Endoscopy skull-base resection for ethmoid adenocarcinoma and olfactory neuroblastoma
Authors: Carta Filippo , Kania Romain , Sauvaget Elisabeth , Bresson Damien , George Bernard , Herman Philippe
Published: June 2021

Statement of problem: Olfactory neuroblastoma (ON) and ethmoid adenocarcinoma (AC) are rare sinonasal malignancies that often involve the skull base. Standard surgical treatment is craniofacial resection (CFR), which allows for efficient removal but entails significant morbidity and mortality. Because expanded endoscopy nasal approaches are newly developed, we aimed to describe the procedure in patients with ON and AC and compare it with CFR in terms of efficiency and morbidity. Methods: This work reports on a retrospective series of 16 patients with AC and ON treated endoscopically with anterior skull-base resection in a single institution over 9 years. Invasion of the frontal sinus, massive extension to the cerebral parenchyma, spread of the tumour above the orbits or lysis of anterior facial skeleton were contraindications for endoscopy resection. Results: Of the 16 patients, 11 had AC and 5 ON. In total, 37.5% (6) exhibited skull-base invasion. All patients had postoperative radiotherapy. In the early postoperative period, one patient experienced delayed seizure due to a minor subdural hematoma. Two delayed complications were observed: one encephalocele related to inappropriate postoperative care, which required revision surgery, and one extended radionecrosis. Five-year disease-free survival was 83% and 5-year recurrence-free survival 58%. Local control rate was 91% for AC and 100% for ON. Conclusions: With low perioperative morbidity and efficient local control, ethmoidectomy combined with anterior skull-base resection is a promising approach for managing selected cases of AC and ON. These findings need further investigation with prolonged follow-up.

Published: June 2021

Background: Wine experts show higher accuracy than novices in selecting a wine that matches a sample. Only one study has compared wine experts with non-trained healthy controls on smell. The aim of this study was to compare the smell characteristics, both sensorial and cognitive, of wine tasters with Spanish healthy population using the Barcelona Smell Test-24. Methods: Wine tasters were tested for smell and compared with a control group of healthy volunteers, by tasting 20 odours and scoring smell detection, identification, intensity, irritability, freshness, pleasure and forced choice. Results: Wine tasters performed significantly better on identification and forced choice than healthy controls. In addition, wine tasters perceived more odours as intense, but fewer as irritating than controls. Conclusions: Probably linked to smell education, wine tasters show better cognitive but not sensorial smell skills than a non-trained healthy population.
Investigation of the influence of ambient temperature, atmospheric pressure and water vapour pressure on epistaxis admission rate
Authors: Reddy V.M. , Judd O. , Khalil H.
Published: June 2021

Background: To investigate the relationship between weather variables (atmospheric pressure, temperature, water vapour pressure) and epistaxis admission rates at Derriford Hospital, Plymouth, United Kingdom. Methodology: Retrospective observational study using hospital inpatient information databases to identify all patients admitted with epistaxis from April 1999 to March 2009 inclusive. Meteorological data for the same period was retrieved from the University of Plymouth Meteorological Archive. Epistaxis admissions were investigated for correlation with weather variables using Pearson correlation, and stepwise multiple regression analysis was performed. Results: During the study period there were 1071 admissions (978 patients) (501 males (mean age 64 years) and 477 females (mean age 72 years)). Less than 10% of the variance in epistaxis admissions is explained by the maximum temperature only. Temperature and water vapour pressure demonstrated statistically significant association with epistaxis admission rates. Conclusions: Though there is statistical significance in the association of some weather variables and epistaxis admission rates, the findings are not practically relevant (<10% variance). The results of this study do not indicate a need for revision of current healthcare resource allocation.

