Specimens for this study were collected in the ecotonal regions between tropical deciduous forest and arid thorn scrub in southwestern Tamaulipas. This taxon is not common in riparian habitats. Captive breeding behavior for four pairs of Agkistrodon bilineatus taylori was observed between September and February. Young were born between June and November. Male combat behavior typical for several members of the genus Agkistrodon was observed on several occasions among five different pairs of captive male specimens. One instance resulted in death for one of the participants. Young are less colorful than adults; dramatic ontogenetic color changes exist in this taxon. Females typically have more ornate patterning and interstitial markings than do males. Both sexes become nearly black as old adults. The LD50 for A. b. taylori venom is 47 micrograms (I.P.) per 20 gm mouse.

The performance and efficiency of different variable speed drives are described and compared in this paper. The selection method of a variable-speed drive system is presented taking into account the minimizing total investment and exploitation costs. A partial elimination of weather regulators in heating nodes is proposed.


Existing finite automata public key cryptosystems (FAPKC) are analyzed in this paper. General types of cryptanalytic attacks on FAPKC are discussed and methods of breaking FAPKC by some known types of attacks are introduced. The times needed to perform the usual cryptanalytic attacks on FAPKC are calculated, in order to estimate processing complexity of those attacks. The contrastive analysis of performed attacks' processing complexities is made to compare the vulnerabilities of FAPKC against discussed attacks. As a result, an improved FAPKC is designed in order to resist the presented types of attacks. Strong FAPKC is obtained by generating invertible nonlinear and linear automata of the suitable form.


Objective To evaluate the efficacy of pylorus-preserving gastrectomy(PPG) in the treatment of early gastric cancer(EGC).Methods We reviewed the clinical data of 22 consecutive patients with EGC who received PPG treatment in our department from September 2007 to October 2009.Twenty two cases were all the early stage of gastric cancer,with 16 lesions located in the middle and the other 6 in the lower third of the stomach,all lesions were more than 5 cm above the pylorus,and all of which were applicable to PPG treatment.Results There were no patients with postprandial symptoms during their postoperative stay in hospital,but twenty of them had hunger feeling(90.91%).During the follow-up study,two patients suffered postprandial symptoms,one of whom had upper abdominal distention and pain,and the other vomited.Eighteen patients had hunger feeling(81.82%).Conclusions This study indicated PPG procedure is a good technique in the treatment of EGC of the middle portion of the stomach.It has ideal radical effect as well as satisfactory functional preservation of pylorus,which can be of benefit to patients′ rehabilitation.


The first 2D metal-organic framework utilizing PPh2(CH2)2PPh2 (dppe) units as the linkers and tetranuclear silver clusters, [Ag4(micro3)-Cl){S2P(OR)2}3], as the network nodes in the formation of the honeycomb-shaped layer structure is reported.


In the past, the same fistulotomy (lay-open procedure) used to treat intersphincteric fistula was also used to treat ischiorectal fistula and supralevator fistula. However, when the lay-open procedure was performed on ischiorectal fistula and supralevator fistula there was a possibility that the rectum would shift forward and the number of postoperative in-continence cases would increase. When anal function was manometrically examined after the lay-open procedure was performed on low intersphincteric fistula there was a significant reduction in the maximum resting pressure of the lateral lay-open procedure compared to the posterior lay-open procedure. Moreover, the results of a questionnaire to ascertain the degree of anal sphincter tension one year after the lay-open procedure was performed on the anterior, lateral and posterior sides of the low intersphincteric fistula revealed that 24.3 % of the anterior cases, 54.9 % of the lateral cases, and 16.4 % of the posterior cases reported low tension. In other words, sphincter function was greatly influenced when an anal sphincter-otomy was performed. Judging from these results, even with the Hanley technique, there is a strong possibility of impairing sphincter function when the lay-open procedure is performed from a posterior lesion to the primary orifice on the dentate line. Therefore, the sphincter-preserving surgical procedure is recommended for ischiorectal fistula and supralevator


In this paper we present the methodology to predict the value of the complex optimality criteria from the parameters of the oil field development system such as well spacing, the distortion factor, the type of well completion, the horizontal length of the end of switching time, etc. The method presented in this paper is based on the results of multivariate calculations in a hydrodynamic simulator and the use of correlation models of machine learning (ML).


This paper presents a method for actively controlling dynamic reaction forces in flexible structures subject to persistent excitations. The motivation is provided by applications in which dynamic loads result in structural or machinery failures (for example, in the bearings of rotating machinery), or in situations where transmitted vibrations degrade the performance of a system or process. This work is a deviation from much of the vibration control work which focuses on suppressing structural displacements instead of forces.
 The controller is based on an adaptive feedforward disturbance cancellation scheme which has come to be a commonly used method among researchers for persistent disturbance cancellation. In order to use that method for control of forces, however, some modifications are necessary. First, since reaction forces are not typically measured in structures, a Kalman filter state estimator is developed to provide the reaction force signal to the feedforward algorithm, and second, the residual flexibility matrix is used in conjunction with the Kalman filter in order to provide accurate force estimates in spite of a reduced-order model. This paper presents the development of the reaction forces, the Kalman filter estimator, and the hybrid feedforward control law, and applies the overall method to a flexible beam test rig to suppress the dynamic reaction forces at its supports.


We describe how the material properties of III–V semiconductors, including bandgap, band structure, band offset, refractive index, absorption, and ionization coefficient, are exploited for lasers and photodetectors for fiber-optic communications. The material systems discussed for 1.3 µ m and 1.55 µ m light emission include the more traditional GaInAsP and AlGaInAs on InP, the more recently investigated GaInAs quantum dots and low-bandgap GaInNAs on GaAs as well as GaAsSb/GaAs Type II structures, and the potentially viable GaN/AlGaN from intersubband transitions (i.e., between quantized conduction-band energy levels). As an example of photodetector applications, GaInAsP/InP and wafer-fused GaInAs/Si are discussed in terms of gain and noise factor for use in avalanche photodiodes with separate absorption and multiplication regions.

Objective:  Duration of untreated illness represents a potentially modifiable component of any diagnosis‐treatment pathway. In bipolar disorder (BD), this concept has rarely been systematically defined or not been applied to large clinically representative samples.


In this study, I have attempted to solve two subjects by introducing Taejon-shi as a case study like the following ; First, if the migration field exists in a city concerning the structure of the migration or not. If it does what does the pattern of it look like? Secondly, can we grasp socio-economic characteristics of the intra-urban migration on the ground of the Berry's Geographical Field Theory? And if it is possible, what kind of characteristics do they represent? To solve the first problem, the destination and origin factors of intra-urban migration and their spatial patterns were investigated and to solve the second problem the factors of the urban socio-economic characteristics and their spatial patterns were investigated too. As a theoretical background analyzing these things, I used an urban residential structural approach with emphasis on inter-relationships between the homogeneous region and the nodal regi on. The main methods to analyze such problems are R-mode factor analysis, Q-mode factor analysis, and canonical correlation analysis. The data used here assume the form of the transaction matrix of migration and socio-economic geographical matrix. In case of investigating the structure of the migration, the findings can be summarized as follows : First, the seven destination migration factors were extracted, and their spatial patterns shows that most destinations are omnipresent adjacent to the fixed part(expecially, eastern district). Secondly. the six origin migration factors were extracted and their spatial patterns show characteristics similar to the destination migration factors. Thirdly, the six intra-urban migration fields were confirmed ; Yucheon 1ㆍYucheon 2ㆍDomaㆍMunwhaㆍKajangㆍSanseongㆍOryu-dong Field, Munchang 1ㆍMunchang 2ㆍDaesaㆍBusaㆍDaeheung 3ㆍSeongnam 2-dong Field, Muuchang 1ㆍMunchang 2ㆍDaesaㆍBusaㆍDaeheung 3ㆍYongjeonㆍDae 1ㆍSinheungㆍPanam-dong Field, Hoedeuk 2ㆍYongjeonㆍSeongnam lㆍSeongnam 2ㆍSozaeㆍSamsung 2ㆍJungdong Field, MokㆍSeonwha 2-dongField, Hoedeuk 1ㆍOjeongㆍDaewhaㆍMunji-dong Field. In case of investigating the socio-economic characteristics of the migration, the findings-can be summarized as follows ; First, on the whole, the intra-urban socio-economic characteristics are manifested in five common factors. The factors are suburbs and newly-developed district characteristics, manufacture district characteristics, residential district characteristics. central business district characteristics(C.B.D. characteristics), and sub-C.B.D. characteristics. The spatial pattern of these factors manifest socio-economic characteristics of respective district exactly. Secondly, the socio-economic characteristics of destination migration factors are such that the first factor and the manufacture district characteristics, the second factor and the residential and central business district characteristics, the third factor and the residential district characteristics, the fifth factor and the suburbs and newly-developed district characteristics, and the sixth and seventh factors and the sub-C.B.D. characteristics, have strong inter-dependency, respectively. The fourth factor and the characteristics of suburbs, newly developed and central business district have weak relationship of interdependency. Thirdly, the socio-economic characteristics of origin migration factors are such that the first factor and the manufacture district characteristics, the third factor and the manufacture and central business district characteristics, the fourth factor and the sub-C.B.D. characteristics, and the fifth and the sixth factors and the characteristics of suburbs, newly developed and central business district characteristics, have strong interdependency, respectively. With the above analysis, I confirmed that characteristic migration fields exist in the intra-city of Taejon, and also destination and origin migration factors have distinct socio-economic characteristics. In the course of the analysis, it was also confirmed that the factor analysis and the canonical correlation analysis are effective, and that the Beny's Geographical Field Theoretic Approch is also effective especially to investigate the socio-economic characteristics of migration. The study such as this should be developed into the prediction about the structure and socio-economic characteristics of migration. Also, it should be applied to larger scale of district.

