Flexural Band Gaps and Vibration Control of a Periodic Railway Track
Authors: Iqbal Mohd , Kumar Anil , Jaya Mahesh Murugan , Bursi Oreste Salvatore
Published: March 2021

Periodic structures exhibit unique band gap characteristics by virtue of which they behave as vibro-acoustic filters thereby allowing only waves within a certain frequency range to pass through. In this paper, both lateral and vertical flexural wave propagation and vibration control of a periodic railway track are studied in depth. More precisely, a rail fastened on rigid sleeper blocks is modeled with an Euler-Bernoulli beam. The dispersion relations in both lateral and vertical directions are obtained using the Floquet-Bloch theorem and the resulting dispersion curves are verified using finite element (FE) models. Afterwards, tuned mass dampers (TMDs) with different mass ratios are designed to control vibrations of the examined rail along both lateral and vertical directions. Moreover, the influence of damping of rail and resonators on band structures is investigated. As a replacement to the conventional TMD, a novel possibility to control vibrations relies on using another rail as a lateral distributed resonator (LDR). Although the effectiveness of LDR is lower than that of localized resonators, the former represents a simple and promising way to control vibrations. Efficacy of the proposed control methods is finally verified using the results of transient simulation based on a random Gaussian white noise input.

We determine the relationships between single nucleotide polymorphisms (SNPs), including rs5498 and rs287432 on Intercellular adhesion molecule 1 gene (ICAM1) and atherosclerotic cardiovascular disease (ASCVD) susceptibility in patients with hypercholesterolemia (HCL). The clinical characteristics of 278 participants were assessed, classified to group having HCL and without HCL. ICAM1 SNPs Genotyping was performed by DNA sequencing and ICAM1 expression was measured using real-time PCR. Positive dominant model rs5498 subjects had twice the risk of HCL (P = 0.005). Participants with the rs5498 AG or GG variants and high ICAM1 mRNA expression (≥ 3.12) had 2.68 times the risk (P = 0.000), and those with a high LDL-C concentration (≥ 3.36 mmol/L) had 1.99 times the risk (P = 0.014) of developing ASCVD compared with those with low ICAM1 mRNA and LDL-C levels. Interestingly, participants carrying the rs5498 AG or GG variants who had tachycardia (resting heart rates (RHRs) > 100 beats/min) had a 5.40-times higher risk than those with a lower RHR (P = 0.010). It may consider the G allele in ICAM1 rs5498 is associated with a higher risk of ASCVD in Thai people with HCL, and is also positively associated with ICAM1 mRNA expression, LDL-C concentration, and RHR.

Published: March 2021

Background

Currently, the postoperative prognosis of early-stage gastric cancer (GC) is difficult to accurately predict. Therefore, this study aimed to combine the basic data, clinical indicators, and treatment information of patients to establish a predictive model for early-stage GC based on a new scoring system.
Methods

A total of 3647 patients with early stage GC from the Surveillance, Epidemiology, and End Results (SEER) database were included in this study. A Kaplan-Meier survival analysis was used to compare differences in prognosis between different marital status, as an innovative prognostic indicator. Univariate and multivariate analyses were used to screen available prediction factors and then build a nomogram using the Cox proportional hazard regression model. Calibration curves and C-index were used to verify the prediction model.
Results

The univariate analysis showed that age at diagnosis, sex, histology, stage_T and N GCs, surgery in the primary site, lymph node dissection, chemotherapy, radiation, tumor size, and marital status were significant prognostic factors of GC. The multivariate analysis revealed that age at diagnosis, sex, histology, stage_T, surgery, tumor size, and marital status were independent prognostic factors of overall survival. Both the C-index and calibration curves confirmed that the nomogram had a great predictive effect on patient prognosis in training and testing sets.
Conclusion

We established an accurate prediction model for the postoperative prognosis of patients with early-stage GC based on various clinical indicators and treatment information. This nomogram can effectively help patients with early-stage GC in the future.