Authors: Wongchai Anupong , Yi-Chia Lin
Published: June 2021

Rong Por community forest was declared to be included in the Doi Luang National Park since 1981, according to the Parliament, Act of 1961. It is the cause of conflict of interest related to government projects and possessory right of land ownership because the houses were in the Doi Luang National Park area. Moreover, the local people were accused of the invasion of forest lands from government officials cause people locals to express themselves as precedent residents the announcement of a national park clearly expressed was not invading.  Therefore, the purposes of this research aimed to study on willingness to pay for conservation of the Rong Por’s community forest and to analyze the factors affecting the willingness to pay for conservation of Rong Por’s community forest located in Dongjen Sub-District, Phukamyao District, Phayao Province, Thailand. The primary data were collected by a questionnaire, a total of 400 sample sizes. The logistic regression with Maximum Likelihood Estimation (MLE) was theoretically employed to analyze what factors affecting the values of willingness to pay. The empirical results showed that the respondents are unwilling to pay for conservation because they were confirmed that they were not intruders. Moreover, the analysis from Logistic Regression depicted that the factors affecting the willingness to pay for forest conservation are more benefits to this research and can be used as the guidelines for the policy-maker in the local area to conserve the Rong Por’s community forest.
Oxidative Coupling-Base Reaction for the Indirect Spectrophotometric Determination of Paracetamol in Drug Formulations
Authors: Thanoon Enas Samer , Raheed Lana Abdhameed , Hasan Imad Younus
Published: June 2021

A simple, rapid, and specific spectrophotometric method was developed for the determination of paracetamol  in pure form and drug formulations. The method depended on the hydrolysis of paracetamol to p-aminophenol, which, oxidized under the effect of dissolved oxygen to benzoquinoneimine. In the alkaline medium, benzoquinoneimine reacts with Methyldopa to produce a high stabile indophenol dye. The absorbance was measured at 580 nm, and the molar absorptivity was found to be 7.75 x 10-5 L/(mol cm). Paracetamol was determined in pharmaceutical products in the 10–100 μg.mL-1 concentration range with a detection limit of 1.5 μg.mL-1 PAP. The developed method can be applied to the determination of both paracetamol and p-aminophenol in the presence of each other without prior separation. The proposed method is successfully employed for the determination of paracetamol in various synthetic mixtures and pharmaceutical preparations. Our obtained results were statistically compared with those given by the similar methods and the procedures evaluated as regards to both figures of merit and ease of applicability.
Welchen Einfluss hat internationale Mobilität auf wissenschaftliche Karrieren? Ein Forschungsüberblick
Authors: Netz Nicolai
Published: June 2021

In einem systematischen Review werten Nicolai Netz, Svenja Hampel und Valeria Aman 96 empirische Studien zum Einfluss internationaler Mobilität auf wissenschaftliche Karrieren aus. Die Analyse dieses noch jungen, aber in den letzten Jahren sehr dynamischen Forschungsfeldes zeigt, dass internationale Mobilität zum Ausbau wissenschaftlicher Netzwerke beiträgt. Zudem gibt es Hinweise, dass internationale Mobilität die wissenschaftliche Produktivität und Rezeption, das heißt die Anzahl der Publikationen und Zitationen, erhöhen kann. Auch den beruflichen Aufstieg kann internationale Mobilität begünstigen. Sie scheint jedoch ebenso mit durchschnittlich längeren befristeten Beschäftigungsverhältnissen einherzugehen. Andere Karrieredimensionen – wie die Kompetenz- und Persönlichkeitsentwicklung, das wissenschaftliche Fachwissen, der Zugang zu Forschungsinfrastruktur und -finanzierung sowie Reputationsgewinne – wurden erst deutlich seltener und auf Basis weniger belastbarer Forschungsdesigns untersucht.

Тhis paper analyses the conflict-of-law regime for agency, where the main attention is given to the problem of determining applicable law for existence, extent and effects of agent’s authority (including effects of excess of authority and acting without authority), since Serbian Private International Law Act (SPILA) does not contain the special conflict-of-law rules for these issues. Having this in mind, the analysis is focused on whether the mentioned issues concerning agent’s authority should be governed by the law applicable to the internal relationship between principal and agent or by the law applicable to the contract between principal and third party, or it is necessary to create the new conflict-of-law rules for these issues in accordance with Art. 2 of SPILA that regulates filling the legal gaps. After providing the arguments against first two solutions, the author explains how to create the new conflict-of-law rules for existence, extent and effects of agent’s authority (including effects of excess of authority and acting without authority) in accordance with Art. 2 of SPILA.

