Authors: Abdelmohsen Ahmed S. , Ahmed Zeinab N. , Hasanain Ahmad F. , Abozaid Mohamed A.A. , Hassan Waleed A.
Published: June 2023

Background

Upper gastrointestinal bleeding (UGIB) is a common gastrointestinal emergency with significant morbidity and mortality. Intravenous (IV) route administration of proton pump inhibitors is more commonly used for prevention of bleeding; however, it is more expensive and invasive than the oral route. We, herein, compared between oral and IV omeprazole in patients with high-risk UGIB regarding outcome.

Patients and methods

Patients with high risk for rebleeding peptic ulcers were included. All patients initially received IV omeprazole, and then esophagogastroduodenoscopy with hemostatic procedure was done. Thereafter, the patients were allocated to group A, who received oral omeprazole, and group B, who received IV omeprazole. The patients were followed up for 2 weeks for signs of rebleeding. Reendoscopy, angioembolization, or surgery was provided when needed (NCT04170270).

Results

The study included 189 patients (96 in group A and 93 in group B). Frequency of rebleeding was higher among patients in group B (40%) compared with those in group A (30%) (P: 0.1). Reendoscopy was more frequently required for patients in group B (16.1%) than those in group A (3.1%) (P<0.001). Surgery was mandatory for three (3.2%) patients in group B, whereas angioembolization was used nearly equally in both groups (31.3% in group A vs. 29% in group B). Admission to ICU was more frequently needed (P: 0.02) and the length of hospital stays was longer (P: 0.003) for patients of group B. Regarding UGIB-related deaths, three (3.1%) patients from each group died.

Conclusion

Oral omeprazole is not inferior to IV omeprazole as adjuvant therapy to control peptic ulcer bleeding and to reduce the frequency of rebleeding.
Single parent adoption in India
Authors: Ranjan R , Nath S , Jha S , Narasimha VL
Published: June 2023

Single parent adoption (SPA) is a relatively new construct worldwide and in India. The Ministry of Women and Child Development, Government of India, has laid down criteria for adoption in general and SPA in particular, in conjunction with the Juvenile Justice Act (Care and Protection of Children), 2015. There is scant literature on this topic of SPA, more so in India, that looks into the various psychological nuances of SPA from a mental health professional's (MHP) perspective. This review paper aims to assess SPA from the perspective of a MHP that will focus on its various legal nuances as well as the psychological connotations attached to it. For this, a search strategy was employed that included a thorough literature search from two databases (PubMed and Google Scholar) with relevant keywords related to the topic. The various legal issues pertaining to SPA in the current scenario, the psychological issues and challenges faced by single parents, the behavioral outcomes of adoptees who are adopted by single parents, and ways to deal with the various obstacles of SPA are discussed.
Low degree of patient involvement in contemporary surgical research: A scoping review
Authors: Mojadeddi ZM , Öberg S , Rosenberg J
Published: June 2023

Background:

Patient and public involvement in research was introduced a few decades ago. However, there is still a lack of knowledge of the degree of patient involvement, particularly in surgical research. The aim of this review was to characterize the use of patient/public involvement in contemporary surgical research and to describe how patients were involved, if they gained authorships, and which countries studies came from.

Methods:

In this scoping review, original studies and reviews about surgery were included that had patient/public involvement regarding study planning, conducting the study, and/or revising the manuscript. Screening was performed in the issues from 2021 of five general medicine journals with high-impact factors, also classically called “the big five,” and in the ten surgical journals with the highest impact factor.

Results:

Of the 808 studies, 12 studies from three journals had patient involvement, corresponding to 1.7%. Patients were involved as participants in nine of the studies either in the designing of the study and/or in revising or approving the protocol; and in four studies in revising and/or approving the manuscript. One patient fulfilled the ICMJE authorship criteria and received a group authorship. Studies with patient involvement originated from six countries namely, Australia, Canada, Netherlands, Norway, USA, and UK; with five studies from the UK.

