Analysis of the Handle Cross-section Design of Cordless Drill Screwdriver
Authors: Jhe Li Hao , Chang Johan
Published: June 2023

The "cordless drill screwdriver" is a widely utilized and versatile tool in the field of power tools. However, power tools generate a certain amount of torque force transmitted to the hands during operation. While the human wrist joint can absorb a certain degree of torque force, the torque generated by power tools during handheld operation is significant, leading to deviations in wrist posture and forearm rotation, which also impose muscular load. Previous studies have proposed diameter recommendations for cylindrical handle designs to enhance performance and reduce the risk of muscle load. It has been suggested in past research that the diameter of a circular handle affects grip strength, and recent studies have used hand handles scanned with magnetic resonance imaging to increase the contact area between the hand and the handle, improving grip contact force and comfort. It is evident that the size and form of the handle significantly impact the operator's grip strength, efficiency, and subjective perception. Building upon this, this study aims to explore the drill-driver configurations that reduce reverse torque. We will collect and compile various handle cross-sectional designs of cordless drill screwdrivers available on the market, using an affinity diagram to categorize the existing handle cross-sectional designs. The results reveal a total of six major handle cross-sectional designs in the market. Furthermore, the grip postures corresponding to these six-handle cross-sectional designs will be discussed, and future experiments can be conducted to investigate the impact of these six-handle cross-sectional designs on grip strength.
Dynamic control assignment and automated risk assessment for external control interfaces in the operating room based on ISO IEEE 11073 SDC
Authors: Wickel Noah , Yilmaz Okan , Radermacher Klaus , Janß Armin
Published: June 2023

Surgical procedures require a variety of medical devices, each bearing an ever-increasing number of settings and functions. Most devices are placed in the unsterile area of the operating room. Therefore, the surgeon and other sterile staff members are not able to interact with the device interfaces. Surgeons often rely on so-called ‘yell-and-click communication’ to have a setting changed, which is error-prone, slow and moreover leads to process interruptions for the involved OR personnel. Suitable control devices, like a foot switch or a sterile user interface, can allow sterile staff members direct access to certain device functions. In a networked operating room, such control devices could exist for any controllable value or operation. Due to spatial limitations in the OR, it is desired to use as few physical control devices as possible. To control a large variety of parameters, these control devices' associated functionality could be re-assigned during a surgical procedure. The manufacturer-independent communication standard ISO IEEE 11073 SDC is tailored for medical device control in the operating room and makes such a re-assignable control interface technically feasible.However, each control association must be assessed with regard to its usability and risk management. For example, a critical control target must never be controlled by an element which is too coarse for the intended task. Therefore, it is a key requirement to develop a software model for control devices and a mechanism to allow or deny a proposed mapping desired by the user based on safety and usability criteria.In the present work, we outline a system to describe and categorize input devices (control elements such as buttons, knobs and foot switches) and controllable counterparts (Targets) typically found in the surgical context. Great attention is given to the means necessary to safely control critical parameters. We assess the current descriptive capabilities of SDC and propose necessary additions to create more comprehensible software models of the control devices. Finally, we present a new convention for medical device modeling which could be used to propose or prohibit unsafe or unintended mappings in a user interface for configuring control devices in the operating room.

Published: June 2023

In the context of the Brazilian electrical sector, there are no references regarding the application of BIM (Building Information Modeling) and GIS (Geographic Information System) in construction and maintenance of Electric Power Substations. Thus, this work proposes the integration of these technologies, since previous experiences in other engineering fields have shown promising advances that could be useful for the management and maintenance of the electrical power market. By associating these technologies, it is possible to obtain a more accurate mapping of the information related to the assets, arrangements, cabling, electronic components, etc. Moreover, in order to have this integration working properly, it is required to also provide a three-dimensional geometric database of the entire set of the electric power substation active components. In fact, the insertion of one model into a particular point of the substation project allows constructive, operational and maintenance information. Therefore, by combining BIM and GIS in the modeled families, it is possible to obtain more consistent information during the construction or maintenance phase. This will provide advantages in decision making, resources within the corporate communication and a better understanding of the environment related to an electrical energy substation. Additionally, the location conditions and the surroundings of the substation would be more precise and pertinent since the components of the substation will become geo-referenced. The association between these two platforms allows a more intuitive overview of the project, making them adherent to the planning, design, construction, operation, preventive and corrective maintenance. So, when applying these tools together, the company will obtain results almost immediately, since all managing features will be accessed through only one integrated information database. This proposal presents the very first results of the integration of BIM and GIS, in the context of a Brazilian electric company - Furnas Energy. Implementation results of the solution in the context of substations of the company are discussed and shows the availability of reducing construction/maintenance costs, alteration planning, logistics, prevention of possible accidents and also the possibility of updating information in real time.