Among the numerous service activities, trade services are particularly important. They belong to the group of the most important intangible and commercial services, which are provided in the function of exchange of goods. Due to their importance, trade services are subject to regulation in a number of legal acts that have been adopted so far. It can be noticed that Serbian legislation has gone through several different stages in this regard. The author provides an overview of these stages through the chronological analysis of different legislative wording of trade services and at the same time identifies the room for improvement of the current legislative framework with a particular suggestions de lege ferenda. In order to undoubtedly determine legal scope of trade services, one should keep in mind common rules setting the framework for their performance. Accordingly, these rules are classified and presented in the paper, including the consequences that arise in case of violation of these rules
Florestas Culturais: Memória e Cultura nos processos de Emergência Étnica na Amazônia, Rio Andirá, quilombo Matupiri, Barreinha-AM
Authors: Da Rocha João Marinho
Published: June 2021

Entender os processos e formas de conhecimentos criadas e acionados pelos sujeitos sociais do rio Andirá, quilombo Matupiri, Barreirinha-AM para a constituição da sua recente Identificação Étnica como quilombolas” é foco deste texto. Dialogamos com as “Questões de Identidade e Hibridismo Cultural” sugeridas a partir das leituras (HALL, 2003), (BURKE,2003) e estudos como (FUNES,1995), (GOMES,1997), (SAMPAIO,2011), quem indicam o fim do silêncio para a presença negra na configuração histórica e social da Amazônia, onde inúmeras emergências Étnicas por toda região nos últimos vinte anos. Identificar, descrever e refletir tais emergências é um dos objetivos deste texto que é um fragmento inicial da proposta de Tese junto ao Programa de Pós-Graduação em Sociedade e Cultura na Amazônia PPGSCA/UFAM. Boa Fé, Ituquara, São Pedro, Santa Tereza do Matupiri e Trindade constituem o Matupiri que, após dez anos de lutas locais e regionais articulados aos demais contextos e “agentes externos”, foi reconhecido como remanescente de quilombolas pela Fundação Cultural Palmares (Portaria Nº 176, de 24 de outubro de 2013). Nos ocupamos da compreensão desses processos de Identificação Étnica como remanescente no Rio Andirá, tradicionalmente associado como território do povo indígena Sateré-Mawé. Os sujeitos sociais do Matupiri acionaram inúmeros mecanismos para compor seu processo de constituição Identitária como remanescentes quilombolas. As festas populares aparecem como espaços simbólicos de pertencimento, onde são atualizadas as memórias do cativeiro e dos mundos vividos naquela fricção Étnica do rio Andirá que apontam para as “florestas culturais” existentes nas Amazônias. Enquanto “sujeito de direito” (MATTOS,2006), os negros do rio Andirá passaram a acionar uma memória do cativeiro que deu sustentação para sua luta por reconhecimento como comunidades remanescentes quilombolas. A memória passou então a desempenhar importante papel na construção de caminhos que os levassem ao “dizer-se e ser” (BRANDÃO, et all,2010) quilombola no Andirá. As primeiras estratégias foram marcadas pelo levantamento das reminiscências dos idosos, que passaram a ser os guardiões da memória, implicando-lhes novos valores às histórias contadas por seus pais e avós, (MATTOS,2006). Tais valores foram revestidos com a força da tradição oral os ligou a um passado da escravidão negra na Amazônia, legitimando sua luta pela titulação de suas “terras tradicionalmente ocupadas” (ALMEIDA,2008). A memória serviu no Matupiri como suporte para organizar as manifestações folclóricas que passam a ser “ritualizadas” nas comunidades em datas específicas e com isso constituem os “processos de vivências de uma memória coletiva” (ORTIZ,2006) sobre aquele grupo que se liga a experiência da escravidão do século XIX, e que, a partir de sua realidade social deste contexto do início do século XXI, busca acessar seus direitos coletivos enquanto grupo Étnico diferenciado no rio Andirá.

