The Contributory Pension Scheme (Cps) and Sufficiency of Retirement Benefit of the Low Income Retirees of the Federal Public Service in Nigeria

This study examined the level of sufficient retirement benefit under the contributory pension scheme emanating from the pool of savings contributed that can suffice to provide the minimum needed livelihood. The secondary data of all pension contributions and retirement benefits were retrieved from series of publications of PenCom from the years 2004 to 2022. The primary data population consists of 1316 retirees. EasyFit 5.6 Professional Software together with the Least Square Model, accumulation and annuity formulae was employed to analyse the secondary data and the responses from the respondents during survey. Arising from the data collected and the analysis carried out using the Consolidated Public Service Salary Structure, the level of comfort of low income retirees who spent 20 to 35 years in active service is nothing to write home about due to insufficient pension benefits as a result of the challenges investigated. The study recommends the implementation of minimum pension derived with requisite modalities of 20 years as the minimum qualifying length of service and only 10-year post retirement subsidy.

Adaptive Switching Event-Triggered Control for Active Suspension Systems With Acceleration Performance Constraint

This work focuses on an adaptive control problem for active suspension systems (ASSs) with the acceleration performance constraint over the controller area network (CAN). We aim to develop an effective event-triggered control technique to significantly reduce the communication burden of the CAN. To this end, an event-triggered mechanism based on the switching threshold is developed to obtain satisfactory suspension performances while greatly improving the network resource utilization on the CAN. In particular, the threshold parameters are adjusted according to road conditions, which enhances the flexibility of the event-triggered mechanism in face of different road excitation. Then, we propose a novel adaptive algorithm based on the acceleration constrained model by means of which the method ensures that the maximum overshoot of the vehicle acceleration cannot be violated. Moreover, under the presented control strategy, the performance requirements in the resulting closed-loop ASSs are guaranteed, while the tracking error of the vertical displacement converges to a small region. Finally, simulation results by using the simulator consisting of the professional vehicle simulation software Carsim and MATLAB/Simulink are provided to demonstrate the effectiveness of the proposed methodology.

Analysis of Influence of Pre-bend Blade Shape on Aeroelastic Characteristics of Wind Turbine Under Startup Condition

In this paper, a 2 MW wind turbine in the laboratory is taken as the research object, and the blades with pre-bending capacities of 2, 3, 4, and 5 m are designed, respectively, to study the influence of different pre-bending capacities on the aerodynamic elasticity of wind turbine under unstable operating conditions. Based on the professional simulation software of wind turbine multi-body dynamics, the parametric model with aero-elastic-control coupling is established, and the simulation calculation of different pre-bending blades is carried out. The results show that the aerodynamic deformation of the blade and the load at the blade root increase obviously with the increase of blade pre-bending. Under the starting condition of a wind turbine, larger blade pre-bending will lead to a significant increase in aerodynamic deformation of wind turbine blades under unstable operating conditions. It shows that the larger blade pre-bending amount will greatly increase the risk of aeroelastic instability of wind turbines under unstable operating conditions.

