Challenges and barriers to connecting World Class Manufacturing and continuous improvement processes to Industry 4.0 paradigms
Authors: Terra José Daniel Rodrigues , Berssaneti Fernando Tobal , Quintanilha José Alberto
Published: February 2022

This paper exposes the difficulties in integrating “Industry 4.0 Practices” and “World-Class Manufacturing” due to the rapid expansion of production systems and the increasingly complex data monitoring. The applied methodology was to study multiple cases with the aid of a semi-structured questionnaire. The analysis comprised responses of 15 large companies with different expertise from five countries and three continents. The results show that when a company’s strategy is linked to Industry 4.0 practices and the World-Class Manufacturing method, they boost productivity by monitoring the shop floor, applying analytical tools, and spreading the organisational culture aimed at improving processes. The results also indicate that human resources are essential in this integration. The conclusion indicates robust barriers to the increasing progress of these procedures, such as the costs associated with the use of technologies, the lack of knowledge of the applied methods and tools, the lack of trained and qualified human resources, and the resistance of people to the use and application of the newly adopted practices. The continuous improvement practices do not keep up with the speed of development that the Industry 4.0 practices propose, requiring studies directed to “World-Class Manufacturing” and “Industry 4.0 practices”. Although there is a coexistence of improvement and innovation in world-class manufacturers, the literature has not yet provided a complete understanding of how this coexistence can be achieved at the manufacturing level. Therefore, the paper presents the main actions to overcome these barriers.

Published: February 2022

Reducing the quantities of food lost or wasted will be an emerging challenge in coming years. The sector contributing the most to food waste is households. The aim of this study is to evaluate consumer behavior on the food market in the context of wastage identification and assessment of consumer opinions in Poland regarding the causes of the problem of food waste in households. A quantitative study was carried out using individual direct questionnaire interviews (N = 1,145). Results showed that Polish consumer opinions regarding reasons for wasting food vary according to demographic and economic conditions. The least educated consumers and families with several children were found to be guided by economic premises in their purchases more often than other groups and plan their purchases more rationally. The causes of food wastage related to irrational behavior were more often named by consumers with higher standards of living and by the younger generation.

Energy Efficiency in the Romanian Industry
Authors: CLODNIȚCHI Roxana
Published: February 2022

Romania's energy intensity is almost double compared to the EU average. The country is the sixth most energy-intensive country in the EU-28 and there is a great need for energy efficiency in all economic sectors. Energy efficiency represented a significant part of each of Romania’s energy strategies over the past decades. In order to achieve the goals set out here, many measures have been taken to increase efficiency in all areas of the country's economy. Economic growth has apparently decoupled from energy consumption. However, this fact can be rather explained due to the structural change of the economy towards tertiarization and low energy intensity industries. The present article presents a critical overview of the development of Romania and it’s economic sectors with regard to their energy intensity. It addresses both economic and political and legal frameworks, with a focus on energy policy. Special attention will be given to industry, with a focus on energy-intensive industrial sectors.

The effects of designed protection conditions such as different antioxidants (propyl gallate, PG and Pyrogallol, PY), antioxidant concentration (30 – 600 ppm), temperature (30˚C -120˚C) and storage period (3 – 5 days) on the oxidation stability of castor biodiesel were investigated work was to assess the effect of the antioxidants on the oxidative stability of castor biodiesel. Using the American Standard for Testing Materials (ASTM) recommended protocols to determine the changes in the physicochemical properties (acid value, p-anisidine value, peroxide value, totox value, density, kinematic viscosity and refractive index) of the castor biodiesel were measured. The protection conditions were optimized using the Response Surface Methodology (RSM) according to the Box–Behnken Design (Design Expert version 11 Statistical Software). The analysis of variance (ANOVA) of propyl gallate showed concentration levels and temperature as the most important factors in the biodiesel oxidation, whereas the day of storage was one of the lowest factors with the p-value of < 0.05 for most indicated process variables of both linear and quadratic model terms were significant. The changes in some important physicochemical values are indication of degradation occurring in the biodiesel under the set storage condition. The optimal storage conditions were observed in propygallol with the acid value (0.985 mg KOH/g), p-anisidine value (7.650 mg KOH/g) and Totox value 4.005 (mEq/kg) with the overall desirability of 0.923 based on comparatively lower acid, p-anisidine and Totox values, followed by PG. The combined use of PY/PG antioxidants didn't show a synergic or additive result that makes the mixture of those antioxidants unsuitable to boost the biodiesel stability based on their relatively higher Totox Value.