Published: March 2021

BackgroundWithin the sub-Saharan African region, there is a growing concern for sexual and reproductive health and rights communication, and more particularly, for adolescents. Given the existing barriers associated with face-to-face access, the need to use digital media to access information and services has become desirable and imperative, especially so due to the COVID-19 pandemic. However, in sub-Saharan Africa, a synthesis of evidence that informs adolescents’ digital media engagements for sexual and reproductive health and rights (SRHR) communication is limited. This systematic review therefore aims to examine and synthesize evidence on use of digital media for sexual and reproductive health and rights communication by adolescents in sub-Saharan Africa. MethodsA search for peer reviewed articles will be conducted in PubMed, ScienceDirect, Scopus, EMBASE, Web of Science, PsychINFO and Google Scholar with emphasis on those published between 2000 and 2020. Only observational and qualitative studies will be included. Quality assessment of included articles will be done using standardized checklists from the Joanna Briggs Institute. Both descriptive and narrative summaries will be used to appraise evidence from included studies.DiscussionThis review will be essential in providing information on the types of digital media adolescents use; the various SRHR issues they use this platform to address; their reasons for using it and associated challenges. It will also contribute to the advocacy for the inclusion of these technologies in the teaching and learning, provision of and access to SRHR information and services by teachers, public health providers and peer educators in the sub-region.Registration and Reporting This systematic has been registered in PROSPERO, an international prospective register of systematic reviews, with registration number, CRD42020211491. This protocol follows the PRISMA-P guidelines for reporting systematic reviews (see Additional file 1).

The aim of this study was to identify and validate a sensitive, high-throughput and cost-effective SARS-CoV-2 RT-PCR assay to be used as a surveillance and diagnostic tool for SARS-CoV-2 in a University surveillance program. We conducted a side-by-side clinical evaluation of a newly developed SARS-CoV-2 multiplex assay (EZ-SARS-CoV-2 Real-Time RT-PCR) with the commercial TaqPath COVID-19 Combo kit, which has an Emergency Use Authorization from the FDA. The EZ-SARS-CoV-2 RT-PCR incorporates two assays targeting the SARS-CoV-2 N gene, an internal control targeting the human RNase P gene, and a PCR inhibition control in a single reaction. Nasopharyngeal (NP) and anterior nares (AN) swabs were tested as individuals and pools with both assays and in the ABI 7500 Fast and the QuantStudio 5 detection platforms. The EZ-SARS-CoV-2 RT-PCR assay analytical sensitivity was 250 copies/ml or approximately 1.75 genome copy equivalents per reaction. Clinical performance of the EZ-SARS-CoV-2 assay was determined using NP and AN samples tested in other laboratories. The diagnostic sensitivity of the assay ranged between 94 and 96% across the detection platforms, and the diagnostic specificity was 94.06%. The positive predictive value was 94% and the negative predictive value ranged from 94 to 96%. Pooling five NP or AN specimens yielded 93% diagnostic sensitivity. The overall agreement between these SARS-CoV-2 RT-PCR assays was high, supported by Cohen’s kappa value of 0.93. The EZ-SARS-CoV-2 RT-PCR assay performance attributes of high sensitivity, excellent performance in AN sample matrix and in pooled upper respiratory samples support its use in a high-throughput surveillance testing program.

Background: The usefulness of preoperative lymph node metastasis diagnosis by 18F fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) in colorectal cancer management has been reported, but inadequate diagnostic accuracy precludes routine preoperative application. Therefore, the purpose of this study was to examine the factors influencing the diagnostic accuracy of lymph node metastasis by PET/CT in patients with colorectal cancer.Methods: We retrospectively identified 864 patients who underwent preoperative PET/CT and colorectal cancer resection at Shizuoka General hospital from January 2017 to December 2019. We examined factors influencing the diagnostic accuracy of PET/CT to detect lymph node metastasis generally and lymph node metastasis for each TNM stage according to the UICC-TNM 8th edition.Results: The overall sensitivity and specificity of PET/CT to detect lymph node metastasis in patients with colorectal cancer were 61.2% and 75.9%, respectively. Distant lymph node metastasis was diagnosed more accurately than regional lymph node metastasis. “T category” (T1/T2 vs. T3/T4) was an independent factor affecting the lymph node metastasis diagnostic capability among patients negative for lymph node metastasis [p<0.01; odds ratio 2.20; 95% CI 1.28-3.84], while among patients positive for lymph node metastasis, “Tumor diameter” was significantly associated with the lymph node metastasis diagnostic capability on univariate analysis [p=0.02]. The sensitivity and specificity of PET/CT for Stage I (T1/T2, N0) were 82.5% and 84.6%, respectively. For more advanced tumors, the diagnostic ability to detect lymph node metastasis decreased. Conclusions: Disease-specific factors such as T category and tumor diameter significantly impacted on LN metastasis diagnosis by PET/CT in patients with colorectal cancer. We recommended the preoperative application of PET/CT only for the diagnosis of distant lymph node metastasis.
Comparison of QSOFA score and SIRS criteria for prediction of sepsis outcome of patients with suspicion of sepsis outside the intensive care unit: A single-center retrospective study
Authors: Mosavi Maryamsadat , Mahfoozi lida
Published: March 2021

