewidth to reduce both four-wave mixing and self-phase-modulation effects.


Critical thinking skills are essential skills of the 21st century which are very important for students to master. Unfortunately, some research results show students' low critical thinking skills. One important component that supports the teaching of critical thinking for students is learning tools. The results of the preliminary study show the lack of learning tools that are oriented towards students' scientific activities so that it is suspected to be the cause of students' low critical thinking skills. This study aims to evaluate the validity of inquiry-based biology learning tools that can explicitly be used to teach critical thinking skills. This research is descriptive-evaluative research because it only evaluates the results of expert judgment on the validity of the developed learning tools. Two validators with professor qualifications were involved in this study to evaluate the validity of the product using the validation sheet instrument. The results showed that the learning tools developed in the form of lesson plans, learning materials, student worksheets, and critical thinking ability tests were generally stated to be valid (score = 3.65) and reliable (score = 0.93) used to teach students' critical thinking skills in system teaching materials Respiratory. Further research related to the practicality test and the effectiveness of the resulting device needs to be carried out in further research

Radioactive source liability insurance refers to the form of insurance in which the insurer shall be liable for compensation according to law when the insured uses radioactive sources to cause radiation damage or environmental pollution to a third party and is claimed for compensation. This paper deeply investigates the practical experience of various countries in the field of radioactive source liability insurance; this type of insurance has a lot of mature application experience in Europe & US, the two major nuclear damage compensation convention systems have not yet stipulated the liability insurance of radioactive sources, European countries have a strong awareness of applying for radioactive source liability insurance. Then it makes a detailed analysis of the current laws and regulations in the field of nuclear technology utilization and the current situation of liability insurance in the field of radioactive sources in China. At present, there is no special law on liability insurance in the field of radioactive sources, there are still several problems, including the weak awareness of risk prevention of enterprises using nuclear technology, the lack of social responsibility of some enterprises and their unwillingness to buy insurance.
 In order to solve the above problems, the following four recommendations are made. First, improve the legal and policy system of radioactive source liability insurance in China. Second, pilot the implementation of radioactive source compulsory liability insurance in high-risk industries or enterprises. Third, promote personalized insurance rates and insurance limits. Fourth, carry out health damage insurance for employees in the field of radioactive sources at an appropriate time. Finally, it provides a strong and valuable reference for the future radioactive source liability insurance in China.

Purpose This study aims to determine the seroprevalence of coronavirus disease (COVID-19) among health care workers and describe the associated sociodemographic and labor features. Patients and Methods An observational study with an analytical component was conducted at a clinic in Cali, Colombia. The sample size was 708 health workers and they were selected by stratified random sampling. A Bayesian analysis was developed to determine the raw and adjusted prevalence. A Poisson regression model was used to estimate the prevalence ratios. Results Overall seroprevalence of COVID-19 among healthcare workers was 29%. Miscellaneous services workers, healthcare, and administrative workers, was 38%, 33%, and 32%, respectively. Factors related to seropositivity were having a contact with a COVID-19 patient for >120 minutes and being diagnosed with COVID-19 by laboratory tests. Conclusion The present study shows a adjusted seroprevalence of 29% in health workers, indicating a high level of disease transmission and an increased risk of infection in this population group.


The representational surface has become an effective means for expressing the anisotropy in piezoelectric single crystals and textured polycrystalline materials. Although the mathematics involved with such a representation can be taught at the graduate level, the knowledge and familiarity necessary to represent these surfaces graphically makes such representations inaccessible to some undergraduate and graduate students. This paper presents a simple, user-friendly tool for generating such representations for 3rd-rank tensors and demonstrates their application to a specific piezoelectric composition. The tool is accessed as a graphical user interface within a commercial mathematical software package.


Abstract : As part of a national study analyzing the relation between hydric soils and wetland vegetation, the vegetation associated with a series of known soils was sampled along the Connecticut River floodplain in Massachusetts. Weighted average and index average (presence/absence) values were calculated for vegetation using wetland ecological index values from the National List of Plant Species that Occur, in Wetlands developed by the U.S. Fish and Wildlife Service and procedures developed by T. R. Wentworth and G. P. Johnson at North Carolina State University. Good correspondence between soils and vegetation was recorded with two exceptions. Two typically nonhydric soils were determined to be hydric based on vegetation analyses. Examination of the groundwater hydrology of these two soils confirmed their hydric nature. The authors suggested that one of these soils may need to be redefined and they also suggested that the assigned index values for a few species of vegetation should be reexamined. However, in general the index average values of vegetation based on published wetland index values corresponded with the hydric and nonhydric nature of soils.


Mosquito has comprehensive and sensitive olfactory neuro-sensory located at antenna utilized for detecting airborne organic compounds in search of blood host. Mosquito is also known to have similar neurotransmitters function with human at neural synapses e.g. acetylcholinesterase, esterases and oxidases enzymes. Thus, there is potential use mosquito in predicting neurotoxicity of exogenic volatile organic compounds (VOC) e.g. manufactured acetone. Hence, the study evaluates the suitability to conduct bioassay of VOC neurotoxicity against mosquito in Peet Grady chamber that is commonly used for insecticidal bioassay. Acetone as the representative of VOC is easily evaporized at laboratory temperature of 26 to 29 °C without heating. The acetone evaporation profile on liquid surface and porous solid surface under the Peet Grady chamber is studied to ascertain the consistency of vaporization rate with homogenized distribution. The study showed the acetone has shown consistent vaporization rate of 23 mg/min from liquid surface and 116.3 mg/min from porous surface (filter paper) without heating, in a linear regression of very high positive correlation (r = 1.000) between time and mass of acetone vaporized. However, the non-homogenized distribution of acetone vapours in the Peet Grady chamber directly affected the accuracy to elucidate the neurotoxicity bioassay against mosquito in term of mosquito knockdown. The study suggests the positioning of mosquitoes in the Peet Grady chamber should be lower than the point of acetone vaporization, whereby the mosquitoes are knockdown by acetone vapours within the 20th minute upon reaching concentration of 170.3 to 196.1 ppm.


As a part of our ongoing studies in developing new derivatives as dual antibacterial/antifungal agents, we describe the synthesis of novel amino substituted benzofuroxan derivatives. These compounds were tested for their antifungal activity against various strains. It is shown that their antimicrobial and antifungal activities depend on the structure of the amino moiety, on the position and on the nature of the substituents of the benzofuroxan ring. They displayed good bacteriostatic and fungistatic activities comparable to those of reference drugs. The more active benzofuroxan derivatives have been studied intraperitoneally in mice to get a first estimation of their toxicity. Preliminary results have also shown that some derivatives are able to inhibit enzymes such as GDH (glucose dehydrogenase).


To the Editor, Isolated tricuspid valve endocarditis (TVE) is a rare disease and clinical data associated with surgical treatments remain uncertain. Voss et al. observed using their single‐institute data that mortality in patients with isolated TVE receiving cardiac surgery was high. In half of the cases, tricuspid valve repair was achieved but was less likely performed in patients with affected subvalvular apparatus. Several concerns have been raised. More detailed baseline characteristics data would be useful to better understand the risk factors of isolated TVE. For example, the existence of cardiac devices was one of the major etiology of TVE. Which devices did patients with TVE have dominantly? Also, the existence of right heart failure was one of the major indications of cardiac intervention for TVE. Detailed data regarding echocardiographic right heart function including tricuspid annular plane systolic excursion and medication data including the dose of diuretics would be helpful to understand the severity of right heart failure. One of the major complications of TVE would be pulmonary embolism, which is not stated in their manuscript. Did the authors assess the existence of pulmonary embolism or were there patients with severe hypoxia before the cardiac surgery? One of the major concerns for many readers would be preoperative risk stratification. For example, Four out of nine patients with right heart failure at baseline died following cardiac surgery in their study. Such patient eventually died due to persistent heart failure despite cardiac surgery? Did they receive appropriate guideline‐directed medical therapy following the surgery?