Published: June 2023

This study aims to improve sweet potato production in the Philippines by identifying the challenges facing sweet potato farmers and providing effective interventions to address these issues. Participatory Action Research (PAR) was used to foster community participation and action and to establish a baseline profile of farmers, assess participation rates, evaluate interventions using high-yield varieties and proper training on the use of the stem-cutting system and staggered planting, and identify challenges after the intervention. The mean age of the participants was 52.44 years old, indicating that they belong to the marginalized adult group, and their average monthly income from sweet potato production was relatively low. In addition to sweet potato farming, the key informants are also engaged in other crop production, such as rice (100%), banana (89%), cassava (67%), corn (67%), taro (67%) and potato (22%). Regarding fertilizer use in sweet potato farming, key informants use urea and complete 14-14-14 fertilizers. Using NSIC Sp-36 and UPL Sp-17 varieties combined with staggered planting and stem-cutting techniques effectively increases sweet potato yield per hectare. The total yield from the scientific interventions was 8,000 kilograms or 8 tons, twice the target yield of 4,000 kilograms or 4 tons. While the adaptation of the farming strategy effectively increased to 160% actual yield, there is a low market demand due to the lack of production takers, which constrained the success of this intervention. Moreover, some farmers could not attend the activity, which is essential to note. These interventions can potentially improve the productivity of sweet potato farming and increase food security and income for small-scale farmers. However, there is a need to intensify the marketing strategy.

Published: June 2023

The development of RDF-5 fuel from community waste using natural rubber as a binder was investigated. The results showed that the calorific and heat values were increased proportionately to the amount of rubber added. The ratio with the highest calorific value was 50:50, followed by 75:25, 90:10, and 95:5. The calorific value was 40.67 MJ/kg (9720 kcal/kg), 40.24 MJ/kg (9,617 kcal/kg), 39.28 (9,389 kcal/kg) and 39.18 MJ/kg (9,365 kcal/kg), respectively. Compared with 100:0, have a calorific value of 38.84 MJ/kg (9,284 kcal/kg). The experimental addition of natural rubber as a binder makes the combustion process more complete, resulting in faster fuel ignition time or easier igniting, less ash content, and being environmentally friendly. The research team chose to develop the ratio of 95:5 because the economic analysis showed a fast payback period of only 5.72 years. So, the ratio of 95:5 is the optimal condition that can scale up to the industrial level. The production cost of RDF-5 is 1,935 baht/ton for 50 baht/kg of natural rubber. The amount of emission caused by the combustion process of RDF-5 (95:5) passed the standard. Therefore, the evaluation of this research found that RDF-5 fuels from community waste using natural rubber as a binder. It is one of the attractive alternatives to renewable fuel generation and solid waste management solutions and helps improve the environmental quality of communities.

Finite Element Analysis of Notch Depth and Angle in Notch Shear Cutting of Stainless-Steel Sheet
Authors: Engin Kaan Emre
Published: June 2023

Piercing is a crucial process in the sheet metal forming industry, and the surface quality of the pierced part is an important parameter that defines the overall quality of the product. However, obtaining a good surface quality is a challenging task that depends on the effect of several process parameters and necessitates the use of non-conventional procedures. Notch shear cutting is a relatively new progressive approach in which the workpiece is indented with a notch form with a predefined notch angle and depth, and then the indented workpiece is subjected to conventional piercing. In this study, conventional piercing and notch shear cutting processes were experimentally performed on 1.4301 stainless steel sheet of 2 mm thickness. Then, finite element (FE) analyses were conducted utilizing Deform-2D software. After ensuring that the experimental and simulation works were consistent with each other, the FE analysis of notch shear cutting was carried out for three distinct notch depths (15 %, 30 %, and 60 % of the workpiece thickness) and six different notch angles (10º, 20º, 30º, 40º, 50º, and 60º). Investigations were performed on shear zone length distributions, which are direct indications of the surface quality on sheared workpieces, crack propagation angles, and required cutting loads. The best surface quality was obtained when the notch angle was set to 50º and the notch depth was set to 15 % of the workpiece thickness. It was also observed that notch angle and notch depth had a certain level of influence on required cutting load.
Inventory Risk Decision-Making Techniques Using Customer Behaviour Analysis
Authors: Marc Ivan , Berlec Tomaž
Published: June 2023

