Using functional traits to predict pollination services: A review
Authors: Greenop Arran , Woodcock Ben , Pywell Richard F. 
Published: October 2023

Pollination is a fundamental ecosystem service. Predictive and mechanistic models linking pollinator community structure to pollination services increasingly incorporate information on unique functional differences among species, so called effects traits. There is little consensus as to which traits are most important in supporting pollination services at either an individual or community level. Here, we synthesise the state of current knowledge regarding the role and efficacy of traits for predicting pollination, as well as the use of different methods for describing the trait structure of pollinator assemblages. We find a wide range of traits are currently used to predict pollination services, including morphological, behavioural and phenological characteristics. However, we show that the evidence demonstrating their importance is often limited or mixed. There is a trade-off in how traits are used between those that are easier to measure, available for many species but have only limited evidence for their role in pollination, vs. those that are harder to measure but with a more robust link with pollination service delivery. We highlight how community weighted means and measures of functional diversity offer important, albeit different insights into pollination service delivery. We discuss how their relative importance is likely to depend on the goals of the study. To maximise fully the utilisation of traits to predict pollination services, future research should be directed towards the widespread and consistent validation of the links among different traits and the pollination service across crop and semi-natural plant communities. Ideally this also needs to address geographical and taxonomic biases in trait collection.

Microtremor and geoelectrical resistivity surveys have been conducted in areas where the April 10, 2021, earthquake of 6.1 Mw caused the most damage. Wirotaman Village, Malang Regency, was one of the regions with the most extensive damage. This study aims to investigate the seismic vulnerability and subsurface conditions that result in severe damage at the research location. This study's Horizontal to Vertical Spectral Ratio Analysis (HVSR) curve was derived from the recorded microtremor signal in the frequency domain. The frequency parameter and amplification factor obtained from the curve are used to determine the seismic vulnerability index. In addition, a geoelectrical resistivity study with a dipole-dipole configuration was conducted at the site with the most extensive damage. The results of this study show the correlation between the results of the HVSR curve analysis and geoelectrical resistivity in determining the seismic vulnerability of an area. The results indicated that the high seismic vulnerability index value ranged from Kg= 12.0 to 18.0, with the most severe damage concentrated in the Southwest at SA 05 and SA 06. Based on the results of the geoelectrical survey, information was obtained that several points of damage to buildings at SA 05 (red circle) were on the same line, where this condition was associated with the possibility of new faults at that location. This microtremor and geoelectric resistivity investigation reveals thick sedimentary deposits with a high seismic vulnerability index and low resistivity. This study's findings can be utilized as a guide for micro zonation studies in research areas. This research contributes to the surrounding community in the form of disaster mitigation, where construction must avoid local fault positions that have been found to reduce the level of damage when natural geological disasters occur.

Effect of Openings on the Torsional Behavior of SCC Box Beams Under Monotonic and Repeated Loading
Authors: Mahdi Haneen Maad , Abbas Rafaa M. 
Published: October 2023

Repeated Torsional loading occurs in many concrete structures, such as offshore structures, freeways, multistory parking garages, and other structures; however, repeated torsional loading is still poorly understood. This study aims to investigate the effect of openings on the ultimate and cracking torques, angle of twist, and modes of failure of self-compacted R.C. box beams under monotonic and repeated loading. Two groups of eight half-scale box beams with different numbers of circular openings in the web with a diameter of about 30% of the hollow box dimension were investigated. The first group (I) included four beams: one was the control box beam without openings, whereas the rest of the beams were hollow with one, two, or three openings in the web tested under monotonic loading. The second group (II) consisted of the same details as the first one tested under repeated loading. The range of the repeated loading was about 30% and 60% of the ultimate load of the monotonic tests. The study showed that the cracking and ultimate torques and the angle of twist of the tested beams were significantly reduced due to openings in the web. Results revealed a more pronounced effect for monotonic loading, with a maximum reduction of 20% and 26.8% in cracking and ultimate torsional strength, respectively, compared to monotonic loading. Moreover, results revealed that repeated loading causes inelastic deformations in proportion to the number of loading cycles. Doi: 10.28991/CEJ-2023-09-09-015 Full Text: PDF