This research investigated the effect of co-curricular activities on academic achievements of special educations students with learning disabilities in SMK Permata Jaya, Rengit, Batu Pahat, Johor, Malaysia. 20 students from special educations class session 2015 were selected for moderate level syllabus and another 20 students were using high level syllabus constituted a study sample. Each level of students taught by the same teacher was divided into experimental and control groups. The experimental groups were involved in co-curricular activities and the control groups did not participate in any co-curricular activity. They were two types of co-curricular activities which are physical activities and the other was like debates, speeches and drama. Raw scores of the students from the subject of Science test made up data for the study. Data analysis involved the use of mean scores and t-test of significant difference between two independent group means scores, supported by F-test of homogeneity of two independent group variances It was found that co-curricular activities had significant effect on academic achievements of the experimental groups.

1 −→ K(R) −→ SLn(R) mod mR −→ SLn(Z) −→ 1, for R = Z[t],Z[t, t−1], mR = (t), (t − 1), respectively. The group K(R) consists of matrices congruent to the identity modulo mR; it has a filtration K•(R) defined by K(R) = {X ∈ K(R) : X ≡ I mod mR}. The graded quotients all satisfy K(R)/K(R) ∼= sln(Z). Consider the extension 1 −→ U −→ SLn(Q[[T ]]) T=0 −→ SLn(Q) −→ 1. The group U has a filtration U• by powers of T and we have injections SLn(R)→ SLn(Q[[T ]]) given by sending t 7→ T and t 7→ 1 + T , respectively. Theorem 3.6 asserts that the map K(R)→ U is the Malcev completion. The proof given in the paper is incorrect.


Modern road vehicles are employing features of driver assistance systems (DAS) to improve drivability performance, comfort, and safety. In the future perspective, the advances in this field will lead these systems to the level of autonomous and cooperative driving, based on sensors networks and sensor fusion. This paper aims to present the readers a novel strategy for lane detection and tracking, which fits as a functional requirement to deploy DAS features like Lane Departure Warning and Lane Keeping Assist. To achieve the presented results, the digital image processing was divided into three levels. At the low-level, the input image dimensionality is reduced from three to one layer, the sharpness is improved, and region of interest is defined based on the minimum safe distance from the vehicle ahead. The feature extractor for lane edges detection design is part of the mid-level processing. The lane tracking strategy development is discussed in the high-level stage; Hough Transform and a shape-preserving spline interpolation are used to achieve a smooth lane fitting. The experimental outcomes were qualitatively and quantitatively evaluated using a ground truth comparison. The strategy shows good accuracy levels, including scenarios with shadows, curves, and road slope.

In exposed hearts of anesthetized dogs with total A-V block, a sudden increase or decrease in heart rate changes the duration of refractoriness immediately. A steady state is established only after a few hundred beats. The time course of shortening of the refractory period caused by an increase in driving rate ("on" effect) has the following characteristics. The first beat shortens the refractory period, as determined from strength-interval curves, about 30% of the total shortening; the second beat shortens it 10% more. After the second beat, the rate of change in the duration of the refractory period suddenly becomes slower. Alternation of the refractory period begins with a slightly prolonged refractory period of the third beat and then diminishes rapidly in about the following 10 beats. These changes are in phase throughout the ventricular myocardium. Following sudden transition to a slower rhythm, the time course of lengthening of the refractory period ("off" effect) is opposite to the "on" effect: the alternation that occurs is less marked. Changes in the duration of the functional refractory period near the stimulus site are parallel to those in the threshold curves. These results demonstrate a long persistence of the effect on myocardial refractoriness of a previous cardiac frequency.

This paper is aimed to develop a new actuator used in assistive knee braces for helping elderly or disabled people to recover their mobility. In the design, magneto-rheological (MR) fluids are integrated into the actuator to provide controllable torque and improve the braking control performance. With MR fluids, the actuator possesses multiple functions as motor, clutch, and brake while meeting the requirement of normal walking as well. In this paper, design considerations including actuator configuration, magnetic circuit and influence of permanent magnet on MR fluids are discussed. Finite element model of the actuator is built and analyzed. Modeling of the actuator in different functions is presented. A prototype of the actuator is fabricated and tested. Braking torque control of the actuator is investigated. The results show that the developed multifunctional actuator is promising for assistive knee braces.


The existence of a wide range of actual or potential threats with effective impact on the business entities is a certainty, as well as their influence on the results of the entity (often negative). In this context, increasing economic performance and conducting effective activities are strictly related to implementing a system of internal control. With the possessed tools and techniques, internal control evaluates the activities accomplished by the entity and identifies the risks that it faces. Therefore, presenting a fair view of the entity requires the implementation and development of internal control processes.


We present a new data product, called Space-Weather MDI Active Region Patches (SMARPs), derived from maps of the solar surface magnetic field taken by the Michelson Doppler Imager on board the Solar and Heliospheric Observatory. Together with the Space-Weather HMI Active Region Patches (SHARPs), derived from similar maps taken by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory, these data provide a continuous and seamless set of maps and keywords that describe every active region observed over the last two solar cycles, from 1996 to the present day. In this paper, we describe the SMARP data and compare it to the SHARP data.

Methane and ethylene were plasma-polymerized onto polyethylene (PE) and polypropylene (PP) substrates. Several properties of the deposited films, such as deposition behavior, density, oxygen permeability, and adhesivity, were investigated. The deposition rate of ethylene was found to be about 4-5 times greater than that of methane. The density of plasma-polymerized ethylene was determined to be 1.00 g/cm3. Adhesivity of plasma-polymerized ethylene films on high-density PE (HDPE) and PP was high enough when O2 pretreatment was preceded. Without O2 pretreatment, the adhesivity on HDPE was slightly better than that on PP, and a higher adhesivity on HDPE was observed for the film plasma-polymerized at a higher plasma-energy density with low ethylene flow rate. Oxygen permeability of plasma-polymerized low-density PE (LDPE) film was reduced considerably by the deposition of ethylene-plasma-polymer films.


In an examination of the relationship between the black hole mass M BH and stellar velocity dispersion σ * in radio-loud active galactic nuclei (AGNs), we studied two effects which may cause uncertainties in the black hole mass estimates of radio-loud AGNs: the relativistic beaming effect on the observed optical continuum radiation and the orientation effect on the broad emission line width. After correcting these two effects, we re-examined the M BH – σ [OIII] relation for a sample of radio-loud and radio-quiet AGNs, and found the relation for radio-loud AGNs still deviated from that for nearby normal galaxies and radio-quiet AGNs. We also found there is no significant correlation between radio jet power and narrow [OIII] line width, indicating absence of strong interaction between radio jet and narrow line region. It may be that the deviation of the M BH – σ * relation of radio-loud AGNs is intrinsic, or that the [OIII] line width is not a good indicator of σ * for radio-loud AGNs.


The internal rotation of hydrogen peroxide molecule is treated on the assumption that the hindering potential is approximately expressed by the two‐term Fourier expansion: V=(V1/2)(1+cosχ)+(V2/2)(1+cos2χ). The doublet structure of the infrared absorption spectrum is considered to be caused by the existence of a double minimum in the hindering potential. The available experimental data on the microwave spectra and on the infrared combination bands yield the result of V1=244 cm—1 (700 cal/mole) and V2=319 cm—1 (910 cal/mole). Thus it is concluded that the cis barrier (452 cm—1 or 1290 cal/mole) is definitely higher than the trans one (208 cm—1 or 590 cal/mole).