Published: February 2022

The purpose of this study was to determine the characteristics of the fly ash catalyst and to test the catalyst in the production of biofuels from used cooking oil. Fly ash catalyst which has been activated using 1M NaoH was analyzed using XRD at an angle of 2θ = 15° - 80° with a wavelength (λ) of X-rays of 0.15406 nm. From the results of the analysis, the compound NaO26Si6Y9 was obtained with a hexagonal structure. Furthermore, the results of the XRD analysis that can be obtained in the form of wavelength, intensity, 2θ and FWHM values will be substituted into the Debye Scherrer Equation to calculate the crystal structure size of the Fly Ash catalyst. So that obtained Crystal Size (D) of 8.1942 nm. Crystal size is an important factor for the catalyst because it is related to the number of active catalyst sites and the surface area of the catalyst. In addition, the larger the crystal size, the greater the surface area of the catalyst so that the greater the surface energy it has. In testing the fly ash catalyst in the process of cracking used cooking oil into biofuel, the optimum condition of the catalyst was 10% and the volume of biofuel produced was 615 mL.

Lymphocele is a lymphocyte-rich fluid collection that results from disruption of lymphatics in the recipient during renal transplantation. While small collections resolve spontaneously, larger, symptomatic ones may cause obstructive nephropathy requiring percutaneous or laparoscopic drainage. Prompt diagnosis using bedside sonography may obviate the need for renal replacement therapy. Herein, we present a case of a 72-year-old kidney transplant recipient who developed allograft hydronephrosis secondary to compression by a lymphocele.

Authors: Blau Ira , Besharatian Behdad , Reisinger Nathaniel
Published: February 2022

A radiographic incidental finding (sometimes called an incidentaloma) is defined as a structure that is unintentionally found during an exam for an unrelated indication. The increased use of routine abdominal imaging is associated with a rising incidence in incidentalomas of the kidney [1]. In one meta-analysis, 75% of renal incidentalomas were benign [2]. However, the overall prevalence of incidental carcinomas is low at 0.2% [3]. With the growing uptake of POCUS, healthy volunteers for clinical demonstrations may find themselves with new findings despite a lack of symptoms [4]. Having an incidentaloma discovered during the course of a nephrology POCUS workshop is a unique experience. Herein we report our experiences of having incidentalomas discovered during the course of POCUS demonstrations.

Published: February 2022

63-year-old man with past history of multiple myeloma recently started on a regimen of daratumumab, carfilzomib, and dexamethasone was referred to our emergency department for a rapidly rising serum creatinine as high as 10 mg/dL. He complained of fatigue, nausea, and poor appetite. Exam revealed hypertension, but no edema or rales. Labs were consistent with AKI without hypercalcemia or evidence of hemolysis or tumor lysis. Urinalysis and urine sediment were bland without proteinuria, hematuria, or pyuria. Initial concern was for hypovolemia or myeloma cast nephropathy. POCUS revealed no overt evidence of volume overload or depletion, instead revealing bilateral hydronephrosis. Bilateral percutaneous nephrostomies were placed with resolution of the AKI. Ultimately, referral imaging revealed interval progression of bulky retroperitoneal extramedullary plasmacytomas compressing the ureters bilaterally related to the underlying multiple myeloma.