Published: October 2023

This study addresses unused recycled asphalt pavement (RAP) incorporated into sedimentary soil from the Guabirotuba Formation in Curitiba, Southern Brazil. Different percentages of RAP, ranging from 0% to 80% by weight, were mixed with the pure soil, with and without the addition of pozzolanic Portland cement. Tests were conducted to evaluate the mixtures' compaction properties, mechanical strength, and expansion after curing for up to 28 days. The results showed that adding RAP improved the mixtures' unconfined compressive strength (qu) and splitting tensile strength (qt). Up to 60% RAP, the qu increased by 260 kPa, and the qt increased by 340 kPa compared to the pure soil. The California Bearing Ratio (CBR) tests demonstrated an 18.62% improvement when 80% RAP was added to the untreated soil. In addition, the RAP also reduced the expansion of the compacted blends, with values decreasing from 1.19% to 0.88% with 80% RAP replacement. The expansion value was further reduced to 0.86% when the cement was added. The cement-soil-RAP compacted blends showed suitability for subgrade reinforcement, meeting the criteria of expansion <1% and CBR> 2%. Additionally, 3% cement and 40% RAP mixtures were suitable as a sub-base layer, with expansion <1% and CBR > 20%. The results provide valuable insights into utilizing RAP as an alternative material in soil improvement techniques employing the novelty porosity-to-cement index.

Published: October 2023

Plastic waste (PW) is a major soild waste, which its generation continues to increase globally year in and year out. Proper management of the PW is still a challenge due to its non-biodegradable nature. One of the most convenient ways of managing plastic waste is by using it in concrete as a partial substitute for natural aggregate. However, the main shortcomings of adding plastic waste to concrete are a reduction in strength and durability. Hence, to reduce the undesirable impact of the PW in concrete, highly reactive additives are normally added. In this research, 240 experimental datasets were used to train an artificial neural network (ANN) model using Levenberg Marquadt algorithms for the prediction of the mechanical properties and durability of high-volume fly ash (HVFA) concrete containing fly ash and PW as partial substitutes for cement and coarse aggregate, respectively, and graphene nanoplatlets (GNP) as additives to cementitious materials. The optimized model structure has five input parameters, 17 hidden neurons, and one output layer for each of the physical parameters. The results were analyzed graphically and statistically. The obtained results revealed that the generated network model can forecast with deviations less than 0.48%. The efficiency of the ANN model in predicting concrete properties was compared with that of the SVR (support vector regression) and SWLR (stepwise regression) models. The ANN outperformed SVR and SWLR for all the models by up to 6% and 74% for SVR and SWLR, respectively, in the confirmation stage. The graphical analysis of the results further demonstrates the higher prediction ability of the ANN. Doi: 10.28991/CEJ-2023-09-09-04 Full Text: PDF

