A Descriptive Study to Assess the Knowledge Regarding Management of Hyperemesis Gravidarum among Post Natal Mothers at Selected Hospital in Meerut, UP
Authors: Mathew Ms. Blessy
Published: April 2023

Abstract: Introduction: Nausea and occasional vomiting are common in early pregnancy (NVP) . It affects 50%-80% of pregnant women during the first half of gestation. Hyperemesis gravidarum (HG) affects 0.3–3% of pregnant women and is a leading cause of hospitalization in early pregnancy. Hyperemesis Gravidarum (HG) is a pregnancy complication that is characterized by severe nausea, vomiting, weight loss, and possibly dehydration. Women may have some nausea or vomiting (morning sickness), particularly during the first 3 months of pregnancy. The exact cause of nausea and vomiting during pregnancy is not known fully. However, it is believed to be caused by a rapidly rising blood level of a hormone called human chorionic gonadotropin (HCG). HCG is released by the placenta. Mild morning sickness is common. Hyperemesis gravidarium is less common and more severe.

Designing an Interactive Web-Based Social Media Platform for College Students
Authors: Manur Shubham
Published: April 2023

Abstract: Effective communication is vital in any institution, particularly in universities, where students and academic personnel must work together toward academic and personal development. However, miscommunications and misunderstandings can arise due to gaps in communication between professors and students, as well as a lack of awareness of non-teaching staff. In addition, many important announcements and notices go unnoticed by students, as they are not consolidated in one location. To address these issues, we have developed a student-centered social media platform designed to foster collaborative learning and academic engagement. Our platform provides a single location for students to access important announcements, event details, program information, and more. It also offers interactive features such as discussion forums, group projects, and peer-to-peer messaging, allowing students to connect with their peers and academic personnel more easily.

Published: April 2023

Abstract: India is an agricultural country where 70% of the populations are dependent on agricultural performance. But if we see that as the population increases, the farm is spread out among families, and for that reason, the farmer in India owned on average only two acres of farms. Also economically, farmers are very poor due to which they are unable to purchase tractors and other costly equipment hence they use traditional methods of farming. Essentially, a lot of farmers in India also use oxen, horses and buffaloes for farming. This will not address the energy needs of agriculture relative to other countries in the world. So, we are thinking that the efforts of man and animal can be replaced by advanced mechanization which will be adapted to small farmers from the point of view of the economy and effort. We are therefore developing this equipment that will meet all these needs and resolve the problem of work. Index Terms – Agricultural performance, Energy needs, Advanced mechanization, small farmers, Costly equipment, Economy and Effort

Published: April 2023

Abstract: The quality of work life of women police in Chennai has been a subject of growing interested and concern in recent years. This study aims to explore the various dimensions of the quality of work life of women police officers in Chennai, including job satisfaction, work environment, work-life balance, and overall well-being. The study employs a mixed-methods approach, including surveys and interviews, to gather data from women police officers in Chennai. The results of the study suggest that women police officers in Chennai face numerous challenges in their work environment, including a lack of support from their male counterparts, limited opportunities for career advancement, and poor working conditions. Despite these challenges, the majority of women police officers in Chennai report a high level of job satisfaction and a strong commitment to their profession. Overall, the findings of this study highlight the need for greater support and resources for women police officers in Chennai, as well as for further research into the factors that contribute to their quality of work life. The present study investigated the influence of quality of work life (QWL) on career development among women police officers in Chennai, India. A total of 200 women police officers were selected as the sample for the study. The data were collected using a structured questionnaire measuring QWL and career development. The results indicated that QWL significantly predicted career development among women police officers. Specifically, work-life balance, job security, and social support were significant predictors of career development. These findings suggest that improving QWL can enhance career development among women police officers. The study provides insights into the factors that influence career development among women police officers, which can be useful for policymakers and organizations to improve their working conditions and support women's career development in the police force.