The linearized point-kinematic fixture model only includes thefirst orderpropertyof the contactsurface, and onlytakes into account of the locator error along the surface normal. Thus the fixture inaccuracy resulting from the surface geometric properties is ignored. In view of this and the difficulty to construct a more sophisticated locating error evaluating schemefromthe exactsurface geometryequation,this paper presents a method to analyze the workpiece locating error resulted from the locators' error along the contact surface. The method is originated from the understanding that the locater error along the contact surface changes not the input of the model, but the structure of it. A further theoretical explanation on how the curvature and other higher order properties affect the workpiece locating error is also presented. The numerical example shows that the error estimated with this method approximates the exact error well.

For a family of length-4N orthonormal scalar wavelet filters that has been shown to be closely related to symmetric/antisymmetric orthonormal multifilters (SAOMFs), a sufficient and necessary condition is given for their construction. A near-linear criterion is then provided for constructing balanced multiwavelet filters related to these scalar filters. Numerical results are presented to demonstrate the potential usefulness of this criterion.


The normal accident prediction models can't predict the occurrence of major accidents very well, so the cusp catastrophe model of major accidents is set up on the base of ideas of black swan and catastrophe theory. In the model, the main factors of major accidents are regarded as the controls parameters and the functional status of the system as the state parameter. The model has filled up the blank field of studying emergency in the black area. It is well explained by the model that the project state depends on the interaction between human factors and material factors. In the further step, the mechanism of major accidents can be generalized. The model is applied in the case of port engineering. To avoid major accidents, the corresponding measures would be taken according to different states of the port engineering. Through the application, the model is proved to be useful in the engineering practice.

Adverse events such as disasters are interpreted through a system of meaning provided by culture. Historically, research into society's response to disasters provides numerous examples of community resilience in face of adversity. However, since the 1980s, numerous researchers have challenged the previous optimistic accounts and argue that such incidents result in long-term damage to the community. It is claimed that community response to a disaster episode is far more likely to be defined by its vulnerability than its resilience. This new vulnerability paradigm of disaster response is underpinned by the belief that contemporary technologically driven disasters have a peculiarly destructive outcome. This paper explores the changing conceptualisation of adversity. It suggests that the shift from the expectation of resilience to that of vulnerability is best understood as an outcome of a changing cultural conceptualisation of adversity.

According to the National Health Surveillance Agency (ANVISA), 30 thousand tons of medicines are wasted by consumers in the country per year. The chemical substances it contains in medicines, most of the time, when disposed of incorrectly, can be toxic and contaminate rivers, soils, oceans and groundwater. The objective of the study is to assess the level of knowledge of undergraduate pharmacy students at a Private University in Fortaleza / CE, on the proper disposal of medicines. The study is descriptive, quantitative, carried out through the application of a questionnaire with a sample of 100 students. Of the interviewees, 65% (N = 65) were between 18 and 23 years old, the most prevalent age group 37% (N = 37) of the interviewees said that group B is the correct one for disposing of medicines. Regarding the disposal site, 41% (N = 41) affirm that the best known location was pharmacies and 98% (N = 98) agreed that incorrect disposal can harm the environment and 2% (N = 2) said that disposal does not harm the environment 56% (N = 56) of students reported knowing some type of legislation on the disposal of medicines and 44% (N = 44) are unaware of any information on legislation. The pharmaceutical professional is one of those responsible for educating patients and the general population regarding the correct disposal of expired or disused drugs. It is concluded that academics have disabilities when it comes to the correct disposal of medicines and the legislation, and it is important to take a more active action to raise awareness of the importance of the correct and safe disposal of medicine residues.


On April 6, 1939, FBI agents shot and killed America's "Public Enemy Number One" as he exited a St. Louis hamburger shop. Agents on the scene claimed the man, Ben Dickson, refused to surrender and threatened agents with two guns he carried. FBI documents and witness accounts, however, show that Dickson was shot in the back as he tried to run away from agents. Confronted by critics in the news media who questioned the legitimacy of the shooting, FBI officials in Washington worked with agents on the scene to concoct a version of events more amenable to the heroic media portrayals they preferred. Using FBI files released under the Freedom of Information Act and media accounts, this study explores the bureau's behind-the-scenes work to legitimize the shooting and its use of the revised version of events as a public relations device demonstrating the bureau's responsibility and utility.


Partially cyclized polyamide acid(PAA) solution was electrospun into nanofibers.The rheological properties of different PAA solutions and the mechanical properties of the resulting nanofibers were discussed.IR spectrum and SEM were used to characterize the imidized extent and surface morphology of nanofibers.The results showed that increasing the amount of cyclizing agent increased the imidized extent of PAA,the viscosity decreased when the shear rate increased,and more rigid the molecular chains,more obvious the decreasing of viscosity.Increasing the viscosity of the solution,the nanofibers became straight and the fiber diameter increased.The PAA nanofiber sheet′s maximum tensile strength and elastic modulus were about 16.87、(254.77 MPa),respectively.

The swing arm profilometer realizes the measurement of the different surface shape by adjusting the axis of the arm bearing and the axis of the workpiece bearing for different spatial positional relationships,so the high precision positional relationship between the axis of the arm bearing and the axis of the workpiece bearing is the premise to obtain accurate result. This paper presents a way using four-based laser trackers to calibrate the axes of the swing arm profilometer,that satisfies the requirement of the high precision and the dynamic calibration. The four-based laser trackers system only uses the precise distances to obtain the coordinates of points. The coordinates of points in the rotate arc of the axes can fit the axes,and the relationship between the axes can be know. The study of the self-calibration of the four-based laser trackers, the arrangement of four-based laser trackers, the design of the calibration method and the processing of measurement data are included in this paper. Finally, the study is validated by the preliminary experiment.


In Electro-Optical tracking systems, compound control is used to keep high-precision tracking of fast targets by predicting the trajectory of the target. Traditional ground based Electro-Optical tracking system uses encoder data and target missing quantity read from image sensors to achieve the target trajectory by using prediction filtering techniques. Compared with the traditional ground based systems, relative angle between the tracking system and the ground cannot be read directly from encoder data in an Electro -Optical tracking system based on moving platform. Thus the combination of inertial sensors' data and target missing quantity is required to composite the trajectory of targets. However, the output of the inertial sensors contains not only the information of the target's motion, but also the residual error of vibration suppression. The existence of vibration suppression residual error affects the trajectory prediction accuracy, thereby reducing compensation precision and the stability of the compound control system. Independent component analysis (ICA) method that can effectively separate the source signals from the measurement signals is introduced to target trajectory prediction field in this paper. An experimental system based on the method is built by settling a small dual-axis disturbance platform, which is taken as the stable platform, on a large dual-axis disturbance platform, which is used to simulate the motion of the moving platform. The result shows that the vibration residual is separated and subtracted from the combined motion data. The target motion is therefore obtained and the feasibility of the method is proved .

There has already been a significant spillover of the armed conflict in Colombia. The contraction of the Colombian government's authority has facilitated the spread of guerrilla, paramilitary, and drug trafficking activities to neighboring states. PANAMA With highly permeable land, sea, and air borders with Colombia, a well-developed financial and commercial infrastructure (including the Colón Free Zone, the second largest in the world), and negligible security forces, Panama has become a critical node in the Colombian narcotraffickers' and guerrillas' support structure. Drugs transit Panama from Colombia for transshipment to the United States and Europe, while arms and supplies move the other way. Outside of major towns, the Panamanian authorities have lost control of the southernmost province of Darién, bordering on Colombia, which has effectively become an extension of the Colombian northwestern theater of operations. According to Panamanian sources, two battalion-sized FARC fronts, the 57th and 58th, operate in Darién, and the FARC maintains a major logistics and support base in Panamanian territory near the Colombian border. The narcotraffickers and guerrillas have also developed a support infrastructure in small ports on the Atlantic coast of Panama that enables them to move drugs, arms, supplies, and personnel by sea. Panamanian security forces—a national police force that includes a specialized component with rudimentary light infantry training, and air and naval services—are no match for the heavily armed Colom


Abstract : This study reveals the social history of transmigration's effects on the chirstianization of pasaman. This chirstianization took place in 1953, for the existence of christians who have settled in about the 20th century. These christians came from java, and it's mainly in transmigration resettlement areas. In progress until the end of 1980, chirstian activity look dinamics, so that christian could engage in various activity of life. The study uses historical science research methods of heuristic, critisim, interpretation, and historiography. Studies have found that, the social movement of christian resulted from transmigration trough all walks of life in the pasaman. The christian movement in the pasaman included education, place of worship, youth and art, and socioeconomic society. A propesive action is that without resorting to anarchy in a persuasive or inviting approach. This effrot has brough various froms of infrastructure to all sector of life.Keywords : Impact, Transmigration,Christianization, Pasaman.