INTRODUCTION: Cryptococcus neoformans and Cryptococcus gattii are encapsulated basidiomycetous yeasts with worldwide distribution. They cause cryptococcosis with features of systemic infection, affecting the central nervous system, lungs and skin in humans and animals. These fungi present numerous virulence factors that allow them to invade the host and multiply, among which extracellular enzyme capacity and microbial adaptation to different temperatures are worth mentioning. OBJECTIVE: To evaluate the production of protease and investigate possible differences in thermotolerance and urease activity in clinical and environmental yeast isolates. MATERIAL AND METHODS: Culture methods and Pz analysis were applied to assess urease and protease, whereas the optical density method was used to analyze biological activity in thermotolerance. RESULTS: There was no significant results as to microbial growth at the tested temperatures (25o, 37o and 42oC). It was observed that clinical specimens grew better than environmental ones at elevated temperatures. As to C. neoformans, the moderate production of urease enzyme prevailed in both clinical and environmental isolates within 24h or 48h. Moreover, there was significant production on the seventh day of reading. The best reading time for viewing protease production in both isolates and species was the seventh day: 96% clinical samples and 94% environmental isolates. CONCLUSION: Further studies are required in order to investigate the virulence factors of C. neoformans and C. gattii cerebrospinal isolates from patients with meningoencephalitis and environmental samples from Sergipe. Furthermore, a higher technical accuracy and statistical precision are indispensable.


Right from the start, the countries of Central and Eastern Europe embarked on a hugely ambitious path of reform. Leaving aside differences across countries, a long and challenging process of economic transformation brought countries in the region significant improvements in incomes and living standards. Full membership of the EU – or the prospects of accession – provided an important stimulus for the process of transformation as well as an anchor of stability.

Objective: to determine the ability of integrative assessment of the family in a group of resident doctors in Family Medicine. Methods: observational, cross-sectional and comparative study for which it was developed and validated an instrument that explores the ability of an integrative assessment of the family. Its internal consistency was calculated with the Kuder-Richardson 20 test after a pre-sampling, the U of Mann-Whitney was used to compare the two halves of the instrument (semi-partition) and to confirm if there is or there is not difference between them. The number of possible answers expected were randomly determined with the Perez-Padilla and Viniegra test. Finally the instrument evaluated 49 residents in Family Medicine from the three years of an academic office. Results: the internal consistency of the instrument was 0.9. When comparing the two halves, it was obtained a p=0.47. Applying the instrument, 65% of the sample had low grade, 25% in very low grade and 10% in the intermediate. There were no statistically significant differences between the three assessed grades (p>0.5). Conclusions: the elaborated instrument is valid and reliable. Ability to integrative assessment of the family in residents doctors is little developed, regardless of the years of experience, so it is necessary a change in teaching, based on more effective educational strategies.


The coherence of the fuel injection quantity determines the working stability of the common rail system. The variations in the parameters of the common rail injector have significant influence on coherence of the fuel injection quantity of the system. The bond graphs for the main components of the common rail injector were proposed, respectively, based on the bond graph methodology in this article. The fuel injection quantities of the system at different rail pressures and injection pulse widths had been obtained by numerically solving and programming the obtained state equations in MATLAB. The predicted results of the fuel injection quantity by the model are in excellent agreement with the experimental measurements which were obtained from a test bench. Through the correlation analysis of the influential factors on the fuel injection quantity, the correlation coefficients between the fuel injection quantity and the single influential factor and quadratic influential factor at different rail pressures and injection pulse widths were obtained, respectively. Moreover, the variation characteristics of correlation between the fuel injection quantity and its influential factors had been analyzed in detail. The results show that the nozzle hole diameter and the inlet orifice diameter are the main influential factors on the fuel injection quantity among the selected parameters. The quadratic factors under the action of the parameter itself and the quadratic factors under the interaction between the delivery chamber diameter and nozzle hole diameter, needle seat semi-angle and needle cone semi-angle, nozzle hole diameter and inlet orifice diameter and inlet orifice diameter and outlet orifice diameter have significant effect on the fuel injection quantity, and they are the main influential factors on the fuel injection quantity among the quadratic factors.


The effect of FeOxand SnOxadditives on the catalytic performance of MnOx-CeO2 supported on activated carbon honeycomb( MnOx-CeO2/ ACH) in NO removal at lowtemperature was investigated. The results indicated that the addition of FeOxcan improve the distribution of manganese and cerium oxides on the ACH support and enhance the resistance to SO2 poisoning in NO removal; the activity of FeOx-modified MnOxCeO2/ ACH increases with the increasing reaction temperature from 80 ℃ to 200 ℃. Meanwhile,the MnOxCeO2/ ACH catalyst modified with SnOxexhibits high NO removal activity and good resistance to SO2 poisoning at relatively high temperatures; over SnOx-modified MnOx-CeO2/ ACH at 250 ℃,NO conversion decreases slightly from 98. 6% in the absence of SO2 to 87. 8% in 700 min upon the introduction of SO2 in the feed.


This paper discusses the design of configurations of videophone equipment aimed at online sign interpretation. We classified interpretation services into three types of situations: on-site interpretation, partial online interpretation, and full online interpretation. For each situation, the spatial configurations of the equipment are considered keeping the issue of nonverbal signals in mind. Simulation experiments of sign interpretation were performed using these spatial configurations and the qualities of the configurations were assessed. The preferred configurations had the common characteristics that the hearing subject could see the face of his/her principal conversation partner, that is, the deaf subject. The results imply that hearing people who do not understand sign language utilize nonverbal signals for facilitating interpreter-mediated conversation.


Purpose of the study: to study the reasons for seeking outpatient medical care for patients in whom, after death, the code R-54 (old age) is indicated in the medical death certificate (MCD) as the initial cause of death (PPD).Materials and methods of research. Data from the electronic database of the Main Department of the Civil Registry Office of the Moscow Region (USR registry office system of the Moscow Region) and electronic medical records (EMC) from outpatient clinics of the Moscow Region for 2020–2021. In total, 1,269 cases were registered in the MSS with the code R-54 (old age) indicated in the MCD as a PPD, of which 987 (77.7 %) sought outpatient medical care. Data included gender, age, 4-digit ICD codes for all reasons for referrals.Results. The mean age of the deceased was 87.7 ± 4.7 years (minimum 76 years, maximum 103 years; 1.4 % under the age of 80; females 88.08 ± 4.7; males 86.59 ± 4.6 p < 0.001). In 4 of the deceased, IHD was indicated as other causes contributing to death (part II of the MCD). On average, there were 3.77 ± 3.98 (men 4.2 ± 3.6 and women 3.6 ± 3.3; p = 0.04) reasons for visiting, indicated by 4-digit ICD codes. IHD group codes were registered in 21 %; AG 38.5 %; codes of the group "cerebrovascular diseases" – 25.3 %; cancer – 6.8 %; 5.1 % diabetes mellitus; 9.8 % – COVID-19. Among those who registered one reason for contacting (25 % – 1 4-digit ICD-10 code), 70 % applied for diseases, the rest of the reasons for contacting belonged to the codes of groups R, S and Z.Conclusion. In the overwhelming majority of cases, the R-54 code in the MCD is used unreasonably. However, taking into account the position of the WHO set out in the ICD and data from other countries, it is necessary to clarify the criteria for the use of both this code and other vaguely defined terms and codes that are used in the MCD as PPD.

Objective: to establish whether an echocardiogram is always necessary when investigating heart failure (HF) in elderly patients. Method: a clinical assessment was compared with echocardiography in 51 elderly patients aged S75 years complaining of breathlessness of more than 1 month's duration. Results: the greater the number of clinical features of HF present, the more likely was echocardiography to reveal a potential cause. It revealed a potential cause of HF in all 16 patients with strong clinical evidence (four or more features present). Of the 20 patients in whom clinical evidence of HF was equivocal (two or three features present), the echocardiogram revealed a potential cause of HF in nine and so was valuable in directing the diagnosis towards or away from HF. In only two of the 15 patients with minimal clinical evidence of HF (one feature or less) did the echocardiogram reveal a potential cause of HF. Severe valvular lesions were common, occurring in 20 (39%) patients. These were difficult to identify clinically as clinical features were non-specific and murmurs were not always present. Conclusions: echocardiography is most useful in those elderly patients in whom the clinical diagnosis of HF is uncertain or for whom valvular surgery might be considered.