Abstract: Business and finance sector have come the leader of the world’s frugality moment. The stock request trading is one of the major practices in the finance sector. In the literature, unwanted stock data have been reused which leads to destruction of time and memory space. The vaticination of unborn stock price by SVM and Backpropagation algorithm is less effective because of processing unwanted data. In this paper, LSTM grounded recommender system for safe stock trading is proposed. The standard stock datasets similar as AMD, Google and Tesla were employed for trial of the proposed work. Further, deep literacy libraries similar as Keras API module and Tensor Flow along with python were employed for enforcing the proposed work. In the living workshop, the authors achieved the delicacy in the range of 60 to 70 and in this proposed work, the delicacy rate is bettered to 75 in prognosticating the stock. The performance of the proposed work is also compared with three stock datasets considered for comparison. The successful vaticination of the stock request will have a veritably positive impact on the stock request institutions and the investors also. It finds the accurate value of the coming day closing value that helps the investors to invest or vend their shares. In future, the work can be extended by enforcing with better dimensionality reduction ways.
Vasculitis pauciinmune asociada a lupus eritematoso sistémico: a propósito de un caso
Authors: Pedroza Pallares Alvaro , Orozco Carlos , Roa Alejandra
Published: April 2023

Introducción: la poliangeítis microscópica (PAM) hace parte del grupo de vasculitis asociadas a anticuerpos anticitoplasmáticos de neutrófilos (ANCA), cuya presencia de anticuerpos contra mieloperoxidasa (MPO) se observa en la mayoría de los casos (70-95?%), asimismo, el compromiso renal presagia mayores tasas de morbilidad y mortalidad, sin embargo, la coexistencia con lupus eritematoso sistémico (LES) es poco frecuente y con mayor énfasis en la variante de LES del adulto mayor o de inicio tardío.
Objetivo: dar a conocer un caso poco común de dos enfermedades autoinmunes, lo cual ha sido reportado como síndrome de superposición y brindar información útil que permita ampliar los diagnósticos diferenciales.
Presentación del caso: se presenta el caso de un paciente masculino de 76 años con historia de poliartralgias progresivas en deterioro del estado general, con debut en síndrome confusional agudo, caída de filtrado glomerular, microhematuria y proteinuria casi nefrótica. A la evaluación inicial se encontró anemia y trombocitopenia severa, en perfil inmune ANA 1/320 y complemento consumido, cumpliendo criterios para LES, ANCA reactivo específicamente MPO ANCA (1/320) y sospecha de glomerulonefritis con patrón rápidamente progresivo (GNRP). Dado el contexto clínico, se decidió comenzar con pulsos de metilprednisolona consecutivos, seguidos de prednisolona oral y, como terapia de mantenimiento, se instauró ciclofosfamida. Finalmente, con una biopsia renal se confirmó el diagnóstico de vasculitis sistémica pauciinmune con formación de crescencia celular. La evolución clínica del paciente fue satisfactoria, logrando la estabilización de órganos y la normalización de la función renal, hematopoyética y el estado neurológico.
Discusión y conclusión: dado que la presentación clínica de LES es heterogénea, se ha reportado su asociación con vasculitis, las cuales comparten un compromiso común de órganos como articulaciones, piel y riñones. Los hallazgos paraclínicos, como por biopsia, fueron consistentes tanto con PAM como con LES, por lo tanto, se diagnosticó como un caso de superposición. Este caso demuestra el enigma del diagnóstico y la complejidad en el manejo de entidades poco frecuentes, de etiologías inmunológicas superpuestas que ponen en peligro la vida de quien la(s) padece, de no tener un diagnóstico oportuno y un tratamiento temprano.
Quantum Regularized Least Squares
Authors: Chakraborty Shantanav , Morolia Aditya , Peduri Anurudh
Published: April 2023

