The Enforcement of Occupational Safety and Health Requirements in Public and Private Sectors in the Emirate of Abu Dhabi, the United Arab Emirates

Research Problem: In Abu Dhabi, limited implementation of OSH Regulations contributes to the general unawareness among employees and workers about occupational hazards and safety measures, resulting in slow responsiveness toward enforcement measures and a lack of self-regulatory approaches within companies. Purpose: The purpose of this study is to examine the implementation methods practised in Abu Dhabi with those in developed countries with established OSH regulatory bodies. Methodology: Qualitative and quantitative research methods were employed to gather primary research data. Workers from various industries in Abu Dhabi were sampled on purpose and asked to respond to questionnaires and interviews on OSH protocol awareness and implementation, and circumstances of workplace incidence. Results: The findings of this study showed that the enforcement of OSH requirements in UAE positively correlated to a reduction in the rate of work-related injury and improved business performance. The quantitative research data showed that the energy sector had the highest score (15) while the tourism sector had the lowest score (5.3) in occupational health systems and improvements in business efficiency and productivity. Implications: The outcomes of this study shed light on the importance of implementing OSH Guidelines for companies to empower their safety managers to fully enforce OSH requirements in their organisations. In conclusion, effective OSH enforcement requires cooperation between general workers and OSH managers and facilitation from business owners.

Availability of basic life support courses for the general populations in India, Nigeria and the United Kingdom: An internet-based analysis

BACKGROUND:The number of lay people willing to attempt cardiopulmonary resuscitation(CPR)in real life is increased by effective education in basic life support(BLS).However,little is known about access of general public to BLS training across the globe.This study aimed to investigate availability and key features of BLS courses proposed for lay people in India,Nigeria and the United Kingdom(UK).METHODS:A Google search was done in December 2018,using English keywords relevant for community resuscitation training.Ongoing courses addressing BLS and suitable for any adult layperson were included in the analysis.On-site training courses were limited to those provided within the country's territory.RESULTS:A total of 53,29 and 208 eligible courses were found for India,Nigeria and the UK,respectively.In the UK,the number of courses per 10 million population(31.5)is 79 and 21 times higher than that in India(0.4)and Nigeria(1.5).Course geography is limited to 28%states and one union territory in India,30%states and the Federal Capital Territory in Nigeria.In the UK,the training is offered in all constituent countries,with the highest prevalence in England.Courses are predominantly classroom-based,highly variable in duration,group size and instructors'qualifications.For India and Nigeria,mean cost of participation is exceeding the monthly minimum wage.CONCLUSION:In contrast to the UK,the availability and accessibility of BLS courses are critically limited in India and Nigeria,necessitating immediate interventions to optimize community CPR training and improve bystander CPR rates.

Collapse-type shrinkage characteristics in plantation-grown eucalypts： I . Correlations of basic density and some structural indices with shrinkage and collapse properties

Collapse-type shrinkage is one of highly refractory drying defects inlow-medium density plantation-grown eucalypt wood used as solid wood products. Basic density (BD),microfibril angle (MFA), double fibre cell wall thickness (DWT), proportion of ray parenchyma (RP),unit cell wall shrinkage, total shrinkage and residual collapse, which are associated withcollapse-type shrinkage characteristics, were investigated by using simple regression method forthree species of collapse-susceptible Eucalyptus urophyll,, E. grandis and E. urophyllaxE.grandis,planted at Dong-Men Forest Farm in Guangxi autonomous region, China. The results indicated that:unit cell wall shrinkage had a extremely strong positive correlation with BD, moderately strongpositive correlation with DWT, and a weakly or moderately negative correlation with RP and MFA;total shrinkage was positively correlated with BD, DWT and RP and negatively related to MFA, but notable to be predicted ideally by any examined factors alone owing to lower R^2 value (R^2≤0.5712);residual collapse was negatively correlated with BD and DWT, linearly positively correlated withMFA, and had strongly positive linear correlation with RP. It is concluded that BD can be used assingle factor (R^2≥ 0.9412) to predicate unit cell wall shrinkage and RP is the relatively soundindicator for predicting residual collapse

A Study on Water Demand Load Estimation by Using Unit of Living Water - Focused on Micro Water Supply Area in Daegu City

Water supply capability has been significantly reduced as water demand has been increased due to changes of the world's weather, causing the increase of drought frequency, and urbanization. In terms of water production, water can be secured by construction a dam or procuring substitute water. However, the study approaches in terms of management of water supply area to control the existing water efficiently. Therefore, water demand was estimated by buildings, by which water load of micro water supply area was calculated. As a result, the deviation of water demand for 1,357 micro water supply areas could be calculated while the alternatives to dissolve the spatial demand unbalance were suggested by two types. From the study, firstly, we could anticipate the total water supply demand from the total sum by filtration plants but it was not possible to anticipate the characteristics of distribution within urban areas. For this, the study attempted to anticipate the demand of each 250 thousands of buildings, comprehending the demand of micro areas. Secondly, based on the built results, we suggest the directions to dissolve the water demand unbalance between and among regions, which could be the foundation to suggest the concrete methodology in the future.