We propose a novel approach to relational clustering: Given a matrix of pairwise similarity values between objects our algorithm computes a partition of the objects such that similar objects belong to the same cluster and dissimilar objects belong to different clusters. The proposed approach is based on the assumption that the given similarities are products of cluster membership variables. It is based on eigen vector decomposition and minimizes the squared error between the similarities and the products of membership vectors in an efficient, non-iterative way with guaranteed global optimality. In experiments with real world data we show superior performance to conventional iterative clustering approaches.


In Chapter 12, we present the three primary hexachords used in the Renaissance, plus basic advice on how to apply them to the music. We also consider Martin Agricola's suggestion that the six different hexachord syllables had distinctive intrinsic qualities, which could open up new expressive possibilities for the more advanced musician approaching renaissance music.


Objective. To determine the prevalence of the Coqueluchoide Syndrome and Bordetella pertussis in the
pediatric population of the Zacatecas state, during the period January 2008 to February 2015. Materials and
methods. A descriptive, observational, not experimental, retrospective and cross-sectional study in pediatric
patients diagnosed with coqueluchoide syndrome positive in addition to patients with B. pertussis infection
attending in medical care units of health services in Zacatecas state. Results. B. pertussis remains a serious
health problem in the world and now confirmed in Zacatecas state. A small number of states have reports
that alarming increase in cases of infection caused by B. pertussis, although in some cases other numbers
have been in decline. The reason for variability of epidemiology of the decreased is still not yet well
established. Some factors such as demographic changes, lack of immunizations, and the evolution of the
bacteria may exacerbate this problem. Conclusions. This suggests that according to recent national articles of
B. pertussis Zacatecas state is only slightly below the national average, which is disturbing, with an equal
display conduct in children under one year. It's a need to consider the development of epidemiological
studies that help characterize the factors that represent a higher risk in pediatric patients.


The article argues for the audience studies, which draws on the analysis of artifactual, spatial, temporal, and sensorial aspects of media consumption and builds on, that is, the so-called medium theory and theory of practice in sociology. In the second part of the article, we interpret the results of a qualitative empirical study regarding the daily use of media technology among young people, aged between 19 and 29 years. The study finds that circumstances, under which digital media have colonized all spheres of public life and under which online social life has become completely naturalized, have led to constant online connectivity as well as highly fragmented and dispersed communication practices of users moving between different media. The analysis of media consumption diaries points to radical mediatization, which plays an important role in the changing generational structure of feeling.


 Road Recognition and Obstacle Detection • The extrinsic calibration is based on observing a planar checkerboard pattern. • On-road markers such as lane, speed bump, crosswalk, and stop line are detected in image using Hough transformation. • Curb is detected with laser sensor on the top of the vehicle using particle filter algorithm. • Both size and distance of obstacles on the road are simply detected by laser sensor at the front of the vehicle.  Rule-based Behavior Planning • ESTRO can select proper behaviors corresponding to road environment for driving safely and efficiently. • Five driving modes : normal road, crosswalk, speed bump, intersection, and obstacle avoidance driving mode.


Several isolates of Trichoderma koningii Oud. aggr., T. harzianum Rifai aggr., and T. hamatum (Bon) Bain. aggr., recovered from maize (Zea mays L.) plants or maize field soil, produced first-internode lesions in maize seedlings. Lesions were produced in 70–100% of seedlings grown in soil containing 104 or 105 propagules of T. koningii per gram and in 0–10% of seedlings in soil with 103 propagules. The following selective medium was developed for quantitative recovery of Trichoderma spp. from soil: peptone–dextrose agar, rose bengal (17 mg/liter), streptomycin sulfate (30 mg/liter), and formalin (200 ppm). Numbers of propagules of Trichoderma spp. per gram of field soil cropped with maize under zero tillage or conventional tillage, or with soybeans (Glycine max L.) ranged from 5,300 to 15,600, 350 to 1,650, and 20 to 180, respectively, during the growing season. Populations of Trichoderma spp. in soil of maize microplots in which maize tissues were incorporated were greater than in those without added maiz...


PLGA/bioactive glass composites were prepared as promising bone-repairing materials. The bioactive glass was fabricated by Sol-gel method. Surface Modification was done to improve the phase compatibility between polymer and the inorganic phase. PLGA/bioactive glass composites were successfully prepared via solution dispersion method. Composites films with different content of bioactive glass were obtained. The mechanical properties of composites were characterized by the three-point-bending test and composites films were investigated by in vitro bioactive test. These results indicate that the fractions of bioactive glass in composites produce no significant influence on mechanical properties. Compared to pure PLGA film the PLGA/bioactive glass composites demonstrate greater capability to induce the formation of apatite particles on the film surface.


The possible association between diabetes and cancer was first launched in 1932, when cancers in the intestine, uterus and pancreas were reported to occur more frequently among patients with diabetes [1]. However, it took some 70 years before the scientific community once more focused on this association. Several observational studies published over the last 10–15 years show unequivocally that there is an association between certain forms of cancer and type 2 diabetes. Figure 1 shows the relative risk for patients with type 2 diabetes to develop cancers by organ of origin. The relative risk appears to be highest for liver, pancreas and endometrial cancers [2–4]. There is also a 20–50% increase in incidence of breast, colon, kidney and bladder cancers [5–8], whereas cancer of the prostate actually appears to occur at a lower rate in these patients, although the outcomes of prostate cancer may be worse once established [9]. Indeed, it is a general finding that once the cancer has been diagnosed, the chance of dying from the cancer is higher in patients with diabetes than in patients without diabetes [10]. A difficulty in inferring a cause and effect relationship between type 2 diabetes and cancer is that both conditions are more prevalent with age and also with obesity. Obesity itself increases the risk of certain cancer forms, e.g. endometrial cancer, breast cancer, kidney cancer, colorectal cancer and pancreas cancer [11], and obesity itself also increases the risk of dying from the cancer disease [12]. It has therefore been postulated that the mechanism for cancer related to type 2 diabetes at least in part is a consequence of metabolic dysfunctional changes associated with obesity, insulin resistance, hyperinsulinaemia and also hyperglycaemia. The cancer rate is increased also in type 1 diabetes, but the cancer forms differ from type 2 diabetes in that the stomach, the cervix and the endometrium are the predominant sites in this condition [13].


Introduction : Tympanoplasty is the treatment of choice for chronic otitis media. In Chile, several studies have been carried out to evaluate the success of tympanoplasty. Here, we asse-sed the anatomical and functional outcomes, correlating the results with the demographics of our population. Aim : To carry out an epidemiological description of patients with a diagno-sis of chronic otitis media who underwent tympanoplasty at our hospital between 2017 and 2019. Material and Method : Retrospective, descriptive study. We reviewed clinical records of patients who underwent surgery between January 2017 and November 2019. This study has been approved by the ethics committee of Arauco health service. Results : 77 tympanoplasties were performed, of which 56 ears met the inclusion criteria. 71.43% were female. The age range is 8 to 64 years. 41% had chronic pathologies. 51.79% were left ear surgeries. 92.86% were type I tympanoplasty. An endoauricular approach was performed in 58.93%. A cartilage - perichondrium composite graft was used in 75% of the surgeries. A medial tech- nique was performed in 94.94%. Anatomical success was achieved in 85.71% of patients. An average gain over 10 dB was obtained in 60.71% of the patients. Conclusion : There were no significant differences regarding the surgical choices with the anatomical and auditory results.