IDENTIFICATION OF SUBSURFACE STRUCTURES IN SOUTH BENGKULU MANNA CITY BASED ON THE MASW METHOD

South Bengkulu is one of the regencies in Bengkulu Province which is in an area of active tectonic plate activity, namely the India-Australia and Eurasian plates so it is prone to earthquakes. The City of Manna continues to carry out developments so that it requires various information for urban and regional planning, especially information on subsurface rock structures. This study aims to determine the structure of rock layers based on shear wave velocity (Vs), Poisson ratio, shear modulus and Young's modulus in Manna City. This research was conducted using the Multichannel Analysis of Surface Wave (MASW) method at 12 measurement stations. The tool used is the PASI 16S24-P seismograph. Data processing to produce a 1D model is WinMASW 5.0 Professional Software and to display 3-D data Voxler software is used based on the value of Vs. Then do the calculation to get the value of Vs30. From the results of the Vs30 value in the study area, it shows that the Manna City area consists of 4 rock types including soft soil (SE), stiff soil (SD), very dense soil and soft rock (SC) and rock (SB) rock types. The highest layering value of shear wave velocity (Vs) is at the fourth point with a value of Vs 386-1263 m/s, Poisson ratio 0.40-0.35, shear modulus 298-3652 MPa and Young's modulus 804-9430 MPa at a depth of 4.4 -30 meters. While the smallest value is at the sixth location point with a value of Vs 180-474 m/s, Poisson ratio 0.40-0.30 shear modulus 60-461 MPa, and Young's modulus 168-1.243 MPa at a depth of 2.6-30 meters.

Use of Acoustic Camera for Noise Sources Localization and Noise Reduction in the Industrial Plant

The paper presents results of the localization of main noise sources in the industrial plant. Identification of main noise sources was made with an acoustic camera using Beamforming Method. Parallel to the measurements by means of the acoustic camera, sound level measurements on the main noise sources have been performed. Based on the calculations, prediction regarding the noise emission at residential buildings located near to the plant has been determined. Acoustic noise maps have been performed with LEQ Professional software, which includes the 3D geometry of the buildings inside the plant. It has been established that, after introduction of noise reduction measures in the plant, the noise levels at the observation points in the residential area meets the limit values.

Is a non-radiological-assisted method valid for establishing crown-root relationships in an orthodontic set-up incorporating the roots? A retrospective study

This study aimed to obtain information on the relationship between crown and root in terms of morphology - dimensions and crown-root angles -to be used for orthodontic set-ups without the use of radiological examinations. All the good quality CBCTs of patients obeying the eligibility criteria, from 2000 to 2015, were analysed. All teeth were analysed except for third molars. Six variables were evaluated: crown (CL) and root length (RL), crown width (CW), root width (RW), crown-root angles in both the frontal (CR-frontal) and sagittal plane (CR-sagittal). All teeth were divided into 3 groups according to number of root (single, two, three-rooted). The measurements were assessed with the Invivo professional software and then, subjected to correlation matrices and linear regression statistical analysis in order to find any significant correlations between crown and root measurements (α≤0.05). Seventy-three out of 247 good quality CBCTs were assessed. Correlation matrices statistical analysis showed linear correlations for some variables investigated, especially for CW/RW pairing in all subgroups (r=0.81, r=0.70 and r=0.58 respectively for single-, two- and three-rooted) and CL/RL in the single-rooted subgroup (r=0.29). Subsequent linear regression analysis allowed to obtain information about roots starting from crown measurements by means of equations [RW=0.76+(0.73×CW) and RL=10.94+(0.25×CL) for single-rooted teeth; RL=1.11+(0.73×CW) and RW=0.99+(0.76×CW), respectively for single- and two-rooted teeth]. No linear correlation was found between crown measurements and C-R angular values. It is possible to obtain root information starting from some crown measurements but these do not fulfil the need of minimal information to guarantee a perfect root position starting from that of crown.

Comprehensive review of MS-based studies on N-glycoproteome and N-glycome of extracellular vesicles.

Extracellular vesicles (EVs) are lipid bilayer-enclosed particles that can be released by all type of cells. Whereas, as one of the most common post-translational modifications, glycosylation plays a vital role in various biological functions of EVs, such as EV biogenesis, sorting, and cellular recognition. Nevertheless, compared with studies on RNAs or proteins, those investigating the glycoconjugates of EVs are limited. An in-depth investigation of N-glycosylation of EVs can improve the understanding of the biological functions of EVs and help to exploit EVs from different perspectives. The general focus of studies on glycosylation of EVs primarily includes isolation and characterization of EVs, preparation of glycoproteome/glycome samples and MS analysis. However, the low content of EVs and non-standard separation methods for downstream analysis are the main limitations of these studies. In this review, we highlight the importance of glycopeptide/glycan enrichment and derivatization owing to the low abundance of glycoproteins and the low ionization efficiency of glycans. Diverse fragmentation patterns and professional analytical software are indispensable for analysing glycosylation via MS. Altogether, this review summarises recent studies on glycosylation of EVs, revealing the role of EVs in disease progression and their remarkable potential as biomarkers.