Objective:The present study aimed to determine quick Sepsis-related Organ Failure Assessment (qSOFA) in comparison with systemic inflammatory response syndrome (SIRS) in the prediction of the adverse consequences for the suspected sepsis patients outside the ICU.Results:Out of 128 patients with suspected sepsis, 87 (68%) patients were confirmed to have septicemia based on SIRS criteria. The SIRS criteria classified 68% patients as sepsis (87/128), of which 39(44.8%) had positive qSOFA score. The sensitivity and specificity ratios of qSOFA were 44.83% and 80.49%, respectively.ROC curve analysis showed that the area under ROC curve (AUC) of the pSOFA score for predicting the prognosis of sepsis patients were not significantly different. Moreover, regarding the sepsis-related mortality, the area under ROC showed that the qSOFA criteria (score ≥ 2) is suitable for predicting mortality with a sensitivity of 71% and specificity of 72%.Our findings revealed that the qSOFA score was significantly efficient in predicting mortality. However, the SIRS is more sensitive than the qSOFA score in predicting of the definite diagnosis of sepsis. Therefore, the qSOFA score may seem to be an invaluable tool for the identification of sepsis patients at the emergency department.

Published: March 2021

Background: Infertility is a medical condition when a couple fails to conceive after having regular unprotected intercourse without the use of any contraceptive, it a complex global health issue that can be primary with no previous conception or secondary with one or more previous conceptions. A number of anomalies in the reproductive track govern the state of infertility in female of reproductive age.Materials and Methods: The study was conducted on 100 secondary infertile women based on BMI groups {Normal 18-23.9 kg/m2 (N=35) and Overweight 24-27 kg/m2 (N=65)}, attending tertiary care infertility center: Lahore Institute of Fertility and Endocrinology, Hameed Latif Hospital. The present analytical cross sectional study was conducted to assess the BMI based combinatorial effect of gonadotropins with thyrotropin and ovarian reserve markers in secondary infertile women. Serum hormonal levels of TSH, LH, FSH and AMH were measured by using Roche electrochemiluminescence immunoassay (ECLIA) and AFC was recorded by transvaginal ultrasonography. The results were statistically analyzed by Spearman correlation test using XLSTAT, considered significant at p-value <0.05. Results: A total of 18% of secondary infertile women with normal BMI were found to have a lower serum TSH levels (<0.27µIU/ml) which can be characterized as hyperthyroidism as compared to overweight population. A strong significant positive correlation was found in the TSH, age and BMI, however, these factors were found to be negatively correlated with AMH and AFC. Gonadotropins level was increased with increase in TSH levels among participants with normal BMI but decreased with TSH escalation values among overweight population. Conclusion: TSH was found to be one of the most important diagnostic factors of infertility must be monitored in relation with other parameters (AMH, AFC, FSH, and LH) in order to spot instigation point, as it directly acts upon ovulation surge by controlling gonadotropins related actions on ovarian reserve. Weight should also be assessed regularly with age to minimize the infertility issues.
The Geological Heritage of Salobreña (South Spain): example of a touristic area
Authors: Martín M. Martín , Galdeano Sanz de , Aznar S. Moliner
Published: March 2021

