ABSTRACT Objective: to investigate the knowledge and attitude of school adolescents regarding sexual violence. Method: a qualitative study with data gathering, based on Maurice Merleau-Ponty's Phenomenology of Perception, conducted in April 2018 with 12 adolescents from a state school in Recife, using the focus group technique. For data systematization, thematic content analysis was used in the following steps: pre-analysis, material exploration, treatment of results and interpretation. Results: three thematic categories were established: adolescents' perceptions of sexual violence; reflective construction of adolescents on the factors of exposure to sexual violence; and facilitating aspects for the prevention of adolescent sexual violence. Conclusion: the perception of adolescents regarding sexual violence is influenced by cultural, structural, social, economic, psychological and biological aspects, which should be considered in the planning of actions aimed at preventing sexual violence for this public.


In this paper, according to the analysis of the ablative mechanism of thermal protective materials under elevated temperature, the ablation-phase transformation properties and the thermomechanical behavior of the component materials are investigated by Eshelby equivalent inclusion method. Through the hypothesis of the statistical uniform distribution of the phases consisting of solid products of thermodestruction at high temperatures and pores in the materials, the interaction among different phases by complicated internal physico-chemical processes in a matrix and fibers is considered. The exact relationship between the micro-structure and the macro-behavior for composites reinforced with unidirectional continuous fibres is expressed, and the numerical solution is also given. With the help of the model, the following high-temperature phenomena have been described: degradation of elastic moduli of the composite in the reinforcing direction in heating, and dependence of heat properties of the composite not only on temperature but also on duration of heating. Comparison of the theoretical and experimental results for typical ablative materials showed that the model allows one to forecast the thermomechanical characteristics of the composites according to the properties of their matrices and fibers with sufficient accuracy. It will be helpful for the analysis of the composite materials high-temperate structure.


Purpose: The study was conducted to identify and evaluate disaster risks and mental health outcomes caused by extreme climate events.
Methodology: Quantitative data was obtained from existing climate and mental health (1984-2019) records, while qualitative data was obtained from literature review of case studies and content analysis, Focus Group Discussion and household survey in four major zones for two consecutive years. ArcGIS software method explored various properties of the climate systems to infer the distribution of climate parameters, select extremes value and calculate linear trend of time series. The quantitative data was analyzed using statistical tools in Excel, IBM SPSS version 20 while climate data analysis was done using R software (version 3.21).
Results: The exceedance threshold of 𝜇 = 340 𝑚𝑚 was chosen. On the other hand, mean exceedance threshold of 𝜇 = 36.50𝐶 and 𝜇 = 11.380𝐶 for minimum and maximum temperatures respectively. The rainfall band was very high or very low, deemed to create disaster risks. The results revealed that the most common disaster risks include: drought and heatwaves, strong sand storms, flash floods and floods. The duration of time, frequency and unpredictable weather variability events were above critical threshold, hence categorized as high risk, rated 1, hence fatal.
Unique Contribution to Theory and Practice: The study provides historical empirical data on hazard mapping and mental health outcomes to enable policy and programmes formulation by state and nonstate actors. The study recommends development of robust environmental health procedures to diagnose mental disorders, mapping of disasters; mental disorder epidemiology and make it user friendly to advice policy, scale up solutions and accelerate evidence informed advocacy on adaptation and resilience mental health programme strategies


Intravenous recombinant tissue plasminogen activator (rtPA) is thought to benefit patients with acute ischemic stroke by producing early reperfusion.1 Transcranial Doppler (TCD) is a noninvasive method that can monitor the recanalization process in real time when occlusion occurs in the proximal intracranial vessels.

We present our findings during rtPA infusion in a 56-year-old man with acute ischemic stroke to illustrate the time course of changes that occur in a middle cerebral artery (MCA) stem occlusion treated by intravenous thrombolysis. We used a 2-MHz portable unit (Multigon 500 mol/L) with a pulse-wave transducer mounted on a head frame (Marc 500, Spencer Technologies) …


The increasing number of communication transmitters makes passive radar an attractive and simple alternative to active radar systems. GSM base stations as illuminators for passive radar enjoy the advantage of digital waveform, frequency diversity and global availability. The problems with these transmitters are the low transmit power and the more or less directive transmit patterns. These limit the achievable range. This paper studies how a useful system can be designed by fusion of bistatic systems using multiple transmitters.


At the past optical security conferences attention was focused on diffractive structures, e.g. holograms, embossed gratings and thin—film devices, as security elements on valuable documents. The main reasons for this emphasis are, that the iridescent effect of such diffractive optically variable devices (OVD's) can be easily observed by the naked eye and that their fraud-resistance is considered excellent. No attention has been paid to non—diffractive optically variable phenomena like reversible photosensitivity, e.g. luminescence and photochroism. These may be employed in non-diffractive OVD's which may be readily authenticated and may provide excellent fraud-resistance as well. In order to survey the enormous variety of document security features the library SECURIDAT was compiled from a number of public domain databases. This paper discusses a few security applications of reversible photosensitivity that resulted from a search in SECURIDAT, viz. dual fluorescence with longwave remanence, thermochroism, stimulation of mixed inorganic phosphors and photochroism.


In June 1957 the Auckland Harbour Board's bucket dredge Hapai over-turned and sank, in the Rangitoto Channel just outside Auckland Harbour. She was found lying with a considerable portion of her hull above water level at low tide. As no special salvage equipment or lifting vessels were available in New Zealand or Australia, the job was tackled using standard gear and winches which were readily available, together with lifting camels designed and built for this one job. This paper was published in New Zealand Engineering, February 1959 and presented to an Annual Conference of the New Zealand Institution of Engineers. The Dredge commenced working again in 1958 and continued dredging until 1965.


Objective To explore the relationships among professional identification,job satisfaction and turnover intention of emergency room nurses. Methods Totally 346 emergency room nurses from 11 upper first-class hospitals in Liaoning province were investigated with Professional Identification Scale,Nurses' Job Satisfaction Scale and Turnover Intention Scale. The data were analyzed by using SPSS 17.0 and Lisrel 8.8. Results The professional identification of emergency room nurses had positive correlations with the 9 dimensions of job satisfaction and had negative correlations with turnover intention. The total score and 9 dimensions of job satisfaction had negative correlations with turnover intention. The correlation coefficient between professional identification and turnover intention of emergency room nurses was -0.392. The correlation coefficient between job satisfaction and turnover intention was -0.375. The mediate effect of job satisfaction between professional identity and turnover intention was -0.09. Conclusion Professional identification is an excellent predictor of turnover intention. At the same time,job satisfaction plays partial mediate role in the relationship between professional identity and turnover intention.


Aggressive behavior is important for social insects because it makes possible for the colony to defend itself and the offspring from the action of invasive species. We studied the recognition and aggressiveness of the leaf-cutting ant Acromyrmex subterraneus subterraneus (Forel) to co-specific workers from other nest and heterospecific workers of Acromyrmex subterraneus molestans Santschi, Acromyrmex subterraneus brunneus (Forel) and Acromyrmex niger (Smith); and queens of their social parasite Acromyrmex ameliae De Souza, Soares and Della Lucia. Workers of other species were placed in contact with those of A. subterraneus subterraneus for three minutes and during this period the behavioral interactions were quantified. The aggressiveness index (AI) for each agonistic encounter was obtained. Acromyrmex subterraneus subterraneus workers exhibited greater aggressiveness against heterospecific than against conspecific competitors. Aggressiveness is connected to differences in the chemical profiles, which are larger in heterospecifics colonies.


We study periodic well-to-well flopping of rubidium atoms in one-dimensional grey optical lattices using a nondestructive, real-time measurement technique and quantum Monte Carlo wavefunction simulations. The observed flopping rates as well as flopping rates extracted from exact band structure calculations can largely be reproduced using adiabatic models that employ the Born-Oppenheimer approximation. The adiabatic model is greatly improved by taking into account a gauge potential that is added to the usual adiabatic light-shift potential. The validity of the adiabatic model allows us to interpret the observed flopping phenomenon as periodic well-to-well tunnelling. At low intensities and in related far-off-resonant optical lattices the adiabatic model fails. There, a weak-coupling model becomes valid, which describes the well-to-well flopping as a Rabi oscillation between weakly coupled states, but not as a tunnel effect.