Published: February 2022

Acute kidney injury (AKI) is recognized as a complication of COVID-19 among hospitalized patients. Lung ultrasonography (LUS) can be a useful tool in the management of COVID-19 pneumonia when interpreted correctly. However, the role of LUS in management of severe AKI in the setting of COVID-19 remains to be defined. We report a 61-year-old male who was hospitalized with acute respiratory failure from COVID-19 pneumonia. In addition to requiring invasive mechanical ventilation, our patient developed AKI and severe hyperkalemia requiring urgent dialytic therapy during his hospital stay. Our patient remained dialysis dependent despite subsequent recovery of lung function. Three days following discontinuation of mechanical ventilation, our patient developed a hypotensive episode during his maintenance hemodialysis treatment. A point of care LUS performed soon after the intradialytic hypotensive episode found no extravascular lung water. Hemodialysis was discontinued and the patient was initiated on intravenous fluids for one week. AKI subsequently resolved. We consider LUS an important tool in identifying COVID-19 patients that would benefit from intravenous fluids following recovery of lung function.

Published: February 2022

To analyze vibration parameters of the pipeline (displacement amplitudes, internal forces, and support reactions) the model, algorithm, and program were created. The model is a quasi-one-dimensional (quasi-1D) finite element system. The calculation algorithm is based on the discrete version of the partial responses method. Formulas for partial responses and partial parameters necessary for the implementation of the proposed algorithm were derived. The influence of the flowing liquid is compensated by applying an additional inertial load, which, in turn, is taken into account by correcting and modifying the inertia-stiffness characteristics of the pipeline model. The problem of the vibration of a straight pipeline of a constant cross-section with two points of support is given as an example. The influence of inertial load components on vibration parameters, own frequency values, and the critical velocity of the liquid were studied. The convergence of the process in case of using method of successive approximations was estimated.

Under operating conditions, the main engine and the fixed pitch propeller are interdependent, and their parameters are interrelated. Main low-speed engines, as a rule, have significant cylinder power and are used on vessels characterized by significant coefficients of the hull volumetric completeness. With the stationarity of the operating factors, the vessel's speed is directly proportional to the propeller rotational speed. Thus we can talk about the self-similarity of the hull resistance characteristics and the propeller resistance moment. Analysis of the results of operational tests of heavy-tonnage vessels showed the deviation of the parabola coefficient of the propeller characteristic from the characteristic values. An increase in the error in assessing and predicting the heat load of an engine operating according to propeller characteristics can contribute to a decrease in the reliability of the main power plant. In the article, based on the operational test data, the indicators of interaction between the main engine, the vessel's hull and the propeller are analyzed in terms of the parameters of the equations of propeller and running characteristics. To verify the data, a mathematical model of the TRANSAS Engine Room System simulator was used. Based on the data obtained, it was agreed that adjustments of the mathematical description of the propeller characteristics should be made during the preparation of the vessel acceptance tests and the engines heat load control during operation.