Conclusion:

Patient involvement is very low in contemporary surgical research. It is primarily in the study planning phase, authorship is almost non-existent and few countries publish such studies.
Behçet's disease-induced massive small intestinal bleeding successfully treated with adalimumab
Authors: Liu PH , Tsai TH , Yeo KJ , Chou JW
Published: June 2023

We herein report a case of Behçet's disease in a 27-year-old female who suffered from generalized skin rashes for one week. After hospitalization, massive bloody stools accompanying hypovolemic shock occurred. Emergency abdominal computed tomography-angiography failed to detect the bleeding source. Esophagogastroduodenoscopy also demonstrated no definite bleeding points. Ileocolonoscopy showed multiple large and deep ulcers with some blood coating and mild oozing in the terminal ileum. We initially performed epinephrine injection and hemoclips for her intestinal bleeding. However, massive bloody stools still continued. Thus, we prescribed a loading dose of 160 mg adalimumab followed by weekly 80 mg adalimumab subcutaneous injections to the patient. Following this treatment, her gastrointestinal bleeding gradually subsided and completely stopped within a few days. After three-week therapy with adalimumab, capsule endoscopy showed several healing ulcers without bleeding in the distal to the terminal ileum. She continues to be treated with adalimumab, azathioprine, and mesalazine without recurrent bleeding.

Authors: Bamaiyi Adamu Jibril , Madaki Habib Ozavinoyi , Musa Hamis Muhammad , Usman Abdulrasheed , Zagga Muawiya Usman , Tambuwal Bello Umar , Umar Hayatu
Published: June 2023

Context:

Hypertension is an important cause of the cardiovascular disease (CVD). Blood pressure (BP) elevations and the associated complications are influenced by age.

Aim:

To evaluate age-related variations in systolic BP, diastolic BP, and the derived pulse pressure (PP), mean arterial pressure (MAP), as well as pulse rate (PR) in a community sample of adults in Sokoto.

Settings and Design:

Adult individuals, predominantly non-hypertensive, non-diabetic that attended a free medical screening in a Sokoto community, Northwestern Nigeria were evaluated.

Materials and Methods:

Blood pressure, anthropometry, and random blood glucose were measured.

Statistical Analysis Used:

Database storage and analysis were carried out using IBM SPSS, version 23.0.

Results:

Systolic BP correlates with age increases beyond other BP parameters (standardized β-coefficient of systolic BP = 0.4071, R2 = 0.0933, Diastolic BP = 0.1485, R2 = 0.0409, PP = 0.2587, R2 = 0.0661, MAP = 0.2347, R2 = 0.0757, PR = -0.0087, R2 = 0.0001). The same trend was observed when age-dependent variations in the BP parameters were assessed independent of body weights (Fcrit = 2.398, F = 151.911, df = 4, P = 0.000) and independent of the steady state pressure, MAP (Fcrit = 2.637, F = 795.975, P = 0.000). However, when the population is considered by age categories of ≤50 years or >50 years separately, diastolic BP rather than the systolic BP better explain the relationship in the ≤50 years category.

Conclusion:

Although all the components of BP should be monitored when treating hypertension in adults, systolic BP and its derivative PP be given more attention.

Authors: Habib Abdullahi A. , Abba Usman , Abdullahi Hauwa M. , Ibrahim Sa'idu Adamu
Published: June 2023

Context:

Thyroid hormones play a key role in the menstrual and reproductive functions of women. Thyroid dysfunction is marked by a large number of menstrual aberrations.

Objective:

To determine the incidence of thyroid dysfunction in dysfunctional uterine bleeding (DUB) and its correlation with menstrual patterns.

Materials and Methods:

The study population consisted of 64 DUB patients aged between 19 and 45 years and an equal number of age-matched women with a normal menstrual cycle. Plasma concentrations of thyroid-stimulating hormone (TSH), free thyroxine (T4), and free triiodothyronine (T3) of the participants were measured. Laboratory analyses were conducted on Elecsys 2010 immunology analyzer. Statistical analysis was performed with Microsoft Excel software, and the data were transferred into IBM SPSS version 21.0 for processing. A P-value of <0.05 was considered significant.

Results:

Among the 64 women with DUB, 21.9% had thyroid dysfunction, of which 14.1% had overt hypothyroidism, 6.2% had subclinical hypothyroidism, and 1.5% had overt hyperthyroidism. The main menstrual complaint among hypothyroid DUB patients was menorrhagia. The only presentation in hyperthyroidism was oligomenorrhea.