The estimation of aquifer parameters by solution of the inverse problem has considerable attraction to groundwater hydrologists as an alternative to the traditional pump test. However, because of the fundamental instability of inverse problems there are several traps into which the user may fall. The paper presents a systematic treatment of the general ideas behind numerous methods for solving inverse problems from the literature of groundwater hydrology. Principles are developed for the best available approach to these problems.


The majority opinion makes no effort to explain how we as a society should confront this core one-sidedness of information. This is hardly just an antitrust problem. We will constantly confront information that is systematically more available to one side more than the other, and we will see that in cases across the board, including the discrimination cases that receive some attention in todayA¢â'¬â"¢s opinions.

Wound healing is a process by which skin or body tissue repairs itself after a trauma. In some cases, where the predicted time of wound healing due to health conditions such as hypertension, anemia, diabetes, etc., the wound is defined as a chronic wound. Coal Tar (5% topical application for 10 days) was evaluated for its wound healing activity in albino rats using excision wounds. The rats were divided into three groups: (a) without treatment, (b) with petroleum jelly (Vaseline) and (c) with 5% coal tar. Inter-group comparisons were made using one-way analysis of variance (ANOVA I). T-test was used in determining the significance of the results comparing the control and the experimental group.  Despite the differences of the effects on the wounds of the rats on the three groups, the wound healing rates were too close to have a significant statistical difference. However, coal tar has managed to properly heal the wounds.

We propose a circuit mechanism with an autocalibration in the impedance measurement circuit based on the auto-balancing bridge method. In the auto-balancing bridge method, an inverting amplifier circuit using an operational amplifier is used. Since the measurement accuracy depends on the feedback resistance of the inverting amplifier circuit, it is necessary to replace the feedback resistor each time as checking the measured value of the resistance of the DUT (device-undertest) so as to match the value. In this work, by employing a current-type D/A converter as a feedback resistor, we design a circuit with calibration of the resistance value and attain highly accurate measurement by simulation.


This article focuses on research from 2022 that critically analyses the ways in which oppressive discourses continue to circulate, and which examines the role of language in protesting and resisting these discourses. It considers studies that remind us of the feminist and queer principles underpinning the field: to question and critique how hegemonic ideologies of gender and sexuality are reproduced and maintained. The review explores two key areas: research that reveals the continuing problem of mainstream transphobia and studies that consider how feminist discourses of resistance operate linguistically. It concludes with a call for more of this research to be applied to real-world contexts in order to create tangible change. In bringing this work together, the review aims to reaffirm the vital and emancipatory role that language, gender and sexuality scholarship has in both documenting and resisting regressive ideology.

In spatial statistics and machine learning, the kernel matrix plays a pivotal role in prediction, classification, and maximum likelihood estimation. A thorough examination reveals that for large sample sizes, the kernel matrix becomes ill-conditioned, provided the sampling locations are fairly evenly distributed. This condition poses significant challenges to numerical algorithms used in prediction and estimation computations and necessitates an approximation to prediction and the Gaussian likelihood. A review of current methodologies for managing large spatial data indicates that some fail to address this ill-conditioning problem. Such ill-conditioning often results in low-rank approximations of the stochastic processes. This paper introduces various optimality criteria and provides solutions for each.


erything which happened, including all the judicial procedures which could be crowded in a limited-time TV program. Omitted are most opening statements and summations, selections of juries, charges to the juries, verdicts and sentences or judgments. In other respects the cases, although very abbreviated, are reasonably complete. Testimony is especially well handled. Nearly all cases are various criminal actions. Each represents a different judicial problem, and comments by the authors make clear the legal principles involved. The programs were televised in a Philadelphia courtroom, and participants were Philadelphia judges, court officers, attorneys and citizens. While undoubtedly attending actual trials is the best education for the prospective court reporter, Court Is in Session is a fair substitute. Courtroom is the legal biography of Samuel S. Leibowitz, who the author said was "the nation's No. 1 criminal lawyer" at the time Leibowitz was elected to a judgeship in New York. The book is largely a review of the important cases in which the defendants were represented by Leibowitz, coupled with the lawyer's philosophy of crime and punishment. Among the notable trials Reynolds covers are those of the Scottsboro boys, Harry Hoffman, Alvin Dooley, Robert Irwin, Louis Greenfield, Vincent CoIl, Laura Parr and Bruno Hauptmann. In his dramatic style, Reynolds makes the cases come alive again. It is a superb reportorial job. Courtroom is good reading for a journalism student, both beoause of the legal procedure covered and because it is the work of one of America's top reporters. A. L.

Mackerel water-soluble proteins' concentrates (SPC), which had been concentrated by the ultrafiltration system, were treated with three kinds of methods. The gel formation properties were also studied on the insolubilized SPC. Over 95% of protein in the SPC was insolubilized by two pH shifting methods: One was to adjust the primary pH of SPC lower than 3 then to 7, the other was to adjust the primary pH of SPC higher than 12 then to 7. The preferable gel was obtained by the pH shifting from 12 to 6. An elastic gel like Kamaboko was obtained from SPC by simple heating when SPC was highly concentrated (over 100mg/1). The alcohols caused insolubilization of SPC and the rate of the insolubilization increased with increasing of the carbon chain length of added alcohols. Insolubilized SPC with 50% ethanol formed a gel by heating, but its gelation property was poor. Fish water-soluble proteins were presumed not to cause gelation; we found, however, that the fish water-soluble proteins could form a gel if they were concentrated by an appropriate method like ultrafiltration.


Standard models of credit frictions do not typically generate substantial amplification and propagation of macroeconomic shocks. I argue that this is directly related to the failure of these models to generate sucient endogenous volatility in asset prices. I introduce learning about the stock market to a model in which firms borrow against the market value of their collateralised assets. A strong positive feedback loop emerges between beliefs, asset prices and profits which reinforces the learning dynamics. Small shocks on either the supply or demand side of the economy then translate into large and persistent aggregate fluctuations.


Learning media needs to be used as a supporter of material delivery to reduce failure in communication and maximize the ongoing process of teaching and learning. Early Childhood Education is in dire need of learning media. With android technology based on android smartphones, learning media becomes more interesting, easier and not boring to learn anywhere and anytime. Learning media in android smartphones are better known as learning applications. The MDLC method is an appropriate method in designing and developing a multimedia application which is a combination of image, sound, video, animation and other media. The MDLC method has six stages as follows: Concept, Design, Material Collecting, Assembly, Testing and Distribution. Recognition of Human Body Members and Movements for Kindergarten Children Based on Android. This application is made using the Android Studio programming language as a medium for making and other supporting software to create images of human body parts. The results of developing educational applications as learning media for early childhood can help in understanding and studying each member of their body.


This study shows that the lower limits for manufacturing add-on costs to convert polysilicon to wafers is in the range of $22 to $26/sq m with the cost about equally divided between the crystal growth and wafering processes. However, the $22 to $26/sq m cost limit should be viewed as an asymptote since it is based on multicharge or continuous growth configurations, solidification rates in excess of 2 Kg/hr, multiblade wafering and a slice plus kerf of .045 cm. It should also be emphasized that the results of this study are based on as-sawn wafers, 100% yields (growth and slicing) and no profit. To the first approximation, the limiting cost factors are crucible material and furnace parts for growth and blade material and slurry for slicing.

Security policies are even harder to write than other system requirements, because they depend on the description of moral judgments rather than of specific behaviours. Interpreting moral judgments in the context of actual software operations is not feasible for computers, but is also too much like programming to be unproblematically delegated to end-users.


This article examines whether and how globally mobile middle-class professional families engage in practices of nationalism through forging connections with a 'home nation' despite continuous relocations for work. Drawing on the concept of boundary objects which are used to facilitate frequent boundary crossings, we identify the promotion of language acquisition and cultural or national rituals and traditions as two central family practices that maintain strong connections to a form of national belonging despite being physically de-territorialised. We coin the term 'mobile nationalism' to make sense of the ways these globally mobile professional parents cultivate a sense of identity, coherence and the necessary resources for future mobility. We argue that these articulations of nationalism continue to be critical as we seek to understand subjecthood formation in the face of the imperatives of globalisation.


In viewing reliability growth prediction models as Markov chains, it is seen that the computation of the reliability after n trials and possible associated repairs, Rn , may be accomplished with any of several different methods. A class of models is considered which accommodates variations in several important factors such as the interdependencies of assignable cause failure modes, inclusion of an inherent failure mode, the repair policy, and the distribution of initial states of the system.