Description du sujet. L’érosion hydrique est une problématique particulièrement importante, notamment dans la zone méditerranéenne et semi-aride. Cette zone est caractérisée par des régimes pluviométriques irréguliers qui ont une influence considérable sur les pertes en sol. Dans les zones montagneuses, les phénomènes d’érosion hydrique sont accentués par les fortes pentes et la couverture réduite du sol. Les barrages alimentés par ces zones subissent un envasement lié à une érosion importante. L’envasement de ces barrages limite drastiquement leur capacité et donc leur durée d’exploitation. Lorsqu’ils sont utilisés pour la recharge de nappes phréatiques, les lâchers entrainent la remise en suspension des particules fines qui s’accumulent au niveau des zones de recharge et réduisent la capacité d’infiltration par colmatage de la porosité du sol, ce qui conduit à un abattement important des niveaux piézométriques. De plus, les nappes phréatiques situées dans la zone côtière sont sujettes à des pompages intensifs. Ces deux phénomènes ont pour conséquence de rendre les nappes particulièrement sensibles aux intrusions marines. Objectifs. Cet article vise, d’une part, à quantifier le taux d’envasement dans le cas du barrage de Boukourdane (Nord de l’Algérie), qui est utilisé pour la recharge des nappes phréatiques et à montrer, d’autre part, la diminution de la perméabilité au niveau du champ captant avec la gestion actuelle des lâchers. Méthode. Les débits solides ont été mis relation avec les débits liquides et la concentration en sédiments prélevés ponctuellement dans l’oued. La relation établie a permis d’évaluer les apports solides dans le barrage de Boukourdane. L’impact des lâchers sur la recharge du champ captant a été évalué par regroupement des puits et forages du champ captant à l’aide de l’heuristique k-moyenne. Des régressions ont ensuite été appliquées sur les variations piézométriques de chacun des groupes. Résultats. Le taux d’érosion spécifique des sols, aussi appelé taux de dégradation spécifique des sols, a été évalué à 366 t·km-2·an-1 pour la période de 1993 à 2005. L’augmentation de la fréquence des pluies exceptionnelles se traduit par une augmentation du taux d’érosion des sols à 446 t·km-2·an-1 (+ 22 %) pour la période de 1993 à 2013. Ces valeurs correspondent à des volumes de vase accumulés au droit du barrage respectivement de 8·104 m³·an-1 et 11·104 m³·an-1. Conclusions. Une modification de la gestion des lâchers actuelle a un impact positif sur la restauration partielle de la conductivité hydraulique et de facto, sur la lutte contre les intrusions marines.

Description of the subject. Quercus rubra L. is considered an invasive species in several European countries. However, little is known about its dispersal in the introduced range. Objectives. We investigated the significance of animal dispersal of Q. rubra acorns on the ground by vertebrates in its introduced range, and identified the animal species involved. Method. During two consecutive autumns, the removal of acorns from Q. rubra and from a native oak was assessed weekly in forest sites in Belgium. We used automated detection camera traps to identify the animals that removed acorns. Results. Quercus rubra acorns were removed by wood mice (Apodemus sylvaticus L.), red squirrels (Sciurus vulgaris L.), rats (Rattus sp.), and wild boars (Sus scrofa L.). The two former are scatter-hoarding rodents and can be considered potential dispersers. Conclusions. Dispersal of Q. rubra acorns in Western Europe by scatter-hoarding animals may help the species increasingly colonize forest ecosystems.

Published: February 2022

Introduction. With increasing herd sizes and decreasing workforce availability, precision livestock farming (PLF) is being developed in the dairy sector to facilitate herd monitoring. A desire to reduce the drudgery of repetitive tasks is another factor contributing to the adoption of PLF. This study, based on a review of the scientific literature, focuses on the impact of PLF on the profession and work organization of dairy farmers. Literature. Time savings are observed because robots and sensors take on recurrent physical tasks (milking, feeding) while simplifying the monitoring of animals (heat, health problems, etc.). Farmers appreciate the additional flexibility in organizing their work. The information provided can reduce the mental workload due to the anticipation of events (insemination, health problems). However, the mental workload can sometimes be increased due to the complexity of the information involved in managing the multiple alarms or alerts and equipment failures. The relationship between farmers and their animals is also modified.

Published: February 2022

Description of the subject. Edible mushrooms cultivation is one of the most important agro-industries in Mexico, showing good impact on food production through a controlled biotechnological process. National production is supported by foreign strains although this region has a great biological diversity in wild mushrooms species with adaptatively advantages to the local environment, but these genetic resources have been few studied, especially for Agaricus species. Objectives. To unravel the potential of wild Mexican strains of Agaricus bisporus for the production of fruiting bodies on compost. Method. The mycelial growth rate of eight A. bisporus strains (two wild, six commercial) in culture media was assessed by supplementing a malt extract medium with yeast extract (YMEA), yeast extract and indulin AT (YMEA-indulin AT), and compost extract (CMEA) at three different incubation temperatures (22, 25 and 28 °C). Mycelial growth was evaluated in solid media (mm·day-1) and liquid culture (decrease in the phenol content). Four strains (two wild, two commercial) with the best in vitro results were selected to obtain carpophores on compost and evaluate their yields. Results. The highest values of mycelial growth were observed in CMEA and the greatest decrease in phenol content was recorded for YME. Biological efficiencies of the four selected strains were 50.8 to 95.5%, and yields were 7.4 to 14.1 kg·m-2 in crop cycles of 74 to 98 days. Basidiomes 5 to 15 cm in diameter predominated. Conclusions. The characteristics of the wild strains indicate their suitability for the regional market, but additional experiments are necessary to improve their productivity parameters.
Development of PCR screening assays focused on gene-coding sequences for GMO detection