Conclusion:

The prevalence of abnormal thyroid function in this study was high; therefore, screening of DUB patients for thyroid function abnormalities is suggested.

Published: June 2023

Context:

The cost of in-patient care for common non-communicable diseases is enormous, considering the health financing options in most developing countries. With the general economic down-turn in the country, and the predominant out-of-pocket payment for health service method by patients in our resource challenged settings, these patients usually incur catastrophic health expenditures. However, with the recent adoption of the contributory health schemes by some state governments to reduce the out-of-pocket payment by poorly remunerated citizens, studies on the cost of illness are imperative to enhance effective provider planning and administration.

Aim:

To estimate the cost of illness associated with managing acute stroke in Kano.

Setting and Design:

We conducted a cross-sectional study where eighty five adults with established diagnosis of stroke were enrolled using a cost of illness questionnaire. Prevalence-based costs were stratified by patients' socio-demographic characteristics and socio-economic scores (SES). The “bottomup” and “human capital” approaches were used to generate estimates of the direct and indirect costs, respectively. All estimates of the financial burden of the stroke were analyzed from the patients' perspective using Statistical Product and Services Solutions (IBM SPSS V.22).

Results:

A total of 85 patients participated in the study (AKTH-45, MMSH-40). Most were within the middle-age group (69.4%), had the ischemic stroke subtype (82.4%) and belong to the low socio-economic class (41.2%). The total costs of care for the 85 patients amounted to N8,753,623.00 ($21,339.37). The cost of illness for accessing care by a stroke patient was N102,983.80 ($251.05). The direct cost accounted for N72,730.00 ($177.40), and the indirect cost was N30,252.90 ($73.75). The projected economic burden of acute stroke care by adult population in Kano was also enormous. The health facility of care, stroke subtype, and length of hospital-stay accounted for the significant difference in cost of illness between the study patients (P < 0.001).

Conclusions:

Cost of illness in managing acute stroke care was found to be high, and with the sizeable proportion of the population belonging to the low socio-economic class, cost-effective primary preventive strategies to reduce risks for stroke is imperative.

Authors: Isah Ahmed Rufai , Aliyu Usman Malami , Adenipekun Adeniyi , Cambell Oladapo Babatunde , Ango Umar Mohammad
Published: June 2023

Context:

Nasopharyngeal cancers were initially thought to be an uncommon disease in Nigeria, but recent studies have shown a steady increase in the incidence of the disease with an associated increase in morbidity and mortality due to late presentation.

Aims:

The aims are to evaluate the mode of presentation and referral pattern of nasopharyngeal cancer patients seen.

Settings and Design:

This was a retrospective review of patients with nasopharyngeal cancer seen in the department of Radiation Oncology U.C.H. Ibadan from 2000 to 2009.

Methods and Material:

Patients' biodata, clinical–pathologic presentation, and site of referral were retrieved using data extraction form and subsequently analyzed using Microsoft Excel (2013).

Statistical Analysis Used:

It is a descriptive analysis.

Results:

A total of 205 patients with histologically confirmed nasopharyngeal cancer seen during the study period were analyzed. The mean age of the patients was 41.7 years with 144 (70.2%) males and 61 (29.8%) females. The commonest presenting complaint was cervical lymphadenopathy in 98.5% of patients followed by nasal blockade, nasal discharge, and epistaxis with 82.0%, 78.0%, and 51.2%, respectively. Undifferentiated carcinoma was the commonest histologic type (68.8%). Majority of patients were civil servants (33.2%). The habit of smoking and alcohol ingestion was unspecified in majority of patients (43.4%). Ingestion of smoked fish has been found in majority of patients (122, 59.5%) with the disease in this study. Most of the patients came from southern part of the country which coincides with the geographic distribution of Burkitt's lymphoma; hence, the possibility of Epstein–Barr virus as one of the likely causative agents. None of the patients presented with stage I disease, while most patients presented at stage III 129 (62.9%).