The Study of Dielectric Behavior and Phase Transition of Mixed Compound of Lead Tantalate Sintered with Silver Oxide with Temperature Variation
Authors:   Department of Physics, M. G. P. G. College, Gorakhpur, UP, India., Dubey Shri Prakash
Published: June 2021

The dielectric constant of mixed compound of Lead Tantalate(PbTa2O6) sintered with Silver oxide has been measured between the temperatures 40°C to 300°C using the capacitance bridge model ZENITH M 92A at the frequency of 1000 Hz. During the measurement, it is found that the properly annealed sample have three peaks at the temperature 90°C (ε = 1000), 220°C (ε =800) and 230°C (ε = 623) respectively and a high peak at the temperature of 130°C (ε = 1600) in the heating cycle curve with some intermediate fluctuations. When the variation of dielectric constant was studied in cooling cycle the peak was observed at 240ºC, above and below this temperature, dielectric constant decreases with some intermediate fluctuations showing shows a first order phase transition. The variation in heating cycle is explained on the basis of activated polarization process. When the behavior of compound is studied in cooling cycle, then pronounced hysteresis is found with certain intermediate fluctuations. The cooling cycle curve does not follow heating curve because of the temperature relaxation of the compound. The occurrence of peak at the Curie temperature is explained by the latent heat type properties of the mixed compound. The temperature variation of the mixed compound suggests for its valuable applications as active and smart materials and its applications in the ceramics.

We conducted this study by analyzing the essence of various papers on effective student management in building student achievement. Based on the results of the literature review, it is known that the role of student management in improving student achievement is seen in terms of the role of the teacher is very important, from planning to graduation or alumni, the role of student management in improving learning achievement is the involvement of regulatory efforts towards students from the time the student enters school to them. After graduating from the results of an activity that has been carried out by students, student management includes a role as one of the substances of educational management, so student management occupies a strategic position, because the central service of education, both in the setting of schooling institutions and those outside school institutions, is focused on students. School management which has an important role in the continuity of school development is student management starting from the input, process, and output of students. Student management plays a role in managing input, which is how schools and madrasah view new student admissions. The results of the discussion show that student management has a positive and significant effect on learning discipline in realizing student achievement, it can be seen from the student achievement data of the National Science Olympiad (OSN), the National Student Arts Festival and Competition (FLS2N) and the National Student Sports Olympiad (O2SN) in Wonogiri Regency Elementary School level in 2017, 2018,2019. Wonogiri Regency has actively participated in competitions in the academic and non-academic fields of students which are contested in stages. Some of the achievements have been made at the district, provincial and national levels and even have reached the international level. Educational management greatly affects the efforts to organize new students well, so that there is no overlap and time wastage in the student management process in the classroom.

Interestingly, the development of science needs, related to the ESP is most reliant on improvement every time. In the other hand, all grassroots, whether learners, teachers, educators or decision-makers; must work together to ensure the feasible continuation of the ESP education system. Moreover, science never sleeps at the heart of the empiric world; this process also takes place in the domain of the ESP. The complexity of the science realm that is intended to be (if, how, when, how, when, and what) the goal of improving the ESP in a sustainable process. Consequently, the debate on research and development must potentially lead to educational and non-educational concerns. In the field of education, it is definitely closely connected to all guiding processes in the growth of ESP research. Furthermore, the expected phase of the research and progress in the field of education must occur simultaneously unless the curriculum, which serves as the foundation for the educational process, intends to work consistently and in a measurable manner; if it is also tailored to the needs of global development. The expected needs are verbal and non-verbal communication abilities, including speaking, writing, listening and reading skills. This skill is dependent on realistic knowledge about the use of English for specific purposes. Whereas in the non-educational sphere, ESP plays a significant impacts on human development and mobilization, both intentionally and unintentionally, through individuals-in pairs-or groups: which definitely has the purpose. Essentially, however, the design process of the ESP study must be consistent with global needs in order to meet the objective of using standardized and comprehensive English in line with the position of the occasions.

