Most dining place or restaurant generally still uses manual food ordering process, the service will come to the customer to ask for the food to be ordered. However, during this soaring covid pandemic, the owners are afraid of the spread through waiters who come to customers. For this reason, an application will be made that can provide self-service food orders by customers without having to interact with waiters. Most digitalization efforts only focus on the client aspect of the ordering process and not on the processing of those orders (in the kitchen). This research looks to give an alternative digital ordering system that is integrated with not only the process on the client side but also on the kitchen side.

Impact of Gender on Perceived Work Climate in Business Information Systems
Authors: Disterer Georg
Published: May 2022

Aim/Purpose: The low proportion of women currently working in the field of business information systems presents an opportunity to attract more women to this field. For example, in Germany, the proportion of women studying business information systems is currently 21%, compared to 48% in business administration (Statistisches Bundesamt, 2020). Which characteristics make the professional field of business information systems appear attractive to women and men – and which characteristics do not?

Background: Studies on careers in business information systems are important to mitigate the long-lasting shortage of IT specialists, yet research is limited in this area.

Methodology: To capture empirical data, graduates of the Business Information Systems program at the University of Applied Sciences in Hannover were surveyed.

Contribution: The results show that women and men perceive the work climate and working conditions very differently and are also satisfied to a different extent. Characteristics of the work climate place significantly more restrictions on satisfaction for women than for men. Women primarily criticize characteristics that can be described as involving “a lack of fairness”.

Findings: The differences in perceived work climate may negatively impact the proportion of women in business information systems. A number of measures have already been established to support women in coping better with the prevailing climate. However, some measures bear the risk that women are thus accused of assimilating to the prevailing climate. This can seem pre-sumptuous since the dominant male culture is taken for granted and “set”. Measures for team-building and personnel development appear to be more suitable if these address the actual values and norms of teamwork, question them where necessary, and change them for everyone.

Recommendations for Practitioners: Women’s career goals are clearly different from men’s goals, and women do not achieve goals with high priority very well. Work climate is perceived more critically by women than by men: less fair, less supportive. Advantages of diversity and plurality are put at risk if women should put aside their different “other” perceptions of cooperation and negotiation in order to act according to the rules of the male-dominated system.

Impact on Society: Studies on careers in business information systems are important to mitigate the longer-lasting shortage of IT specialists. The low proportion of women currently working in IT presents an opportunity to attract more women to business information systems.

Published: May 2022

Repairing and retrofitting old civil engineering structures based on reinforced concrete represents a challenge for civil engineering societies all over the world. Environmental impacts such as corrosion and natural disasters like earthquakes can considerably weaken those structures. Reinforced concrete confinement technique using carbon fiber-reinforced polymers (CFRP) is considered as an innovative solution to strengthen the old and damaged structures. In this paper, a numerical simulation was carried out to evaluate the impact of the CFRP jacket as a confining composite material on the compressive strength and the ultimate strain of confined reinforced concrete. A FE model was developed, validated by comparing its results with the available experimental measurements, and finally assessed by performing a parametric study. Indeed, the parametric investigations had as their purpose the evaluation of the level of confinement (different number of plies), namely without plies, one plie, and three plies configuration, that were subjected to different eccentric loading modes e=0, e=25 and e=50 mm, in order to assess the interaction between the combined load that can be represented by compressive and flexural effect. The numerical results were, in fact, in good agreement with the experimental data. In addition, CFRP wrapping had a significant effect on the maximum load of eccentrically loaded columns compared to concentrically loaded columns by increasing the compressive strength with a value of 15% gain compared to the unconfined column. Doi: 10.28991/CEJ-2022-08-04-011 Full Text: PDF
The Effect of Shear Wall Openings on the Response Reduction Factor
Authors: Nasr Nasr E. , Fayed M. N. , Hussien Gamal , El-Makhlasawi A. M.
Published: May 2022