Evaluation of green hydrogen production using solar, wind, and hybrid technologies under various technical and financial scenarios for multi-sites in Egypt

The importance of energy storage is increased with the intermittent nature of renewable energy resources (RERs). Green hydrogen is increasingly being employed to address its shortcomings. Furthermore, lowering carbon emissions has accelerated the quest for green alternatives instead of fossil-based fuels. This research focuses on Egypt's capacity to generate green hydrogen using natural renewable resources to serve islanded electrical and hydrogen loads. To obtain the lowest net present cost (NPC), cost of hydrogen (COH), and levelized cost of energy (LCOE), the state-of-the-art prices of the system elements are investigated and optimized using the HOMER professional software. Three situations with solar photovoltaic (PV), wind, and hybrid RERs are evaluated in three separate Egyptian cities. A sensitivity analysis is investigated based on the influence of the system's reliability and hydrogen load variance on the cost. The results of the three locations are compared to indicate the best site for green hydrogen production. The results obtained with the wind scenario located on the coast of the Suez Gulf provided the lowest LCOE, ranged from 0.308 $/kWh to 0.353 $/kWh, and the COH ranged from 3.73 $/kg to 4.13 $/kg.

An Empirical Study of Adoption of ChatGPT for Bug Fixing among Professional Developers

ChatGPT is a powerful tool that assists software engineers in identifying and rectifying errors in code. One of its primary advantages is its ability to engage in natural language conversation with humans, which allows it to collaborate more closely with engineers in improving and optimizing the code. However, despite its potential advantages, software developers do not always utilize ChatGPT as a tool for bug fixing. In this study, we aim to examine the factors that influence the adoption of ChatGPT for bug fixing among professional software developers, based on the Unified Theory of Acceptance and Use of Technology (UTAUT) theory. To accomplish this, we conducted 50 semi-structured interviews with professional software developers and other stakeholders. Our findings indicate that the performance expectancy and effort expectancy of professional software developers, as well as social influence, facilitating conditions, data security, and trust are the key factors of adoption. These findings suggest that understanding these factors can be critical in promoting the adoption and use of ChatGPT in the software development industry.

FlexCDMs: A Web-based Platform for Cognitive Diagnostic Data Analysis

Cognitive diagnosis is an important component of modern measurement theory and has received widespread attention from researchers in the fields of education and psychological measurement. Existing cognitive diagnosis analysis tools rely on professional software packages (such as R packages), which creates significant challenges for users, especially those who are not familiar with computer programming. To remove this technical barrier, our team has developed a web-based, user-friendly platform, named flexCDMs, for cognitive diagnosis data analysis. This article describes the features of the platform, the functional modules, the implemented cognitive diagnosis models (CDMs) and algorithms, and illustrates the operations of the platform. This platform can be used to analyze data based on various cognitive diagnosis models, carry out Q-matrix theory, model-data fit tests, parameter estimation, quality analysis of cognitive diagnostic tests, differential item functioning (DIF) detection, and Q-matrix modification. It produces various charts and graphs to report results. It is a powerful, yet easy to use cognitive diagnosis data analysis tool. The website for the flexCDMs platform is: http://111.230.233.68:1001/?Id=false&Block

Analysis of low‐temperature pumped thermal energy storage systems based on a transcritical CO2 charging process