Conclusions:

Nasopharyngeal cancer is common. Cervical lymphadenopathy, nasal blockade with undifferentiated histology, and late presentation were the norm. Referrals were from all the regions of the country.
Age-related variation in lifestyle and its relationship to chronic disease as shown by a survey using a self-evaluation questionnaire
Authors: Thakral Sonika , Garg Rahul , Bijlani Ramesh
Published: June 2023

Background:

Many of the prevalent diseases have their roots in inappropriate lifestyle besides heredity. Modifiable lifestyle factors may be effective in the prevention and management of such diseases, as indicated by several research studies. This cross-sectional survey explores the correlation between various lifestyle factors and some common diseases primarily in the Indian context.

Materials and Methods:

A lifestyle questionnaire having 40 questions and comprising 7 dimensions was administered as a Google Form. The subjects of the study, recruited using convenience sampling, were all above 17 years of age.

Results:

The subjects were divided into four age groups. The lifestyle score (LS) increased with age, with the maximum rise happening in the age group 31–40. For the age groups 31–40 and 41–60, significant differences were found in the LSs of those having a lifestyle disease and those having none; two out of seven dimensions could predict the presence of a lifestyle disease for these groups. A dimension-wise comparison between Indian and outside India subjects within age groups revealed that Indians scored better in most cases where there was a significant difference. A similar comparison between males and females showed that females scored better in all cases of significant difference. However, females had a significantly more incidence of lifestyle diseases.

Conclusions:

The impact of a low LS starts becoming visible in the age group 31–40. Furthermore, this group makes maximum efforts to improve lifestyle. Hence, it is likely to be benefited the most by health education. Since females appear to be more prone, they need special focus.

Authors: Malhotra Varun , Sampath Ananyan , Javed Danish , Bharshankar Rajay , Mishra Shweta , Singh Vijender , Gautham Namita
Published: June 2023

Introduction:

The aging process and the pandemic have significantly affected the elderly population, resulting in a wide range of physiological and psychological changes. These changes have created a significant burden for the nation as the elderly is often overlooked. In response to this, the Government of India and AIIMS Bhopal developed a yoga-meditation-based intervention to help improve the mental health of the elderly (>60 years) during the pandemic.

Methodology:

A retrospective case − control study was conducted on the geriatric population aged over 60 years of both sexes from March 2021 to September 2021 at the All India Institute of Medical Sciences, Bhopal. The sample size was calculated to be 690 participants based on the prevalence of depression and anxiety in the elderly population and using the depression, anxiety, and stress scale 21 (DASS)-21. Participants were asked to fill out the DASS questionnaire, and those with mild to moderate depression, anxiety, or stress were randomly divided into two groups. The intervention group received a 6-week yoga-based mobile intervention, and the results were analyzed using the SPSS software version 27.

Results:

The between group analysis showed that MOMMY intervention was effective in reducing symptoms of depression (t=3.38, df=93, p<0.001), anxiety (t=4.33, df=93, P < 0.001) and stress (t = 1.76, df=93, P < 0.05).

Conclusion:

Lockdowns caused by the COVID-19 pandemic had a significant impact on the psychological status of individuals. The study found a significant reduction in depression, anxiety, and stress levels after the intervention, indicating the necessity of similar interventions on the geriatric population to alleviate their mental health status.

Published: June 2023

Introduction:

Research evidence and theoretical models point to the need to implement yoga and mindfulness interventions as they impact different physiological and psychological functioning associated with addiction and relapse. To ensure the safe application of yoga, a standardized yoga module that can be practiced across any drug type of substance addiction is required. This study focuses on developing, validating, and testing a yoga module’s feasibility for the management of substance use disorder (SUD).

Materials and Methods:

The yoga module was developed for SUD by including specific yogic practices derived from research evidence from Google Scholar, PubMed, and traditional literature targeting symptoms related to SUD. Yoga experts validated the module using a 3-point Likert scale. Practices which scored a content validity ratio (CVR) score ≥0.33 were retained in the yoga module for SUD. A pilot assessment was done online to test the module’s feasibility. Participants in a 9-week residential rehabilitation center participated in the study. The module was taught as an add-on to their existing treatment. The motivation for seeking treatment was assessed at baseline, and quality of life was assessed at pre- and post-intervention using the questionnaire de motivation au traitement des toxicomanies and the World Health Organization Quality of Life BREF (WHOQOL BREF), respectively.