In 1960s Rio de Janeiro, a multidisciplinary group of artists dedicated themselves to making art that invited active, sensory engagement from audience participants. This neoconcrete group theorized the art object as participatory and relational. The theoretical consequences of this approach to art-making included an expansion of the object's agency. No longer a static wall-hung work of art, the object was now capable of shaping the engagement of its human participants. Conversely, these participants would share in the object-like qualities of the artwork, merging with it in a relational exchange in which both the human and the nonhuman contributed to the constitution of the work. However, changes to this paradigm arise when the subject (or object) in question is not an abstract participant untethered to notions of gender identity. In Lygia Pape's work, objects are embodied and bodies are objectified, but, as she shows, this exchange cannot be separated from gender. This essay examines key works by Lygia Pape, including the Neoconcrete Ballet, Divisor, and Eat Me, and argues that her embodied aesthetics, rooted in twentieth century Brazilian art, chart new horizons for feminist posthumanism today.


Macrophytes are important elements of freshwater ecosystems, fulfilling a pivotal role in biogeochemical cycles. The synoptic capabilities provided by remote sensing make it a powerful tool for monitoring aquatic vegetation characteristics and the functional status of shallow lake systems in which they occur. The latest generation of airborne and spaceborne imaging sensors can be effectively exploited for mapping morphologically – and physiologically – relevant vegetation features based on their canopy spectral response. The objectives of this study were to calibrate semi-empirical models for mapping macrophyte morphological traits ( i.e. , fractional cover, leaf area index and above-water biomass) from hyperspectral data, and to investigate the capabilities of remote sensing in supporting macrophyte monitoring and management. We calibrated spectral models using in situ reflectance and morphological trait measures and applied them to airborne hyperspectral imaging data, acquired over two shallow European water bodies (Lake Hidvegi, in Hungary, and Mantua lakes system, in Italy) in two key phenological phases. Maps of morphological traits were produced covering a broad range of aquatic plant types (submerged, floating, and emergent), common to temperate and continental regions, with an error level of 5.4% for fractional cover, 0.10 m 2 m -2 for leaf area index, and 0.06 kg m -2 for above-water biomass. Based on these maps, we discuss how remote sensing could support monitoring strategies and shallow lake management with reference to our two case studies: i.e. , by providing insight into spatial and species-wise variability, by assessing nutrient uptake by aquatic plants, and by identifying hotspot areas where invasive species could become a threat to ecosystem functioning and service provision.


Culturally relevant programs among indigenous populations have had positive dietary outcomes, yet less is known about cultural immersion. This study examined the influence of cultural immersion on willingness to try fruits and vegetables (FV) among children 3‐12 y in Guam. A pre‐post, quasi‐experimental design was used to evaluate 3 summer camps with different exposure levels of cultural immersion. High, moderate, and zero exposure was provided by a cultural immersion camp (CIC), a university‐based day camp (UDC), and a recreational sports camp (RSC), respectively. CIC (n=47) delivered 4 culturally adapted nutrition lessons within the context of Chamorro cultural traditions. The UDC (n=23) delivered the same lessons within a physiology framework. The RSC (n=33) was without nutrition lessons and cultural immersion. Children's willingness to try FV was assessed with the interview‐administered WillTry tool before (± 2 weeks) and after (± 1 week) each summer program. Outcomes examined WillTry post‐scores using multivariate regression models adjusting for the relevant pre‐score, sex, age, ethnicity, dose, BMI, and parent's cultural affiliation. Post‐WillTry scores for local novel FV by highest exposure camp to lowest were 2.30, 2.33, 2.27. For local common FV, the post‐scores were 2.62, 2.61, 2.56, respectively. No differences by the primary outcomes were found. An unexpected result was the higher imported FV WillTry post‐score of 2.81 for RSC compared to the 2.75 for UDC (P=0.023). The Traditions study is the first to explore novel influences on dietary habits and reveals further research involving indigenous peoples and cultural immersion are needed.


The need to establish new cities emerged in the seventies of the last century in Egypt. The necessity emerged because of different reasons such as decreasing te pressure on greater cities and their infrastructure, creating new investments and job opportunities. Furthermore, it aimed to the rarefaction of the concentration of inhabitants around the narrow side of the Nile valley and its Delta. It even moved towards the vast desert in order to redraw the urban map of Egypt. So, the success of these new cities is measured by how much people they attract to settle and their input to local income according to general policies and goals which could be achieved through several strategies and mechanisms. Therefore, this research tries to discuss different policies in order to develop new cites, in particular, in addition to the efficient strategies and mechanisms which are necessary to decrease the consumption of resources and to achieve maximum benefits out of the available potentials.


Radiotherapy dose escalation has demonstratively improved progression-free survival and overall survival in prostate cancer patients. However, with ever increasing radiation doses the risk of concomitant injury to adjacent organs similarly increases. These risks are mitigated through improved technology and targeted therapy such as 3D conformational radiotherapy (3D CRT) and intensity modulated radiation therapy (IMRT). Colovesical and prostato-vesical fistulae are known complications of colonic biopsy post-radiotherapy in prostate cancer patients. However, spontaneous formation of colo-prostatic fistulae post external beam radiotherapy without prostate or bowel biopsy has not been previously reported. Herein we report two cases of spontaneous colo-prostatic fistula that were managed at our tertiary referral centre in the last two years. Neither of these patients had undergone any procedure, urethral or rectal, since their radiotherapy. Both patients had had only one transrectal ultrasound (TRUS) prostate biopsy prior to radiotherapy. Both patients presented with urine leak per rectum (PR). The fistulae were diagnosed on CT cystogram. Neither case spontaneously resolved with simple catheter diversion, and therefore required diverting colostomy and concomitant ileal conduit urinary diversion. Both patients recovered well at 6 month follow-up and have an improved quality of life despite double stomas. We believe that these cases serve as an important lesson to the potential complications of ever increasing radiotherapy dosing while attempting to improve oncological outcomes.


Abstract : The Hoelder continuity of sample paths of the following classes of stochastic processes is examined: (1) Processes satisfying Kolmogorov's moment condition, (2) self-similar stable processes with stationary increments and (3) harmonizable fractional processes.


This paper re-examines recent postal surveys of the stock of machinery in the metal-working industries of Britain, Germany, France, Japan and the United States. Japan has the youngest stock; Britain's stock has a lower average age than those in France, Germany and the United States. Numerically-controlled machines are rising rapidly in importance in all countries, but were less frequent in Britain and France. Questions are raised as to the unduly short-life of machinery assumed by national accounts statisticians; and suggestions are made for the improvement of future machine tool surveys.


Introduction: Injections with corticosteroids are one of the most  common non-operative interventions in the treatment of subacromial impingement syndrome. However, a systematic review conducted by the Cochrane Collaboration concluded that although ther e is evidence in support of corticosteroid injections, the effect ma y be no better than systemic NSAID. Although mildly successful, there are potentiall y serious side-effects of both injectable steroids an d oral NSAIDs. An alternative that has been tried some with some succ e s in the clinical setting is subacromial injection with Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) 6, . Theoretically, injecting NSAIDs would circumvent  is side effects of corticosteroid injections and or al NSAID treatment. There has been anecdotal evidence to suggest that s ub cromial injections of NSAIDs provide substantial pain relief and resto ra i n of shoulder function in impingement syndrome.