AbstractPumped thermal energy storage (PTES) is a technology for intermediate storage of electrical energy in the form of thermal energy. In this work, PTES systems based on a transcritical CO2 charging process are investigated. A two‐zone water storage tank with a storage temperature of 115°C is used as thermal energy storage. For discharge, an Organic Rankine Cycle (ORC) and, alternatively, a transcritical CO2 heat engine are investigated. The considered concepts are modelled and simulated as stationary processes using the EBSILON Professional software. The scaling is based on an electrical input power of 5 MW. Using an ORC with the working fluid R1234yf for the discharging process results in the highest round‐trip efficiency of 36.8%. The component costs of the different configurations are estimated using cost functions. On the basis of this, the levelized cost of storage (LCOS) is calculated. The configuration with the ORC as the discharging process has the lowest LCOS of 59.2 €cents (kWh)−1. In addition, the technological maturity is determined using the technology readiness level scale. There are no prototypes of the investigated PTES systems yet. Therefore, further investigations must be carried out to implement the technology in the future.

SEPSIS UNIT IN THE EMERGENCY DEPARTMENT: IMPACT ON MANAGEMENT AND OUTCOME OF SEPTIC PATIENTS.

Study hypothesis : Implementation of a new pathway dedicated to septic patients within the emergency department (ED) would improve early management, organ dysfunction, and outcome. Methods: During phase 1, all consecutive adult patients with infection and qualifying quick Sequential Organ Failure Assessment (qSOFA) score upon ED admission were managed according to standards of care. A multifaceted intervention was then performed (implementation phase): educational program, creation of a sepsis alert upon ED admission incorporated in the professional software, together with severity scores and Surviving Sepsis Campaign (SSC) bundle reminders, and dedication of two rooms to the management of septic patients (sepsis unit). During phase 2, patients were managed according to this new organization. Results: Of the 89,040 patients admitted to the ED over the two phases, 2,643 patients (3.2%) had sepsis including 277 with a qualifying qSOFA score on admission (phase 1, 141 patients; phase 2, 136 patients). Recommendations of SSC 3-h bundle significantly improved between the two periods regarding lactate measurement (87% vs. 96%, P = 0.006), initiation of fluid resuscitation (36% vs. 65%, P < 0.001), blood cultures sampling (83% vs. 93%, P = 0.014), and administration of antibiotics (18% vs. 46%, P < 0.001). The Sequential Organ Failure Assessment score between H0 and H12 varied significantly more during phase 2 (1.9 ± 1.9 vs. 0.8 ± 2.6, P < 0.001). Mortality significantly decreased during the second phase, on day 3 (28% vs. 15%, P = 0.008) and on day 28 (40% vs. 28%, P = 0.013). Conclusion: Systematic detection, education, and per protocol organization with a sepsis unit dedicated to the early management of septic patients appear to improve compliance with SSC bundles, organ dysfunction, and short-term mortality. These results warrant to be confirmed by prospective studies.

Definitions of Abnormal Breast Size and Asymmetry: A Cohort Study of 400 Women.

Macromastia, micromastia and breast asymmetry have an impact on health and quality of life. However, there is scarce information addressing breast size and asymmetry frequency distribution in reference populations. The current study aims to identify factors that influence breast size and symmetry and classifies abnormal breast sizes and breast asymmetries in an adult German population. Breast base dimensions, breast volume, symmetry, and other breast anthropometric parameters of 400 German female patients were determined in a retrospective review of the MRI archives at our institution. Professional medical MRI-segmentation software was used for volume measurement. A total of 400 Patients were retrospectively enrolled. The patients had a mean age of 50 ± 12years (min: 24; max: 82), mean BMI of 25.0 ± 5.0 (min: 14.7, max: 45.6), and a mean total breast volume of 976ml (right: 973ml, min: 64, max: 4777; left: 979ml, min: 55, max: 4670). The strongest correlation of breast volume was observed with BMI (r = 0.834, p < 0.001), followed by breast base width (r = 0.799, p < 0.001). Smaller breasts have higher breast volume asymmetry ratios (r = - 0.124, p < 0.014). For a BMI between 18.5 and 24.9kg/m2, micromastia is defined by breast volumes below 250ml (5th percentile) and macromastia by volumes above 1250ml (95th percentile). Abnormal breast volume asymmetry (< 5th and > 95th percentile) is equivalent to an absolute difference of approximately 25% relative to the smallest side (bidirectional asymmetry ratio 5th percentile - 19%; 95th percentile 26%). This study provides normative data of German women, as well as selected size-for-BMI percentiles and asymmetry ratio percentiles. The normative data may help to establish transparent and objective coverage criteria for health insurances. This journal requires that authors assign a level of evidence to each article.