Dynamic light scattering from aqueous solutions of initial and modified poly(vinyl alcohol) with 5% carboxyl groups was studied depending on the concentration and the duration of aging at room temperature. Differences in the character of aggregation of macromolecules in these solutions and in the sizes of the clusters formed were determined. The aggregation process in the solutions of initial poly(vinyl alcohol) proceeds more rapidly and the sizes of macromolecular aggregates and clusters are substantially larger compared to the solutions of modified poly(vinyl alcohol).


Gunja is a member of upavisha gana as therapeutic agent with high pharmacological and therapeutic attribute as root, leaves and seeds are used. The seeds are described as poisonous and useful in several diseases as skin disease, stiffness of shoulder joint, paralysis and other nervous diseases. According to some Ayurvedic literature Gunja is said to poisonous and should be given to the patient after Shodhana. Shodhana is procedures in Rasa Shastra by which a drug can be purified and a toxic drug can be detoxified. Several method of Shodhana has been mentioned in different text books on one member constituents. It does not provide the clue as which method is superior to the other and in what respect. The present study was carried out to establish the effective Shodhana process in red Gunja kernels. Red Gunja kernels (Rk) were subjected to Shodhana (Swedena –boiling) in cow's milk (RkM) and Kanji (sour gruel) (RkK) separately for six and three hours respectively. It was found that by the Shodhana process decreased in weight as compared to Ashodhit  Gunja kernels. The decrease was more in Kanji Shodhana. The colour was also changed from red to black and yellow in milk and Kanji respectively.


Dongnong 42,a photoperiod sensitive cultivar,was treated with 8 h and 16 h light illuminations,respectively.The leaf tissues were then sampled and two-dimensional gel electrophoresis(2-DE)was performed to separate the protein spots.The gels were stained with Coomassie Blue G-250.The difference between the protein maps of leaves from two different photoperiod treatments was analyzed with the PDQuest image software(Bio-rad).The liquid and ion trap mass spectrometry(LC-ESI-MS)was used to obtain the MS/MS of the differentially expressed proteins and the MASCOT software was used to search the protein database.A total of 16 differentially expressed proteins were identified,of them nine proteins showed up-regulation expression and four showed down-regulation expression.The major differentially expressed proteins,glutathione-S-transferase,disulfide isomerase,metalloproteinases,TCTP,Rieske iron-sulphur protein precursor cysteine synthetic enzymes,were reviewed and discussed.These proteins might be related to plant photosynthesis,signal transduction and apoptosis control,detoxification and plant defense and other physiological and biochemical function.


Abstract Spotted-wing drosophila, Drosophila suzukii (Matsumura), is a significant, global invasive species first confirmed in the United States in 2008. Since the first detection in Minnesota in 2012, D. suzukii rapidly became a major economic pest of berry crops in the state. Effective monitoring of adult D. suzukii populations is a crucial aspect of developing integrated pest management (IPM) programs for at-risk crops. Drosophila suzukii monitoring research was conducted in 2016 and 2017 to better understand the effectiveness of two commercially available trapping systems for early detection of adults in spring and how mean trap catches compared over time. In addition, using the Scentry trap, we assessed the impact of lure age on trap performance. Finally, a study was conducted to better understand the diurnal activity pattern for adult D. suzukii under Minnesota summer conditions. Results comparing the trapping systems indicated each system varied in its ability to detect first catch of D. suzukii but that both commercial traps/lures were effective. The lure age study showed that lures can be changed less frequently than initially suggested. Temporal activity studies, as measured by trap catch via Scentry traps, indicated that adult D. suzukii demonstrated a crepuscular activity pattern in raspberry and blueberry. The results of these studies should benefit growers as they continue to fine-tune fruit IPM programs for D. suzukii.


PURPOSE

To evaluate the implementation of the standardized nursing languages (SNL) of NANDA, NIC, and NOC at a midwestern baccalaureate nursing program over four years.

METHODS

Nursing faculty developed 6 items to rate responses using a Likert-type scale (1 = low to 5 = high.) Two open-ended questions were included. Faculty and student evaluations shared 4 common items, while 2 items were slightly different. Respondents' evaluations (juniors, seniors, and faculty) over 4 years were compared. Each year approximately 10 faculty and 60 students responded to the survey.

FINDINGS

Respondents rated the use of SNLs as follows: helpful as a resource (mean ≥4.0), pertinent to the course (mean ≥3.8), pertinent to clinical (mean ≥4.0), and compatible with Watson's Caring Theory (mean ≥4.0). Over 4 years, faculty members' ratings have increased while students' ratings have slightly decreased. Comments revealed the need for additional orientation and more in-depth discussion about relating SNLs to individualized patient care.

CONCLUSIONS

Continued research at this university, at other schools of nursing, and in practice settings is needed to evaluate student and faculty satisfaction after introducing standardized nursing languages in planning and documenting patient care.


Many of today's wireless sensor networks operate under the strict requirement that only a single sensor transmits data at a time. One way to guarantee this is to use protocols that detect and prevent package collisions on the MAC layer. These, however, come at the cost of increased transmission delays, reduced throughput and higher energy consumption. We propose a PHY layer approach to collision avoidance that is based on sequential detection and significantly reduces the risk of collisions while simultaneously minimizing the transmission delay. For this approach, a performance analysis is given whose results are shown to closely match numerical simulations.


In the infancy of radar, signal-to-noise ratio was a popular measure of the effectiveness of a radar receiving system for combating noise. Increased signal power, with respect to average noise power, made it easier to distinguish a signal from background noise. Further, the parameters of a target echo, such as amplitude, (range) delay, and doppler frequency shift, could be estimated more accurately with increased signal-to-noise ratio. It was apparent that both parameter estimation and detection were dependent on signal-to-noise ratio - at least in a qualitative sense.


