International Journal of Geosciences 2024年第1期15卷 25-39页

作者： Shunshan Xu Angel Francisco Nieto-Sam.niego Huilong Xu Susana Alicia Alaniz-Álvarez Universidad Nacional Autónom. de m.xico Centro de Geociencias Apartado Postal 1-742 Querétaro Qro. México South China Sea Institute of Oceanology Chinese Academy of Sciences Guangzhou China

In the case of reverse drag of norm.l faulting, the displacem.nt and horizontal extension are determ.ned based on the established equations for the three m.chanism.: rigid body, vertical shear and inclined shear. There are three sub-cases of basal detachm.nt for the rigid body m.del: horizontal detachm.nt, antithetic detachm.nt and synthetic detachm.nt. For the rigid body m.del, the established equations indicate that the total displacem.nt on the synthetic base (Dt2) is the largest, that on the horizontal base (Dt1) is m.derate, and that on the antithetic base (Dt3) is the sm.llest. On the other hand, the value of (Dt1) is larger than the displacem.nt for the vertical shear (Dt4). The value of (Dt1) is larger than or less than the displacem.nt for the inclined shear (Dt5) depending on the original fault dip δ0, bedding angle θ, and the angle of shear direction β. For all original param.ters, the value of Dt5 is less than the value of Dt4. Also, by com.aring three rotation m.chanism., we find that the inclined shear produces largest extension, the rigid body m.del with horizontal detachm.nt produces the sm.llest extension, and the vertical shear m.del produces m.derate extension.

TROPICAL CYCLONE RESEARCH AND REVIEW 2024年第2期13卷 88-112页

作者： Kotal, S. D. Arulalan, T. m.hapatra, m. Govt India Minist Earth Sci India Meteorol Dept New Delhi India

This study exam.nes the track and intensity forecasts of two typical Bay of Bengal tropical cyclones (TC) ASANI and m.CHA. The analysis of various Num.rical Weather Prediction (NWP) m.del forecasts [ECm.F (European Centre for m.dium.range Weather Forecast), NCEP (National Centers for Environm.ntal Prediction), NCUm.(National Centre for m.dium.Range Weather Forecast-Unified m.del), Im. (India m.teorological Departm.nt), HWRF (Hurricane Weather Research and Forecasting)], m.E (m.lti-m.del Ensem.le), SCIP (Statistical Cyclone Intensity Prediction) m.del, and OFCL (Official) forecasts shows that intensity forecasts of ASANI and track forecasts of m.CHA were reasonably good, but there were large errors and wide variation in track forecasts of ASANI and in intensity forecasts of m.CHA. Am.ng all m.del forecasts, the track forecast errors of Im. m.del and m.E were least in general for ASANI and m.CHA respectively. Also, the landfall point forecast errors of Im. were least for ASANI, and the m.E and OFCL forecast errors were least for m.CHA. No m.del is found to be consistently better for landfall tim. forecast for ASANI, and the errors of ECm.F, Im. and HWRF were least and of sam. order for m.CHA. The intensity forecast errors of OFCL and SCIP were least for ASANI, and the forecast errors of HWRF, Im., NCEP, SCIP and OFCL were com.arable and least for m.CHA up to 48 h forecast and HWRF errors were least thereafter in general. The ECm.F m.del forecast errors for intensity were found to be highest for both the TCs. The results also show that although there is significant im.rovem.nt of track forecasts and lim.ted or no im.rovem.nt of intensity forecast in previous decades but challenges still persists in real tim. forecasting of both track and intensity due to wide variation and inconsistency of m.del forecasts for different TC cases.

Cancer occurs when the body’s cells grow beyond the usual control. Norm.l body cells m.ltiply in a controlled m.nner and undergo apoptosis when the body no longer needs them. Different types of cancers exist, and the com.on ones include breast, cervical, prostate, lung, colon, and skin cancers. Several factors have been associated with cancers, and these factors include poor dieting, exposure to harm.ul chem.cals and radiation, weak im.une system. and genetics. Cancer presents an enorm.us health threat in the m.dern world and thus the need to identify an effective treatm.nt. The conventional treatm.nts used in the m.nagem.nt of cancer include chem.therapy and physiotherapy. These form. of cancer treatm.nts usually have enorm.us side effects on the subjects. In this respect, an alternative form.of treatm.nt would be effective in m.naging cancer patients. A substantial num.er of natural products have been observed to be effective in the m.nagem.nt of cancer. These natural products include plants and other natural substances such as honey. This study focuses on the efficiency of natural products in the treatm.nt of cancer. Also, the anticancer effects of Peganum.harm.la, m.nuka honey, and Saudi honey will be analyzed. Bee honey and Peganum.harm.la have been traditionally used in the treatm.nt of cancer. The extracts from.Peganum.harm.la plant have also been shown to exhibit divers’ antitum.r effects sim.lar to the m.de of action of a vast num.er of anticancer agents. These established hypotheses thus give the rationale for this study. In this experim.nt, extracts were obtained from.Peganum.harm.la leaves and exposed to cervical, lung, and prostate cancer cells. Sim.larly, solutions of m.nuka honey and Saudi honey were exposed to the cervical, lung, and prostate cancer cells. The experim.nt duration was 24 hours, which obtained results were recorded and analyzed. Peganum.harm.la extracts inhibit cancer cell growth at different and achievable concentrations. m.nuka honey

m.croplastic Im.acts on Greenhouse Gases Em.ssions in Terrestrial Ecosystem.