Published: February 2022

Description of the subject. This paper describes the development, evaluation and limitations of screening PCR assays based on genes and for use in GMO detection. Objectives. The aim of this research is to propose new PCR assays based on gene-coding sequences that will join a panel of existing screening assays to make better GMO detection possible. Method. Real-time PCR methods using double-dye probes were developed for genes frequently encountered in GM constructs and evaluated in terms of specificity and sensitivity. Results. Eight real-time PCR tests were designed based on the sequences of the bar, pat, EPSPS, gox, gus and hsp70 genes. Two of them proved of limited interest due to the presence of positive signals linked to the presence of the donor organisms: residual sequences of Escherichia coli in the master mixes for the gus PCR assay and while for the hsp70 PCR test, hsp70 being only used in GM maize at present, it is useless as hsp70 originates from maize. The assays for bar, pat, EPSPS and gox were found to successfully detect the corresponding structural elements introduced in GM constructs. Several PCR assays were proposed for the EPSPS gene in order to cover the different versions of the gene. Conclusions. Real-time PCR tests for bar, pat, EPSPS and gox were developed and met the expected performance criteria in terms of specificity and sensitivity. The targets can be amplified with the same PCR conditions as PCR assays already developed for the detection of promoters and terminators, and can be used in combination on the same PCR plate in order to provide wider coverage of GMOs and initial information concerning the GMO(s) present.
New Trends in the Social and Solidarity Economy Regarding Agriculture and Food
Authors: Perrin Antoine
Published: February 2022

On the question of food and livelihood, international institutions and States call for efforts towards food security under the form of help in subsidies or better access to the market for farmers. Such efforts rely on large scale solutions and make food security depend on tall vertical institutions aiming at bringing change in a very large area at a time. On the other hand, small initiatives are born everywhere and take up on the question of access to healthy sustainable food. Farmers’ self-help groups, shared gardens, community supported agriculture, cooperative supermarket and other organisations make up this landscape and are being born everywhere. Such initiatives are often missed by observers as case studies of single organisations can not bring into light the global effort of such initiatives. Nevertheless, they can be put together and showed as being part of the same global movement. If their juridic forms, organisations, and goals are somewhat different, some trends can be established in the justification they offer to their action (Boltanski, Thévenot, 1991). In order to discover these justifications and establish trends, a study of the discourse and practices of such initiatives is offered in the following article. Namely, our study takes 20 initiatives dealing with agriculture and food. In order to find out trends, this article elaborates on the fieldwork of about 500 hours spent within said initiatives, and 50 interviews with project planners, coordinators, and motnitors. In order to show global trends, these initiatives have been chosen in two vastly different social and economic contexts: one takes place in Nancy, a medium French town, the other takes place in Ahmedabad, a very large Indian city. The results of the study show three major common trends between France and India, and between initiatives pertaining with small farmers, shared gardens, cooperatives and other social and solidarity initiatives. Firstly, there is a general call for localized, short food circuits, namely producers and consumers ask for a direct connection to each other, and even to grow the food they eat and eat the food they grow. Secondly, participants in said initiatives do not claim to be part of a recent innovative wave, but rather fall back on traditional ways to grow, sell, and cook food. Thirdly, despite the small size of such initiatives – with 200 participants at most and sometimes as small as 2 members – the ambition of these organisations is to change things on a global scale, make people from every path of life ask themselves questions and change their behaviour, and even, struggle against global climate change through small localized actions.
