Volume: 62

Issue: 27

Page Range: 1089-1098

Description:

Introduction: Professionals working in the social sector typically do significant overwork in rather unfavourable working conditions. Although the purpose in life is proved to determine the areas of career, health awareness, and the quality of life, the latter has not yet been confirmed among social workers. Objective: The purpose of this research is to demonstrate body composition and fitness status as well as the quality of life of female employees (n = 127) at a social institution, furthermore the decisive role purpose of life plays in these indicators. Method: Data were collected through questionnaires, tests, body composition analyses, and fitness status tests, and were assessed by t-test, analysis of variance and regression analysis. Results: Body composition of the participants indicates a generally overweight status, while fitness status, quality of life, and purpose of life are within the acceptable range, however, all with notable range values. Those with a higher-level purpose of life demonstrate better fitness indicators and higher quality of life. In terms of body composition, fitness, and quality of life, only a minor difference was found between those who do intellectual and physical type of work. Those who took sick leave demonstrated a lower level of fitness and quality of life compared to those who did not take any sick leave. Body composition and fitness status have proven to deteriorate with age. Conclusion: Previous research findings can be confirmed by stating that neither the body composition and fitness indicators, nor the quality-of-life level of social workers are optimal. The determining role of purpose in life has been proven in substantial aspects in this study. One of the focus areas of enhancing purpose in life is the workplace, where major positive impacts can be achieved in terms of the physical and mental health, well-being, and work performance.

The P-graph approach for systematic synthesis of wastewater treatment networks

Publication Name: Aiche Journal

Publication Date: 2021-07-01

Volume: 67

Issue: 7

Page Range: Unknown

Description:

Wastewater treatment consists of three or four sequential stages: preliminary, primary, secondary, and tertiary. Each stage can comprise multiple alternative technologies that can perform the same tasks with different efficiencies, operating times, and costs. Thus, we propose a systematic approach for designing wastewater treatment networks by utilizing principles of mathematical modeling and generating an exhaustive enumeration of all the possible technologies and their connections during the early stages of designing a treatment facility. Some of these structures are nonintuitive and include recycling, reprocessing, bypasses, and multiple technologies in parallel or series to remove the same contaminant. The nonintuitive structures with multiple technologies may provide a measure of resilience compared to typical heuristic designs. Thus, the combination of P-graph methodology and the sequence of treatment technologies predicted via the optimization algorithm from the maximal structure is based on holistic considerations and does not lead to suboptimal solutions.

Statistical approach for designing generic 18650 battery model

Publication Name: 2021 17th Conference on Electrical Machines Drives and Power Systems Elma 2021 Proceedings

Publication Date: 2021-07-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

Most battery models are designed by estimating its parameters of one or two different cells. During simulations, these models perform satisfactorily and produce results very close to reality. The problem occurs when measurements are conducted with cells from different manufacturers and large variations are observed during the dynamic loads. The purpose of this paper is to design a general model for 18650 designed batteries, which provides as little deviation as possible when using different cell types. To establish the general model, constant load, transient, and dynamic load tests on 8 different cells are performed. An Ordered Weighted Averaging operator is used to standardize the measurement results and determine the model parameters. Outliers are filtered out using the weight parameter. To create the battery model a two-time-constant circuit model is used in MATLAB Simulink. Worldwide Harmonized Light Vehicle Test Procedure (WLTP) tests are used to validate the results.

Exploring the rosmarinic acid profile of dark chocolate fortified with freeze-dried lemon balm extract using conventional and non-conventional extraction techniques

Publication Name: Lwt

Publication Date: 2021-07-01

Volume: 147

Issue: Unknown

Page Range: Unknown

Description:

The present study evaluated the feasibility of the fortification of dark chocolate with a freeze-dried lemon balm extract rich in rosmarinic acid (RA). Given the food matrix used, it was necessary to develop an analytical and extraction method for RA determination in fortified chocolate. A simple and efficient reversed-phase high-performance liquid chromatography method (RP-HPLC) has been developed for the estimation of RA in dark chocolate. The validity of the method was demonstrated by evaluating the system suitability, linearity, precision, accuracy, the limit of detection, and limit of quantification. The extraction of RA from chocolate was optimized using maceration with shaking (MACS) and microwave-assisted extraction (MAE). The experimental conditions, namely solvent type and extraction time, were optimized using the one-factor-at-a-time methodology. Under the optimized conditions, the proposed method showed good recovery within 95% and acceptable reproducibility with intra- and inter-day relative standard deviations of <2.3%. The method was linear from 5 to 800 μg/mL with a determination coefficient of 1.000. Moreover, the functional chocolate showed a homogeneous active ingredient distribution and retained its RA amount since no significant difference was observed during storage. Overall, the present method was successfully applied to determine RA content in fortified chocolate.

Publication Name: Symmetry

Publication Date: 2021-07-01

Volume: 13

Issue: 7

Page Range: Unknown

Description:

This paper deals with the flow shop scheduling problem. To find the optimal solution is an NP-hard problem. The paper reviews some algorithms from the literature and applies a benchmark dataset to evaluate their efficiency. In this research work, the discrete bacterial memetic evolutionary algorithm (DBMEA) as a global searcher was investigated. The proposed algorithm improves the local search by applying the simulated annealing algorithm (SA). This paper presents the experimental results of solving the no-idle flow shop scheduling problem. To compare the proposed algorithm with other researchers’ work, a benchmark problem set was used. The calculated makespan times were compared against the best-known solutions in the literature. The proposed hybrid algorithm has provided better results than methods using genetic algorithm variants, thus it is a major improvement for the memetic algorithm family solving production scheduling problems.

Publication Name: Nova Biotechnologica Et Chimica

Publication Date: 2021-06-23

Volume: 20

Issue: 1

Page Range: Unknown

Description:

A crop growing in the right quantity and quality can only be secured if nutrients are provided in an adequate quantity and available form. Copper (Cu) has primary importance among microelements in growing winter wheat. Lack of Cu hinders nitrogen uptake by plants. Therefore, increasing bioavailability is important in crop production. It has been conducted successful foliar fertilisation experiments with Tetraamminecopper(II) sulphate for several years. The efficiency of the applied compound was enhanced by the application of a retarded nutrient-supply. To secure retardation, ion exchange was carried out in NaA type synthesized zeolite with Tetraamminecopper(II) sulphate. Structure of Tetraamminecopper(II) sulphate, and zeolite ion-exchanged by copper-tetraamine was analysed with a derivatograph and X-ray diffraction. Derivatograph analyses revealed heat stability. X-ray diffraction analyses revealed that copper-tetramine ions exchanged a significant part of the sodium ions of zeolite in ion exchange.

Reviving an unpopular tourism destination through the placemaking approach: Case study of Ngawen temple, Indonesia

Publication Name: Sustainability Switzerland

Publication Date: 2021-06-02

Volume: 13

Issue: 12

Page Range: Unknown

Description:

Changes in tourists’ behavior in recent times have been considered a driving force for emphasizing the importance of unpopular tourism destinations as one of the key potentials in the tourism industry in any nation. On the road to reviving unpopular tourism destinations, this study aims to identify the potential tourism aspect and development of the Ngawen Temple in Indonesia. This research applies the placemaking approach as the main strategy for resurrecting Ngawen Temple. By using visitor surveys, visitor flows, and community surveys, this research obtains a clearer assessment for determining the planning development of Ngawen Temple. The research results revealed that unpopular destinations still have the potential to be developed and bring more benefits to the local economy by conducting a comprehensive placemaking approach. Accordingly, possible strategies based on various literature and field observations can provide clues to stakeholders on how to use their tourism assets to improve local communities’ economies. Some of the most frequently proposed strategies are the following: link the unpopular destination with other popular ones through structured tourism trips; design a “tourist trap,” which is a created place to hold tourists longer in a destination using new additional facilities; improve the infrastructure; and establish more creative tourism spaces, such as tourism centers.