This study aims to examine ways in which critical literacy strategies can be incorporated through music/lyric analysis in the social studies classroom to enhance instruction. Data was collected through field observation notes from created lesson plans, student work samples, teacher participant/student participant interviews and questionnaires. The study reveals that incorporating music disrupts the commonplace, using music can engage the reluctant learner, and using music provides students with different viewpoints on societal topics. Teachers must carefully select and analyze the song lyrics chosen as well as researching background information about the overall theme/time period of the song, and teachers need to incorporate a type of written reflection throughout the lesson to gauge if critical literacy practices are being implemented by students. INCORPORATING CRITICAL LITERACY THROUGH MUSIC 3 Incorporating Critical Literacy Strategies Through the Use of Music/Song Lyrics to Enhance Social Studies Instruction The use of Critical literacy practices should be implemented in all classrooms. Kurki (2015) found that incorporating critical literacy strategies with different types of texts that are familiar to students, such as music had positive effects for instruction in the classroom. Furthermore, according to Burstein (2014) incorporating the arts into the social studies classroom introduces students to cultural ideals and norms that are prevalent to their everyday lives. Burstein concluded that consciousness-raising through music allows students to value the customs, and traditions of others. Critical literacy techniques require students to "think outside the box" or to become immersed in a text/activity that might be "unknown" to them. According to Lewison, Flint, and Van Sluys (2002), critical literacy has been described in many different ways by many different theorists and literacy educators. These researchers have synthesized critical literacy into four dimensions: "Disrupting the commonplace, interrogating multiple viewpoints, focusing on sociopolitical issues, and taking action and promoting social justice" (Lewison, Flint, & Van Sluys, 2006, p. 382). Once teachers have decided to implement critical literacy practice into instruction they must find activities for critical literacy techniques to come out throughout the lesson. As mentioned, numerous action research has investigated the effectiveness of paring critical literacy with music/lyric analysis. According to Mangram and Weber (2012) music is one of the most widely used and appealing forms of communication. With that being said, teachers must take into consideration the likes and interests of their students. In doing so, students may become more engaged and involved with the specific content. INCORPORATING CRITICAL LITERACY THROUGH MUSIC 4 Simply put, if critical literacy strategies/approaches are not introduced in the classroom, students are not receiving a full education. As members of society it is paramount to be able to analyze a text for more than what is written. Students need to question a text, connect to a text, think about a text, and be inspired by a text. With that in mind, not all songs or music will accomplish this particular goal. Teachers must spend time selecting relevant music and lyrics. This practice is very beneficial specifically in the social studies content. Numerous songs have been written with explicit messages and ideas in the time period in which they were written. Social studies teachers must look at music as a text and should spend considerable time doing research to enhance instruction on the given time period being discussed in their social studies curriculum. This action research project asks: how does incorporating critical literacy strategies through the use of music/lyric analysis affect instruction in the social studies content? This specific action research project began under the guiding theoretical framework pertaining to critical literacy of Lewison, Flint, and Van Sluys (2006). Also, many leading research studies proved to promote the effectiveness of incorporating critical literacy strategies when paired with the use of music in the classroom. For this study, three lessons incorporating critical literacy with song lyrics were developed. A teacher participant taught the lessons to a group of three student participants. Data was collected through active observation, teacher/student participant interviews and questionnaires. When investigating multiple action researchers, this specific study was implemented to prove that pairing critical literacy strategies with music/lyric analysis was an effective method for social studies teachers to implement in the classroom. After the data was analyzed this action research found that incorporating critical literacy strategies through the use of music/lyric analysis positively affected instruction in the social studies content. It is essential INCORPORATING CRITICAL LITERACY THROUGH MUSIC 5 for teachers to carefully select the music that will be used for instruction. Secondly, the findings show that considerable preparation is required for teachers to create meaningful instruction centered around critical literacy strategies. Finally teachers must include some sort of written reflection throughout the lesson to gauge if critical literacy practices are being implemented by students during instruction. Theoretical Framework In today"s society, one of the more frequently discussed topics of education is that of literacy. According to Kucer (2009) "literacy itself can be defined as the way in which members of a society learn to effectively, efficiently, and simultaneously control the linguistic, cognitive, sociocultural, and developmental dimensions both orally and through written language and other mediums (p. 5). Many different writers in the world of education also have varying definitions of what exactly literacy is. Furthermore, according to Gee (2001) "literacy is the control of secondary discourses" (p. 23). In other words the ability to "use" or "function" with a person"s secondary discourse to effectively communicate. The specific aims of this particular study will be looking at the ways in which critical literacy strategies, specifically through music/lyric analysis can have a positive impact on social studies instruction. Before discussing a specific theoretical framework for this action research project, we must discuss the ways in which literacy is acquired amongst children. Numerous research has been done looing specifically at literacy acquisition. According to Kucer (2009) literacy is acquired by children through oral and written language development. As children begin to master oral language they are then able to better comprehend and learn written language. Another major factor that affects literacy acquisition is the environment in which a child is immersed in. Kucer also mentions that the people a child interacts with as well as the cultural norms/variation of that INCORPORATING CRITICAL LITERACY THROUGH MUSIC 6 specific environment greatly affect the way literacy acquisition for that particular child. Because people belong to different communities and cultures with different ways in which literacy is valued, taught, used and demonstrated, the interactions and the ways in which parents demonstrate literacy will be different. Another way in which literacy acquisition is different among children is through linguistic variation. Throughout the world, words can have different meanings and connotations. Literacy acquisition also is affected by cultural variation. From a broader stand point, we can see that the mastery of literacy is something valued in American society. To compete with other industrial nations, we value citizens to have basic literacy skills to be able to contribute in the work place. Furthermore, technology plays an important role in literacy acquisition. In today"s age children are immersed in technology. Different types of technologies are a primary discourse of many children in American society. With the advancements and affect technology/cultural variation have on literacy acquisition today, there are many different theoretical frameworks and ways in which literacy instruction should be implemented in school. When looking at this specific action research project, the theoretical framework to be guiding these particular activities must be that of critical literacy. When using critical literacy techniques and activities with music, Social studies teachers will be able to provide their students with very meaningful and thought provoking lessons and activities. As mentioned, the most beneficial and relatable theory to look through this specific lens would have to be critical literacy. The basic definition of critical literacy can be found in the root word: critical. Teachers must foster critical thought and analysis and analysis throughout instruction. According to Lewison, Flint, and Van Sluys (2006) the basis of critical literacy has taken on many different definitions and descriptions. Lewison, Flint, and Van Sluys report that INCORPORATING CRITICAL LITERACY THROUGH MUSIC 7 Definitions of what it means to be literate are shifting. Linguists, anthropologists, educators, and social theorists no longer believe that literacy can be defined as a concrete list of skills that people merely manipulate and use. Rather, they argue that becoming literate is about what people do with literacy—the values people place on various acts and their associated ideologies. In other words, literacy is more than linguistic; it is political and social practice that limits or creates possibilities for who people become as literate beings. (p. 199) Furthermore, in another article written by Lewison, Flint, and Van Sluys (2002), critical literacy has been described in many different ways by many different theorists and literacy educators. These researchers have s


Background and objective: Treatment of gout flares with uric acid-lowering medications is not optimal in hypertensive hyperuricemic patients and only sedates gout symptoms. The current study aimed to explore whether blood pressure control (BP) determines the symptomatic or asymptomatic status of hyperuricemic patients with elevated blood pressure. Patients and Methods: A cross-sectional study was conducted with 211 hypertensive hyperuricemic participants obtained from the King Saud Medical City (KSMC). All patients were categorized into three blood pressure groups: controlled, uncontrolled, and untreated hypertension groups. Based on uric acid (UA) levels, the participants were divided into three UA tertiles: T1, <157 µmol/L, T2:157-360 µmol/L and T3:>360 µmol/L. Descriptive statistics of the study variables and multivariate regression analysis were utilized to determine the association between gout joint flares and blood pressure after adjustment of the risk factors. Results: The findings revealed an increased prevalence of gout symptoms across the three BP groups. Moreover, this association was significant even after adjustment of the age, gender, BMI, and smoking. Also, there was a significant gout-symptoms difference when comparing the corresponding UA tertiles in each blood pressure group. Moreover, a significant positive association existed between blood pressure and the frequency and number of gouty attacks. The more controlled blood pressure, the less frequent and short-duration attacks. Conclusion: Hypertension was strongly suggested as a major risk factor in eliciting gout symptoms in hyperuricemic patients, whatever is the level of serum uric acid.


ABSTRACT Diabetes mellitus (DM) is metabolic syndrome signaled by hyperglycemic chronic and it contribute to several complication risk. Soya( Glycine max ) andGingger ( Zingiber officinale ) are used for the alternative theraphy of DM,however, the potency to regulate blood glucose level especially in it's combination has not been evaluated.The objective of this study to investigate anti-hyperglycemic effect of Glycine max ( G. max ) seed extract, Zingiber officinale ( Z. officinale ) rhizoma and it's combinationon diabetic rat. This study uses control group post test only with male spraque dawley rats divided into 2 control group and 3 test group (n=5 rats) . Diabetic rats was induced by High Fructose and Lipid Diet (HFLD) and multiple dose streptozotocin 25 mg/kg bw (i.p).The rat was administrated orally with G. max seed extract , Z. officinale and it's combination in dose of 5000 mg/kb bw, 500 mg/kg bw and 5000 : 500 mg/kg bwrespectively for 4 weeks . Blood sample were collected from the tail vein at 0, 30,60 and 120 minutes after oral glucose administration and thenit were measured using a commercially glucometer. The integrated area under the postprandial glucose curves (AUCs) was calculated by the trapezoidal method. The data was analyzed using ANOVA test continued with LSD test (p < 0,05). The oral administration of G. max seed extract, Z. officinale and it's combinationwere able to decrease blood glucose AUC about 30 %, 35 % and 35 % respectively compared to diabetic group (p<0.05). In diabetic groups, blood glucose AUC was increased approximately 1.5-fold compared to normal group (p<0.05). Single composition of Z. officinale extract and its combination with G.max decrease blood glucose AUC more compared to the single composisition of G. max seed extract after glucose stimulation. Key words : AUC, Combination, Diabetic, G. max, Z. officinale

How teaching excellence issues enter the vision of decision makers is the key to understanding why the latest policies for excellence in teaching are being released quickly. This paper adopts the perspective of multi-source flow model to analyze the policy of excellent teaching. The research shows that the previous excellent policy lays a foundation for the release of the new policy, and the relevant student surveys bring the excellent teaching to the forefront; different stakeholders provide from different angles. Views and suggestions; national sentiment and the change of government officials are also the driving force for excellence in teaching events; ultimately, under the softening effect of government entrepreneurs, the three streams will be merged to achieve policy development. 多源流理论视角下英国高等教育卓越教学政策解析

ABSTRACT The threats of ethnic, religious, and ethno-religious conflicts have endured in Nigeria and become increasingly alarming in the fourth republic, which started in 1999. Ethno-religious conflicts are hostile engagements where actors and their motivations reflect a combination of ethnic and religious interests. These conflicts are deeply rooted in colonial legacies, ethno-religious-based distributions of power and resources, and failure of the post-colonial state to advance unity in diversity and promote the welfare and security of all citizens without discrimination. Between 1999 and 2021, Nigeria recorded no fewer than 2811 incidences of ethnic conflict with 18,132 fatalities, 3703 incidences of religious conflict with 29,957 fatalities, and 117 incidences of ethno-religious conflict with 2420 fatalities. These conflicts have had negative consequences for the lives and properties of the affected population, political stability, national unity, integration, development, security, and the image of the country internationally. This article examines the threats of ethno-religious conflicts in Nigeria's fourth republic, their causes, manifestations, consequences, and possible ways forward.