Salobreña consist of a touristic area with a typical Andalusian white town built on a hill and crowned with a Castle from the medieval era of Moors occupation. The urban area is bordered by fields of tropical crops and fruit trees that, together with its location by the sea, confer on Salobreña a beautiful postcard. These features, as a whole, are an attraction for visitors. Although the authorities are very interested in developing the beach tourism and displaying and protecting the historical center of the town, the interest in geological heritage is negligible. So, this paper tries to expose and evaluate the sites of geologic interest recognizable in the area, so that not only tourists and visitors, but also students, are offered more attractions for their visits. 30 sites are proposed as suitable to be considered as geological heritage, organized in three accessible walking itineraries named respectively: Urban, Panoramic and Littoral georoutes. The selected sites display a great variety of geological typologies as structural geology, stratigraphy, sedimentology, geomaterials, petrology, mineralogy, geomorphology and hydrogeology-hydraulics. Avoiding subjectivity, the sites and georoutes have been classified and ranked with a numerical methodology based on recent literature. The Scientific Value (SV), Potential Educational Value (PEV), Potential Touristic Value (PTV) have been quantified by using several criteria in each case. This allows visitors and teachers to select the most suitable route according to their goals. The Degradation Risk (DR) has also been evaluated, giving key geo-conservation actions. This plan can be presented to political and technical managers from Salobreña Town. Finally, some actions are proposed for better conservation of the sites but also to contribute to education and promote cultural tourism. These actions would also favor educational activities for students of all levels in earth science subjects, but also increase economic activity and sustainable development in the area by incorporating cultural visitors.

Van Genesis tot Dierenrechten: denken over dieren doorheen de westerse geschiedenis
Authors: De Ruyver C.
Published: March 2021

De kennis van en de opvattingen over mens en dier veranderen doorheen de tijd. De zoektocht naar wat de mens typeert en verschillend maakt van dieren is van bij aanvang bepalend. In de Griekse oudheid legde Aristoteles, met zijn Scala naturæ, de basis voor een antropocentrisch denken over dieren. Het fundamentele verschil dat verondersteld wordt te bestaan tussen mens en dier is een leidend principe. De kerkvaders eigenden zich het denken van Aristoteles toe, waardoor ze het hiërarchische denken in relatie tot dieren verder verspreidden en versterkten in de westerse wereld. Dit eerste deel van het voorliggend tweeledig artikel eindigt met hoe Montaigne in de zestiende eeuw de hiërarchie van Aristoteles opnieuw in vraag stelde, terwijl Descartes enkele decennia later dieren nog voorstelde als puur mechanische constructies.

The Oriental fruit fly, Bactrocera dorsalis (Hendel) is a global pest of a wide variety fruits. Due to its importance, the sterile insect technique (SIT) has raised attention as a safe and sustainable solution to this pest. Successful SIT programs require a comprehensive understanding on the mating behavior of this species. Females of oriental fruit flies are known monandrous which implies that females only mate once with one male. This experiment aimed to confirm that female flies were able to mate more than once with the same (multiple mating) or different males (polyandry) in certain period of time. Four different experiments were conducted to test the hypothesis: receptivity a female to the same male (1) and different males (2) in a cage for 11 days; receptivity a mated female with the same male (3) and different males (4) in a cage for 14 days after the first mating. Results indicated that a part of the female oriental fruit flies was capable to mating more than once with the same or different males.

A comparative study of metal removal in ferric chloride solution has been completed. The purpose of this study is the effect of acid solution cause material removal of various types of metals such as steel, iron, aluminum and tin. Previously this plate had been prepared by determine the dimensions of the plate size, plate mass and ensuring the plate surface is flat. After that, the plates were immersed in ferric chloride solution with a solution percentage of 27% gram / ml in water for 2 hours. Metal plates had been cleaned and dried and then carried out post-immersion measurements for plate mass, plate dimensions, solution temperature and the acidity of the solution. The result of measurement show the metal plates of steel, iron, aluminum and tin have removed material with a depth of 0.350 mm; 0.550 mm; 0.5625 mm and 0.665 mm. The mass lost after immersion in ferric chloride solution was 2.2 g; 3.9 g; 3.6 g and 7.6 g. Through Faraday's Law, it has been found that the calculation of the material removal rate (MRR) is 0.140 cm3/hour; 0.252 cm3/hour; 0.667 cm3/hour and 0.659 cm3/hour. This has shown the acid solution can remove the metal surface,when the density of the metal is large, material removal rate is low. Therefore, further studies are needed to observe the presence of impurities in the plate and the surface roughness of the metal plate after immersion.