Optical transmission through basic-structural-unit superlattices

In this paper, by the transparent-component-decimation （TCD） method we obtain three kinds of new basic- components （BCs） through simplifying and decomposing the BCs of three-component Thue-Morse （3CTM） sequence. Based on these new BCs we propose a type of basic-structural-units （BSUs） and investigate the optical transmission of the one-dimensional （1D） superlattices composed of these BSUs. It is found that if the substrates of the 1D BSU superlattices are certain, the optical transmission at the central wavelength （CW） will be determined completely by the number and the type of BSUs and has nothing to do with the marshalling sequence. In particular, if the substrates are identical, the numbers of different types of BSUs are all the same and the middle two elements of BSUs constitute a cycle, then no matter whether the system is periodic, or quasiperiodic, or aperiodic, or unordered, or even random, it will be transparent at the CW. The conclusion is confirmed by the numerical results. Similar to the even layers of neighbourhood identical elements in TCD method, such a kind of optical BSU subsystem can also be decimated from the chain in the process of transmission investigation. There would be a potential application in the designing of some interesting optical devices.

AIM To provide suggestions for hand injury prevention by study the demography and risk factors of casualties suffering from isolated hand injuries.METHODS All trauma patients with isolated hand injuries who were admitted to Al Ain Hospital for more than 24 h during a period of 3 years were studied. Patient demographics,location, mechanism/time of injury, and length of hospital stay were all analyzed.RESULTS Two hundred and ten patients were studied. Their mean age was 29.7 years. Males constituted 92%. Sixty-five point one percent of all cases were from the Indian subcontinent. The workplace was the most common location of injury(67.1%), followed by the home(17.1%)and road(6.2%). Machinery caused 36.2% of all injuries,followed by heavy object(20.5%) and fall(11%). Cases injured at home were young(P < 0.0001) with an associated higher incidence of females(P < 0.0001).CONCLUSION Male workers in Al Ain city are at greater risk of sustaining hand injuries, predominantly from machinery. Safety education, personal protection, and the enforcement of safety standards are essential to the prevention and avoidance of hand injury.

Occupational exposures and colorectal cancers:A quantitative overview of epidemiological evidence

A traditional belief widespread across the biomedical community was that dietary habits and genetic predisposition were the basic factors causing colorectal cancer.In more recent times,however,a growing evidence has shown that other determinants can be very important in increasing(or reducing) incidence of this malignancy.The hypothesis that environmental and occupational risk factors are associated with colorectal cancer is gaining ground,and high risks of colorectal cancer have been reported among workers in some industrial branches.The aim of this study was to investigate the epidemiologic relationship between colorectal cancer and occupational exposures to several industrial activities,by means of a scientific literature review and meta-analysis.This work pointed out increased risks of colorectal cancer for labourers occupied in industries with a wide use of chemical compounds,such as leather(RR = 1.70,95%CI:1.24-2.34),basic metals(RR = 1.32,95%CI:1.07-1.65),plastic and rubber manufacturing(RR = 1.30,95%CI:0.98-1.71 and RR = 1.27,95%CI:0.92-1.76,respectively),besides workers in the sector of repair and installation of machinery exposed to asbestos(RR = 1.40,95%CI:1.07-1.84).Based on our results,the estimated crude excess risk fraction attributable to occupational exposure ranged from about 11% to about 15%.However,homogeneous pattern of association between colorectal cancer and industrial branches did not emerge from this review.

Growth Habit of the Basic Oxysulfate Magnesium Whisker

The growth habit of the basic magnesium oxysulfate whisker was investigated based on the theoreticalmodelof anion coordination polyhedron growth units.It is found that typicalbasic magnesium oxysulfate whisker growth is consistent with anion tetrahedralcoordination incorporation rules.The growth units of basic magnesium oxysulfate whiskers are [Mg-（OH）_4]^（2-） and HSO_4^-.[Mg-（OH）_4]^（2-） is the favorable growth unit and whisker growth is in the direction of the [Mg-（OH）_4]^（2-） combination.A plurality of [Mg-（OH）_4]^（2-） s combine and become a larger dimensionalgrowth unit in a one-dimensionaldirection.Then HSO_4^- and larger dimensionalgrowth units connect as basic magnesium sulfate whiskers,according to the structuralcharacteristics of the basic magnesium sulfate whisker,which can guide the synthesis of magnesium hydroxide whisker.