This research attempts to investigate the effect of shear wall openings on the response reduction factor. Openings are commonly necessary because of other engineering disciplines’ requirements. When openings are modest in proportion to the size of the wall, their effects are frequently disregarded. On the other hand, when these openings are large or located in a high-risk area, they can have a significant impact. A broad literature review has been conducted in the present study. A verified comparative example consisting of eight stories was studied. Then, a numerical study has been conducted on two different model sets with 16 and 8 stories, which were designed according to the Egyptian code of loads, ECP-201 (2012), and checked according to the Euro code, EC8 (2004). ETABS software was used to conduct pushover analysis before and after applying different-sized openings. The ground-opening effect has also been studied. The results show that by increasing the opening area, the R-factor was reduced. It is more influenced by the opening height than the width, though. By increasing the number of stories, the reduction percentage in the R-Factor increased for openings that are less than 30% of the wall area. The R-factor increases slightly when half of the reinforcement bars are added. Doi: 10.28991/CEJ-2022-08-04-013 Full Text: PDF
Robust Open-Source Solution for Bridge Decrement Estimation for Data with Outliers
Authors: Owerko Tomasz , Owerko Piotr , Tomaszkiewicz Karolina
Published: May 2022

Dynamic tests enable assessment of the structure’s technical condition and provide information necessary for management and maintenance throughout the object’s life cycle. On their basis, the dynamic characteristics of the object are estimated (e.g., the logarithmic decrement). The possible occurrence of atypical features in the obtained signal (e.g. amplitude beat, outliers), as well as the influence of the type of devices and sensors used for measurements, should be considered. If these features are omitted during the analysis, key dynamic characteristics may be evaluated incorrectly. Therefore, this study presents development of a reproducible, universal and robust open-source algorithm for effective estimation of the logarithmic decrement of bridge structures as a reproducible research. Using the presented approach, it is possible to obtain correct results regardless of the signal’s specificity and its atypical features, as well as the type of devices used to collect data in the in-situ conditions. Two approaches based on the use of advanced regression models are considered to estimate the logarithmic decrement. These are direct non-linear approximation (DNAP) and Hilbert non-linear approximation (HNAP). The enriched HNAPsolution was then implemented as a Python module with a "Signal" class and tested on two independent in-situ examples. The presented approach led to effective and correct estimation of the logarithmic decrement, and proved to be insensitive to the type of bridge, its structural characteristics, atypical features of the obtained signal, and the specificity of the data acquisition techniques. In contrast to methods based on deep machine learning, the presented solution does not require a large learning set representative for a given type of design and works independently of the size of the data sample. As demonstrated in the paper, the solution based on the Hilbert transform allows efficient determination of the damping decrement even in the presence of beat frequencies as well as outlier data. The algorithm works independently of the measurement method, with the necessary functions for preprocessing being implemented in the module itself. The solution has been optimized for improved speed, reliability, and reproducibility of results. Doi: 10.28991/CEJ-2022-08-04-02 Full Text: PDF
Active Earth Pressure Acting on Circular Shafts Using Numerical Approach
Authors: Meftah Abdelmajid , Benmebarek Naïma , Benmebarek Sadok
Published: May 2022

Retaining walls in axi-symmetric conditions and in plane strains have been widely treated in the literature using different approaches (limit equilibrium, limit analysis, slip line, and numerical techniques by finite elements or finite differences). The finite element or finite difference method provides more accurate solutions to the problem than the limit equilibrium method. In this paper, a new model of retaining wall in the axi-symmetry conditions under outward pressure is considered, this case can be widely used in the design of grain silos, buildings and road constructions. Numerical calculations using FLAC are reported to evaluate the evolution of the earth pressure distribution on a cylindrical wall filled with granular material and subjected to radial displacement. A parametric study is carried out in order to evaluate the distribution of the active earth pressure on the wall according to the radius, the angle of friction of the granular material, and the angle of friction of the interface granular material-wall. This study shows that there is an effect of the circular shape and the inclination of the wall on the active earth pressures. Doi: 10.28991/CEJ-2022-08-04-09 Full Text: PDF

PROBLEMATIZING CASTE AND GENDER THROUGH VISUAL METAPHORS AND SIGNIFIERS: READING REGIONAL FILMS
Authors: Swamy D Premila
Published: May 2022

Indian cinema, both Bollywood and regional films have a tremendous impact on the minds of the audience and invariably the society at large. Films respond to various socio-cultural issues prevailing in a society. Apart from being just entertainers, most films have a social message. For effective delivery of the message, films do not rely only on dialogues. In fact, most of the things are conveyed through visuals and signifiers such as sound, pictures, colours, images, symbols, clothes, body language and so on; all pertaining to non-verbal communication. Recent film makers use these cinematic techniques for appropriation. In this context, this article explores the visual signifiers in two regional films; the Tamil film Karnan (2021) and the Malayalam film The Great Indian Kitchen (2021). This research looks at how the visual metaphors and signifiers in both the films foreground the discourses on caste and gender.  The study makes us realize the significance of such cinematography in departing the true spirit/essence of the films.