The three-dimensional P and S wave velocity structures and hypocenters of 420 events beneath the western Hazara Arc are obtained simultaneously by inverting travel time data observed at fifteen Tarbela seismic stations. In general, the P and S wave velocity distribution of the top layer (0–6 km depth) correlates well with surface geology. Within this layer we find a low-velocity region beneath the Hazara Thrust Zone (HTZ) corresponding to the underthrusted Murree Formation, and there are high-velocity regions south of the Main Mantle Thrust (MMT) which are associated with the exposed Cambrian, late Paleozoic, and Tertiary granites. A low-velocity zone immediately to the west of the Hazara-Kashmir Syntaxis (HKS) indicates the existence of a Miocene foreland basin which is covered by late stage southeasterly directed thrusts along the Hazara Arc and is consistent with the idea that the HKS is detached from the lower crust. From the Salt Range to the HTZ, the Indian plate dips at a shallow angle, about 2°–3° to the northeast. North of the HTZ the underthrusting Indian plate dips gently to the northeast with an increased slope of 5° to 8° until it reaches the Indus-Kohistan Seismic Zone (IKSZ). Along the NW trending IKSZ the Indian plate bends more steeply to the northeast beneath a seismically active midcrustal wedge directed to the southwest. The larger events in the IKSZ are interpreted as occurring on a major thrust zone that can be followed to a depth of 24 km. The IKSZ appears to consist of an upper seismic zone (from the surface to about 8 km) and a lower seismic zone (12 km to 24 km) separated by an aseismic region about 4 km thick. The lower IKSZ may represent the leading edge of a southwestward directed slab which has not yet ruptured the surface. Hypocenters of relocated earthquakes indicate that the HTZ is about 30 km wide with most of the larger microearthquakes occurring at 12–14 km. Seismicity along the HTZ suggests that the Panjal, and Murree thrusts are active.


We developed a high-resolution fracture productivity calculator to enable fast and accurate evaluation of hydraulic fractures modeled using a fine-scale 2D simulation of material placement. Using an example of channel fracturing treatments, we show how the productivity index, effective fracture conductivity, and skin factor are sensitive to variations in pumping schedule design and pulsing strategy.
 We perform fracturing simulations using an advanced high-resolution multiphysics model that includes coupled 2D hydrodynamics with geomechanics (pseudo-3D, or P3D, model), 2D transport of materials with tracking temperature exposure history, in-situ kinetics, and a hindered settling model, which includes the effect of fibers. For all simulated fracturing treatments, we accurately solve a problem of 3D planar fracture closure on heterogenous spatial distribution of solids, estimate 2D profiles of fracture width and stresses applied to proppants, and, as a result, obtain the complex and heterogenous shape of fracture conductivity with highly conductive cells owing to the presence of channels. Then, we also evaluate reservoir fluid inflows from a reservoir to fracture walls and further along a fracture to limited-size wellbore perforations. Solution of a productivity problem at the finest scale allows us to accurately evaluate key productivity characteristics: productivity index, dimensional and dimensionless effective conductivity, skin factor, and folds of increase, as well as the total production rate at any day and for any pressure drawdown in a well during well production life.
 We develop a workflow to understand how productivity of a fracture depends on variation of the pumping schedule and facilitate taking appropriate decisions about the best job design. The presented workflow gives insight into how new computationally efficient methods can enable fast, convenient, and accurate evaluation of the material placement design for maximum production with cost-saving channel fracturing technology.


In November 1983, Dr. Buddy Brandt, a veterinarian, underwent extensive surgery in Houston with resulting complications requiring multiple blood transfusions. By January 1984, Dr. Brandt developed pneumonia requiring hospitalization. In retrospect, the pneumonia probably was his first Acquired Immunodeficiency Deficiency Syndrome (AIDS)-related illness. Shingles, genital warts, diarrhea, cold sores, mouth ulcers, respiratory infections, and weight loss were chronically experienced by Dr. Brandt. In February, 1986 AIDS-related complex was diagnosed.


Abstract A one-step synthesis of 2t-substituted-1r,3c-bis(2′-hydroxy-5′- substituted-benzyl)-imidazolidines from 1,3-bis(2′-hydroxy-5′-substituted-benzyl)-imidazolidines and aromatic aldehydes is reported. The relative stereochemistry of the five-membered ring was evident from 1H NMR measurements combined with MMX calculations.


The aim of this paper is to present our multidisciplinary project to study parent-child interaction. The goal of the project is to identify, test, and simulate components of child and adult speech and gestures and the consequences they might have on child language acquisition. Since typical parent-child interaction is built upon both interlocutors' intention-reading, responsiveness to joint-attention, and imitation of speech/gestures, we make video recordings along with recordings of speech data to grasp the integration of semantic and pragmatic aspects of language acquisition. The understanding of parent-child interaction benefits further from information on brain activation involved in speech processing. As a first step to achieve the project goals, an electroencephalography/event-related potential (EEG/ERP) study exploring children's early perception of intonation contours involved in human interactions was performed. This paper discusses the characteristics of integration of multimodal social-emotiona...


Metal lithium anodes, with extremely high specific capacity, low density, and lowest potential, are considered to be the most promising anode materials for next-generation high-energy density batteries. However, in the process of repeated plating and stripping of lithium, lithium dendrites are easily grown on the surface of the metal lithium anode, which greatly reduces the capacity of the battery, even causes hidden safety risks and shortens the battery life. This paper reviews the modification methods of lithium anodes based on the growth process of lithium dendrites, and introduces several current modification methods, including electrolyte additives, artificial SEI and new structure of lithium anodes. Finally, the future research direction and development trend of metal lithium anodes are prospected.


The development of an electronic voting system that would replace traditional election procedures is a research topic of great interest for many years. Blockchain technology could provide some guarantees and fulfill strong requirements for electronic voting platforms, such as transparency, immutability, and confidentiality. From time to time research is conducted to address problems in voting systems. Many research works attempt to implement secure and reliable voting systems, which address known security, anonymity, and fraud issues that might threaten such systems. This paper presents a proposal of a secure electronic voting system, the EtherVote, using the Ethereum Blockchain network that focuses deeply on the field of identification of eligible citizens. The proposed system will be entirely based on Blockchain without any central authority servers or databases, thus improving security, privacy, and election cost. Limitations, problems, and solutions are discussed, in order to make the proposed electronic voting system ideal and ready to use for national elections.


In this paper we present a novel system for chemical symbol recognition capable of recognizing and predicting handwritten chemical structures. While the system is aimed primarily at chemists and search engine developers, it is also intended to be used as a learning tool in chemistry education on a student's touch screen computer or in classroom using smart boards. As a student draws on a device screen, the system would provide instantaneous feedback concerning possible chemical structures to complete the drawing, providing a continuously updated table of closely matching candidate symbols, and automatically identifying parts of the molecule that may be combined with other chemical structures. Major building blocks of the suggested system are two Bayesian-based image recognizers: one for collecting input images and one for producing the final output. Between input and output sketch classification is done using state of the art methods. By jointly incorporating feature-based and image-based techniques the system is able to recognize messy artifact-infected sketches and to predict possible terminations. Various performance related experiments proved the system to be considerably faster and more accurate especially when compared to neural-network based techniques.


This paper proposes a single-loop optimization strategy for efficient reliability-based electromagnetic design in the presence of uncertainty. Unlike conventional reliability-based optimization methods, optimization and reliability assessment are totally decoupled from each other during the overall design process. To achieve the desired design feasibility, constraint boundaries of an original design problem are shifted to feasible directions determined by the reliability information of a previous design. After all, the proposed single-loop method for reliability-based optimization performs a serial design of deterministic optimization with shifting constraints and reliability analysis. The proposed method is tested with a mathematical problem and the TEAM Workshop Problem 22, and its numerical accuracy and efficiency is examined by comparison with existing methods.


A sensitive analytical method was developed for determining trace levels of dichlorprop, mecoprop, clofibric acid, and naphthylacetic acid in soil samples. The method applies extraction with acetone and aqueous acetic acid followed by solid-phase extraction as the first cleanup step. After target analytes are derivatized with pentafluorobenzyl bromide, they are determined by capillary gas chromatography (GC)/mass spectrometry with selected-ion monitoring. Further cleanup of sample extract by gel permeation chromatography prevented the GC system from being contaminated with matrix compounds, although in most cases, it was not necessary. Limits of detection and quantitation as low as 0.1 and 1 ppb, respectively, were achieved. Recoveries of all analytes were >90%, with relative standard deviations of <10%.

In this work, the effect of electron beam radiation of linear low-density polyethylene (LLDPE)/ poly (vinyl alcohol) (PVA) blends are presented. The blends were prepared by melt mixing at 150 oC at 60/40 (php/php), of LLDPE and PVA. Gel extraction, infrared spectroscopy diffraction scanning calorimetry, thermogravimetric, tensile properties and scanning electron microcopy had been used to investigate the effect of electron beam radiation on the properties of LLDPE/PVA blends. The exposure of these blends to 200 kGy dose of electron beam radiation increased the gel content, tensile properties (tensile strength and Young's modulus) and thermal stability due to the crosslinking formation, while, the melting temperature of LLDPE and PVA decreased as the PVA content was increased. The crosslink formation between LLDPE and PVA in the irradiated blends was demonstrated by the embedded PVA in LLDPE matrix as observed in optical images.