The purpose of this research is to ascertain the prevalence of postoperative venous thromboembolism in the Department of Surgery at Anosiala University Hospital and to identify risk factors for developing postoperative venous thromboembolism using the Caprini Risk Assessment Model. From December 2017 to October 2019, this was a 22-month prospective cohort research conducted at Anosiala University Hospital. It included all adult patients over the age of 18 who were operated on in an emergency or on a planned basis by the Department of Surgery. This research included 662 participants. Within 30 days after surgery, the risk of venous thromboembolism was 0.3 percent. According to the overall Caprini score, 25.2 percent of patients were classified as having a low risk of venous thromboembolism, 25.2 percent as having a moderate risk, 29.5 percent as having a high risk, and 20.1 percent as having the greatest risk. Patients in the highest risk category (scoring 5) had a substantially increased chance of having venous thromboembolism after surgery (p = 0.0007). Only major open surgery was related with a statistically significant increase in postoperative venous thromboembolism (p = 0.028). Age 75 years, elective arthroplasty, and hip, pelvic, or leg fractures were not linked with postoperative venous thromboembolism statistically significantly (p> 0.05). Our findings indicate that the Caprini risk assessment model might be used successfully to avoid postoperative venous thromboembolism in surgical patients in Madagascar, since patients in the highest risk category had a considerably increased chance of developing postoperative venous thromboembolism.

This paper presents a robust signature verification and forgery detection system using Additive fuzzy and TS modeling technique. The features of various handwritten signatures are sampled with proper analysis and encapsulated to devise an effective verification system. Grid method was used to extract features angles for detection of forgeries and verification of genuine signatures. In financial Accounting, Auditing and Forensic Investigation, signature forgery could occur in various ways. This could be carried out on papers, sales documents such as invoices or inventory procurement requisition paper, title documents on landed property or other tangible assets. It is also perpetrated on payment authorization such as cheques, payment vouchers both in cash and on bills. During this exercise, the fraud perpetrators perfect their concentration on the surface paper, and trace the original signature from the mandate given earlier. It has been difficult to use accounting and auditing professions to track down financial fraud in Nigeria mostly with the problem of unearthing ingenious fraud. Exponential membership function was used to fuzzified the derived functions, and modified into structural parameters suitable to adapt to any possible variations that may result from handwriting styles and also to reflect any other factors due to scripting of a signature. The proposed system is tested on a large database of signatures obtained from 40 subjects.

This issue of supply chain management is very important for the stakeholder groups. Due to the complexity of the supply chain, its management often requires manual work and frequent sharing of information. This paper proposes a new approach that uses block chain technology to resolve the issue and improve the efficiency of the supply chain. Block chain is a distributed database that enables users to trust each other without intermediaries. Its decentralized nature and its ability to verify transactions through automated algorithms make it a safer and more secure alternative to the existing supply chain model. Due to the complexity of the coffee supply chain, the accuracy of the data collected during the CRC process became an issue. This study proposed the use of Block chain technology to address these issues.

Despite the increase in the number of female students in education indicating a reversal in the gender gap, their participation in Science, Technology, Engineering, and Mathematics (STEM) education in Malaysia is still a matter of concern. This study extends empirical explanations for this gender gap and identifies factors influencing high school students’ intentions to pursue Science, Technology, Engineering, and Mathematics (STEM) Education in Malaysia. The present study aims to develop a framework of female intention to pursue STEM education by examining the impact of five independent variables on STEM self-efficacy and in turn the impact of self-efficacy on intention. The independent variables include attitude towards STEM, self-concept, gender stereotype, motivation, and teacher stereotypes. The study also examines the independent and moderating impact of career outcome expectancy on the relationship between self-efficacy and intention. Data was collected from 211 secondary school female students in Forms 4 and 5, studying at eight secondary schools in two states in Malaysia. The data was analyzed using SmartPLS. The results of the study show that attitude, motivation, and career outcome expectancy are positive and are significant predictors of STEM self-efficacy, whereas gender and teacher stereotypes are the negative predictors. The results of the study also highlight that self-efficacy is a strong predictor of intention to pursue STEM education. These findings of the study would assist policymakers to develop suitable strategies to improve female participation in STEM education in Malaysia.