Above 65 kg empty BW, protein deposition is greater in pigs fed protein-restricted compared to standard diets. It is unclear whether the greater CP deposition rate in the finisher period results from the restricted CP supply in the grower period. To elucidate this question, a growth performance study (22.1-110.0 kg BW) was performed with 48 Swiss Large White pigs. They were assigned to either treatment C, LPF or LPGF. The grower-finisher diets of treatment C were formulated based on the Swiss feeding recommendations whereas those of treatment LPGF contained 20% lower digestible CP and essential amino acid levels than diets C. Pigs of the LPGF treatment were offered in the grower and finisher period the standard and the low CP diets, respectively. The pigs were reared in 1 large pen, equipped with 6 automatic feeders, which allowed measuring the individual ad-libitum feed intake per visit. The BW was determined weekly and carcass composition at slaughter was determined by dual-X-ray-absorpiometry. Growth performance and dual-X-ray-absorpiometry data were analyzed with a linear mixed model using treatment as fixed and litter, litter size and farrowing series as random effects. Despite total CP intake was 6 and 16% lower (P< 0.05) in the LPGF than the LPF and C groups, respectively, overall ADG among treatments did not differ. In accordance, gain-to-CP-intake ratio was 9 and 20% greater (P< 0.05) in the LPGF than the LPF and C group. The carcass protein content did not differ whereas carcass fat content was 9% greater (P< 0.05) in LPGF than LPF and C pigs. Carcass protein deposition efficiency was 0.5 and 6.7%-units greater (P< 0.05) in LPGF than LPF and C pigs, respectively. In conclusion, lowering the CP supply by 20% in the grower and finisher compared to solely the finisher period or not at all has no detrimental effect on growth performance, markedly improves CP utilization for carcass protein deposition but slightly increases carcass fatness.

The growing attention of sustainability agenda has led the development strategies on hazardous and toxic building materials identification for building construction industries. Unfortunately, the fragmentation and complexity of the construction process and involvement of many stakeholders resulted in lack of knowledge and information to manage the risks and hazards. There is a need for creating, converting, exchanging and sharing knowledge from scientific research findings with construction practices. For this study, a conceptual model was developed to assist the understanding on available building material information. This information model focuses on the initial effort to obtain baseline information on building material used and the possible risk management and mitigation strategies. Visible and accessible information on possible negative effects from building materials may assist decision making that could avoid and reduce potential deficiencies that may lead to increased adverse effects to health, safety or unforeseen death.


Splenic flexure volvulus is a rare cause of large bowel obstruction. Patients often present in a delayed fashion after the onset of peritonitis and require emergent surgical exploration. Here, we present a case of a subacute splenic flexure volvulus following previous low anterior resection and subsequent management.


Abstract The reaction of the diimine ligand 1,2-bis(1,3-diisopropyl-4,5-dimethylimidazolin-2-imino)ethane (BLiPr) with tetrameric [Cp*RuCl]4 in a 1 : 0.75 ratio afforded the complex salt [1][2] containing the 16-electron half-sandwich cation [Cp*Ru(BLiPr)]+ (1) and the dinuclear anion [Cp*Ru(μ- Cl)3RuCp*]− (2). The X-ray crystal structures of [1][2]·31/2THF (monoclinic, space group P21/n, Z = 4) and of [1][2]·THF (monoclinic, space group C2/m, Z = 4) are reported, allowing the structural characterization of the unprecedented anion 2, in which two [(η5-C5Me5)Ru(II)] moieties are bridged by three μ2-chlorine atoms.


This paper describes the application of a structural fire model, known as the Slab Panel Method (SPM), developed by the New Zealand Heavy Engineering Research Association (HERA) in conjunction with the University of Canterbury. The SPM accounts for the inelastic reserve of strength available from composite steel/concrete floor systems due to their two way deformation under fully developed fire conditions. The outcome of the performance based design process is a steel structure with fire proofing only to some of the steel beams supporting the floor. Structural elements which are critical for stability are protected with fire proofing materials, while the floor beams for which fire proofing is not necessary for structural stability or integrity are designed without this passive fire protection. This provides a structure which will remain stable for the expected temperatures and associated mechanical properties. Recent project examples where the SPM has been successfully used in New Zealand are reviewed. These include a 20 story 350,000 sq ft. office building and a 12 story 360,000 sq ft. mixed use office and apartment building, both under construction in New Zealand. Validation of one of the design solutions using finite element analysis to assess the actual performance for the range of structural fire severity expected is described. The paper concludes that design methods are maturing to a level where a dependable and robust performance can be predicted using the SPM, so that those parts of the structure which require fire proofing can be specified with enough protection to maintain structural stability, and those parts which do not need this passive fire protection can be safely constructed without fire protection. Opportunities for the application of SPM in the North American regulatory environment are discussed.


The scope of embryo research in the UK has been expanded by the Human Fertilisation and Embryology (Research Purposes) Regulations 2001. Two advisory bodies—the Chief Medical Officer's Expert Group and the House of Lords' Select Committee—presented various arguments in favour of embryo research. One of these is the view that, just as lottery tickets have relatively little value before the draw because of the low probability of their being the winning ticket, early embryos have relatively little value because of the presumed low probability that they will mature into more developed embryos. This (first) argument from probability is questioned in this paper, as well as the contention that allowing embryo destruction is incompatible with the view that embryos have full moral status. Although I challenge Savulescu's view that early embryos should be entered into a lottery in which they are subjected to the probability of being destroyed (the second argument from probability), a revised version of Thomson's analogy of the famous violinist defies the view that the position that the embryo has full moral status is incompatible with qualified support for embryo destruction.


The reinforcement principle, "We will like those who reward us; we will dislike those who punish us," was tested by comparing faculty evaluations and grades received by students. Data from a random sample of 37 courses suggest that the principle is valid, especially if it is reformulated as "We will like those whom we expect to reward us." Implications are discussed regarding design and use of faculty evaluations in colleges and universities.


We give a new and elementary proof showing that a homeomorphism f:X→X of a compact metric space is positively expansive if and only if X is finite.


PUBLISHED: 27 November 2019 Globally, ethics guidelines for conducting research involving human subjects have been informed by practices and procedures developed for, and with reference to, medical research.1,2 This indication is clear from international guidelines on research ethics practices, including the Belmont Report3 and the Declaration of Helsinki4. Historically, developments of guidelines in research ethics, and procedures for ethics review, have often been reactive responses to critical events (i.e. ethics breaches) in medical research practice. The context for research ethics and clinical practice changes continually owing to developments in technology and medical procedures including genetics and robotics. Thus, ethics guidelines for research involving human subjects often lag behind developments in technology and medical science. Despite such guidelines, there are limitations as to the extent to which they can be applied to research that involves human subjects but in non-medical and non-therapeutic settings (here termed human participants). In this context, the term non-medical refers to the application of social science and humanities methodologies and instruments relating to human participants outside of medical, clinical or therapeutic settings. This type of research includes data collection using qualitative and interactive methods, such as interviews, questionnaires, workshops, focus groups and ethnographic observations.


In axisymmetric irrotational flows of a perfect fluid under gravity there are three basic conserved quantities; axial momentum, energy and a circulation based, radial moment of momentum. This paper adapts these conservation principles to describe cavity collapse adjacent to a rigid boundary in a semi-infinite perfect fluid. They afford a global model accounting for volume change, migration and jet formation; physically the most significant features of bubble collapse close to a rigid boundary.


This work evaluates the effect of graphene, indium tin oxide (ITO) and Ni/Au as contact/current spreading layer/current spreading layer for GaN vertical light emitting diodes (V-LEDs). In this simulation study, the effect of these contact/current spreading layers on different performance parameters of GaN V-LEDs has been studied. By using these three different types of contact/current spreading layers, we have comparatively studied the effect on light extraction efficiency (LEE), optical output power, wall plug efficiency and radiant intensity of V-LEDs. As per the simulation results, it shows that using graphene contact/current spreading layers, it is possible to achieve better performance than using ITO and Ni/Au contact/current spreading layers. For graphene/(Ni/Au) contact/current spreading layers, the LEE is improved by 36.77% whereas for ITO/(Ni/Au) contact/current spreading layers it is improved by 13.74%. Also, by using graphene/(Ni/Au) contact/current spreading layers, the optical output power of LEDs improved by 11.11% whereas for ITO/(Ni/Au) contact/current spreading layers shown 4.16% improvement. The radiant intensity is enhanced by 37.65% for graphene/(Ni/Au) contact/current spreading layers and 13.5% for ITO/(Ni/Au) contact/current spreading layers. In this report, we have given a detailed analysis of the obtained simulation results. The simulation was carried out in SimuLED tool.