Linear regression is a widely used technique to fit linear models and finds widespread applications across different areas such as machine learning and statistics. In most real-world scenarios, however, linear regression problems are often ill-posed or the underlying model suffers from overfitting, leading to erroneous or trivial solutions. This is often dealt with by adding extra constraints, known as regularization. In this paper, we use the frameworks of block-encoding and quantum singular value transformation (QSVT) to design the first quantum algorithms for quantum least squares with general ℓ2-regularization. These include regularized versions of quantum ordinary least squares, quantum weighted least squares, and quantum generalized least squares. Our quantum algorithms substantially improve upon prior results on quantum ridge regression (polynomial improvement in the condition number and an exponential improvement in accuracy), which is a particular case of our result.To this end, we assume approximate block-encodings of the underlying matrices as input and use robust QSVT algorithms for various linear algebra operations. In particular, we develop a variable-time quantum algorithm for matrix inversion using QSVT, where we use quantum eigenvalue discrimination as a subroutine instead of gapped phase estimation. This ensures that substantially fewer ancilla qubits are required for this procedure than prior results. Owing to the generality of the block-encoding framework, our algorithms are applicable to a variety of input models and can also be seen as improved and generalized versions of prior results on standard (non-regularized) quantum least squares algorithms.
State retrieval beyond Bayes' retrodiction
Authors: Surace Jacopo , Scandi Matteo
Published: April 2023

In the context of irreversible dynamics, associating to a physical process its intuitive reverse can result to be a quite ambiguous task. It is a standard choice to define the reverse process using Bayes' theorem, but, in general, this choice is not optimal. In this work we explore whether it is possible to characterise an optimal reverse map building from the concept of state retrieval maps. In doing so, we propose a set of principles that state retrieval maps should satisfy. We find out that the Bayes inspired reverse is just one case in a whole class of possible choices, which can be optimised to give a map retrieving the initial state more precisely than the Bayes rule. Our analysis has the advantage of naturally extending to the quantum regime. In fact, we find a class of reverse transformations containing the Petz recovery map as a particular case, corroborating its interpretation as quantum analogue of the Bayes retrieval. Finally, we present numerical evidences that by adding a single extra axiom one can isolate the usual reverse process derived from Bayes' theorem.

O fenômeno de extravasamento de muco, também referido como mucocele, é uma lesão comum da mucosa oral resultante da ruptura de um ducto da glândula salivar com extravasamento da mucina. O principal fator etiológico é o trauma local. A localização mais comum é o lábio inferior, mas outros locais podem ser afetados. Existe a necessidade de diagnóstico diferencial uma vez que, pelo aspecto clínico e localização, as mucoceles assemelham-se a outras lesões que afetam a boca. Diante desse cenário, o objetivo deste trabalho foi relatar dois casos clínicos de fenômeno de extravasamento de muco (mucocele), evidenciando suas características clínicas, histopatológicas, tratamento e prognóstico. Acredita-se que o conhecimento das principais características dessa condição patológica possa auxiliar o clínico na adoção dos principais procedimentos na avaliação, conduta e tratamento desses pacientes.

A candidíase oral trata-se de uma infecção fúngica e tem como cepa predominante a Candida albicans. Este fungo é encontrado em diferentes membranas mucosas do organismo humano e quando ocorre um desequilíbrio da microbiota local, manifestam-se múltiplas lesões que podem evoluir para quadros clínicos severos. Apresenta elevada frequência em pacientes imunossuprimidos e sob uso prolongado de antibióticos e corticosteroides, e o seu tratamento padrão se baseia na utilização de compostos azóis e poliênicos. Contudo, devido à possível citoxicidade desses medicamentos associada à resistência dos microrganismos, há uma crescente busca por terapias alternativas, o que inclui o uso de fitoterápicos. O presente estudo objetivou apresentar a utilização do óleo essencial de melaleuca ou Tea Tree Oil (TTO) no manejo de infecções fúngicas em cavidade oral. A metodologia se baseou na busca inicial de artigos nas bases eletrônicas: National Library of Medicine (PubMed), Biblioteca Virtual em Saúde (BVS) e literatura cinzenta do Google Scholar, utilizando-se  o  cruzamento  dos  descritores DeCS/MeSH  “melaleuca oil” AND “oral thrush”. De forma a complementar a fundamentação teórica, utilizou-se sites institucionais, além da livre busca através das referências inicalmente selecionadas. Um total de 20 trabalhos foram incluídos e os resultados demonstraram efeito satisfatório do óleo de TTO na prevenção e no tratamento da candidíase oral em cepas de Candida albicans através de estudos experimentais em modelo animal.