Cytochrome P-450scc consists of two domains linked with a short loop of the polypeptide chain; under its hydrolysis with trypsin the domains retain their associated state due to rigid noncovalent interactions. The structural characteristics of the individual domains have been investigated. It is established that domain I containing the haem and the adrenodoxin-binding site is the N-terminal, and domain II the C-terminal moiety of the polypeptide chain of cytochrome P-450scc.


The ideological and political course of college self-taught class is the important moral position of college students.We should adopt the following management methods,such as cultivating their learning interest,expanding the study content,and researching the learning target.We need to improve students' problem-solving ability by focusing on hot social issues,have high quality communication with students,and train their self-study initiative and practical operating ability.


The production of hydrogen peroxide (H2O2) drives tumourigenesis in ulcerative colitis (UC). Recently, we showed that H2O2 activates DNA damage checkpoints in human colonic epithelial cells (HCEC) through c‐Jun N‐terminal Kinases (JNK) that induces p21WAF1. Moreover, caspases circumvented the G1/S and intra‐S checkpoints, and cells accumulated in G2/M. The latter observation raised the question of whether repeated H2O2 exposures alter JNK activation, thereby promoting a direct passage of cells from G2/M arrest to driven cell cycle progression. Here, we report that increased proliferation of repeatedly H2O2‐exposed HCEC cells (C‐cell cultures) was associated with (i) increased phospho‐p46 JNK, (ii) decreased total JNK and phospho‐p54 JNK and (iii) p21WAF1 down‐regulation. Altered JNK activation and p21WAF1 down‐regulation were accompanied by defects in maintaining G2/M and mitotic spindle checkpoints through adaptation, as well as by apoptosis resistance following H2O2 exposure. This may cause increased proliferation of C‐cell cultures, a defining initiating feature in the inflammation‐carcinoma pathway in UC. We further suggest that dysregulated JNK activation is attributed to a non‐apoptotic function of caspases, causing checkpoint adaptation in C‐cell cultures. Additionally, loss of cell‐contact inhibition and the overcoming of senescence, hallmarks of cancer, contributed to increased proliferation. Furthermore, there was evidence that p54 JNK inactivation is responsible for loss of cell‐contact inhibition. We present a cellular model of UC and suggest a sinusoidal pattern of proliferation, which is triggered by H2O2‐induced reactive oxygen species generation, involving an interplay between JNK activation/inactivation, p21WAF1, c‐Fos, c‐Jun/phospho‐c‐Jun, ATF2/phospho‐ATF2, β‐catenin/TCF4‐signalling, c‐Myc, CDK6 and Cyclin D2, leading to driven cell cycle progression.


With the beginning of the Late Pannonian, the long-lived Lake Pannon retreated from the Vienna Basin. A fl uvial system, which already developed during the Early Pannonian in the Molasse Basin followed the receding shore. It crossed the basin from the NW towards the SE and established a vast fl oodplain within the fl at basin. The deposits of its southern part are preserved as lignites, pelites and silty sand of the Neufeld Formation, outcropping at the Section Gotzendorf/Sandberg. Mollusc assemblages and the herpetofauna allow the reconstruction of a fl oodplain structured by swift, oligotrophic rivulets accompanying the main channel. The giant salamander Andrias, the olm Mioproteus and the fresh water pearl mussel Margaritifera inhabited these environments. Stagnant lakes and swamp forests developed on the interdistributary areas and were settled by newts, lake frogs, softshell turtles and a manifold planorbid, lymnaeid and rissooid gastropod fauna. The wetlands, indicated by the marly deposits of the section Richardhof, differ in their more distal position along the slopes of the Alps. Their water supply is provided by drainage from the adjacent mountains. The closeness to the mountainous slopes is refl ected in the occurrence of xerophile and/or calciphile gastropods and reptiles. In contrast, indices of fast-fl owing lentic environments, such as typifi ed by the Gotzendorf fauna, are nearly absent. The chosen time-slice comprises only faunas of the Mytilopsis neumayri/Mytilopsis zahalkai Zone and the upper part of the mammal zone MN 9, respectively. The slight stratigraphic difference of the faunas as indicted by the evolutionary levels of the smaller mammals probably refl ects a diachronous development of wetlands in the Vienna Basin. Along the western basin margin, wetlands might have developed earlier than in the more central parts of the Vienna Basin.

The quantity of bromide which can safely be ingested by different persons varies enormously. The variability seems to depend not only on the differences with which various persons retain bromide but on the different concentrations of bromide which cause clinical symptoms of bromidism in different persons. For two reasons, therefore, it is necessary for the clinician to guard against bromide intoxication even in instances in which the bromine forms a relatively small portion of the bromide molecule prescribed. Since the advent of prostigmine bromide as a means of administering prostigmine orally in the treatment of myasthenia gravis, patients with this disease have had a means of steadier relief from symptoms in addition to obviating the necessity for numerous hypodermic injections of prostigmine methylsulfate. The case here reported, however, shows a possible danger through bromidism in the self administration of prostigmine bromide—a danger which one would hardly anticipate and one of


Forests Resources are vital to the economic life of the Finland. 85.5% of the total land area is under forestry operation. The total growing stock is estimated to be 1410 million m 3 . The unbarked volume of the growing stock by dominant tree species is 606 million m 3 of pine, 530 million m 3 of spruce and 274 million m 3 of deciduous species.According to Ownership 63% of the forest belongs to the farmers, 28% is publicly owned and 9% is owned by Corporations, local authorities,etc. In the country there is awareness for protection, improvement and increasing the productivity of the woodlands to sustain the expansion of wood using industries.Finland is a country living decisively on forests, probably more so than any other country in the world. The area covered by forests in Finland is 26.2 million hectares (as per results of the IV inventory) giving an average of 50 hectares per capita. The total growing stock is estimated to be 1410 million cubic meters, giving an average of 54 m 3 per hectare.The quality of the forests is better in the southern part of the country giving an average volume of 100 m 3 per hectare. The annual growth is calculated to be more than 46 million m 3 (excluding bark) on an average1.7 m 3 per hectare, which is likely to be raised to the tune of 58 million m 3 in near future.


In [1] we considered free boundary problems arising in the study of the optimal stopping problem for a Markov process, and proved uniqueness theorems for solutions of such problems. Here we shall prove the corresponding theorems for the existence of a solution, using methods similar to those proposed in [2], [3]. The free boundary problem considered here was formulated in [1], where an integral identity defining a weak solution of the problem was given. We note that the free boundary problem (l)-(4) of [1] can have infinitely many solutions if we enlarge the uniqueness classes defined there. Let us give an example. Let


In this paper we introduce a concept of skewness and suggest its measure among a class of unimodal distributions. The measure is built on the lack of symmetry of the density function around the the mode of the distribution. It is shown to satisfy all standard properties expected from a measure of skewness, including location and scale invariance. The extreme values of the measure are characterized. Although the measure is defined for a relatively narrow class of distributions, its utility is established by showing that it is applicable for most popularly used continuous distribution families. The introduced measure is compared with the other established measures like Pearson's skewness and standardized third moment and it is shown to be more strict. Two alternative ways of partial ordering among the distributions based on this skewness are also described. The utility of the proposed measure is examined in other cases including discrete distributions.


Waste management has taken the front purview in recent years due to the evident and attendant effects of indiscriminate disposal of wastes to the environment. This led to the preliminary investigations for the proposed siting of a landfill facility in Lafia and environs of Nasarawa State in Central Nigeria, with the aim of providing valuable information on the suitability for location for the disposal of Municipal Solid Waste (MSW). The combined use of geo-resistivity, geological and hydrogeological investigations were carried out for the study. Ten Vertical Electrical Soundings (VES) of the Schlumberger array was used to investigate the properties of the subsurface lithologies to determine their properties especially, clay, for siting a landfill. Clay, an attenuating material, is significant for siting a landfill facility because it tends to isolate potentially toxic wastes from the environment by slowing down the movement of leachates into groundwater and the environmental. Quantitative interpretation of data of the VES survey using the IPI2win computer software revealed the presence of four to five geologic layers comprising of sandy top soil (247 – 1964Ωm), silty sand (98 – 3488Ωm), clayey-shally/sand (68 – 3922Ωm), saturated clayey sand (31 – 3226Ωm) and loose sand (478Ωm). Clay was found to be abundant in the area and found at depths ranging from 30m to infinity. Geologically, structures like lineaments abound and were analysed; they show a dominant trend in the NW – SE direction from the Rosette Diagram. Lineaments are useful for studies because they are possible conduits where decomposed wastes in liquid form, such as leachates, get transported to pollute groundwater. Hydrogeological studies surveyed Static Water Levels (SWL) measurement from 51 hand dug wells in the study area. The SWL ranges between 5.8m and 37.1m. The data from the SWL was used to construct the absolute water level map in a 3D form to show the flow direction of the groundwater. The study revealed the presence of impermeable clays at VES 1, 2, 3, 9 and 10. This is significant for selection for landfill due to its pollution-prevention properties of groundwater pollution. The investigations carried out in this study show that Shabu, a town located about 8km from Lafia, is likely suitable for siting a landfill facility; because of the abundance of clay at a shallow depth of 30m and with limited preponderance of lineaments.