Understanding Contributions of Divalent Cations in Mineral Carbonation Using Artificial Neural Network
Authors: L.K. Abidoye, , H.B. Oladipo,
Published: May 2022

The roles played by divalent cations (calcium, magnesium and iron) of rock minerals in the efficiency of mineral carbonation have been investigated. Statistical modeling with Artificial Neural Network (ANN) having configuration ANN[17-4-1] shows that carbonation efficiency largely increases as the quantity of calcium content increases. Averagely,there is approximately 5% rise in the original efficiency for 10% increase in the quantity of calcium. This changes to 3.4% and 1.6% increases in efficiency, relative to the original efficiency for 20% and 30% increases in calcium content, respectively. Iron content of minerals offers clear positive correlation to the carbonation efficiency. From the global average, there is approximately 17% rise in the original efficiency for 10% increase in the quantity of iron. This increases to 29% and 41% over the original efficiency for 20% and 30% increases in iron content, respectively.. The influence of magnesium was found to be mainly negatively correlated to carbonation efficiency, after exceeding an unknown threshold. The global average of the efficiency changes with magnesium content results in original efficiency rising by 2% at 10% quantity increase and then reduces by 3% and 9% for 20% and 30% increase in magnesium quantity, respectively, relative to the original efficiency. Thus, iron compounds are found to be most potent of the divalent cations in carbonation reaction while calcium and magnesium content should maintain a threshold ratio with silica content for improved efficiency.

Authors: Mattioli Matteo , Pettino Matteo Valenti , Foresi Andrea , Guidi Diego
Published: May 2022

Offshore engineering projects require the management of a huge amount of heterogeneous georeferenced data - among others metocean, geophysical, geotechnical, and environmental, which need a Data Model, data visualization and data analytics features on a common geographic basis. A Digital Data Platform (DDP) has been developed on a GIS ambient with the aim to speed up the engineering design process (i.e. minimization of routine operations), and also prevent misalignment of the data originating from different sources from Owner to Suppliers and any potential loss of information. The proposed GIS architecture is composed by two main components: i) the Data Model geodatabase, and ii) the GIS-Model Toolbar add-in. The proposed development represents a step forward on the definition of a common specification and dictionary for offshore project execution overcoming the current bottlenecking and inefficiency on the design phases between the project owner and the engineering contractor. The paper illustrates “what” and “how”, and in particular: i) the geodatabase and Data Model framework, ii) the required parameters to be organized and stored for offshore engineering design, and iii) the widgets implementation (i.e. GIS-based tools). Its application on a case study project with practical examples is presented.

Authors: Akhabue Christopher Ehiaguina  , Otoikhian Shegun Kevin
Published: May 2022

This work studies the modelling and optimization of bioethanol production from locally sourced saw dust waste. The saw dust samples are obtained from common wood species in the Nigerian tropical rain forest. Nigeria is one of the producers of wooden products in the world. Many species of wood can be found in Nigeria’s tropical rain forest. Some of the most common wood species include; Astonia boonei (duku), Bombax bounopozense (West African bombax), Brachystegia eurycoma (Okwen), Terminalia superba (White afara). Sawdust samples were obtained from a local saw mill in Edo State, Nigeria. The samples were pre-treated, hydrolyzed, fermented and the bioethanol distilled out. Optimization of bioethanol was performed by using Central Composite design of response surface methodology. Four variables such as acid concentration, hydrolyzing time, hydrolysis temperature and fermentation time were considered as influencing factors on the yield of bioethanol. The optimization of ethanol was investigated in this study under the following conditions: acid concentration (0.5-2.5 %w/w), hydrolysis temperature (100-130 °C), hydrolysis time (10-50 minutes) and fermentation time (2-6 days). It was observed from the statistical analysis that the maximum ethanol yield of 24.85 % (g/L) was obtained at optimum acid hydrolysis of acid concentration 2.0 %w/w, Hydrolysis time 40 minutes, Hydrolysis temperature 122.50 °C, and Fermentation time 5 days.