More recent research shows the significant impact of accurate demand forecasting on the operation of supply chain system and thus on the performance of the company. Inventories in the production process could represent waste, which results in higher storage costs and consequently a higher product price, which in turn reduces company's competitiveness on the market. Nevertheless, a company must implement a lean production process and consequently carefully control storage and inventory costs. The introduction of a lean production process is closely linked to the risk of stock-outs, and knowledge of this risk in relation to customer habits is therefore a useful piece of information for the line manager's decision-making. This paper will present a mathematical model that relates customer demand for a product to the inventory level in the warehouse or between the work operations of the production process and the risk of potential penalties that arises with the introduction of a lean production process. With this model we can simulate, how to improve the production processes with still acceptable risk, with the goal of achieving a balance between stocks and the leanness of the production process. The paper demonstrates the use of a mathematical model on a concrete example from practice for risk simulation when choosing different production scenarios resulting from changed customer behaviour.
The Dynamics of Tapered-roller Bearings – A Bottom-up Validation Study
Authors: Razpotnik Matej , Bischof Thomas , Boltežar Miha
Published: June 2023

Rolling-element bearings are one of the most important elements when predicting the noise of rotating machinery. As a major connecting point between the rotating and non-rotating parts, their dynamic properties have to be accurately known. In this investigation we present a bottom-up approach to characterising the dynamics of the rolling-element bearing. A special test device was designed and built to assess the quality of the well-established analytical modelling approach of Lim and Singh. Two types of bearings were tested, i.e., the ball and tapered-roller types. The dynamic properties were observed by investigating the frequency-response functions. In addition, non-rotating as well as rotating test scenarios were checked. It was shown that the ball bearing model adequately predicts the system’s response, whereas the tapered-roller bearing model requires modifications. These results were further confirmed with a quasi-static load-displacement numerical evaluation, where a full finite-element model serves as the reference.

Published: June 2023

Currently, cell and tissue culture are a key to success for regenerative medicine and the pharmaceutical industry for implementing new therapeutic concepts. Cell culture is a complex process in which cells are grown under controlled conditions. Three-dimensional (3D) scaffolds provide space for cell adhesion and growth in 3D structures. However, in 3D cell culture, the ability to supply nutrients and oxygen, and the simultaneous removal of waste products and metabolites are the limiting factors for cells survival, due to nutrient starvation and metabolite toxicity. Therefore, an in-house 3D rotational bioreactor, for 3D cell culture, was designed, fabricated, and developed based on a chitosan porous scaffold. The 3D rotational bioreactor provides a continuously moving culture medium led to high rates of mass transfer throughout the scaffolds. The rotation speed and duration are programable and provide a continuous free flow during the rotating period. The results demonstrated the potential of an in-house 3D rotational bioreactor for better nutrient supply and waste transfer systems outweighs the conventional cell culture technique.

The argan tree, an endemic species in Morocco, has been exhaustively studied in its southwestern range but neglected in its northeastern territory. Thus, the present study sets as objectives the identification of arbuscular mycorrhizal fungi and the evaluation of the argan tree’s roots’ mycorrhization level in two stations: one in the region of Béni Snassène (Berkane): Jebel Takermine with 7 prospected sites and the other at Jebel Aklim Alkabir with 2 sites. At the first station (Jebel Takermine), the mycorrhizal frequency of Argania spinosa roots varied between 64% and 100% with the root mycorrhizal intensity in the range of 30.77% and 66%. The arbuscular contents are higher at sites 2 (50.46%), 4 (50.33%), 7 (39.44%) and 1 (30.5%) against 18% and 20% at sites 6, 5 and 3. Argan trees from Jbel Aklim Alkbir, exhibited a high mycorrhization frequency and intensity ranging from 88% to 100% and between 39.4% and 73.4% respectively. Regarding arbuscular and vesicular rates, the highest values were associated to the roots of site 1 with 59.3% and 29.4% respectively compared to the lowest rates of 20% and 14% in those of site 2. Spore densities in the rhizosphere of the studied argan trees in the two stations were in the range of 78 and 697 spores/100 g of soil. The identification of isolated mycorrhizal spores revealed the presence of 28 species encompassing 7 genera: Acaulospora, Dentiscutata Claroideoglomus, Funneliformis, Glomus, Rhizophagus, Pacispora, and 5 Families: Glomeraceae (7 species), Acaulosporaceae (10 species), Pacisporaceae (2 species), Claroideoglomeraceae (2 species), Gigasporaceae (1 species).