Results:

Thirty experts validated the developed module. Based on the CVR scoring, 37 yoga practices were retained. The final list of practices included breathing exercises, sukshmāvyāyāma (loosening exercise), āsana (postures), prāṇāyāma (breathing exercise), and dhyāna (meditation). In the feasibility study, all participants (n = 12) reported satisfaction and mentioned no adverse effects of the yoga intervention. The participants’ mean ± standard deviation (SD) of identified motivation was 26.6 ± 1.9, introjected amotivation 22.7 ± 5.1, external motivation 16.4 ± 6.2, and a motivation 15.1 ± 5.7. The Global score or Internalization coefficient mean ± SD was 29.1 ± 18.1. The participant’s total score on the WHOQOL-BREF was significant post intervention (P = 0.004). With the practice of the module, there was a significant change in the participant’s psychological (P = 0.008), social (P = 0.002), and environmental domains (P < 0.001) but not in physical health (P = 0.17). At 1 month follow-up, 11 participants (n = 12) maintained abstinence.

Conclusion:

The designed yoga module for SUD was validated by yoga experts and was considered safe and feasible by patients with SUD. In addition, patients reported an increase in their quality of life. This can be further studied in randomized controlled trials.
Analogy between contemporary underlying factors in teaching with Taittiriya Upanishad
Authors: Baghel Richa
Published: June 2023

The purpose is to understand the values of Indian education and its contemporary implication. Peace, teaching, pedagogy, perception and values, memory and knowledge recitation, and convocation are categorized as essentials of teaching in the Taittiriya Upanishad. These are essential to enhance the creativity of a learner and implement knowledge. The objective of this study is to explore the relevance of ancient Indian education in the current time. A mixed and multiple-stage method was employed, comprising a literature review, pilot studies, and an empirical survey questionnaire adopted in this research. After learners contemplate the teachings, they find a unique way to implement their wisdom. The Indian education values discuss self-exploration. Relationships between teacher–student, their psychology, family, and society are the context of the Guru–Shishya tradition. It shows the relevance of Traditional Indian Education in contemporary times and matches the objectives of the New Education Policy 2020, India. The need of the hour is education patterns and rethinking knowledge delivery. Today the Internet is a hub of information; however, information is transcended by a teacher. All 30 variables of the study are still relevant in contemporary times out of 32 variables given in the Taittiriya Upanishad.

Authors: Sangeethalaxmi M. J. , Hankey Alex
Published: June 2023

Background:

Bronchial asthma afflicts many millions of people worldwide, with multinational studies finding over 4% of young adults on asthma medication. Prescribed medication may alleviate symptoms but does not cure. The complementary system of yoga therapy has developed yoga practice modules that improve symptoms, but are cumbersome, and lead to high dropout rates.

Results:

We report the development of a new, shorter yoga module that achieved zero dropouts over a 90-day randomized controlled trial.

Discussion:

All yoga breathing exercises could be done standing or sitting in a chair, making the module suitable not just for young adults, but for all ages.

Published: June 2023

Pranayama is one of the most essential components of yoga which has been found to be effective to physiology of the mankind in many ways. Among the Pranayamas, Bhastrika Pranayama is one of the popular breathing techniques widely practiced in yoga, which is believed to improve pulmonary, cardiac, and psychological functions. This present systematic review was planned to explore the available scientific studies on Bhastrika Pranayama individually on pulmonary, cardiovascular, and psychological variables. PubMed, Scopus, EMBASE, Cochrane Library, and Google Scholar were the basis for our review of the literature. The final review included 19 trials on Bhastrika Pranayama between 2005 and 2021 based on eligibility criteria, including four randomized controlled trials and another 15 clinically controlled trials. The quality assessment of each individual trial was performed using the Jadad Scale and the assessment showed ten trails as high quality studies (score 4–8) and nine trials as low quality studies (score 0–3). The results were discussed based on ten high-quality trials and the findings showed that Bhastrika Pranayama significantly improves pulmonary, cardiovascular, and psychological variables, although there were some limitations related to sample size, study quality, follow-up duration, and practice guidelines. Future studies should address those limitations to reach better conclusions.