The emission of spin-0, 1, and 2 waves by particles moving with ultrarelativistic velocity along circular geodesics in spacetime described by the Kerr metric is studied. The method of reducing the Teukolsky equation to an equation with a real effective potential is used, which makes it possible to obtain wave fields of nonzero spin by differentiating the scalar field. Analytic expressions for the spectra and multipole distributions of the fields are obtained and analyzed and the results are compared to the corresponding characteristics of synchrotron radiation in flat spacetime. It is shown that a black hole absorbs exactly half of the emitted radiation intensity and a qualitative interpretation of this phenomenon is suggested.

The last decade has seen the rise of a self-described worldwide "movement" of fact-checking groups which specialize in debunking false political claims and other forms of misinformation. This very heterogeneous movement now spans nearly 300 fact-checking outlets in more than eighty countries, led by their own professional organization. This study charts the emergence and development of this transnational institutional sphere with qualitative and quantitative analysis of the annual summit of fact-checking organizations, Global Fact, as a field-configuring event (Lampel & Meyer, 2008). Drawing on ethnographic fieldwork by two authors as well as comprehensive data on the first six Global Fact meetings, we use shifts in the structure and content of the event to explore processes of structuration; we highlight a shift from a field-building ethic valuing inclusiveness and celebrating diversity to one valuing common practices and standards, marked by new governance mechanisms and increasing interest from powerful outside stakeholders. Ultimately, our data show the fact-checking field negotiating a necessary tension between managing internal diversity and consolidating as an increasingly recognized institutional actor in the domain of public communication.


This paper puts forward a reconstruct method accordingly based on different features of data set. That is, an algorithm of surface interpolation is achieved. The knots vectors are established, via Accumulative Chord Length method. So the precise surface can be attained.


3D printers are increasingly used after the spread of the COVID-19 pandemic. This machine was used to overcome the lack of medical devices and personal protective equipment. In order for printed objects to be useful in the medical field, the mechanical properties of these objects must be known. The main objective of this study is to assess the mechanical properties of parts manufactured in polylactic acid by a 3D printer machine. The mechanical properties are determined from the experimental results of the three-point bending test. The results obtained show that the mechanical properties depend on the process parameters. The analysis of variance was used to determine the printing parameters that have a statistically significant effect on the mechanical properties. The optimal printing parameters are determined to manufacture parts with high mechanical performance and used them in complete safety. The finite element analysis was performed using ANSYS mechanical APDL software to validate the experimental results.


In connection with his investigations on the isotope shift in the band spectra of ionized mercury hydride, it has become necessary for Mrozowski to investigate the hyper¬fine structure of certain ionized mercury lines. He has re¬cently reported his results' regarding the analysis and the interpretation of the structure of some ionized mercury lines. Reference has been made by him to a short note in which the structure of X3984A had just been mentioned by Venkatesachar and myself ;2 but it is unfortunate that Mrozowski seems to be quite unaware of our subsequent detailed paper' on the "Hyperfine structure of some HgII lines," in which the structures of XX3984, 2848 and 2262A had been investigated as early as in 1934. Mrozowski's results in regard to the structure as well as the scheme of hyperfine levels of the line X3984A agree with our earlier findings. Mrozowski, just like ourselves, has been unable to confirm the satellite at +1.950 cm-1 reported by Murakawas earlier, and it is now certain that no such satellite exists. The total spin separations of the two levels 6 2P3/ 2 and 5d9 6s2 2D512 given by Mrozowski agree with those previously determined by us and are consistent with theoretical expectations based on Goudsmit's formulae.' The scheme of hyperfine levels worked out by us for ex¬plaining the observed structure of the line is identical with the scheme proposed by Mrozowski; the agreement in the nuclear spin separations of the upper and lower levels.


One of the important things in the management of parking is about the problem of protection for consumers of parking service users about the security of vehicles and goods deposited in the parking area. Most parking attendants and parking service managers are not to blame in the event of loss of consumer goods. The menager of the parking service always uses the reason that it is in accordance with the agreement or binding clause between the manager and the consumer that has been stated in the parking ticket, "The parking Manager is not responsible for the loss of goods or vehicle." Any binding clauses which have been made between a business actor or a parking service manager are prohibited as in Article 18 of the Consumer Protection Law. The purpose of this study is to explain the validity of the standard clause as an agreement in the terms of the legal provisions of Article 1320 of the Civil Code Law and the principle of contract law and to describe the legal protection for parking service users against the use of the standard clause in the parking ticket at the Ministry Surakarta City based on the Consumer Protection Law. In this study the authors use empirical legal approach that is the research used to solve problems by conducting primary data research in the field. Type of research used by the author in this research is descriptive research with document study method and field method which analyzed by the deductive logical analysis.


Significant research efforts for robust integration of information from multiple sources are being pursued at a rapid pace. However, the information in heterogeneous sources is often incomplete and hence making the maximum use of all the available information is a challenging problem. Most of the recent research on data integration have been primarily focused on the cases where the information is available across all the different sources and can not effectively integrate sources in the presence of partial information. We develop an ensemble method that boosts the decisions made from different models on individual sources and obtain robust results for the task of class prediction. We propose a heterogeneous boosting framework that uses all the available information even if some of the sources do not provide any information about some objects. We demonstrate the effectiveness of the proposed framework for the problem of gene function prediction and compare to the state-of-the-art methods using several real-world biological datasets. We also show that the proposed method outperforms any kind of imputation schemes that are widely used while integrating data with partial information

The article is devoted to the study of the relationship between the revolutionary events in the Arab world in 2011-2014 and the growth of migration flows from the Middle East. Migration processes in the modern world are becoming more widespread, affecting both the domestic policy of the countries and foreign policy relations. The aim of the research is to study and identify the factors, trends and features of modern migration processes from the Middle East to the EU member-states, as well as to assess the socio-economic consequences of migration. The relevance of the research is determined not only by the increased social significance of the phenomenon of migration in the context of globalization, but also by the complexity, diversity of problems associated with it. To study the phenomenon of migration, an integrated, interdisciplinary approach was applied. This work introduces new information about the specifics of migration processes from the Middle East to European countries into scientific circulation and political practice. The author comes to the conclusion that with the beginning of the «Arab spring» forced and illegal migration has become predominant, which in Europe has led to the deterioration of social security and the economic situation. The study has showed that the nature of migration has changed significantly due to the spread of the threat of international terrorism. In view of the significant changes in migration processes related to terrorism, the attitude towards migrants has changed significantly, and the migration policy of the countries has adopted tougher measures towards foreigners.


Our research was aimed at developing methods and algorithms for identifying and mapping fracture zones of the Jurassic and pre-Jurassic complexes based on seismic data and methods of machine learning and artificial intelligence. In this paper it were developed and tested: the feature selection algorithm based on an autoencoder for interpreting data on seismic slices with low intraclass and high interclass variability, as well as the algorithm for synthesizing new images based on generative adversarial networks and a seismic database. The experiments carried out have shown that the algorithms have good accuracy and speed of operation, which makes them potentially suitable for processing large volumes of seismic information. The proposed autoencoder for candidate images with a high recall value both for the search variant with the micro-averaging metric and for the search with the macroaveraging metric. The automatic interpretation of seismic data on seismic slices of the Salymskaya well was carried out. The system for processing, analyzing and classifying 3D seismic information was developed based on the proposed methods and algorithms. The optimal predictive model was tuned based on machine learning and artificial intelligence methods.