Aims: People with COPD and persons with HIV have been recognized as medically and socially vulnerable populations during the COVID-19 pandemic Data on the impact of the pandemic and its response on the psychosocial wellbeing and medical care of persons living with HIV and COPD is lacking We evaluated the mental health and health-care utilization consequences during the pandemic in this population Methods: We surveyed Pittsburgh HIV Lung Cohort participants from May through July 2020 Demographic and clinical data included age, sex, race and smoking history Anxiety, depression and insomnia during the pandemic were evaluated using the General Anxiety Disorder-7 scale, Patient Health Questionnaire- 9 and Insomnia Severity Index The survey assessed for COVID-19 symptoms, health-care access/ utilization and risk/protective behaviours Continuous variables were compared between participants with and without COPD using t-test and Mann-Whitney test as appropriate and categorical variables were compared using Fisher's exact test Multiple and ordinal logistic regression was used to evaluate the association of COPD and any interaction effect by HIV status with anxiety, depression, insomnia, general health status, health-care utilization and risk/protective behaviours All statistical tests were two-sided Results: 136 individuals were included: age 57 9 ±9 5 years;76 5% male;60 3% Caucasian and 39% Black;47% current or former smokers Forty-two (30 9%) respondents screened positive for anxiety disorders, 35 (25 7%) had major depressive disorder and 7 (5 1%) reported insomnia Median scores and proportions across categories by severity of symptoms did not differ by COPD status Of 22 participants with new or worsening symptoms that could be related to COVID-19, only 10 sought medical care Participants with COPD reported similar levels of concern about seeking care due to potential COVID-19 exposures (50 0% versus 42 9%;P=0 64), interruptions in medical care (30 4% versus 27 4%;P=0 801) and a trend to less delay in diagnostic testing as those without COPD (8 7% versus 20 4%;P=0 247) Individuals with COPD were more likely to have sought emergent or urgent care since March (30 4% versus 8 0%;P=0 007) Although all respondents reported practicing social-distancing and masking, the majority (119;87 5%) had in fact continued interacting with people outside the household and 38 (27 9%) joined large gatherings Those with COPD reported similar risk behaviour as those without There was no interaction effect by HIV status See Table 1 Conclusions: Anxiety, depression and concern of COVID-19 exposure were prevalent among persons with and without COPD or HIV Many respondents experienced interruptions in medical care and diagnostic testing and concern about health-care-associated COVID-19 exposure, but this was not more severe inthose with COPD or HIV Despite likely higher risk of poor outcome in those with COPD, individuals with COPD were not more likely to curtail social interactions than those without COPD HIV status also did not seem to modify the impact of COVID-19 on behaviours in this group


In view of the characteristics of energy consumption in wireless sensor network nodes in the process of mechanical vibration detection, compression sensing technology (CS) was introduced. The system completed the sparse representation of the signal and the design of the orthogonal measurement matrix in the DSP of the terminal nodes. After wireless transmission of the measurement data to the coordinator node, with the help of CCSLink platform, it realized the reconstruction of the signal in the MATLAB environment. It was found that the sparse signal after DCT transformation had better sparsity, and the signal reconstructed by OMP algorithm had higher reconstruction accuracy. The introduction of compressed sensing technology not only reduced the data transmission capacity of wireless nodes, reduced the power consumption of data transmission, and also extended the life of nodes, which proved the feasibility of compressed sensing technology in the field of mechanical vibration monitoring.


The ultimate goal of any world-class swimmer is to break a record, and technology enables that accomplishment. Using 40 years of data at the individual, national and international level, we identify the quantitative impact that innovation has had on the number of record breaks. We find small but statistically significant impacts on both the number of breaks and the interval between breaks.


In metro cities, the monitoring, organizing and controlling road traffic has become a challenge to make human life easier. A vehicular Ad-Hoc Network (VANET) is a promising research area to reduce the day to day hurdles in traffic flows. It is used to collect and provide the vehicular information such as speed of a vehicle, operational conditions, traffic density, traffic flow and average waiting time etc. to the Traffic Light Controller (TLC) at a four-way intersection. Therefore, safe, simple and cost-effective solutions are required to increase transportation efficiency using VANET. Research on Artificial Intelligence technique e.g. Neuro-fuzzy controller, reinforce learning, evolutionary algorithm and static embedded controller is ongoing to adjust to the traffic-related problems but difficult to implement. We present a Traffic Light Controller (TLC) design to monitor Green Light-time Estimation (GLE) and delay for efficient traffic flow. This Adaptive TLC based on Fuzzy Inference System (FIS) observes current traffic condition around the intersection and controls the traffic signals to obtain efficient traffic flow. This paper compares and presents two approaches of TLC-first approach considers the traffic density and traffic flow rate for estimating green light time. The second approach observes the green light time on the basis of traffic flow rate, queue size, and vehicular communication data before controlling traffic light.


A very compact architecture for the lightweight 256-bit hash function Lesamnta-LW is presented in this paper. The proposed architecture has an 8-bit datapath and requires very few hardware resources and, therefore, can be a prime candidate for resource constrained devices. The proposed architecture was designed and implemented on the BASYS3 board (Artix 7 XC7A35T) using the VERILOG hardware description language. The implementation utilizes only 434 FPGA LUTs, 474 FFs and reaches a throughput equal to 50 Mbps at 161 MHz clock frequency.


Background: The treatment of burns has always been a challenge in terms of their seriousness, as the multiple complications that usually occur in proportion to the time needed to cure the lesion. The therapeutic laser is a monochromatic and coherent light that has been used to induce the healing of wounds indolent. Objectives: The study aims to describe the effects, the mechanism of action and application parameters of therapeutic laser on the healing of burns. Methods: A bibliographic survey was carried out through books and publications indexed journals (MEDLINE, LILACS, SciELO, CAPES) that address the issue in question. Results: This review shows that the laser therapy accelerates the proliferation of reparative cells and increases the organization of collagen, but there is a lack of studies using burns as an experimental model, lack of standardized criteria and application information on the depth of the lesion. Conclusion: Laser treatment can be a valuable resource in the treatment of burns by its ability to induce rapid healing and organized.


I am currently working on a postgraduate thesis exploring the role, function and legal liability of those nurses working in a consultant nurse capacity. This is a substantial study which will seek to define this group of nurses and their professional and legal accountability.


In the international comparison significant differences regarding the future demand come into view. In Romania and Portugal, where the ICT qualification is dominated by universities degrees, the companies correspondingly see the biggest demand on qualification level 5M (masters' degree). For Portugal this is the only group where companies see a significantly higher demand in the near future. For the Czech Republic and Germany only one fifth of the companies say there will be a higher demand on university based level 5M and in the Netherlands, it is even less, with only 10% of the companies. In these three countries - and particularly in the Czech Republic - almost half of the companies foresee a higher demand on level 5B.


This paper focuses on the role of the production scheduler in developing and using a computer simulation based scheduling system. As the scheduling system end user, the production scheduler is responsible for developing schedules which support the business goals of the manufacturing facility. To do so, he must balance many conflicting objectives relating to work-in-process inventory levels, resource utilizations, and customer service. During any single scheduling period, the desired balance may vary with time or across production resources. Simulation based scheduling does not provide an optimum solution, but provides visibility into the effects of decisions. The production scheduler uses this information to perform analyses and to identify opportunities to improve the plan. His participation during system development ensures that the model and reports fully support these activities. While the schedule generation and revision process can be automated, the final analysis of the value of the resulting schedule requires human involvement. A FACTOR scheduling software application is reviewed to illustrate the role of the user in this dynamic environment.


Maximization of mutual information between the model's input and output is formally related to"decisiveness"and"fairness"of the softmax predictions, motivating such unsupervised entropy-based losses for discriminative models. Recent self-labeling methods based on such losses represent the state of the art in deep clustering. First, we discuss a number of general properties of such entropy clustering methods, including their relation to K-means and unsupervised SVM-based techniques. Disproving some earlier published claims, we point out fundamental differences with K-means. On the other hand, we show similarity with SVM-based clustering allowing us to link explicit margin maximization to entropy clustering. Finally, we observe that the common form of cross-entropy is not robust to pseudo-label errors. Our new loss addresses the problem and leads to a new EM algorithm improving the state of the art on many standard benchmarks.