Unlike current satellite laser ranging stations, the SLR2000 systems are to run autonomously, requiring no operator intervention or control on a regular basis. However, during the initial system development and debugging as well as during regular maintenance and upgrades of these stations, some type of human interface beyond a shell prompt will be required. To fulfil this need the Remote Access Terminal (RAT) is being developed. It will allow the operator to examine current ranging system status and faults, display current and recent data of many types, and override system operating parameters and decisions. This is accomplished by running an X windows/Motif-based graphical interface program on a laptop computer connected via the internet. The RAT accesses the SLR-2000 system via an information and command server on the the SLR2000 Data Analysis system (DAN) across a Berkley socket interface and via Network File System (NFS). The RAT is being built for a PC laptop running the freely available Unix-like operating system Linux (Red Hat distribution).

of Karna's "flawed" lineage. As the performance is coming to a close, de Bruin records how the kattiyakkaran offers a water libation to the gods and ancestors, not only for the character of Karna in the play, but also in the presence of the son of the deceased, Tiru Elappan, the male villager for whose funeral rites the performance has been commissioned. The dramatization of the ceremony marks not only the release of Karna's soul in the world of the play but also that of the villager. (One minor, though bothersome, fault of the translation is the irksome printing problem caused by the insertion of diacritics in the introduction.) Together these two volumes constitute an excellent contribution to the all too limited list of full-length studies of South Asian theatre traditions and their texts-in-performance. They will stand as a model of thorough, thoughtful, and accessible description, analysis, and translation. For those teaching South Asian performance, adding a videotape of at least parts of a performance of Karna's Death would be a further invaluable contribution.


A scheme is presented to generate atomic entanglement by detecting the transmission spectrum of a coupled-cavity system. In the scheme, two 3-level atoms are trapped in separate cavities coupled by a short optical fiber, and the atomic entanglement could be realized in a heralded way by detecting the transmission spectrum of the coupled-cavity system.


Fluorocarbon polymer films were prepared by plasma polymerization using nitrogen trifluoride (NF3) and propylene as starting materials. To improve their adhesiveness to substrates, a novel functionally gradient film in which the content of fluorine decreased continuously from the surface to the interior was prepared by changing source gas composition during deposition.

ABSTRACT This study investigates a widespread yet under-researched phenomenon on social media: being envied. From the perspective of social interaction, we examine how the envy in reviews affects the posters' eWOM intention. The results of a pilot study and three experiments revealed that posters' perception of being benignly (maliciously) envied will increase (decrease) their eWOM intention, and the effect is stronger (weaker) when posters and reviewers have strong (weak) ties. Compared with people focusing on promotion, those focusing on prevention showed a higher level of anxiety and lower self-confidence when being envied. Self-confidence (anxiety) has a mediating effect between being benignly (maliciously) envied and eWOM intention, while the mediating effect of anxiety is only significant in two conditions: (1) strong ties and (2) prevention orientation. Our findings are of great significance for marketers to optimize online word-of-mouth marketing strategies and encourage consumers to spread eWOM on social media.


ABSTRACT In general, conventional Optimal Power Flow(OPF) solutions utilize some optimization techniques at a single case. In the OPF solution method, all the available variables are used to solve the problem. In practical operation, such a solution is not a practical consideration because the control actions would be too many to be implemented. In this paper, sensitivity factors combined with dynamic programming technique are used to solve short term (one day) dynamic optimal power flow. A two-step real time real power dispatch method considering inconforming load change is used to solve real power dispatch, and then, the sensitivity factors are used to solve reactive power dispatch with some constraints. Finally, the dynamic programming technique is used to minimize the control actions to as little as possible. The advantages of this method are simple and easy to implement, and it would greatly enhance the operators' planning.


Thank you very much for your very kind invitation to present a new project and some ideas concerning TP (telepathology) at this meeting. It is a great honour for me as an pathologist leading a small private institute in a small medieval town in a remote and very peaceful countryside, Aurich, Germary (Fig.1). I want to speak about DIAGAID (Fig.2) because this project is reflecting the possibilities as well as the limits of telepathology and telecytology 1•`3). DIAGAID is a partnership in diagnostic aid founded at the Vth European congress on Telepathology 2000 in Aurich at a round table discussion between participants of developed and developing countries (Fig. 3). There is no sharp delineation between developing and developed countries because in some senses we are always living in a developing sociery. The aim of this project is the exchange and communication in respect to diagnostic help, experience, quality control and establishing personal and institutional networks in medical care via telepathology. Development of medical networks seems to be necessary if we look at Fig.1


Cognitive radio is a promising paradigm for efficient utilization of the radio spectrum due to its capability to sense environmental conditions and adapt its communication and localization features. In this paper, the theoretical limits on time-of-arrival estimation for cognitive radio localization systems are derived in the presence of interference. In addition, an optimal spectrum allocation strategy which provides the best ranging accuracy limits is proposed. The strategy accounts for the constraints from the sensed interference level as well as from the regulatory emission mask. Numerical results are presented to illustrate the improvements that can be achieved by the proposed approach.


What are causes of conflict between religious groups? This chapter focuses on believers' perceptions of the causes of interreligious conflict. What do Christian, Muslim and Hindu students perceive as possible causes of religious conflict? What situations potentially contribute to religious conflict, according to these students? Perceptions of causes of conflict are not objective descriptions of facts. They are interpretations based on the (re)definition of the respondents' religious identity, on the (re)affirmation of the authority of their religious tradition, and most likely also reflect their circumstances in terms of level of anxiety and uncertainty (Sidel 2007, 1–17). Often God as the ultimate reality and final authority is advanced as the motive for religious involvement in (destructive) conflict. The violent face of religion is evident in its politicization in nationalism, its radicalization as fundamentalism, and its instrumental use by terrorism. No religion is free from such ambiguous features, given the close link between religion and the economic, political and social domains. In India the three major religions have been, and in some cases continue to be, sources of violent conflict. Christianity's close link with those who colonized and dominated the Indian subcontinent in the latter half of the second millennium and the existence of contemporary Christian fundamentalist groups demonstrate the conflictive features of Christianity. Similarly, the spread of Islam through invasion and conquest since the 8th century CE and the present instrumentalization of Islam by terrorist groups in India reveal the conflictive side of Islam. And Hinduism, which in all its varied forms has inspired the vast majority of Indians over three millennia, was not totally free from violence. For example, the attacks by Saiva sects on the flourishing Jain and Buddhist communities in South India since the 7th century ended with their disappearance from Tamil Nadu. Some Hindu fundamentalist groups are also responsible for sporadic violence on the Indian subcontinent today. To gain empirical insight into the causes of religious conflict we proceed as follows. In section 7.2 we identify four types of causes of conflict between religious groups: economic, political, ethnic-cultural and religious causes. Section 7.3 presents the empirical research, starting with the research questions, fol-

The Orbiter camera payload system (OCPS) is an integrated photographic system carried into earth orbit as a payload in the Space Transportation System (STS) Orbiter vehicle's cargo bay. The major component of the OCPS is a large-format camera (LFC), a precision wide-angle cartographic instrument capable of producing high-resolution stereophotography of great geometric fidelity in multiple base-to-height ratios. A secondary and supporting system to the LFC is the attitude reference system (ARS), a dual-lens stellar camera array (SCA) and camera support structure. The SCA is a 70 mm film system that is rigidly mounted to the LFC lens support structure and, through the simultaneous acquisition of two star fields with each earth viewing LFC frame, makes it possible to precisely determine the pointing of the LFC optical axis with reference to the earth nadir point. Other components complete the current OCPS configuration as a high-precision cartographic data acquisition system. The primary design objective for the OCPS was to maximize system performance characteristics while maintaining a high level of reliability compatible with rocket launch conditions and the on-orbit environment. The full OCPS configuration was launched on a highly successful maiden voyage aboard the STS Orbiter vehicle Challenger on Oct. 5, 1984, as a major payload aboard the STS-41G mission.

