Ground support design for dynamic loading conditions:A quantitative data-driven approach based on rockburst case studies

There are considerable challenges associated with the design of ground support for seismically-active underground mines.It is extremely difficult to establish the demand on ground support as well as the capacity of a ground support system.The resulting dynamic or impact loads caused by mining-induced seismicity are difficult to anticipate and quantify.The performance of a ground support system is defined by the load distribution and interaction between several reinforcement and surface support elements.Consequently,the design of ground support in seismically-active mines tends to evolve,or be modified based on qualitative assessments of perceived performance or response to significant seismic events or rockbursts.This research is motivated by a need to provide quantitative and data-driven design guidelines for ground support systems subjected to dynamic-loading conditions.Rockburst data were collected from three deep and seismically-active underground mines in the Sudbury basin in Canada.The constructed database comprises 209 seismic events that resulted in damage to mine excavations and ground support.These events were associated with damage at 324 locations within the three mines.The developed ground support design strategy,based on these documented case studies,identifies areas where the use of dynamic or enhanced support should be employed.The developed design methodology provides guidelines for the zoning of mine locations in which installation of enhanced support is recommended,the specifications for an optimal ground support system,and the timing or sequence of installation.

Feasibility study using simulation mode for offshore field SZ36-1

绥中36—1作为中海油主力注水生产、疏松砂岩稠油油田,提高采收率成为当前的主要技术方向。时移地震作为提高采收率的主要地球物理手段,使之成为主要的研究方向。本文阐述了我们利用已有的生产数据、油藏认识的可行研究,即利用动态及历史拟合的油藏模型,分析油藏可能时移地震响应,寻找时移地震响应在时空的分布特征。一方面可以分析在本地区应用时移地震技术的可行性;另一方面对第二次甚至第三次采集时移地震数据的时机进行分析。经过分析认为绥中36—1的时移地震响应除受到疏松储层的影响外,将受油藏脱气的影响。并认为生产10年后采集时移地震数据有相当的可行性。

Job satisfaction among Ethiopian nurses:a systematic review

Objective:Job satisfaction is a positive emotional feeling in the working environment,and it is an essential tool with which to improve patient safety,nurses’efficiency and performance,quality of care,retention and turnover of nurses,and commitment to the organization and the profession.There are few studies on job satisfaction of nurses in the country.Therefore,this review aims to estimate the pooled prevalence of job satisfaction among Ethiopian nurses using the available studies.Methods:This systematic review used the Preferred Repor ting Items for Systematic Reviews and Meta-Analyses(PRISMA)guideline to synthesize the evidence on the prevalence and associated factors of nurses’job satisfaction.Databases used for searching the included ar ticles from Pub Med,Embase,CINHAL,Google Scholar,HINARI,and Science Direct.All papers selected for inclusion were subjected to a rigorous appraisal using a standardized critical appraisal checklist(JBI checklist).STATA software(version 11)was used for the analysis,and 95%confidence intervals were calculated.The Cochrane Q test statistics and I2 tests were used to assess the heterogeneity prevailing between the studies.Finally,a random effect model was computed to estimate the pooled prevalence of nurses’job satisfaction in the country.Results:In this review,the data of 1,151 nurses were obtained from six studies.The pooled prevalence of nurses’job satisfaction was found to be 39.53%(24.52,54.53).The prevalence of job satisfaction in the Central part of Ethiopia was low:31.12%(95%CI 5.25,56.99)compared to the South-Eastern part of Ethiopia’s 48.01%(95%CI 36.51,59.52).The most common predictors identified were salary(P<0.05),the leadership of the organization(P<0.05),and training opportunities(P<0.05).Conclusions:The pooled prevalence of job satisfaction among nurses was found to be low in comparison with global data.The significant predictors for nurses’job satisfaction are based on the review findings,salary,leadership of organization,and training opportunities.