Published: June 2023

Nerium oleander var. ‘Villa Romaine’, commonly called oleander, is an ornamental shrub that exists in Tunisia in the wild and cultivated form. This plant is frequently propagated and produced in nurseries and used in urban plantings and on roadsides. The effects of nature of the plants (spontaneous or cultivated), climatic conditions (localities), and altitude (from 6 to 447 m) on seed shape, size, and germination of Tunisian populations, were investigated. Seeds were harvested from 23 locations belonging to six bioclimatic stages and distributed from North to South of Tunisia. The seed parameters studied were area, roundness, J index, and germination rate. A significant variation was obtained between populations, categories (cultivated and spontaneous), bioclimatic zones and altitudes. Seeds of cultivated plants were the smaller and showed the higher germination rates, compared with spontaneous populations, which had large seeds and a low germination rate. Climatic conditions and geographical location had an effect on seed morphology; seeds in lower humid were small for both cultivated and spontaneous types, they also showed a low J index value and a high germination rate. On the other hand, in upper Saharan, seeds were large and roundness and germination rate were the lowest. Also, seeds from plants in higher altitudes were the smaller and presented the lower values of the J index compared with those collected from low-altitude sites.

Published: June 2023

The study was performed to investigate the possible neuroprotective role of palmatine, a protoberberine alkaloid against aluminum-induced aberration in neurotransmitter levels, excitotoxicity, neuronal inflammation, damage, and degeneration. 100 mg/kg of aluminum chloride served as the inducing agent and was administered orally to male Wistar albino rats for 42 consecutive days. Animals were divided into four groups, groups I, II, III, and IV which involve the normal group, the toxic control group receiving aluminum chloride, and two treatment groups administered orally with palmatine at a dose of 10 mg/kg and 20 mg/kg respectively followed by aluminum chloride. Expression of neuronal inflammatory markers like IL-6 and TNF- α were checked by the ELISA method. Deranged neurotransmitter levels of acetylcholine esterase and glutamate in rat brains were measured to determine the extent of excitotoxicity. The neuroprotective role of palmatine was determined based on histopathological studies and by determining BDNF expression by the immunohistochemistry method in rat brains. Palmatine treatment effectively regulated acetylcholinesterase levels and glutamate levels otherwise elevated by aluminum. It lowered excitotoxic damage induced by aluminum and lowered the degree of expression of inflammatory markers IL-6 and TNF- α. Improved expression of BDNF in palmatine-treated groups is indicative of the neuroprotective potential of palmatine in the restoration of neuroplasticity. Histopathology further confirms the neuroprotective potential of palmatine as the treatment significantly prevented neuronal damage degeneration and loss and restored healthy and viable neurons. The findings of the study confirm the neuroprotective potential of palmatine against aluminum-induced neuroinflammation and excitotoxicity.