Romantic relationship dissolution (RRD) can be perceived as an upsetting or momentous event and the most stressful and unsettling events that one can encounter in life. The aim of this study to investigate the relationship between sexual involvement in a relationship and romantic relationship resolution and the role of resilience as mediators of this relationship. Two hundred ninety-three emerging young adults (ages 18 to 29) from Klang Valley have participated in this study. The present study used the Resilience Scale (RS), the Core Bereavement Items (CBI), and demographic information items. Obtained results indicated a significant difference in sexual involvement in a relationship on the level of reactions to romantic relationship dissolution. The sexual involvement in the relationship was positively and significantly correlated with romantic relationship dissolution. Specifically, sexual involvement was negatively correlated with resilience, which was, in turn, negatively associated with romantic relationship dissolution. Additionally, results also show that mediation effect for sexual involvement in resilience to romantic relationship resolution was significant. The practical implications for helping professionals were also discussed in this work.

The research studied the impact of human resource management techniques on the productivity of Nigerian deposit money institutions. The information for this research came from structured questions that were delivered to chosen deposit money institutions in Yola Metropolis. There were 193 questionnaires distributed in all, however only 166 were successfully recovered and examined. In order to estimate the effects of human resource management practice on employee productivity in the selected organization, the study used descriptive statistics and the multiple regression technique. The correlation coefficient was also used to test the extent to which human resource management is related to employee productivity. Human resource planning (HRP), recruitment and selection (RS), staff training and development (TRD), and performance appraisal (PA) were found to have a positive impact on employee productivity in the selected deposit money banks in Nigeria and were properly signed, implying that they were in line with the study's theoretical expectations. At the 5% level, the F-statistics 5.242014, which examined the combined significance of the parameter estimations, was deemed statistically significant, as evidenced by the associated probability value of 0.025272. This means that in the chosen deposit money institutions in Nigeria, all of the model's variables were jointly and statistically significant in determining employee productivity. Finally, this study found that human resource management practices in Nigerian deposit money institutions had a favorable and substantial impact on employee productivity

The API-led business model is a new way of thinking about how to engage with partners and customers through APIs. The traditional approaches were designed for business use cases having limited endpoints and speed of delivery is not critical. Traditional approaches include P2P and E2E. To overcome these drawbacks, a new approach of API-led connectivity is used. The primary aim of API-led connectivity is to allow the integration flows to be reused by means of many events and to be reused within the integration platform. This paper focuses on creating an API- led network which is agile, reusable, and fits business requirements. This network will be built for the health care system using Allscripts and Fitbit APIs. To implement API -led networks in this paper MuleSoft platform is used and API is built using the API development cycle. Depending on the business requirements on the search for API and connector already present on Anypoint App exchange. Using available component flow is created to connect EHR system systems and different devices like Fitbit. Both API are protected with OAuth 2.0 which is handled with a separate flow for initiating the communication between the system and source API. After doing the required transformation to data fetch from source API data is pushed to the Salesforce object. Using different services provided by Mulesoft, an API-led network was built in which EHR and the Fitbit device were integrated. As this development process followed agile behavior it helped in meeting business requirements for building networks. The data was successfully fetched, processed, and transferred from the EHR system and the Fitbit device to the Salesforce object.

Autonomous Vehicles (AV) reduces human intervention by perceiving the vehicle’s location with respect to the environment. In this regard, utilization of multiple sensors corresponding to various features of environment perception yields not only detection but also enables tracking and classification of the object leading to high security and reliability. Therefore, we propose to deploy hybrid multi-sensors such as Radar, LiDAR, and camera sensors. However, the data acquired with these hybrid sensors overlaps with the wide viewing angles of the individual sensors, and hence convolutional neural network and Kalman Filter (KF) based data fusion framework was implemented with a goal to facilitate a robust object detection system to avoid collisions inroads. The complete system tested over 1000 road scenarios for real-time environment perception showed that our hardware and software configurations outperformed numerous other conventional systems. Hence, this system could potentially find its application in object detection, tracking, and classification in a real-time environment.