The proliferation of Web-based learning objects makes finding and evaluating resources a considerable hurdle for learners to overcome. While established learning analytics methods provide feedback that can aid learner evaluation of learning resources, the adequacy and reliability of these methods is questioned. Because engagement with online learning is different from other Web activity, it is important to establish pedagogically relevant measures that can aid the development of distinct, automated analysis systems. Content analysis is often used to examine online discussion in educational settings, but these instruments are rarely compared with each other which leads to uncertainty regarding their validity and reliability. In this study, participation in Massive Open Online Course (MOOC) comment forums was evaluated using four different analytical approaches: the Digital Artefacts for Learning Engagement (DiAL-e) framework, Bloom's Taxonomy, Structure of Observed Learning Outcomes (SOLO) and Community of Inquiry (CoI). Results from this study indicate that different approaches to measuring cognitive activity are closely correlated and are distinct from typical interaction measures. This suggests that computational approaches to pedagogical analysis may provide useful insights into learning processes.

Abstract Objective: To describe the therapeutic itinerary of people with tuberculosis in face of their health needs. Method: Descriptive, qualitative study. Semi-structured interviews were carried out with ten patients. Hermeneutic-dialectic method of analysis and concept of therapeutic itinerary as driver of the analysis. Results: Most had classic symptoms at the beginning, however there was a case with coughing for more than one year. Entrance door, access to diagnosis and treatment were predominant in Primary Care, through smear microscopy and X-ray; patients had to pay for exams. Decentralization of treatment for other services when necessary or by link with the professional. The patient followed the decisions of the professionals and the support of relatives; prejudice regarding the disease was noted. Conclusions and implications for practice: Fragility in disease management, importance of bonding and family. It should be considered the impact of the disease and the need to support patients to ensure continuity of care.


Children undergoing stem cell transplant (SCT) experience high levels of somatic distress and mood disturbance. This trial evaluated the efficacy of complementary therapies (massage, humor therapy, relaxation/imagery) for reducing distress associated with pediatric SCT.


In the design process of inductive power transfer systems the shape of the inductive component is essential for the operation point, the losses and thus the efficiency. Based on a new placement approach, the amount and position of the windings within the inductive component is defined by a parameter set. With the help of a genetic algorithm these parameters are modified and iteratively optimized with regard to the core and winding losses, calculated by a coupling workflow combining FEM and circuit simulations. The results demonstrate a large variety of geometric winding designs and yield a pareto optimum for the balance of the both dominating loss shares in inductive components.


A Directional Nearest-Neighbor graph is defined on a finite set of points in the plane by drawing an arc from each point X to its nearest neighbor in each of r divisions of the plane relative to X. We prove that Directional Nearest-Neighbor graphs having $r = 4$ are strongly connected.


This paper proposes a comparative assessment between PD and fuzzy controls applied to an autonomous aerial vehicle inspired by owls to accomplish a silent and stable flight. Firstly, the owls' flight is analysed to determine different components of a particular trirotor drone. Afterward a detailed study, the mathematical model is developed using kinematics and aerodynamics laws. Next, the theoretical model is employed to synthesize a control strategy based on PD and then on fuzzy concepts to stabilize the drone in a hovering situation with the adequate altitude and attitude. The fuzzy controller is compared to the PD to display its performances in terms of precision and trajectory tracking.


The approval of the BESSY II project marked the start of the construction of the first third generation synchrotron light source in Germany. BESSY II, designed for low emittance (/spl epsiv/=6/spl middot/10/sup -9/ radm) and the incorporation of a large number of insertion devices (IDs) is expected to deliver VUV to XUV radiation with a brilliance in excess of 10/sup 18/photons/(sec/spl middot/mm/sup 2spl middot/mrad/sup 2spl middot/0.1% bandwidth), the photon energies ranging from 10 to 2000 eV from undulators and wigglers. Photon spectra with a critical energy of 11.5 keV will be generated in the 6 T field of a superconducting wavelength shifter (WLS) which is planned to be installed in one of the 14 straight sections available for insertion devices. The decision to build BESSY II at a new site at Berlin Adlershof gave the challenge for a complete redesign of the storage ring without the severe boundaries compared to earlier proposals, with respect to requirements and practicabilities of constructing an accelerator complex mid in the center of West-Berlin.<<ETX>>


Satellite communication has recently been included as one of the enabling technologies for 5G backhauling, in particular for the delivery of bandwidth-demanding enhanced mobile broadband (eMBB) application data in 5G. In this paper we introduce a 5G-oriented network architecture empowered by satellite communications for supporting emerging mobile video delivery, which is investigated in the EU 5GPPP Phase 2 SAT5G Project. Two complementary use cases are introduced, including (1) the use of satellite links to support offline multicasting and caching of popular video content at 5G mobile edge, and (2) real-time prefetching of DASH (Dynamic Adaptive Streaming over HTTP) video segments by 5G mobile edge through satellite links. In both cases, the objective is to localize content objects close to consumers in order to achieve assured Quality of Experiences (QoE) in 5G content applications. In the latter case, in order to circumvent the large end-to-end propagation delay of satellite links, testbed based experiments have been carried out to identify specific prefetching policies to be enforced by the Multiaccess computing server (MEC) for minimizing user perceived disruption during content consumption sessions.


Sarcoidosis of the skull is quite rare, only 3 cases confirmed by bone biopsy being reported in the literature (1–3). The case to be presented here is the fourth to be confirmed by histopathologic study and, in addition, showing complete regression without treatment. Osseous lesions occur in a small percentage of patients with sarcoidosis and are usually in the hands and feet. Case Report A 51-year-old white housewife was seen at the Marshfield Clinic (Marshfield, Wisc.) on Oct. 31, 1958, because of intermittent swelling of the neck for three years, along with occasional pains over the right side of her head and face. She had also noticed a "spot" on the left labium majus, with intermittent swelling and ulceration for two years. Physical examination revealed an almond-sized node in the right anterior cervical chain and a small right submandibular node, with no other adenopathy. The heart and lungs were normal, and the liver and spleen were not palpable. An annular lesion, 1 cm. in diameter, with an ulcera...


Samburu body adornment identifies a woman's beauty, husband and social rank in the community through colour, pattern and mass. In the last sixty years, as a result of Kenya's entrance into the global economy, Samburu women have turned the indigenous body adornment into commodities creating products for western tourists. The ability of Samburu women to create employment has articulated their empowerment and in turn challenged the patriarchal gerontocracy norms dominant in Samburu culture. The study was informed by cultural theory. Culture includes knowledge, believes, art, law, morals, customs and other skills acquired by man as a member of society. Cultural history focuses on the changes and practices in human agency. Culture is transmitted across generations through the memory which is a faculty of the individual mind. Data was collected by use of oral interviews, archival search, non-participant observation as well as thorough the examination of secondary sources from various libraries. The data was analyzed using Ex Post Facto design.

Key Words: Samburu, Women, Culture, Gender, Globalisation


Cultures of human diploid fibroblasts (HDFs) exhibiting density dependent inhibition of replication (DDIR) resumed their progression through the cell cycle following medium replacement and, after a lag period of two hours, showed a dramatic increase in the incidence of isonucleolinar 4 cells and in the levels of uptake of 3H‐uridine into the nucleoli. Between five and ten hours after refeeding these nucleolar changes were maximal, leveling off at the highest values, in periods corresponding to late G1 and early S. Concomitantly, a parallel increase in the number of nucleolini per cell occurred. As cells progressed through S and G2 phases the nucleolini decreased in number and reverted to the aniso‐nucleolinar type. The intensity of nucleolar labeling by 3H‐uridine and its correlate, the frequency of cells with labeled nucleoli, also decreased during these cell cycle stages. Both pre‐ and postreplicative periods of mitotic quiescence were characterized by high levels of anisonucleolinosis (60–80% of the cells) and by very low levels of nucleolar 3H‐uridine incorporation.


Starting from the in situ generated free carbenes dipyrido[1,2-c;2′,1′-e]imidazolin-6-ylidene (dipiy) and 2,10-di-tert-butyldipyrido[1,2-c;2′,1′-e]imidazolin-6-ylidene (dipiytBu), the synthesis of the new carbene complexes [RhCl(COD)(dipiy)] and [RhCl(COD)(dipiytBu)] can be achieved. Upon chloride abstraction and coordination of phosphine, a very active precursor for the catalytic hydrosilylation of ketones is formed. The reaction was also followed by NMR spectroscopy. In addition the respective CuI(dipiytBu) complex was synthesized and fully characterized. X-ray structure analysis reveals this compound to be a trimer [CuI(dipiytBu)]3 with two Cu−Cu bonds in the solid state. However, unlike the imidazolinylidene analogues, this complex and in situ prepared CuX(dipiy) complexes (X = I, Cl) were found to be inactive in the hydrosilylation of ketones.