SEIHCRD Model for COVID-19 Spread Scenarios,Disease Predictions and Estimates the Basic Reproduction Number,Case Fatality Rate,Hospital,and ICU Beds Requirement

We have proposed a new mathematical method,the SEIHCRD model,which has an excellent potential to predict the incidence of COVID-19 diseases.Our proposed SEIHCRD model is an extension of the SEIR model.Three-compartments have added death,hospitalized,and critical,which improves the basic understanding of disease spread and results.We have studiedCOVID-19 cases of six countries,where the impact of this disease in the highest are Brazil,India,Italy,Spain,the United Kingdom,and the United States.After estimating model parameters based on available clinical data,the modelwill propagate and forecast dynamic evolution.Themodel calculates the Basic reproduction number over time using logistic regression and the Case fatality rate based on the selected countries’age-category scenario.Themodel calculates two types of Case fatality rate one is CFR daily,and the other is total CFR.The proposed model estimates the approximate time when the disease is at its peak and the approximate time when death cases rarely occur and calculate how much hospital beds and ICU beds will be needed in the peak days of infection.The SEIHCRD model outperforms the classic ARXmodel and the ARIMA model.RMSE,MAPE,andRsquaredmatrices are used to evaluate results and are graphically represented using Taylor and Target diagrams.The result shows RMSE has improved by 56%–74%,and MAPE has a 53%–89%improvement in prediction accuracy.

Investigation of Automatic Speech Recognition Systems via the Multilingual Deep Neural Network Modeling Methods for a Very Low-Resource Language, Chaha

Automatic speech recognition (ASR) is vital for very low-resource languages for mitigating the extinction trouble. Chaha is one of the low-resource languages, which suffers from the problem of resource insufficiency and some of its phonological, morphological, and orthographic features challenge the development and initiatives in the area of ASR. By considering these challenges, this study is the first endeavor, which analyzed the characteristics of the language, prepared speech corpus, and developed different ASR systems. A small 3-hour read speech corpus was prepared and transcribed. Different basic and rounded phone unit-based speech recognizers were explored using multilingual deep neural network (DNN) modeling methods. The experimental results demonstrated that all the basic phone and rounded phone unit-based multilingual models outperformed the corresponding unilingual models with the relative performance improvements of 5.47% to 19.87% and 5.74% to 16.77%, respectively. The rounded phone unit-based multilingual models outperformed the equivalent basic phone unit-based models with relative performance improvements of 0.95% to 4.98%. Overall, we discovered that multilingual DNN modeling methods are profoundly effective to develop Chaha speech recognizers. Both the basic and rounded phone acoustic units are convenient to build Chaha ASR system. However, the rounded phone unit-based models are superior in performance and faster in recognition speed over the corresponding basic phone unit-based models. Hence, the rounded phone units are the most suitable acoustic units to develop Chaha ASR systems.

Analysis of Yield Components of Japonica Rice Tong Jing 981 under Different Density and Fertilization Conditions

The yield and yield components of Japonica variety Tongjing 981 under different density and fertilization levels were studied through regression and correlation and path analysis. The results showed that the number of panicles per unit area, number of filled grains per panicle and 1 000-grain weight all had very significant yield increasing effects, and the number of panicles per unit area played a leading role. However, the yield increasing effects of the number of panicles per unit area and number of filled grains per panicle are equally important when the basic seedlings are more or the N fertilizer application rate is large. In practical production, a major factor should be determined among the yield components, and rational cultivation measures should be taken accordingly, to improve yield.

考虑运行图抽线调整的城际铁路动车周转计划编制

针对现有城际铁路动车组周转计划编制方法未考虑运行线客座率分布,导致抽线调整时难以单独停运低客座率车次而不影响高客座率车次的问题,本文提出一种适用于运行图抽线调整的动车组周转计划优化编制方法。以最小化动车组使用数量及交路中运行线客座率差异为目标,考虑满足一级修等约束条件,构建非线性整数规划模型;通过线性化处理并结合Hierholzer's算法筛选合格解的方式,高效求解模型。案例分析表明:相较于只考虑动车组使用数量的传统方法,该模型在不增加动车组使用数量的情况下,可以显著降低各交路中运行线客座率的差异。优化后的交路中运行线客座率极差提高了68.67%,交路中运行线客座率方差之和降低至对比方案的66.27%。抽线调整时,采用优化方案能够更精确地优先取消低客座率运行线,有效保留高客座率运行线。在抽线条数分别设定为1,2,3的情况下,优化方案停开的运行线中,客座率低于60%的运行线的占比均保持在77%以上,而对比方案中该比例均未超过45%;优化方案中被取消车次的平均客座率比对比方案分别降低了4.48%、5.88%和6.01%。