Enterococcus faecium is emerging as an important cause of multidrug resistance and hospital acquired infections, special attention being paid to the vancomycin resistant species. Therefore, the characterization of pathogenic strains/isolates plays an important role in the epidemiology of infectious diseases. The enterococcal rate was determined from wastewaters in Cluj-Napoca area. As presence of E. faecium was detected, a number of isolates from wastewater, birds and humans were epidemiologically analyzed according to the MLST website. Comparisons were performed against a collection of available isolates, with multiple origins, contained in the MLST database. Out of the Enterococcus isolates collected from wastewater, 11 were identified as E. faecalis (40.74%); 8 as E. casseliflavus (29.62%); 5 as E. faecium (18.50%); 2 as E. gallinarum (7.40%) and one isolate as E. durans. Based on the MLST data and using the eBURST algorithm, the isolates of E. faecium sampled from Romania were split in three groups: one group comprised isolates from human hosts and wastewater (Cj316, 106/6, Cj197, Cj22, 129/6, Cj117, Cj24, 284/7, and 43/7), while the second (G9, G10-2, G7, G3-2, and G9-1) and the third group (G8, G6, and 40/7) originated from bird hosts. The rest of the isolates were not joined in a particular group, assuming the lack of a phylogenetic bond between these isolates. The obtained data suggested the existence of at least two phylogenetic lines of E. faecium in Romania: a line that had mainly human host prevalence, while in the other line the animal hosts dominated.

A educação superior, vista como simples investimento, é, atualmente, um espaço em disputa, tanto pela sua função social, quanto pelo potencial de lucros que ela pode gerar ao ser explorada como um negócio como qualquer outro. Uma concepção de educação que negue essa mercantilização se faz necessária. Para tanto, o presente trabalho reflete sobre as contribuições pedagógicas de Paulo Freire, entendendo estas como um ponto de partida para uma práxis libertadora na universidade, lançando mão do estudo bibliográfico para apresentar o contraste entre a universidade moldada pelo neoliberalismo e uma universidade voltada para as demandas dos oprimidos.

O objetivo desse estudo consiste em analisar as práticas de sustentabilidade das agências da Regional de uma cooperativa de crédito. Assim, a relevância deste estudo se dá pela necessidade da Cooperativa em ter conhecimento de dados específicos da região contemplada, não percebidos no relatório geral da Cooperativa, como ponto de partida para a estruturação de seu próprio Relatório de Sustentabilidade. Para isso, utilizou-se do referencial teórico pautado na sustentabilidade e no relatório de sustentabilidade. No caminho metodológico foi realizado um levantamento de dados por meio de questionário estruturado, por entrevistas semiestrutura e a pesquisa de documentos. Assim, a análise foi realizada a partir de uma perspectiva mista sequencial, quantitativa na primeira etapa e qualitativa na segunda etapa. Os resultados quantitativos indicam que a dimensão econômica ainda é percebida de forma mais contundente que as dimensões ambiental e social. Outra constatação se deu na separação dos respondentes pela Análise de Cluster, indica que um grupo pequeno percebe de forma menos contundente as dimensões, em especial a dimensão ambiental. E, na análise qualitativa também sobressai da necessidade de melhoria das ações na dimensão ambiental. Em vista disso, os resultados confirmam a viabilidade e necessidade de um Relatório de Sustentabilidade para a Regional. E estes resultados, foram apresentados ao Comitê de Sustentabilidade da Regional, inclusive com um diagrama de etapas para a sua construção.

A qualidade final das mudas de espécies florestais depende de fatores como a manutenção adequada da umidade dos substratos e sua composição física e química, que é favorecido quando da adição de biochar e hidrogel. O objetivo do trabalho foi avaliar o efeito da combinação de biochar com o hidrogel na qualidade de mudas de Enterolobium contortisiliquum (Vell.) Morong. (Tamboril).  Foi utilizado embalagens com volume útil de 2,5 L, contendo Latossolo Vermelho Amarelo (LVA) e ¼ v/v de esterco bovino. O delineamento experimental foi em blocos casualizados, em esquema fatorial 5 x 5, sendo quatro dosagens de biochar de lodo de esgoto (2, 4, 6 e 8% base volume – v/v) e quatro de hidrogel (1, 2, 3 e 4 g L-1 de substrato) e 1 tratamento testemunha para cada fator, com 6 repetições. Avaliou-se a altura da parte aérea (AP), diâmetro do coleto (DC), número de folhas (NF), massa úmida (MuA) e seca (MsA) da parte aérea, massa úmida (MuR) e seca (MsR) das raízes, massa seca total (MsT), razão entre a massa seca da parte aérea e das raízes (MsA/MsR), índice de qualidade de Dickson (IQD), área foliar (AF) e Razão entre altura das plantas e diâmetro do coleto (RAD). As dosagens de biochar de 6 e 8% v/v, combinado com as dosagens de hidrogel de 3 e 4 g L-1 apresentaram melhores valores dos parâmetros morfológicos. A combinação de biochar e o hidrogel incorporados ao solo enriquecido com esterco bovino é uma alternativa viável para melhor da qualidade das mudas de Tamboril.