Published: October 2023

Peat in various phases of decomposition has poor shear strength and high compressive deformation. For this research study, it will focus on stabilizing peat soil using NaOH. There are two main tests that were conducted in this research study, which are index property testing and the compaction test. For index property testing, there were six (6) experiments conducted to study the index properties of disturbed peat soil, which are moisture content, fiber content, organic content, liquid limit, pH, and specific gravity. Then, for the compaction test, a 4.5kg rammer was used to determine the best mixture of stabilizer blended with different volumes of 5%, 7%, and 9% stabilizer. The desired outcome of this study is to stimulate further research into the use of the chemical NaOH as a peat soil stabilizer for improved soil usage. 7% and 9% of NaOH only have a slightly different percentage, and it can be concluded that this was the optimum percentage of NaOH as a chemical stabilizer for peat soil. It can be seen clearly that 5% is the higher dry density with a lesser moisture content of the peat. When the percentage of NaOH was increased, the graph pattern also changed. NaOH has been observed as an alteration agent for peat soil dry density. It can be seen clearly that 5% NaOH is the higher dry density of the peat with the lesser moisture content and is suitable as a peat soil stabilizer. The increment of oxygen content recorded changes from 13.3% to 23%, while the sodium (Na) content decreased significantly with the increment of oxygen (O). Sodium content decreased from 8.7% for untreated specimens to 4.5% and 5.5% when peat was treated with NaOH, with 5% of NaOH and 9% of NaOH. Doi: 10.28991/CEJ-2023-09-09-09 Full Text: PDF
HEALTH EMERGENCIES POST COVID-19: WHAT GUIDANCE CAN AFRICA’S DISABILITY PROTOCOL PROVIDE?
Authors: Mgijima-Konopi Innocentia , Auma Mary 
Published: October 2023

Several African countries recorded their first cases of the coronavirus disease (COVID-19) in March 2020, the same month the World Health Organisation (WHO) declared it a global pandemic. Within three months the virus has spread throughout the continent. By 29 December the Africa Centres for Disease Control and Prevention put the total number of COVID-19 cases in Africa at 2.6 million with 63 300 deaths recorded. Though there are no official statistics on the number of persons with disabilities in Africa who have tested positive for or succumbed to COVID-19, the Working Group on The Rights of Older Persons and People with Disabilities in Africa in its statement on International Day of Persons with Disabilities acknowledged the potential heightened vulnerability of persons with disabilities on the continent to the pandemic reiterating that many persons with disabilities have pre-existing health conditions that may make them more susceptible to contracting the virus and experiencing more severe symptoms, leading to elevated mortality rates. The discussion that follows focuses on aspects of the monitoring report related to gaps in the protection of right to health of persons with disabilities in Africa during the pandemic. The commentary will use the survey results to illustrate how the Protocol to the African Charter on Human and Peoples’ Rights on the Rights of Persons with Disabilities in Africa (African Disability Protocol), once in effect, may provide additional guidance to states in responding more effectively to the health needs of persons with disabilities during possible further ‘surges’ of the COVID-19 pandemic as well as future health care emergencies. It concludes with a call for African states to expediently ratify the African Disability Protocol so it can come into force.

Background The prevalence of people who are overweight or obese is increasing globally, especially in low- and middle-income countries. High body mass index (BMI) among women of reproductive age is a risk factor for various adverse reproductive and pregnancy outcomes. This study aims to describe trends over time in the distribution of BMI among Tanzanian women of reproductive age intending to conceive between 2004/5 and 2015/16, and identify factors associated with high BMI. Methods We used data on 20,819 women of reproductive age (15-49 years) intending to conceive who participated in the Tanzania Demographic and Health Surveys in 2004/5, 2010 and 2015/16. We estimated the prevalence of high BMI (being overweight [≥25 to <30 kg/m2] and obesity [≥30kg/m2) and trends in the prevalence of high BMI across the three surveys. Using survey-weighted multivariable logistic regression, we used the most recent 2015/16 survey data to identify factors associated with high BMI. Results Median BMI increased from 21.7kg/m2 (inter-quartile range, IQR=19.9-24.1 kg/m2) in 2004/5 to 22.0 kg/m2 (IQR=20.0-24.8 kg/m2) in 2010 to 22.7 kg/m2 (IQR=20.4-26.0 kg/m2) in 2015/16. The prevalence of overweight women increased from 11.1% in 2004/5 to 15.8% in 2015 (P <0.001). The prevalence of obesity increased from 3.1% in 2004/5 to 8.0% in 2015/16 (P<0.001). Women in the highest wealth quintile had higher odds (adjusted odds ratio, aOR= 4.5; 95%CI 3.4-6.3, P<0.001) of high BMI than women in the lowest quintile. The odds of high BMI were about four times greater (aOR=3.9; 95%CI=2.9-5.4, P<0.001) for women 40-44 years compared to 20–24-year-olds. Women in the high-paying occupations had greater odds of high BMI than those working in agriculture (aOR=1.5; 95% CI=1.1-2.2, P=0.002). Women residing in the Southern zone had 1.9 (95%CI=1.5-2.5, P<0.001) greater odds of high BMI than Lake zone residents. Conclusions In Tanzania, high BMI affects almost 1 in 4 women of reproductive age who intend to conceive. This contributes to the burden of poor maternal and reproductive health outcomes. We recommend developing and implementing health-system strategies for addressing high BMI, tailored to the modifiable risk factors identified among women of reproductive age.
Barriers, promoters, and strategies for improving task shifting and task sharing implementation in Nigeria: qualitative perspectives of policymakers
Authors: Okoroafor Sunny C , Christmals Christmal Dela 
Published: October 2023