Background:
 Patients with symptomatic intracranial stenosis (ICAS) face elevated risks of recurrent cerebrovascular events (RCE) despite optimal medical therapy. Borderzone infarcts (BZI) indirectly correlate with impaired distal perfusion, a known mechanism of recurrence. Studies assessing associations between borderzone infarcts and recurrence rates are observational and have relatively small sample size. We therefore performed a meta-analysis of published studies investigating this association.

 Methods:
 We performed a Medline and Web of Science search using the key words (Intracranial Atherosclerosis OR Intracranial Stenosis) AND (Borderzone OR Infarct Pattern) to identify studies reporting associations between index infarct pattern and RCE, defined as recurrent ischemic stroke or neurological deterioration, or new infarct on follow up neuroimaging in patients with symptomatic ICAS. We included relevant papers and scientific abstracts with more than 20 patients included. For all outcome events we calculated the corresponding risk ratios (RRs) and 95% confidence intervals (95% CI).

 Results:
 We identified 178 studies using Web of Science and 384 studies using Medline with only 6 studies (591 patients) meeting our inclusion criteria (2 prospective and 4 retrospective). The weighted proportion of patients with BZI was 32.5% (28.7%-36.4%). During a follow-up period of 7-950 days, 33.1% (26.3%-40.5%) of patients with BZI had RCE and 63.6% (30.8%-89.1%) had new infarction on a 6-8 week follow up brain MRI. In meta-analysis, BZI was associated with increased rates of RCE (RR 2.40 95% CI 1.71-3.37) and new infarct(s) on follow up brain MRI (RR 2.55 95% CI 1.31-4.94). The findings were unchanged when the analysis was limited to 90-day RCE risks only (RR 2.22 95% 1.49-3.29).

 Conclusions:
 BZI are associated with over 2-fold increased risk of RCE and recurrent infarct in patients with symptomatic ICAS. Prospective studies are needed to validate these findings.


RATIONALE
During the development and validation of mass spectrometry based method in residue control analysis, it is recommended to evaluate the level of the matrix effect. Often its level is relatively high, despite extensive sample purification.

METHODS
The matrix effect in the method for the determination of non-steroidal anti-inflammatory drugs in animal muscle was tested using a post-extraction addition technique. The experiment was performed to assess the impact of chromatographic conditions and design of ion source on the results. Additionally, the impact of phospholipids was tested.

RESULTS
The matrix effect signal varied from 36% (64% ion suppression) to 192% (92% ion enhancement), depending on the analyte and species. The internal standard corrected matrix effect was generally lower but was still high for some analytes. Both chromatographic conditions and ion source design have influence on the level of matrix effect; however, this effect was no longer observed after compensation with internal standards.

CONCLUSIONS
Currently, no commonly accepted criteria exist for the interpretation of results of determination of matrix effects; such criteria have been proposed in this paper, based on guidelines for bioanalytical methods and results of the study.


The aim of this paper is to explore the autobiographical and theoretical forms of entry in Walter Benjamin's essay Berlin childhood, and, on the other hand, to present a diverse/flexible/ hybrid theory by which is realized a meaningful framework of analysis. According to this, the contextual interpretation of the story The Sock is, in fact, an intertextual play between autobiography (text!) and theory (footnote!).


Since the original description, in 1926, of the displacement method for instilling fluids into the paranasal sinuses,' this method has enjoyed widespread acceptance in the treatment of sinus disease. It will be the purpose of this paper not to discuss or evaluate the efficacy of displacement therapy, but to present a simplified method of displacement for those who wish to instill fluids into the sinuses.


The influence of β carotene on the fluorescence yield of chlorophyll a in 3‐methoxy‐ 1‐butanol is investigated. β carotene does not affect the fluorescence yield when chlorophyll a is excited in the red absorption band at 660 nm. However, a quenching of the red fluorescence of chlorophyll a is observed when excited at 415 nm. This is suggested to be due to a quenching of the second excited state of chlorophyll a by β carotene.


The provisions of the German financial equalization system (Landerfinanzausgleich), a specific form of a fiscal union among the federal states (Lander), will expire in 2019. In this paper, we assess the effects of the system as well as of reform proposals on key macroeconomic variables and welfare by means of a two-region general equilibrium model. We find that, on the one hand, as expected, abolishing tax revenue equalization would favor transfer paying states in terms of GDP and consumption, and significantly hurt receiving states. Furthermore, households living in the financially strong states would benefit from higher wages and more leisure. This induces migration towards these states. On the other hand, on aggregate, the average German household's welfare would be negatively affected, even though those who live in the paying states would gain. However, the negative macroeconomic effects involved by the abolition of the equalization transfers might potentially be countervailed by the concomitant reduction in disincentive effects for the budgetary policy.


Protective immune responses to Chlamydia infection within the female reproductive tract (FRT) are incompletely understood. MHC class II-restricted IFN-γ+ Th1 responses are thought to be vital for bacterial clearance, but the Th1 master transcription factor T-bet had not yet been fully interrogated in primary infection. Here, we investigated T-bet and IFN-γ involvement in clearance of primary infection from the FRT. Surprisingly, IFN-γ producing CD4+ T cells from the FRT expressed low levels of T-bet, indicating that Chlamydia-specific CD4 T cells are not classical T-bet+ Th1 cells. Additionally, mice deficient in T-bet competently cleared infection with wild-type kinetics and showed significant skewing towards Th17 responses, indicating compensation pathways through alternate Th fates. On the other hand, IFN-γ-, and IFN-γR-deficient mice resolved much of FRT infection, but displayed systemic dissemination and 100% mortality. Thus, IFN-γ protects mice from fatal systemic disease, but classical T-bet+ Th1 cells are not required for primary clearance. In investigating alternative Th fates, RORγt mutant mice deficient for Th17 responses exhibited a short delay in clearance of FRT infection, demonstrating an unanticipated role for Th17 cells in Chlamydia clearance. However, mice deficient in the cytokine subunit IL-12p40 that promotes both Th1 and Th17 cells displayed a prolonged delay in FRT clearance despite CD4 T cells retaining the capacity for IFN-γ production. In summary, the type 1 cytokine IFN-γ plays an essential role in systemic control of Chlamydia, while clearance of primary infection within the FRT is largely dependent on an IL-12p40 driven mechanism that does not require T-bet or classical IFN-γ producing Th1 cells.

The oxidative deamination of oral propranolol has been studied in dogs by mass fragmentography. Isopropylamine and hexadeuterated isopropylamine were identified as urinary metabolites of propranolol and hexadeuterated propranolol, respectively. This is the first example of a one-step deamination of an N-isopropylamino compound. Criteria of identity include: two specific fragment ions, their relative intensity and the retention time compared to a reference compound. The specificity provided by stable isotope labeling is demonstrated. Isopropylarnine exerts cardiac as well as peripheral vascular effects.

Abstrac: This article explores the inequality and social exclusion that it suffers from the population of the region Sierra, Chiapas, in the field of health. Addressed from the testimonies of rural women who offer their own vision of health, disease and health care, and develop different strategies for dealing with the difficulties. It is intended to demonstrate how in an adverse environment, characterized by poverty and institutional neglect,, physical disorders are repeatable, become incurable and they contribute to the reproduction of marginality. Thus arises the disease of the poverty, which somatizes physical ills to express social deprivation.