Pengembangan Media Pembelajaran Fisika Matematika Materi Transformasi Koordinat Berbasis E-Modul

Learning physics mathematics is one of the subjects in the physics education study program at the University of Jambi. Based on the results of the questionnaire, students' needs regarding learning mathematics and physics are considered difficult to understand the material taught by lecturers. This is due to the less varied teaching materials and the books used are only sourced from the book Mathematical Methods in Physics written by Mary L. Boas with a thickness of 839 pages consisting of 15 chapters with the language used in English. This is why this research was conducted with the aim of being able to help students with problems when learning mathematics and physics, especially in the material of coordinate transformation using e-modules created using Flip PDF Professional software. The method used is a mixed method with an explanatory design where quantitative data in the form of questionnaire results are strengthened by qualitative data in the form of interviews. Based on the research results, the existence of e-modules can be an alternative in learning that can be used by lecturers and students who are used for independent study with a flexible design that can be used.

Design and construction of a foam-based piezoelectric energy harvester

Generating, converting, harvesting and storing energy are crucial parts of society. This work aims to design and construct a piezoelectric generator that harvests energy from pressure to produce an output voltage capable of charging and powering low-energy electronic devices such as mobile phones and 5 V light bulbs. Proteus 8.0 professional software is used to simulate the circuit for construction. A piezoelectric disc transducer, which is the principal component, was used in the construction. The result shows a voltage of 5–12 V capable of powering low-voltage electronic devices. Amidst the constant instability in electric power systems in Nigeria, those in rural areas have little or no electricity access. Electronic and communication devices are necessary to connect community members to those outside their communities and the world wide web for global information. Children and youths require lighting facilities at school and home for further studies. The design will provide an alternative for energy supply to areas with little or no access to electricity.

Evaluation of eating habits by 7-day food record: web-PC vs. traditional paper format

The aim of this study was to evaluate the validity of a web-based 7-day food-record using METADIETA-web link (Meteda s.r.l.) – a professional software used in nutritional practice and research – compared with the traditional paper format. Twenty-six healthy adults of both sexes were recruited in this cross-over study based on the number coming from the sample size calculation, and randomly assigned to start with METADIETA-web or traditional 7-Day Food-Diary. All the 7-day food-diaries were recorded in the Metadieta-software. The System Usability Scale (SUS) questionnaire was administered to evaluate the participants’ preferences in terms of usability, acceptability, and feasibility. Differences in energy intake, nutrient composition, and SUS between the digital and traditional modalities were evaluated. Energy and nutrients were not significantly different between the two methods with a variation <15%, with alcohol intake showing the strongest relation (0.1% variation). The Interclass Correlation Coefficient showed a grade of consistency between the two methods excellent for alcohol, good for proteins, carbohydrates, and fibre, moderate for energy and saturated fat, and poor for total fat and cholesterol. SUS suggested that the web-based platform was in general well accepted, but highlighted some inconsistencies and complexity compared to the written food diary. The web-based 7-day food-record may allow an accurate and quicker analysis of food timing than conventional approaches, seeming reliable for energy and macronutrient composition, making it a potentially attractive tool for nutritional research. However, the reported inconsistencies and complexity must be considered and addressed.