Published: June 2023

Phy-X/PSD and XCOM are two software programs used for computations in radiation shielding and nuclear energy research. This study aims to compare the accuracy of Phy-X/PSD with that of XCOM in the determination of mass attenuation coefficient (MAC) of glass systems. The MAC values of 60B2O3-(40-x)BaO-xBi2O3, 50BaO-xBi2O3-(50-x)borosilicate glasses, and xTeO2-(70-x)ZnF2-25AsO3-5Sm2O3 glass systems at 0.662 MeV, 1.172 MeV and 1.332 MeV were determined using Phy-X/PSD. The mean absolute error (MAE) was determined and compared with MAE from experimental data and from XCOM. The results showed no significant difference between the MAC means obtained from the three data sets. However, single factor ANOVA test shows that the p-values for the MAC means are 0.344, 0.918 and 0.239 approximated to 3 d.p at 0.662 MeV, 1.172 MeV, and 1.332 MeV respectively and the variance was highest in the experimental result, followed by Phy-X/PSD, and least in the XCOM results. It could be concluded that both software programs can be used for radiation shielding computations, although result from Phy-X/PSD may have relatively more outliers compared to XCOM.

Digitalization of Higher Education in 2021 – Challenges for University Students In Russia
Authors: Kalugina Tatiana N. , Timchenko Maria V.
Published: June 2023

Digital educational platforms emerged as an anticipated technological response to the need for the modernization of higher education. The digitalization of education was promoted at the state level as a strategy and an instrument to improve the quality and competitiveness of education. In 2020, the coronavirus pandemic accelerated the transition from the classroom to online-only, revealing the lack of purposeful online teaching methods, and insufficient digital competence among teachers.

The authors analyzed publications by foreign and Russian researchers to highlight the common problems of higher education digitalization, including datafication, limited capabilities of digital educational platforms, and the changing role of the teachers in e-learning. The article focuses on students’ attitudes towards online education, and their voluntary or unwilling involvement in the digital educational environment, considering synchronous, asynchronous, and blended forms of learning before and during the pandemic.

The achieved results suggest that such factors as the novelty and accessibility of online courses at Western universities initially served as a factor of attraction the students, inviting them to diversify their studies in their own creative way. However, increased stress and workload, various technical problems, tough teachers’ control on the one hand, and poor feedback, on the other, weakened the popularity of the digital educational environment. When asked to compare the pros and cons of online education, most students spoke in favour of maintaining the blended education format, as it allows for reducing the workload and – to some extent – enables the students to take control of their education trajectories.

This work is intended for educators and researchers interested in the challenges caused by integrating digital technologies into traditional forms of education.
KADA RODA NEĆE DA SLETI: PSIHOLOŠKI ASPEKTI NEPLODNOSTI
Authors: Mitrović Milica , Opsenica Kostić Jelena , Jestrović Enser Jovana
Published: June 2023

Neplodnost predstavlja ozbiljan problem savremenog čoveka koji osim pojedinca i para, pogađa i društvo u celini. Može se reći da je neplodnost globalni bio-psiho-socijalni problem, sa trendom porasta. Ozbiljnost i učestalost ovog problema ilustruje činjenica da Svetska zdravstvena organizacija (World health organisation – WHO) rangira neplodnost kao peti najveći uzročnik invaliditeta među svetskom populacijom mlađom od šezdeset godina. Svi statistički pokazatelji učestalosti neplodnosti različitih organizacija (WHO, UCLA Health, CDC, United Nations Population Fund)1 su u najmanju ruku zabrinjavajući. Uzroci neplodnosti su brojni, od čega najveći procenat pripada medicinskim uzrocima. Međutim, porast stope neplodnosti u najvećoj meri se dovodi u vezu sa odlaganjem roditeljstva i zasnivanjem porodice u poznijim godinama. Većina izveštaja o prosečnoj starosti žena na području Evrope i Amerike u trenutku rađanja prvog deteta pokazuje trend porasta i iznosi oko dvadeset devet godina (EUROSTAT, National Center for Family & Marriage Research, The Human Fertility Database). Ova pojava se dovodi u vezu sa značajnim demografskim i društvenim promenama poslednjih godina dvadesetog veka, koje su značajno izmenile stil života muškaraca i žena. Obrazovanje postaje dostupnije ženama, one ulaze na tržište rada, postaju finansijski samostalne, angažuju se na radnim pozicijama koje su do početka ovog veka isključivo bile dodeljivane muškarcima. Veća kvalifikovanost i radna kompetentnost žena uz dostupnost kontracepcije vode ka odlaganju roditeljstva, a samim tim i do povećanja reproduktivne disfunkcije povezane sa starenjem kod muškaraca i žena.
A SURVEY ON MOBILITY-AWARE AND DELAY-SENSITIVE SERVICE PROVISIONING IN MOBILE EDGE-CLOUD NETWORKS
Authors: R.Thamarai selvi  , Ms.E.Padma
Published: June 2023