Dr. Langford: It seems to me that sodiuminduced calcium loss is an important part of the "feed forward" that produces hypertension, and also to a lesser extent, sodium-induced potassium loss. I would perhaps now be willing to buy that if we are going to take a large sodium intake, we have to have very high calcium and potassium intake to block the consequences of sodium. We may be able to do that successfully. I suggest this for provocative reasons. Dr. McCarron: I think Harvey Gruchow, in his National Health and Nutrition Examination Survey (NHANES) data base, pointed out that the level of dietary calcium is not that high. But it is still a level that many people in this country are not consuming. In spite of Dr. Kuller's view, potassium intake is still low in many of the same people. Professor R. Stamlen In some of the studies that we are doing, including interventional or observational, I question whether we are getting a real handle on actual sodium intake if we use the method of dietary recall—this only addresses discretionary addition of salt at the table and in cooking, and that varies considerably in different populations. I wondered what the estimate is of the percentage of sodium intake or salt intake that comes from nondiscretionary use. In the United States I think the estimate is that about 75% comes from nondiscretionary use. It is forced on us. In England I think it is 85%.


The crimping quality of steel cored aluminum strand for overhead transmission lines has a direct influence on the safe and stable operation of lines. The common crimping quality problem of splicing sleeve is analyzed in this paper. It is indicated that the core issues of crimping of steel cored aluminum strand is the inaccurate crimping positioning of the aluminum tube of splicing sleeve. At present, there is no effective and convenient nondestructive method to implement quality supervision during crimping process. Aiming at the above problem, magnetic detection can be used to indicate the relative position between the non-crimped area of steel and aluminum tubes since they have different magnetic properties. We propose to strengthen the crimping quality supervision of steel cored aluminum strand in order to ensure the safe operation of transmission lines.

The acute clinical repercussions of SARS-CoV-2 infection have been widely studied. However, the possible late repercussions of long COVID have not yet been well defined in the literature.To identify the presence of pain and musculoskeletal disability in patients with Long COVID and also to identify predictive factors for pain intensity in this population.In this cross-sectional and retrospective observational study individuals with Long COVID symptoms were included. It was collected musculoskeletal disability measures, data from patient-related outcome measures and variables from a COVID-19 outpatient service database. Associations and sub-group analyses were performed considering the variables pain, disability and hospitalization. Linear regression was performed to identify predictive factors for pain intensity in Long COVID patients.We evaluated 195 patients and most of them (57%) presented musculoskeletal pain in one area of the body. Pain sub-group presented worse disability indices and worse clinical course during hospitalization. Hospitalized patients presented worse disability indices comparing to non-hospitalized. Significant correlations were found between pain and days of non-invasive oxygen support (r = 0.21; p = 0.003); days in intensive care unit (r = 0.22; p = 0.002) and days in invasive mechanical ventilation (r = 0.35; p = 0.001). Hospitalized individuals showed a higher chance of presenting late musculoskeletal pain (OR = 1.42: 95%CI 1.09–2.04). Days in intensive care unit (β = 0,234: P = 0,001) and days in invasive mechanical ventilation (β = 0.764: P = 0.001) were predictors of pain intensity [F(2,192) = 18.559; R2 = 0.231; p = 0.001].Individuals with Long COVID presented musculoskeletal pain and disability. Hospitalized patients showed a greater chance of having musculoskeletal pain. Days in intensive care unit and days in invasive mechanical ventilation were predictors of late musculoskeletal pain intensity.


Update in urinary tract infection in pediatrics urinary tract infection (uti) is a common infectious disease in children. t raditionally uti has been conside- red as a marker of underlying anatomical or functional urological abnormalities. in the last decades all children with febrile uti were recommended to undergo imagenological studies looking for renal scarring or urinary tract abnormalities. the goal of this article it is to update the concepts of febrile uti studies, treatments and follow-up. the imagenological studies are unpleasant for children and distressing for their parents. current data do not provide enough evidence about the effectiveness of broad studies in uti, therefore physicians should be more selective in order to find out patients who requiere surgical or medical intervention. These recommendations are based on nice guidelines and support the concept that one of the most important issues


Background: Studies show that traditional teaching methods, such as lecturing, do not lead to in-depth learning. Concept maps have been used for a long time by researchers and teachers to facilitate learning. Objectives: The present study aimed to investigate the effect of concept mapping on the learning levels of students in nursing care of patients with glandular diseases subject in Urmia University of Medical Sciences. Materials and Methods: In a quasi-experimental study with a pre-test/post-test design, 28 nursing students were selected and divided into two groups: the experimental and the control groups. After administration of pre-test, the students in the experimental group participated in classes on designing concept maps. Next, lessons on glands and nursing were presented to the students in the experimental and control groups through concept maps and lectures, respectively. At the end of the semester, the learning levels of the students in both groups were evaluated by the post-test. Results: The means of the scores of the students as determined by results of the pre-test revealed insignificant statistical difference between the two groups. However, the learning level of the students in the experimental group was significantly higher (P < 0.05). As a metacognitive intervention, concept mapping can contribute to in-depth learning of nursing students. Conclusions: According to the findings, it is recommended that concept mapping should be used for teaching and evaluation. Further studies are needed to compare the effect of concept mapping with those of other metacognition approaches on different types of learners.


Based on guidance scheme of antagonism against the radar stopping radiating using the strapdown inertial navigation system and antiradar seeker,the application of finite-difference extended Kalman filter(FDEKF) to passive localization of target is studied.Considering nonlinear characteristic of the antiradar seeker,a method of extending dimensions of state variables was present to achieve estimation of target's state and compensation of nonlinear characteristic of the antiradar seeker.The result of simulation shows that the FDEKF has good performance and can be used as nonlinear filter instead of traditional method of EKF to solve the problem of passive localization to a target.

CPU time of generating CNF and the traversing space are reduced.This algorithm gain compact test set with low price.


Development of resistance to current antimalarial therapies remains a significant source of concern. To address this risk, new drugs with novel targets in distinct developmental stages of Plasmodium parasites are required. In our current work, we have targeted P. falciparum Tubulin (PfTubulin) proteins which represent some of the potential drug targets for malaria chemotherapy. Plasmodial Microtubules play a crucial role during parasite proliferation, growth, and transmission, which render them highly desirable targets for the development of next-generation chemotherapeutics. Towards this, we have evaluated the antimalarial activity of Tubulin targeting compounds received from the Medicines for Malaria Venture (MMV) "Pathogen Box" against the human malaria parasite, P. falciparum (including 3D7, RKL-9 (Chloroquine resistant) and R539T (Artemisinin resistant) strains). At nanomolar concentrations, filtered out compounds exhibited pronounced multistage antimalarial effects across the parasite life cycle, including intra-erythrocytic blood stages, liver stage parasites, gametocytes and ookinetes. Concomitantly, these compounds were found to impede male gamete ex-flagellation, thus showing transmission-blocking potential of these compounds. Target mining of these potent compounds, by combining in silico, biochemical and biophysical assays, implicated PfTubulin as their molecular target, which may possibly act by disrupting microtubule assembly dynamics by binding at the interface of α-βTubulin-dimer. Further, promising ADME profile of the parent scaffold supported its consideration as a lead compound for further development. Thus, our work highlights the potential of targeting PfTubulin proteins in discovering and developing next-generation, multistage antimalarial agents for treating Multi-Drug Resistant (MDR) malaria parasites. GRAPHICAL ABSTRACT


The discovery of the Spectre attack in 2018 has sent shockwaves through the computer industry, affecting processor vendors, OS providers, programming language developers, and more. Because web browsers execute untrusted code while potentially accessing sensitive information, they were considered prime targets for attacks and underwent significant changes to protect users from speculative execution attacks. In particular, the Google Chrome browser adopted the strict site isolation policy that prevents leakage by ensuring that content from different domains is not shared in the same address space. The perceived level of risk that Spectre poses to web browsers stands in stark contrast with the paucity of published demonstrations of the attack. Before mid-March 2021, there was no public proof-of-concept demonstrating leakage of information that is otherwise inaccessible to an attacker. Moreover, Google's leaky.page, the only current proof-of-concept that can read such information, is severely restricted to only a subset of the address space and does not perform cross-website accesses. In this paper, we demonstrate that the absence of published attacks does not indicate that the risk is mitigated. We present Spook.js, a JavaScript-based Spectre attack that can read from the entire address space of the attacking webpage. We further investigate the implementation of strict site isolation in Chrome, and demonstrate limitations that allow Spook.js to read sensitive information from other webpages. We further show that Spectre adversely affects the security model of extensions in Chrome, demonstrating leaks of usernames and passwords from the LastPass password manager. Finally, we show that the problem also affects other Chromium-based browsers, such as Microsoft Edge and Brave.