Background Nigeria developed a National Task Shifting and Sharing Policy due to protracted inequitable distribution of health workers, especially at the primary level of care, and the low stock and production rate of skilled health workforce. Following the development of Nigeria’s task shifting and sharing policy and strategy, implementation was promulgated at various levels, with States adopting and implementing the national policy. However, the policy environment for task shifting and sharing varies widely. Consequently, evidence on barriers to and factors promoting successful implementation are inconclusive. Hence, strategies for improving implementation are needed. The evidence from this study can inform the scale-up and strengthening of implementation approaches as Nigeria strives to achieve the national goals, universal health coverage and sustainable development goals. Methods An explorative, descriptive research study approach was applied with 20 key informant interviews conducted to explore the perception of policymakers on barriers and promoters of task shifting and sharing in Nigeria. In addition, strategies for improving task shifting and sharing implementation were explored. Results The barriers to effective implementation of task shifting ad sharing from our study were the persistent shortage of health workers, inter-cadre rivalry, perceived sub-optimal capacity of the beneficiary cadres, and lack of adequate equipment for delivery of needed services. The factors promoting the implementation of task shifting and sharing were the availability of adapted policies, the political will of the health sector leadership, acceptance of task shifting and sharing implementation by health workers, and the implementation of actions to improve knowledge and skills of health workers to implement shifted or shared tasks by various actors. The strategies to improve future task shifting and sharing implementation include improving staffing levels, scaling up training and periodic retraining, mentoring and supportive supervision, and improving the, use and dissemination of evidence generated. Conclusions Several factors influence the implementation of task shifting and sharing. Hence the identification and implementation of relevant strategies are pertinent in achieving set objectives and national goals. In policy and practice, therefore, a proactive exploration of the contextual understanding, barriers to implementation, enablers and learning from the performance of similar interventions is pertinent in shaping strategies for translating evidence to practice through an implementation framework. This should be done in collaboration with stakeholders to foster acceptance and participation.

Published: October 2023

<p>This paper presents a reliability, availability, and maintenance (RAM) analysis framework to evaluate the performance of Power Generation Machines (MPL) as part of office infrastructure. MPL performance is evaluated by calculating maintenance performance, including Mean Time Between Failures (MTBF) to see reliability aspects, Mean Time to Repair (MTTR) to see maintainability aspects, and availability to see its operational availability. This research used data as maintenance log sheet data from three MPLs from January to September 2021. The results showed that MPL1 had the most optimal condition with an availability value of 93.48%, MPL2 was 82.19%, and MPL3 was 70.55%. Root cause analysis was carried out using Fishbone Diagram. It was able to identify the main problems in the machine's age and the procedure for submitting maintenance. Maintenance performance improvement is very much needed, especially the availability aspect for MPL2 and MPL3, as well as the valuation of existing preventive care. In addition, determining qualification standards for availability, MTBF, and machine MTTR needs to be carried out as a quantitative consideration in making MPL replacement decisions.<strong></strong></p><p> </p>