Semiconductor photocatalysts have great potential in solving environmental problems. The photocatalyst process using a semiconductor is one of the technology to oxidize organic compounds such as dyes. Orange peel (KJ) is one of the adsorbents that have the potential for purification of dyes that increase the photocatalytic activity of ZnO material. This study aims to determine the optimum variation of KJ-CTAB to be added to ZnO material. The results of the synthesis of ZnO/KJ-CTAB varasis 1:25, 2:25, and 3:25 (w/v) using the wet impregnation method were characterized on IR, XRD, SEM, DR-UV, and BET instruments. The results showed that FTIR also showed the presence of ZnO bonds in all samples, C-H in samples varied from 1:25, 2:25, and 3:25 (w/v). The XRD results showed that the percentage of crystallinity decreased and the SEM results showed that ZnO/KJ-CTAB 1:25 had a more homogeneous morphology. Based on the results of DR-UV ZnO/KJ-CTAB 1: 25 (w/v) has a band gap energy value of 3.20 eV which is good for use in photocatalyst processes. BET results show that all samples belong to the mesoporous size.

Information and Communication Technologies (ICT) have transformed practically all sectors of society due to the benefits that these tools bring with them. The education sector has been one of the ones that has had the greatest impact with these digital transformation processes and it is required that teachers and students improve their levels of digital literacy. However, it has been identified that there are different ways to carry out the process of measuring digital literacy, but a literary review on this topic has not been constructed. Based on the above, this article reviews the literature and bibliometric analysis on the measurement and evaluation of digital literacy. For this, a systematic search of bibliographic material was carried out in the Web of Science database and an analysis was carried out using the Biblioshiny tool. The results of this process show that, although this topic has been discussed since 2004, only until 2012 was relevant research carried out on the measurement of digital literacy, likewise, it was possible to identify that what is sought is to measure the skills and competencies of teachers and students for the use and exploitation of ICT. In practical terms, this document is expected to enable people interested in digital literacy measurement and evaluation to identify relevant areas and locate their own research.

Authors: Mariastella Messina
Published: April 2023

Project portfolio management is a strategic weapon. Despite, the abundant amount of literature on research and development (R&D) project evaluation and selection, earlier research does not exploit the potential of learning even if it may generate significant opportunities. The aim of this paper is to deepen the knowledge on how a learning process could favor the selection and management of projects to include in the portfolio, considering the relevance of strategic orientation. Grounded on learning the concept of pragmatic constructivism (PC), this paper presents a qualitative and interpretative approach conducted in a single case study. The selected company is a multinational, operating in the semiconductor industry. Data were collected by combining different sources such as semi-structured interviews, direct observation, meeting participation and use of archival sources. The results show that the role played by previous learning can provide very useful information for division managers in the company to pick up the best project to include in the portfolio, which meet business strategic priorities. The results provide some practical implications in supporting the decision-making process of division managers on how to choose the best project portfolio, meaning to pick up the right projects to increase the performance of the project portfolio as well as company performance.
On Equivalence of State Based Potential Games
Authors: Wang Jinhuan , Wu Han
Published: April 2023

By the method of semi-tensor product of matrices, state based potential
games are investigated. Firstly, using the potential equation, a
necessary and sufficient condition and a sufficient condition are
proposed, respectively, to verify whether a state based game is
potential. Then two static equivalence conditions of state based
potential games are presented. Furthermore, the dynamic equivalence is
given such that the state based games dynamically equivalent to the
state based potential games have similar dynamic properties. Lastly, the
concept of state based networked evolutionary games is proposed. A
necessary and sufficient condition is given to assure a state based
networked evolutionary game is potential.