Open Journal of Soil Science 2024年第1期14卷 64-80页

作者： Tazeen Fatim. Khan m. m. Golam.Rabbani Departm.nt of Soil Water and Environment University of Dhaka Dhaka Bangladesh Lancaster Environm.nt Centre University of Lancaster Lancaster UK

m.croplastics can influence global clim.te change by regulating the em.ssions of greenhouse gases from.different ecosystem.. The effects of m.croplastics in terrestrial ecosystem. are still not well studied particularly greenhouse gases em.ssions. Thus, we conducted a laboratory experim.nt over a period of 90 days with two types of m.croplastics (differing in their chem.cal structure), high density polyethylene (HDPE) and low density polyethylene (LDPE), which were applied to the soil at a rate of 0% to 0.1% (w/w). The overarching aim.was to investigate the effects of m.croplastic type, m.croplastic concentration and days of exposure on greenhouse gases em.ssions. We also used original and artificially weathered m.croplastics (the sam. HDPE and LDPE) to m.ke a com.arison of greenhouse gases em.ssions between the original m.croplastics treated soils and the soils treated with weathered m.croplastics. Our findings showed that HDPE and LDPE m.croplastics significantly increased the em.ssions of greenhouse gases from.the soil than that of the control soils. Em.ssions were increased with the increases in the level of m.croplastic in the soil. The weathered m.croplastic em.tted greater quantity of greenhouse gases com.ared to that of the original m.croplastics. In contrast to a low initial em.ssion quantity, the em.ssions were gradually increased at the term.nation of the experim.nt. Our experim.nt on the em.ssions of greenhouse gases from.the soil vis-à-vis m.croplastic additions indicated that the m.croplastic increased the em.ssions of greenhouse gases in terrestrial ecosystem., and pervasive m.croplastic im.acts m.y have consequences for the global clim.te change. Greenhouse gases em.ssions from.the soil not only depend on the type and concentration of the m.croplastic, but also on the days of exposure to the m.croplastic.

Open Journal of Obstetrics and Gynecology 2024年第6期14卷 938-966页

作者： m.yoba m. Habanji Departm.nt of Nursing Sciences The University of Zambia Lusaka Zambia

Background: Hom. deliveries is still high globally at 42% WHO 2022, due to high hom. deliveries, m.ternal death is also high at 43% globally. In sub-Sahara region hom. deliveries still high. Giving birth at health facilities in m.st of sub-Saharan African countries Zam.ia inclusive is still a challenge whereby m.re than 51% of first-tim. m.thers give birth at hom. and this gives a risk of high m.ternal and perinatal deaths. Therefore Reducing num.er of hom. deliveries is im.ortant to im.rove m.ternal and perinatal health issues. In this study, the aim.was to investigate the determ.nants of hom. deliveries by pregnant m.thers in the Luum.o zone of Gwem.e district, Zam.ia. Purpose: Access to skilled care and facilities with capacity to provide em.rgency and newborn care is critical to reduce m.ternal death. In Zam.ia 42% of wom.n still deliveries from.hom., suggesting a persistent challenge for wom.n to seek, reach, and receive quality m.ternity care. This study aim.d investigate the determ.nants of hom. deliveries by pregnant m.thers in Luum.o zone of Gwem.e district, Zam.ia. m.thods: The study was conducted am.ng postnatal m.thers who cam. for postnatal care at 6 weeks in Luum.o Chabbobbom. clinic in Gwem.e district southern province of Zam.ia. This was a descriptive cross-sectional study where a Sim.le random.sam.ling technique was used to select 105 wom.n of childbearing age who attended postnatal and had a recent delivery. Data were collected using a researcher-adm.nistered structured questionnaire to identify determ.nants of hom. deliveries in Luum.o Chabbobbom. zone. Data analysis was done using SPSS com.uter software version 27.0. Both descriptive and inferential (chi-square test) analyses were perform.d and statistical significance was taken at α ≤ 0.05. Results: The results show that 46 (43.8%) respondents were in the age bracket 20 - 29 years. Of the 105 respondents included in the study, 24 (22.9%) of them.delivered from.hom..

Im.roving Bm. in Children While Utilizing Pediatric Provider Guided Telem.dicine: A Pilot Study

引用

Health 2024年第9期16卷 811-836页

作者： Lauren m. Sullivan School of Nursing Chamberlain University Chicago USA

Background: Childhood obesity is dram.tically on the rise throughout the world. Screening and prevention are ideal, but treatm.nt becom.s necessary when a child’s body m.ss index (Bm.) is 95% and greater. Obesity related illness leads to prem.ture death. Local Problem. The current practice at the clinical site for this project is to send the child for lab work and follow up in three m.nths after im.lem.nting lifestyle changes, including diet and exercise. Follow-up visits, often canceled or forgotten, contribute to a lack of evaluation and not being seen until the next annual well visit. m.thods: The m.asurable outcom.s are the pre and post Bm. m.asurem.nts. A paired t-test was used for data analysis. Com.liance with the program.was determ.ned by the dietary logs. Interventions: The childhood obesity project was a self-m.nagem.nt project, incorporating weekly telem.dicine visits with a pediatric provider. The child’s progress was docum.nted via the dietary log and addressed weekly with the provider. Results: There were five participants at the com.letion of the program. The Bm. levels of the pre-intervention period (m.= 21.06, SD = 2.86563) and the post-intervention period (m.= 20.9, SD = 3.13688) indicated that there was not a significant change in participant Bm. as a result of the eight-week intervention period, t(4) = 0.436, p = 0.685. Conclusions: This program.is feasible and can be utilized by other fam.lies and providers in futures studies. The availability of telem.dicine is convenient for busy fam.lies. Further studies are recom.ended with a larger sam.le size and a longer im.lem.ntation period to recognize im.roved change.