Mobile edge computing (MEC) has emerged as a viable technique for pushing the cloud frontier to the network edge, enabling network services to be provisioned in close proximity to mobile consumers. Serving customers at the edge of the cloud can minimize service latency, lower operational costs, and increase network resource availability. Along with MEC, network function virtualization (NFV) is a viable strategy for implementing various network service functions as software in cloudlets (servers or clusters of servers). Giving mobile consumers virtualized network services can improve their service experience, simplify network service deployment, and make network resource management easier. However, mobile users roam arbitrarily inside networks, and different users often request various services with varying resource needs and latency requirements. As a result, it is a significant issue to provide dependable and smooth virtualized network services for mobile users in a MEC network while satisfying their specific latency needs, subject to network resource limits. This research focuses on the supply of virtualized network function services for mobile users in MEC while taking user mobility and service latency requirements into mind. We begin by posing two novel optimization issues for user service request admissions, with the goals of maximizing accumulative network utility and accumulative network throughput over a certain time horizon. Then, for the utility maximization issue, we design a constant approximation approach. We also create an online method for the problem of accumulative throughput maximization. Finally, we use experimental simulations to assess the performance of the suggested methods. The results of the experiments show that the proposed algorithms are promising.

Application of Time-Frequency Decomposition and Seismic Attributes for Stratigraphic Interpretation of Thin Reservoirs in Onshore Fuba Field Niger-Delta, Nigeria
Authors: U. Ochoma
Published: June 2023

Application of time-frequency decomposition and seismic attributes for stratigraphic interpretation of thin reservoirs in Onshore Fuba Field Niger Delta, Nigeria, are here presented, using Well-log and 3D Seismic data. Well-to-seismic tie, fault mapping, horizon mapping, time surface generation, depth conversion and seismic attributes generation were carried out using Petrel software. Structural interpretation of seismic data reveals a highly faulted field. Two distinct horizons were mapped. Fault and horizon interpretation shows closures that are collapsed crestal structures bounded by two major faults. All the interpreted faults are normal synthetic and antithetic faults which are common in the Niger Delta basin. The depth structure maps reveal anticlinal faults. Reservoirs are found at a shallower depth from 6500 to 7500 ft and at a deeper depth ranging from 11500 to 13000 ft. The variance and chaos values range from 0.0 to 1.0. The Variance edge and chaos analysis were used to delineate the prominent and subtle faults in the area while the produced spectra were used to delineate the stratigraphy and thickness of the thin-bedded reservoirs. The results of spectral decomposition at frequencies between 12Hz and 35Hz indicate some thin pay sand zones reservoirs which were characterized by of low frequency and high amplitude associated with known hydrocarbon zones, meandering channels, lobes and the presence of small scale faults in the field. Six new probable zones (Prospects A, B, C, D, E and F) of hydrocarbon accumulation were identified. The results of the study will help in the recovery of more hydrocarbon as by-passed zones and subtle structures are revealed in the area of study.