Parallel personal measurements of diesel engine exhaust and crystalline silica using dual sampling port

Diesel engine exhaust(DEE) and crystalline silica exposures occur simultaneously in the mining industry,and occupational sampling campaigns can be time-and cost-consuming. The authors evaluated a dualport system for simultaneous sampling of DEE and crystalline silica in laboratory and field conditions.Laboratory tests evaluated the operation of pumps during 8 h sampling and the intensity of the flow variation for various filter loading conditions and for different modes of operation. Field validation was performed in an underground mine. Pumps operated in constant flow or constant pressure modes.Tests in constant flow mode showed that when the flowrate increased on one side of the system, it decreased on the opposite side according to the loading intensity. Tests in constant pressure mode showed that flowrates systematically decreased when using loaded cassettes. However, the higher the backpressure setting, the lower the flow variation was. Flow variations during field tests were generally within the acceptable ±5% range. However, significant flow variations were identified in higher concentrations. A significant negative correlation was found between flowrate variation and total carbon concentration. While the majority of tests support the use of the dual-port for evaluating concomitant exposures, results highlight the possibility of filter overloading as a cause of flowrate changes.

Autumn migration of Ospreys from two distinct populations in Poland reveals partial migratory divide

Background:Long-term ringing and telemetry studies show that the Osprey(Pandion haliaetus)is a broad-front migrant following different migratory flyways,depending on the geographical location of their breeding populations.We have investigated two distinct and declining populations of Osprey in Poland,separated by only a few hundred kilometres,and hypothesised they may exhibit two different migration routes.We followed mortality causes,comparing them between migration and stationary phases of annual cycle,as well as between two distinct populations.Methods:Nineteen Ospreys,both juveniles and adults,were equipped with GPS loggers in 2017-2020 in two populations in western and eastern Poland and followed on their autumn migration.We calculated the distance they covered on the migration,number of stopover days,migration duration,daily distances covered and departure dates to compare them between age and sex classes and between the eastern and western populations.Results:Ospreys from the western and eastern populations showed a partial migratory divide.While the first migrated through a western flyway,the second followed a central flyway,resulting in crossing the Mediterranean Sea in distant passes that affected the distance covered.Annual mortality reached at least 67%in juveniles and at least 57%in adults.Conclusions:We showed that two distinct Osprey populations in Poland revealed a partial migratory divide,with one covering greater distances over sea and deserts over the central flyway.This might affect individual survival rates and contribute to a steeper decline in one of the populations.In order for this to be confirmed,more individuals still have to be followed.

Unitless Physics I: Relating the Fundamental Constants

The fundamental constants of Physics can be related via a numerical equivalence. This equivalence leads to a unitless transformation which reduces the number of fundamental constants and provides a simple relationship between E&M, gravitation and quantum mechanics. Unitless relationships in this paper are considered a representation associated with information processing internal to fundamental particles. The application of the unitless transformation (US9) to fundamental particle masses and lifetimes clearly demonstrates the applicability of this method to high energy physics.

Unitless Physics II: Internal Proton Structure US9-2

The internal structure of the proton is chaotic according to the Standard Model. This paper explores several possibilities, based on US9-1, for producing an internal structure of the proton which is orderly. The hypothesis that quantized distance determination via particle to particle communication is required for force application eliminates E & M in the proton interior enabling a structure consisting of gravitational orbits. Communication velocities much greater than the velocity of light are required to enable the fundamental particles to generate the accepted laws of physics. In order to generate increasing complexity in Nature, the Uncertainty Principle must become the Organizational Principle. The Hydrogen atom is the source of evolution.

Resistance Matrix for an Anisotropic Hall Plate with Multiple Extended Asymmetric Contacts on the Boundary

The electrical properties of magnetic sensing devices fabricated from anisotropic materials are not easily extracted. Here we present a method for determining the resistance matrix for an anisotropic device with multiple electrical contacts placed in a perpendicular magnetic field. By using the methods developed by Van der Pauw and Wasscher, the analysis for the anisotropic system is reduced to the equivalent problem for an isotropic sample, which can then be solved using methods developed previously. As a result, the method works in the case of structures with an arbitrary number of asymmetric extended contacts at large magnetic field strength. In addition to the extraction of nonisotropic resistivities, the resistance matrix can be used to analyze the Hall effect for anisotropic plates.