Avalanches pose a significant threat to human life and settlements, hence their study is key in formulating settlement risk zones. Validating models of avalanches, developed to predict their behaviour, are limited by the quality of current field data. Radar measurements of avalanches have been made, however these measurements suffer from coarse 50 m, single dimensional localisation. This work describes the design and installation of a sophisticated FMCW phased array radar with sub-metre range resolution for imaging avalanches. With this radar, we aim to provide a high quality, 2-D, animated reconstruction of avalanche events. The radar is currently installed in a bunker at a well-equipped avalanche test site; Vallde la Sionne, Switzerland. It will operate throughout the 2010/11 winter, automatically recording data when a natural avalanche event occurs. Indeed, a wet snow avalanche has already been recorded on the 7 th December 2010. A sample output from the data recorded during this event is shown in this paper in the form of a range-time image. The data gathered during this event will be further exploited using sophisticated radar signal processing algorithms. We hope also to analyse micro-Doppler signatures of the component blocks of snow in the avalanche.


Objective: evaluate the efficacy of 10% sodium ascorbate hydrogel as desensitizer after bleaching. Materials and methods: in this clinical case, a volunteer was selected with the inclusion and exclusion criteria. Tooth whitening was performed with 35% hydrogen peroxide (Whiteness HP, FGM) in two sessions of 45 minutes (each session with 3 gel applications of 15 minutes). Dental sensitivity was evaluated with the VAS scale and 5 points scale; Subsequently, the desensitizing agent (10% sodium ascorbate) was applied on the buccal surface for 10 minutes, finally it was removed and the sensitivity was evaluated. Results: during the first bleaching session, the patient reported sensitivity at the end of second and third applications, and the symptom lasted 48 hours; for the second bleaching session tooth sensitivity appear at the end of the procedure and also lasted 48 hours; The sensitivity referred by the patient was between mild and moderate. After the treatment occurred tooth whitening of 6 shades for the central incisor and 7 shades for canine according to the EASY SHADE. Conclusions: the application of 10% sodium ascorbate hydrogel after tooth whitening as a desensitizing agent, does not prevent post-whitening sensitivity. Recommendations: It is recommended to make clinical studies that evaluate the efficacy of this agent to prove the true effect on sensitivity.


John II Komnenos was the son of Emperor Alexios I Komnenos and Eirene Doukaina, and brother of Princess Anna Komnene, the author of the Alexiad. Born in 1087, he was crowned soon after his fifth birthday as co-emperor with his father, and in 1105, he was married to Piroska Árpád, daughter of King Ladislaus I of Hungary and Adelaide of Rheinfelden. He is principally known for continuing his father's work of stabilising Byzantium after the crises of the eleventh century. This included major wars of defence and conquest in both the Balkans and Anatolia, and especially a major eastern expedition in 1137–1139. During this campaign, he conquered Cilicia, but he was recalled to defend his borders against the Turks before he could make further conquests in Syria and bring the crusader states under his aegis. He died in a hunting accident just before he returned to Syria, with intentions to go to Jerusalem as well. His best-known iconographic representation is a mosaic of him and his wife in the Great Church of Sophia. Whilst there is also an image of him in a contemporary ornate gospel book, his most common representations are found on his many coin issues and seals.


Objective: to study the possibility to change the working behavior of employees by actualizing their motivational potential. Methods: the methods of survey, questionnaires, focus groups, coaching and interview were used in the study. Results: the studies have shown that the employees' motivational potential is revealed through a complex system of labor motivation, taking into account the needs and interests of a particular employee and forming the motivational and stimulating environment. Scientific novelty: the research includes the development of methods to analyze the employees' interests and dominant motives and building of the structural system of employees' motivation to effective action. Practical value: developing a method to increase the employees' motivation for efficient work in the form of a systematic set of actions. The application of this method allows to increase the efficiency and productivity of workers, to gain additional profit, which is especially important in the context of the economic crisis and the lack of additional investment.


We study an online retail marketplace's incentive to manipulate sellers' product attractiveness to consumers (e.g., through fake sales, fake reviews, or dishonest endorsement) and sellers' placement ranking.


The femtosecond stimulated Raman process is a versatile technique to excite rotational states in molecules. We demonstrate control over the rotational state population in a sample of NO molecules by varying the time delay between two identical laser pulses. The product of the rotational state distribution is probed by a 1+1 resonance-enhanced multiphoton ionization scheme and simulated quantum mechanically. There is good agreement between theoretical and experimental results. The product in selected quantum states shows an oscillatory dependence on the time delay. Spectral analysis reveals rotational transition energies and the presence of multiple Raman steps. We show that the relative strength of these frequency components can be related to excitation pathways with predominant J=2 transitions toward higher rotational states. The initial step from J=1/2involves either J=1 orJ=2. We find that one can discriminate between two excitation ladders. The results demonstrate the coherent effects of tailoring the shape of an ultrashort excitation pulse.


ABSTRACT The COVID-19 pandemic is an unprecedented event which is transforming societies and strengthening the bond between human and technology. However, less attention is paid to nonusers of the Internet. To combat the pandemic, the Polish government introduced, in June 2020, a new policy that made it possible for citizens who had lost their job as a consequence of the crisis to obtain financial support. The application for this allowance was, however, possible only via an online platform. The paper discusses how this violated the right of the unemployed to stay offline.

The large-scale hybridization of fishes of the subfamily Leuciscinae in the subordinate systems of the Dnipro River basin is presented by the data on two pairs of species, roach Rutilus rutilus × bream Abramis brama, and bleak Alburnus alburnus × rudd Scardinius erythrophthalmus. The hybridization and occurrence of F1 hybrids are confirmed with allozyme spectra and morphological characters on series of samples. A complete morphometric analysis of the characteristics of bleak and rudd hybrids was performed. The paper discusses the intergeneric hybridization in nature, which is a unique phenomenon characteristic only of some groups of cyprinids. The most likely reason is the overestimation of the taxonomic status of European cyprinids, which is confirmed by the insignificant level of intergeneric genetic divergence.


Lee Jang-Hee is noted for his imagism poems. His poems are based on a heartbreak and a sadness. This is similar to other poets' poems of that age. But other poets expressed their sadness, tears, heartbreak exaggeratingly. Lee Jang-Hee was temperate in expressing his feelings and tried to describe the thing in itself. Owing to that feature, Lee Jang-Hee's poems are evaluated as the initiative of modernism poems in 1930s. 'The Scenery of One Summer Day' is a poem that describe the things and affairs. The poet observed the things accurately and described it as if it is the real. But 'Spring is a cat' is consisted a observation and a poet's thought. The cat of this poem isn't a real cat but a thinking toward a cat. Lee Jang-Hee connected the characteristic of a cat with a special feature of spring. Image is not only copying the objects but also interpreting them. And Lee Jang-Hee made the complex image. It was consisted different senses. For example, the visual and a sense of touch, the sense of smell. He objectified his sentimental feeling by making images. As a result, he could overcome sentimentalism and use poetic words economically. Lee Jang-Hee's poems are based on the thought that poetry is not natural overflow but well-made thing. This thought is a very important turning point in Korean poetic history.


Six sets of unrelated healthy individuals, phenotypically "identical" in each set for the four antigens of the two HL—A segregant series, were tested with 153 antiplatelet antisera by microcomplement-fixation. In five of the six sets the results unequivocally show that the individuals were not identical by complement-fixation reactions. It is proposed that sera which manifest nonidentity between individuals within these sets identify either "variants" of the known HL—A antigens or antigens of a third segregant series of the HL—A system or of a non-HL—A system. Accurate and complete matching for HL—A antigens among unrelated individuals will require further definition of specificities.