This study was undertaken to measure the impact of fertilizers (nitrogen-potassium) on plantain fruits during ripening. Based on nitrogen and potassium content, different doses of fertilizers (T2, T3, T4, T5 and T6) were applied to two hybrid varieties (PITA 3 and FHIA 21) and a traditional variety (CORNE 1) on an experimental split plot plan with a planting density of 2500 plants per hectare. Results showed that total soluble solids (from 0.1° to 1.9 – hybrids and 2.14 – CORNE 1) and moisture content (PITA 3: 67.64 ± 0.06% – 74.63 ± 1.02%; FHIA 21: 67.81 ± 0.89% – 72.19 ± 2.10% and CORNE 1: 61.71 ± 0.23% - 67.78 ± 1.11%) increased significantly during ripening, while firmness (33.93 ± 1.00 N – 1.78 ± 0.76 N), pH (22.90 ± 1.01% - 24.18 ± 2.00%) and hue angle values for peel (27.03% - 31.02%) and pulp (0.05% - 3.66%) decreased considerably. Fruit grown without fertilizer T1 had the lowest moisture (PITA 3: 65.07 ± 1.09% - 68.08 ± 2.00%; FHIA 21: 65.35 ± 3.09% - 69.95 ± 0.09% and CORNE 1: 59.00 ± 1.23% - 65.15 ± 0.67%) content and firmness reducing (72.83 ± 0.24% PITA 3 and 79.49 ± 1.87% CORNE 1). In contrast, PITA 3 (92.14 ± 2.01%) and CORNE 1 (86.84 ± 1.03%) fruits from T4 treatment with high nitrogen content (360 kg/ha) had the highest firmness drop at yellow stage of ripening. Firmness of hybrid PITA 3 and FHIA 21 yellow fruits were twice (3.22 ± 0.03 N; 3.08 ± 0.12 N) smaller than CORNE 1 fruits (7.74 ± 1.02 N). The CORNE 1 fruits were the least humid and the firmer.

Authors: Benjamin U Ebeshi  , Samuel J Bunu  , Hilda F Kpun  , Cynthia O Ezebube
Published: May 2022

In dyspepsia, formulations known as antacids are regularly used to alleviate symptoms as quickly as possible. Gastric contents are acidic; therefore, antacids are usually weak bases with the potential to neutralize excess acid and raise gastric pH accordingly. Acid-neutralizing capacity is what determines the effectiveness of an antacid. Some antacid tablets formulation from different manufacturers were tested for their acid-neutralizing capacity and effectiveness for patients in this study. The South-East region of Nigeria had pharmacies vending antacids of different brands. To remove potential bias from the study, the brands were coded A-F. Labels on all samples indicated that they would expire more than one year from now. To determine each antacid tablet's acid-neutralizing capacity, the titrimetric method was used. In terms of acid-neutralizing capacity, brands D, A, B, C, F, and E showed the greatest acid-neutralizing capacity (8.2mEq/g), and brand E showed the lowest capacity (5.7 mEq/g). An analysis of the ANC of all the tablets found that they exceeded the FDA standard of >5mEq for antacids. An inexpensive, simple, and easy-to-use titrimetric method could be used routinely to monitor antacid tablet quality.

Published: May 2022

The aim of this study was to identify the Propoxazepam metabolites, formed by suspension of rat, dog, monkey and minipig cryopreserved hepatocytes. A suitable chromatographic method was developed for the profiling of Propoxazepam and its metabolites. Samples were analyzed using a Waters Vion high resolution LC-MS/MS instrument and data examined using Waters Unifi software to determine the identity of the most abundant metabolites. The reported proportions of parent compound and its metabolites assume equivalent mass spectrometer detector response. The proportions of unchanged parent drug after 4 hour incubation with hepatocytes varied between 37.1 to 96.0 % of the total peak response. The most abundant metabolite observed across all species was oxidised Propoxazepam (3-hydroxy derivative) which accounted for between 2.5 to 46.5 % of the total peak response in the 4 hour samples. Four other minor metabolites were observed each representing <10 % of the total peak response. The primary route of in vitro metabolism was by oxidation, dealkylation and conjugation with glucuronic acid. Some species differences were noted. The presented data indicate the absence of reactive chemicals among the metabolites of Propoxazepam. Propoxazepam underwent moderate metabolism in monkey cryopreserved hepatocytes after 4 hour incubation. Less extensive metabolism was observed in rat and minipig hepatocytes after the same incubation period and limited metabolism was observed in dog hepatocytes.