The unitary isobar model MAID2007 has been developed to analyze the world data of pion photoand electroproduction. The model contains both a common background and several resonance terms. The background is unitarized according to the K-matrix prescription, and the 13 four-star resonances with masses below 2 GeV are described by appropriately unitarized Breit-Wigner forms. The data have been analyzed by both single-energy and global fits, and the transverse and longitudinal helicity amplitudes have been extracted for the four-star resonances below 2 GeV. Because of its inherent simplicity, MAID2007 is well adopted for predictions and analysis of the observables in pion photoand electroproduction. PACS. 11.80.Et , 13.40.-f, 13.60.Le, 14.20.Gk

Let C be a pointed closed convex cone in R n with vertex at the origin o and having nonempty interior. The set A ⊂ C is C -coconvex if the volume of A is finite and A • = C \ A is a closed convex set. For 0 < p < 1, the p -co-sum of C -coconvex sets is introduced, and the corresponding L p Brunn-Minkowski inequality for C -coconvex sets is established. We also define the L p surface area measures, for 0 (cid:54) = p ∈ R , of certain C -coconvex sets, which are critical in deriving a variational formula of the volume of the Wulff shape associated with a family of functions obtained from the p -co-sum. This motivates the L p Minkowski problem aiming to characterize the L p surface area measures of C -coconvex sets. The existence of solutions to the L p Minkowski problem for all 0 (cid:54) = p ∈ R is established. The L p Minkowski inequality for 0 < p < 1 is proved and is used to obtain the uniqueness of the solutions to the L p Minkowski problem for 0 < p < 1. For p = 0, we introduce (1 − τ ) (cid:5) A 1 ⊕ 0 τ (cid:5) A 2 , the log-co-sum of two C -coconvex sets A 1 and A 2 with respect to τ ∈ (0 , 1), and prove the log-Brunn-Minkowski inequality of C -coconvex sets. The log-Minkowski inequality is also obtained and is applied to prove the uniqueness of the solutions to the log-Minkowski problem that characterizes the cone-volume measures of C -coconvex sets. Our result solves an open problem raised by Schneider in [Schneider, Adv. Math., 332 (2018), pp. 199-219]. Subject Classification: 53A15, 52B45, 52A39.

In this chapter and the next we discuss the curve shortening flow (CSF). A number of important techniques in the field of geometric flows exhibit themselves in the curve shortening flow in an elegant and less technical way. The CSF was proposed in 1956 by Mullins to model the motion of idealized grain boundaries. In 1978 Brakke studied the mean curvature flow, of which the CSF is the 1-dimensional case, in the context of geometric measure theory. Renewed interest in the CSF resulted from the works of Gage and Hamilton in 1986 on convex plane curves and Grayson in 1987 on embedded plane curves. In this chapter and throughout the rest of the book we shall assume that the objects we consider are smooth, i.e., C1. This assumption is made more out of convenience than necessity and we refer the reader to the notes and commentary at the end of this chapter for references to results with weaker regularity hypotheses.


Fake news has become one of the most serious issues in recent years, especially on social media. For example, during the covid-19 pandemic, a great deal of false information about the virus spread easily and quickly through the internet. In this area, researchers have given substantial answers to this problem utilizing various machine learning techniques. However, there are some gaps that need to be clarified. In the context of COVID-19 fake news detection, in this study, we present a comparison of four major machine learning algorithms: SVM, Nave Bayes, Logistic Regression, and Random Forest. We proposed four new machine learning models by combining these algorithms with two feature extraction techniques (TF-IDF and CountVectorizer). On three datasets, we tested the suggested models and analyzed their performance. According to the obtained results, we concluded that some properties of the used datasets can a ff ect the obtained results. In addition, we find the best model overall.

The accurate determination of the thermoelectric properties of a material becomes increasingly difficult as the temperature rises. However, it is the properties at elevated temperatures that are important if thermoelectric generator efficiency is to be improved. It is shown that the dimensionless figure of merit, ZT , might be expected to rise with temperature for a given material provided that minority carrier conduction can be avoided. It is, of course, also necessary that the material should remain stable over the whole operating range. We show that the prediction of high temperature properties in the extrinsic region is possible if the temperature dependence of carrier mobility and lattice thermal conductivity are known. Also, we show how the undesirable effects arising from mixed or intrinsic conduction can be calculated from the energy gap and the relative mobilities of the electrons and the positive holes. The processes involved are discussed in general terms and are illustrated for different systems. These comprise the bismuth telluride alloys, silicon-germanium alloys, magnesium-silicon-tin and higher manganese silicide.


Child marriage remains a widely ignored violation of health in addition to development rights of girls and young women. Child marriage is often associated with multiple health risks. The majority are exposed to early and frequent sexual relations; repeated pregnancies and child-birth before they are ready to shoulder the responsibilities of marriage and childbearing. As a result, different diseases, health complication, maternal death, abnormal childbirth etc. are being associated with this practice. Early marriage is a common practice in Malda, a district of West Bengal. In the latest District Level Household Survey (DLHS-3) in 2007–08, the percentage of child marriage in Malda district is 56.7 per cent having 2nd rank in the state. In this study attempt has been made to analyze and map the spatial distribution of this practice and also to reveal its harmful consequences on health. Finally, perception survey has been conducted to find out the causes of its perpetuation.


In the past decade, there have been a number of notable changes in industrial software engineering, including the movement towards agility. The Agile Manifesto characterizes the term "agile", and lists a set of principles that form a basis for agile methodologies [1], such as Extreme Programming (XP), OpenUP, and Scrum. There is creation, communication, and consumption of knowledge during (agile) software development [2]. For the success of an agile project, it is crucial that such knowledge be managed effectively. In doing so, an appropriate selection and use of certain tools and technologies can be helpful. In the past few years, there has been a proliferation of Social Web Applications, such as Wiki [3]. Indeed, a number of noteworthy uses of Wiki in software engineering have been reported [4]. However, these studies are largely independent of any software development methodology, and are centered mostly on collaboration. The primary reasons for selecting Wiki for agile software development include the following: (1) the deployment of agile methodologies, especially XP and Scrum, with teams that are increasingly geographically-dispersed, (2) the involvement in sustainable software development by organizations with basic infrastructure and modest budgets for resources, and (3) the need of inexpensive, mature, and widely-available tools for supporting iterative development, by almost anybody, at anytime, anywhere, using almost any device. The purpose of this research is to provide a framework for integrating Wiki for the purpose of facilitating the dynamics of knowledge during agile software development.


Internet of Things (IoT) is a concept that utilizes an internet network that is always connected among some devices. Internet of Things requires a protocol to get the information quickly and in real-time to exchange the data needed, one of them is ESP-NOW. ESP-NOW protocol is a communication protocol that is able to send data over long distances, with relatively fast transfer speeds. In addition, the technology that is developing rapidly at this time is the development of robots. A robot is a tool or technology used to facilitate human work. In this research, an IoT-based robot was developed to perform maintenance on various types of soil in accordance with optimal parameters. The robot can monitor the soil conditions and water the plant automatically. The robot monitors the temperature and humidity of the air, as well as the humidity of the agricultural soil. The desired crop condition is 70% for the minimum air humidity threshold and 60% for the minimum soil moisture threshold. The robot is also equipped with a GPS module to store the initial location of the robot. The test was conducted at 6 points, where all points were in the desired condition after 3 times of testing. The robot also uses ESP-NOW as the communication protocol to send necessary information in real-time such as agricultural soil data. The success rate of messages received by the ESP-NOW gateway at a distance of 0.5 up to 3 meters from the sender is 100%.