The RD‐X19 is an investigational, handheld medical device precisely engineered to emit blue light through the oral cavity to target the oropharynx and surrounding tissues. At doses shown to be noncytotoxic in an in vitro three‐dimensional human epithelial tissue model, the monochromatic visible light delivered by RD‐X19 results in light‐initiated expression of immune stimulating cytokines IL‐1α and IL‐1β, with corresponding inhibition of severe acute respiratory syndrome‐coronavirus 2 (SARS‐CoV‐2) replication. A single exposure of 425 nm blue light at 60 J/cm2 led to greater than 99% reductions against all SARS‐CoV‐2 strains tested in vitro, including the more transmissible (Alpha) and immune evasive (Beta) variants. These preclinical findings along with other studies led to a randomized, double‐blind, sham‐controlled early feasibility study using the investigational device as a treatment for outpatients with mild to moderate coronavirus disease 2019 (COVID‐19). The study enrolled 31 subjects with a positive SARS‐CoV‐2 antigen test and at least two moderate COVID‐19 signs and symptoms at baseline. Subjects were randomized 2:1 (RD‐X19: sham) and treated twice daily for 4 days. Efficacy outcome measures included assessments of SARS‐CoV‐2 saliva viral load and clinical assessments of COVID‐19. There were no local application site reactions and no device‐related adverse events. At the end of the study (day 8), the mean change in log10 viral load was −3.29 for RD‐X19 and −1.81 for sham, demonstrating a treatment benefit of −1.48 logs (95% confidence internal, −2.88 to −0.071, nominal p = 0.040). Among the clinical outcome measures, differences between RD‐X19 and sham were also observed, with a 57‐h reduction of median time to sustained resolution of COVID‐19 signs and symptoms (log rank test, nominal p = 0.044).

ABSTRACT This research compares the capabilities of various Sentinel-2-derived spectral vegetation indices (SVIs) in particular red-edge SVIs to detect and classify spruce budworm (Choristoneura fumiferana) (SBW) defoliation using Support Vector Machine (SVM) and Random Forest (RF) models. The results showed the superiority of RF in model building for defoliation detection and classification into three classes (nil, light, and moderate) with overall errors of 17% and 32%, respectively. The most important variables for the best model were Enhanced Vegetation Index 7 (EVI7), Modified Chlorophyll Absorption in Reflectance Index (MCARI), Inverted Red-Edge Chlorophyll Index (IRECI), Normalized Difference Infrared Index 11 (NDII11) and Modified Simple Ratio (MSR). Red-edge SVIs were more effective variables for light defoliation detection compared to traditional SVIs such as Normalized Difference Vegetation Index (NDVI) and EVI8. These findings can help improve current remote sensing-based SBW defoliation detection and monitoring.


The alien Plag;obothrys seouleri (Hook. & Am.) I. M. Johnst. , White forget-me-not, was first observed in Britain in 1974, and has now been recorded in eight vice-counties. Several populations have been short-lived, but in Hampshire and North Aberdeenshire (v. cc I I and 93) persistent large colonies exist in open habitats that regularly flood . Details are given about all British records , a common feature being occurrence in sown grass, which implies that P. seoL/ler; is a seed impurity. Morphological variation between colonies is assessed . The North Aberdeenshire colony occupies a large dune slack at St. Fergus across which gas pipelines have been laid , and it is believed that restoration work led to P. scouleri being introduced ; the plant is now abundant over the whole extent of the c. 5 ha "winter loch". The sequence of events permitting spread at St. Fergus, and the plant communities in which P. scouleri occurs there, are described.


1. An investigation to compare winter and spring defoliation of S.147 oats, and incorporating an application of nitrogen, was carried out during the seasons 1950/1, 1951/2 and 1952/3. 2. Forage available in the spring was considerably greater than that available in the winter, but it had a lower crude-protein content. 3. Compared with the undefoliated oats, both spring and winter defoliation reduced the number of productive tillers by significant amounts, but nitrogen had no effect on tiller numbers under defoliated and undefoliated conditions. 4. Spring and winter defoliation caused significant reductions in grain yields; with winter defoliation the decline in yields was substantial. On the undefoliated and spring-defoliated oats nitrogen increased yields by significant amounts. 5. Spring and winter defoliation reduced straw yields, but nitrogen on both treatments and on the undefoliated oats gave significant yield increases.


We demonstrate the feasibility of observing and inducing magnetization switching using the distance dependence of the magnetic exchange interaction. The experiments were performed employing an atomic force microscopy setup on the antiferromagnetic iron monolayer on the (001) surface of tungsten with magnetic tips that behaved like independent superparamagnetic clusters with uniaxial anisotropy. Applying the Neel-Brown law, we were able to determine energy barriers from lifetimes measured at different distances with and without external magnetic field. Our findings suggest that the distance dependence of the magnetic exchange interaction can be utilized to monitor and control magnetization dynamics on the atomic level.


This paper is an attempt to explore fundamental rights which is incorporated in our constitution on the basis of international human rights law. Bangladesh is a deltaic country situated in the Bay of Bengal having over 160 million of people. In spite of ratification of many international human rights instruments, every year many peoples are deprived to exercise fundamental rights because of political unrest. The Fundamental Rights of Bangladesh Constitution themselves have no fixed content, most of them are empty vessels into which is generation must pour its content in the light of experience. The study intends to examine violation of fundamental rights in the light of present situation. Furthermore, this paper attempts to examine the general criticisms of the enforcement of fundamental rights and desirability of judicial activism in the fulfillment of such right. The main purpose of this paper is to ensure fundamental rights by imposing the international human rights instruments by the political parties as well as our domestic court.


An important goal of corporate knowledge management is to stimulate organizational learning by enabling the effective collection, dissemination, and utilization ofavailable knowledge in an organization. Knowledge management as a whole goes well beyond single technical solutions. We clarify the role of information systems in knowledge management and demonstrate a model-based approach for a corporate memory where a domain model guides the continuous evolution and the retrieval of information. The necessary contributions from various fields are illustrated by means of a concrete corporate memory for maintenance support in a German black coal mine: the particularities of the organizational structure, the experts involved, and the work environment together lead to the realization of an information system which supports the human workers in their maintenance task. The system described here was put into use in September 1997 and first success stories can be told.


In this paper, robust adaptive stabilization is discussed for time‐varying discrete time systems with disturbances and unmodelled dynamics. Both bounded and unbounded stochastic disturbances are considered. It is assumed that the parameters of the nominal model belong to a bounded convex set and that the 'frozen time' nominal model is stabilizable for all possible parameter values. Requiring neither external excitation nor stable invertibility of the nominal model, an adaptive regulator is constructed on the basis of the solution to a finite time Riccati equation and a projected gradient estimator. It is shown that the closed‐loop system is stable if both the time average of the parameter variations and the model error are sufficiently small.


The coatings of MoSi2/Al2O3 composites with MoSi2 particles as absorber and Al2O3 as matrix were prepared by plasma spraying method.The content of MoSi2 and its effects on the mechanical and the dielectric properties of the composites were investigated.It is found that the MoSi2 particles are distributed uniformly in matrix.The bending resistance,fracture toughness and impact strength all increase while the dielectric constant decrease with the increase of the content of MoSi2.The results of dielectric constant testing in the range of 8.2~12.4GHz indicate that the dielectric constant real par of all samples decrease with the increase of frequency,showing obvious frequency dispersion effect.


Acute intermittent porphyria is an autosomal dominant inborn error characterized by decreased activity of porphobilinogen deaminase leading to increased levels of haem precursors, namely aminolevulinic acid and porphobilinogen. Posterior reversible encephalopathy syndrome is a clinical radiographic syndrome of heterogeneous etiologies characterized by headache, seizures, altered consciousness, and visual disorder associated with potentially reversible neuroradiological abnormalities predominantly in the parieto-occipital lobes. There are few previous reports of acute intermittent porphyria associated with posterior reversible encephalopathy syndrome, which are thought to result from peaks in hypertension.


Abstract Aorta catheterisation can serve both diagnostic and therapeutic purposes in patients with aortic coarctation, especially when non-invasive evaluation cannot define severity of the abnormality. We report a case of bilateral brachial plexus injury due to standard positioning of the patient's arms during non-complicated aorta catheterisation and aortic stent implantation under general anaesthesia. In discussion, we consider our patient's predisposing factors, the understanding of which may be helpful in avoiding this complication in the future.


A crown-type probe seal 30 for a female hydraulic coupling member 10 has one or more circumferential, spring-energized seals 40. One particular preferred seal comprises a closely-wound helical spring 40 which imparts an inwardly-directed radial force to the crown seal 30. In certain embodiments, the helical spring 40 is substantially encased in a polymer jacket 52. In yet other embodiments, a liner 42 is interposed between the outer surface of the helical spring 40' and the polymer jacket 52. An optional, axial extension on at least one end of the crown seal provides a bore liner for a female hydraulic coupling member in which the crown seal is installed, figs 3A & 3B.

The availability of large localized datasets from popular social-networking sites such as Foursquare and Twitter has enabled the expansion of the field of human mobility analysis. Extracting location information from user trajectories helps to increase the understanding of human mobility and is important for improving public health, city planning, as well as crime prevention. In this work, we introduce a framework to automatically discover and classify locations based solely from geo-temporal data and without relying on contextual data, such as user explicit check-ins. We collected a dataset of 3 millions geo-tagged tweets of the New York City area to test our framework. By using a combination of clustering algorithms to accurately pinpoint location position (from a cloud of points representing tweets), and the popular time/days histograms as features to train the classifier, we were able to reach up to 53% average accuracy for the location type classification.