Soil Fertility mapping are helps in reducing the cost of fertilizer and environmental risks. In KRP Dam catchment, 92 surface soil samples collected from major paddy-growing soils were used for soil fertility mapping in a GIS environment. Soil properties viz, pH ranged from highly acidic to strongly alkaline, with the maximum area being slightly alkaline (19.98%) and moderately alkaline (26.16%), -1 but soils were non-saline (<2 dSm ). Organic carbon (OC) varied from low (<0.5%) to high (>0.75%) occupied 20.01% and 44.90%, respectively. The soils were high (>-1 22 kg ha ) in available phosphorus (P), occupying 42.55% area followed by low P in 19.35% area and medium P in 18.72% area. There soils were medium to high in available potassium (K) and available sulphur (S). DTPA-Cu was found to be above the critical limit, but deficient in iron, manganese, zinc and boron. The extent and distribution of soil nutrients will help in site-specific fertilizer recommendations for paddy farming in the KRPdam catchment.

Accounting vs. Politics: Effects of China-US Audit Cooperation on China Concept Stocks
Authors: Wang Shijie
Published: June 2023

Abstract

Since 1993, Chinese companies have entered the US capital market, becoming a crucial platform for their public listing and fundraising. However, inconsistent accounting policies between China and the US have resulted in the delisting of certain China Concepts Stocks (CCS) in the US. Nonetheless, the recent accounting review cooperation agreement between the China Securities Regulatory Commission and the US PCAOB has altered the future prospects of CCS in the US. This study aims to quantify the economic value of this bilateral collaboration using the Audit Supervision Cooperation Agreement, signed by China and the US on August 26, 2022, as a natural experiment. Our findings reveal that in the three months following the agreement, CCS with political connections and accounting issues related to the Chinese government exhibited returns of 4.63% and 1.13% respectively. We conducted robustness tests including parallel trend tests, experimental and control groups based on VIE architecture interference, and sub analysis samples and placebo tests. Additionally, trading volume and price volatility of politically affiliated companies also experienced positive effects. In conclusion, our study underscores the significant impact of the political friendship between China and the US on the economic development of both nations and the global economy.

Uma corrida de skyrmions em nanopistas ferromagnéticas
Authors:   , Araújo Alane Silva
Published: June 2023

O modelo de Heisenberg bidimensional apresenta soluções topológicas do tipo skyrmion. A forma destas estruturas é altamente afetada pelas condições de contorno. Os skyrmions usuais possuem um núcleo e carga topológica inteira Q. Porém, de acordo com uma condição de contorno específica, o skyrmion pode apresentar dois núcleos, sendo formado por duas estruturas chamadas meron e antimeron, cujas cargas individuais são dadas por 𝑄 𝑞 = . Quando colocadas para se moverem sob a ação de correntes spin-polarizadas, estas estruturas sofrem a ação da força de Magnus, que as impelem numa direção perpendicular à corrente de spin, fenômeno conhecido por efeito Hall de skyrmion. Ao se movem ao longo de uma nanofita magnética, os skyrmions serão destruídos ao atingirem a borda da nanopista. Neste trabalho, com o uso de simulações micromagnéticas, foi estudado o movimento de skyrmions estabilizadas em nanopistas ferromagnéticas. Analisamos diferentes tipos de estruturas de skyrmions, sendo elas, as estruturas residentes em materiais contendo a interação Dzyaloshinskii-Moriya (IDM-skyrmion), skyrmions contendo um núcleo (skyrmion do tipo I) e skyrmions contendo dois núcleos alinhados horizontalmente (h-bimeron) e verticalmente (v-bimeron). Foi comparado o movimento destes ao longo da pista de corrida, desconsiderando a interação skyrmion-borda, e feita uma análise em relação a sensibilidade de cada estrutura distinta à ação da força de Magnus. Foram utilizados modelos analíticos a fim de explicar os resultados obtidos através das simulações. Como resultado, pode-se concluir que pequenas deformações na forma da estrutura do tipo h-bimeron alteram consideravelmente a sua massa, desviando significativamente a sua trajetória em relação a trajetória das outras estruturas estudadas. Foi observado também que o IDM-skyrmion é a estrutura mais sensível ao efeito Hall de skyrmion comparada com as outras analisadas. Palavras-chave: Modelo de Heisenberg. Skyrmions. Bimeron. Efeito Hall de Skyrmion.