Um desafio a ser superado é a inclusão das crianças com necessidades especiais nas aulas de educação física escolar. Este artigo apresenta uma analisar das implicações do desenvolvimento motor e das principais dificuldades pedagógicas intrínsecas ao equilíbrio em surdos. Para a metodologia baseia-se em revisões de literaturas acadêmicas, numa revisão bibliográfica que consiste na procura de referências teóricas para análise do problema de pesquisa e a partir das referências publicadas fazer as contribuições cientificas ao assunto em questão. Conclui-se que,as aulas práticas de educação física contribuem beneficamente no desenvolvimento motor em surdos, com exceção, a ausência de estrutura adequada na escola,a desatenção na formação contínua dos educadores e de uma especialização nas áreas afins e o descumprimento com relação a execução do planejamento pedagógico da escola, são fatores adjacentes que se contextualizados se tornam norteadores no processo de inclusão e no desenvolvimento motor em surdos.
Study on a Solar Heating System with Phase Change Energy Storage in Cold Region
Authors: Zheng Longfeng , You Xueyi
Published: June 2023

Although solar energy is one of the most promising renewable energy sources at present, the access to solar energy is unstable and discontinuous, so more advanced energy storage is needed. This paper designs and studies a phase change material (PCM) solar heating system which integrates heat storage and heat removal. In order to evaluate the system performance under actual operation, an experimental system is built. According to the experimental measurement results of the heat charging process, the COP of the system is between 1 and 5.5, which is higher than that of the general household electric heating system (COP=1). According to the system heat release process, the average temperature of the room without heating system is about 6 ℃ higher than the room temperature, and the room with heating system is also about 6 ℃ higher than the room without heating system. When the outdoor temperature is 5-10 ℃, the minimum temperature of the heating chamber is about 16 ℃, indicating that the heating effect is good. Although the new phase-change material (PCM) solar heating system, which integrates heat storage and heat removal, shows relatively good heating effect, further research is needed on the mass flow rate control strategy of the solar energy collection cycle, the filling quality of the phase-change material and the matching of the heat exchanger structure.
Restrictions on property ownership in national parks due to nature protection - empirical approach
Authors: Dzienis Paweł
Published: June 2023

Nature is an undeniable good that requires protection. The highest form of its protection is the national park. It does not arise and does not function in a vacuum, but in the modern dynamically developing world. Such an observation determines not only the imperative of the need to protect nature, but also the reconciliation of all related interests. The subject of the publication is an empirical analysis of the functioning of the national park institution. The article is a civil study of all national parks established in Poland. It is therefore a collection and presentation of basic data for the civil analysis of this institution of administrative law. It is based on the case law studies conducted for its needs and, above all, on the information obtained on the basis of a prepared list of questions from all national parks and voivodeship offices in Poland, where such special areas have been created. The subject of the analysis are the features and constitutive elements of these areas through the prism of civil law: starting from the territory of the park, features distinguishing this area, through the rules in force in its area (prohibitions), in particular relating to the exercise of property ownership, and ending with ownership claims. In conclusion, you can find an answer to the question of how to reconcile the requirements of modern civil law and economic transactions, sustainable development with nature protection. They are especially important at the stage of creating a park or expanding its territory. The study results are presented in tabular and descriptive form.

The catalog of educational measures provided by law and applied in juvenile proceedings includes, among others, referral to an attendance centre a facility that provides educational, resocialisation, therapeutic, preventive or control measures for minors. The professional guardians/probation officers who organize the work in the centres confirm that the described measure plays an extremely important role in the process of preventing criminal acts and manifestations of demoralization among minors. It is a non-custodial educational measure which plays an extremely important role in the process of resocialization and whose potential is not fully exploited. The aim of the text is to propose legislative changes aimed at giving this form of resocialization influence the character of a sui generis measure, with a broadened catalogue of competences. The analysis is based on the current legislation, as well as on the results of the author's nationwide research conducted in a group of 32 professional probation officers working in probation centres, aimed at recognizing the specificity of work in these institutions.