The present article illustrates the experimental results of investigation of antiradical defense system state at conditions of crown-ethers action upon the organism of warm-blooded animals. The research program used sub-acute toxicological experiment on sexually mature white male rats of WAG population (body mass - 180-220 g). The animals were administered with water emulsion of investigated crown-ethers (12-crown-4, 15-crown-5, and 18-crown-6) in 1/100 and 1/1000 LD50 daily, within 30 days perorally. The animals of the control group were given water at the same conditions. On the 30th day of the experiment the rats of all groups were anesthetized by sodium thiopental (50 mg/kg) and slaughtered by decapitation with the Guillotine knife. Oxidantantioxidant interaction was evaluated using the following indexes: SH-groups, vitamin C, vitamin E contents; haptoglobin, MDA, and DC concentrations; ceruloplasmin, catalase, peroxidase, SOD, GP activities. All crown-ethers 1/1000 LD50 (subtoxic dose) increased blood serum contents of DC by 80.1; 75.4; 70.2% and MDA 108.9; 130.8; 82.4% for 12-crown-4, 15-crown-5, 18-crown-6, respectively. Their action also resulted in enhancing the activity of investigated antioxidant system enzymes – blood catalase (by 35% on average), blood peroxidase (by 80% on average), blood GP (by 60% on average) and blood SOD (by 40% on average). Crown-ethers significantly increased concentrations of serum ceruloplasmin (by 85% on average) and haptoglobin (by 82% on average). The concentration of the main antioxidant peptide glutathione (reduced form) was higher in blood of the experimental rats, whereas the general contents of SH-groups became diminished. The contents of adrenal gland vitamin C got increased (by more than 40%) in the action of crown-ethers on the background of decreasing in serum vitamin E concentration. The action of 12-crown-4, 15-crown-5 and 18-crown-6 1/100 LD50 resulted in the pronounced increase in blood serum contents of DC by 152; 138; 144% and MDA by 178; 162; 154%, respectively. The blood contents of SH-groups did not significantly changed at the influence of the investigated compounds. This dosage of crown-ethers further activated free-radical processes and lipid peroxidation, inhibiting antioxidant system, which was connected with membranes pathology development being at the base of structure-metabolic disturbances in different organs and tissues of the organism. Key words:  crown-ethers, free-radical oxidation, lipid peroxidation, antioxidant system .


Lumbosacral radiculopathy was first described by Mixter and Barr in 1934 and since then it has been one of the most common causes of low back pain. In present study we evaluated and compared the significance of Soleus H-Reflex study and MRI of lumbosacral spine for the diagnosis of lumbosacral radiculopathy. An observational cross-sectional study was performed on 20 patients (11 females and 9 males) clinically diagnosed as lumbosacral radiculopathy at orthopaedic OPD of R. G. Kar Medical College, Kolkata. Soleus H-Reflex study was performed at the Department of Physiology and they had undergone MRI of L-S spine. All collected data were analyzed by SPSS programme. Fifty-five percent patients showed radiculopathy in their MRI while H-Reflex was abnormal in 80% patients. Out of these 80%, 40% showed unilateral absence, 35% bilateral absence and 5% decreased H amplitude. There was significant correlation between MRI and H-reflex study with a P value of 0.013. According to kappa coefficient assessment there was moderate strength of agreement between these two tests (Kappa-0.468). An interesting finding was that 5 patients out of 9 who had normal MRI; had abnormal H-Reflex result (55.56%). 80% abnormal H-Reflex results in patients of L-S radiculopathy makes it an efficient diagnostic tool. More than 55% abnormal H-Reflex in patients of clinically diagnosed radiculopathy but having normal MRI, keeps ample room for further research to find out if functional change can occur earlier before structural anomalies detected in MRI.


Freshman and sophomore college students, who have just begun their academic careers in Computer Science, are challenged by difficult courses while having little insight about the job demands in the information technology (IT) industry. This study adopts an out-of-class learning approach to discover how out-of-class learning (1) shapes students' perception of learning computer science subjects, (2) promotes understanding related to the challenges in IT professions, and (3) closes the gap between computer science education and the required IT skills in industry. The preliminary findings of this study demonstrate that interviewing IT professionals sheds light on the challenges of working in IT. Subsequently, students realize the critical skills in support of future success. This study proposes that course work in project management is a useful mechanism to bridge between the critical skills and technical skills, thereby better preparing students for careers in IT.

Errors in memory applications such as SRAM, is increased now a days due to technology scaling, higher package density and lower voltages even at normal terrestrial environments. There are several techniques to detect and correct the errors. These techniques can only detect single error and double errors due to the low encoding and decoding complexity. It leads to longer decoding time and large power consumption. In majority logic decoding technique, different set cyclic codes are used for multierror detection/correction. DSCC is a part of LDPC (Low Density Parity Check) codes. Since this technique is independent of code size.


The study program "Introduction to aviation weapon systems" was first offered in 2012 by a leading Israeli high school that is affiliated with the Israeli Air Force. This interdisciplinary program integrated physics and engineering, emphasizing the strong affinity between the two disciplines and focusing on the structure and principle of operation of weapon systems used in aviation, such as laser-based systems and thermal systems. The program was attended by twenty 12 th graders majoring in mathematics and physics who were designated to serve, upon post-graduation enlistment, in the Israeli Air Force's technological support system. The program aimed to enhance the students' interest in physics and engineering and encourage them to continue with advanced studies in these disciplines. The study described here used qualitative tools to characterize changes in students' attitudes towards physics and engineering as a result of their participation in the program. The research indicated that following the program, the students' interest in physics and engineering increased, as did their desire to continue with more advanced studies in the subject.

Calcium oxide (CaO) and calcium carbonate (CaCO3) are widely used in industry. CaO and CaCO3 can be synthesized or derived from limestone. The purpose of this study to determine the characteristics of CaO calcined limestone from Ambunten Sumenep. Lime in calcined at 850 ° C for 6 hours. Characterization of X-ray fluorescence (XRF) was conducted to determine the chemical composition of limestone, X-ray diffraction test (XRD) to find the lime crystalline phase and FTIR test to determine the absorption of wave number. XRF test results showed that the limestone chemical composition consisted of Ca of 95.37% as the dominant element, Mg of 4.1%, Fe 0.17% and Y by 0.39%. The XRD test results showed that the limestone crystal phase is ankerite (Ca [Fe, Mg] [CO3] 2) and after the calcined phase calcination is vaterite (Ca [OH] 2), calcite (CaO) and calcite (CaCO3). While the FTIR test results show that the CaO spectra are seen at 3741.24, 1417.12 and 874.14 cm -1 .


An antineoplastic agent is one of the main focuses of pharmaceutical development to treat cancer disease. In silico study can efficiently reduce the time and cost of such screening anticancer agent candidates. This study aimed to screen the biological activity and pharmacological properties of potential Cyperus rotundus bioactive compounds. Five bioactive compounds contained in Cyperus rotundus, such as apigenin, aureusidin, luteolin, quercetin, and scaberin were used in this study. The biological activity of investigated bioactive compounds was analyzed using PASS (Prediction of Activity Spectra for Substances) software. SwissADME software was used to analyze the pharmacological properties of each compound. Results showed that various biological activities have a potential as anticancer of all investigated compounds including free radical scavenging, HIF-1a inhibitor, and apoptosis agonist activity. All investigated compounds except scaberin demonstrated an antimutagenic activity, TP53 enhancer, and MMP9 inhibitor. However, antineoplastic activity only showed by aureusidin, luteolin, and scaberin. Based on SwissADME analysis known that all investigated bioactive compounds showed optimum lipophilicity, size, polarity, solubility, and flexibility. But the only scaberin showed optimum saturation. Five bioactive compounds contained in Cyperus rotundus showed a promising effect as anticancer drug candidate, so it needs to be studied further.

In early 1971, Professor Andries van Dam and his associates submitted a threefold research proposal to the National Science Foundation.


Abstract : The more familiar soluble linear differential equations are reviewed and a class of nth order differential equations with time varying coefficients is shown to be soluble by a conceptually simple transformation. This transformation is shown to be applicable in theory, if not in practice, to a class of systems - designated as uncoupled equations - which is recognizeable as a class only after transformation. In addition to this more general class of differential equations, a special class or subclass of second order linear differential equations is shown to be soluble by a different transformation and the physical implications of this transformation are discussed.

Some linear boundary value problems will be set up which contain all the essential ingredients of typical shear layer feed‐back cycles, and yet which are susceptible to exact asymptotic analysis. Models of this kind deal fully with the hydrodynamic‐acoustic coupling which is the essence of the feed‐back loop, and involve none of the usual empiricism. Specific examples will include the familiar edge tone, the two‐dimensional wall jet, and flow on one side of a plane containing a two‐dimensional slit. The latter case will be considered in detail, a phase‐locking condition will be given (leading to the well‐known integer plus one‐quarter criterion), the eigenvalue relation will be derived and its implications discussed.


Reliable predictions of long‐term ecological and evolutionary processes require more information than the periodicity of the astronomical forces that drive them.
