Impact of fertigation schema on yield and chemical composition of strawberry (Fragaria×ananassa Duch.)
Authors: Pomyaksheva L. V. , Konovalov S. N.
Published: September 2021

A  frequent fertigation of garden strawberry with solute mineral fertiliser in accord with the plant growth phase allows a more efficient mineral nutrient absorption compared to a single application of larger fertiliser amount. Field studies on medium loam-granulometry sod-podzol soil in fruiting garden strawberry plantations were carried out for three years in the Moscow Region to evaluate the impact of fertigation regimes on strawberry yield and the main nutrient content in soil and plant leaves.  In study setup, the control crop grew with a no-fertiliser drip irrigation, schema 1 included frequent (once in 3 days) mineral fertiliser drip application at 2-3 g/l, schema 2 — 4-6 g/l solution application twice less often (once  in 6 days). Materials and methods. Yield was estimated by weight per plot area unit, plant samples analysed with conventional wet  ashing. Nitrate nitrogen was determined in ionometry, exchangeable ammonium —  in photocolourimetry, mobile phosphorus and potassium specimens — by the Kirsanov’s CINAO-modified method. The article presents registration data, averaged leaf chemical assays and content dynamics of major soil macronutrients over a three-year observation period. Conclusions. A significant increase in three-year total yield was observed with the mineral fertiliser fertigation schema in the Ducat strawberry cultivar; a supraoptimal phosphorus accumulation in leaves of the Rusich cultivar was facilitated by a less frequent application of concentrated fertiliser solution; a maximal nitrogen amount in Ducat leaves was observed with fractional fertigation; in a lower-yield season, concentrated mineral fertiliser fertigation contributed to the increase of mobile phosphorus and potassium specimens in soil in mid growing season. A greater correlation was observed between the soil content of mobile potassium and its uptake by strawberry plants.
Prosopagnosia associated with brain metastasis near the inferior longitudinal fasciculus in the nondominant temporal lobe: illustrative case
Authors: Weiss Hannah K. , Pacione Donato R. , Galetta Steven , Kondziolka Douglas
Published: September 2021

BACKGROUND

Disruptions of the inferior longitudinal fasciculus (ILF) in the nondominant temporal lobe can lead to the rare but significant higher visual-processing disturbance of prosopagnosia. Here, the authors describe a 57-year-old right hand-dominant female with a large breast cancer brain metastasis in the right temporal lobe who underwent resection and subsequent Gamma Knife radiosurgery. She presented with difficulty with facial recognition, but following surgical intervention, the prosopagnosia became more profound.

OBSERVATIONS

Even in nondominant cortex, significant deficits can arise when operating near higher visual-processing centers, including the ILF.

LESSONS

This case highlights the utility of imaging-based tractography obtained from preoperative imaging for resective surgical planning even when operating in areas that do not involve what is traditionally considered elegant areas of the brain. To optimize neurological outcomes in metastatic tumor resection, awareness and diffusion tensor imaging of neighboring, displaced white matter tracts may prevent permanent deficits in higher visual processing.

The Cognitive Operator 4.0
Authors: Thorvald Peter , Fast Berglund Åsa , Romero David
Published: September 2021

While previous Industrial Revolutions have increasingly seen the human as a cog in the system, each step reducing the cognitive content of work, Industry 4.0 contrarily views the human as a knowledge worker putting increased focus on cognitive skills and specialised craftsmanship. The opportunities that technological advancement provide are in abundance and to be able to fully take advantage of them, understanding how humans interact with increasingly complex technology is crucial. The Operator 4.0, a framework of eight plausible scenarios attempting to highlight what Industry 4.0 entails for the human worker, takes advantage of extended reality technology; having real-time access to large amounts of data and information; being physically enhanced using powered exoskeletons or through collaboration with automation; and finally real-time monitoring of operator status and health as well as the possibility to collaborate socially with other agents in the Industrial Internet of Things, Services, and People. Some of these will impose larger cognitive challenges than others and this paper presents and discusses parts of the Operator 4.0 projections that will have implications on cognitive work.

Authors: Newman Callum , Petzing Jon , Goh Yee Mey , Justham Laura
Published: September 2021

Artificial intelligence in computer vision has focused on improving test performance using techniques and architectures related to deep neural networks. However, improvements can also be achieved by carefully selecting the training dataset images. Environmental factors, such as light intensity, affect the image’s appearance and by choosing optimal factor levels the neural network’s performance can improve. However, little research into processes which help identify optimal levels is available. This research presents a case study which uses a process for developing an optimised dataset for training an object detection neural network. Images are gathered under controlled conditions using multiple factors to construct various training datasets. Each dataset is used to train the same neural network and the test performance compared to identify the optimal factors. The opportunity to use synthetic images is introduced, which has many advantages including creating images when real-world images are unavailable, and more easily controlled factors.
Actuator and Process Development for Vibration Assisted Turning of Steel
Authors: Schwarze Martin , Rüger Carlo , Georgi Oliver , Rentzsch Hendrik , Pätzold Holger
Published: September 2021

Due to continuous tool engagement, turning processes tend to form long chips when machining ductile materials. These chip shapes have a negative influence on process performance and productivity. One approach to improve chip breakage is superimposition of vibrations in feed direction of the turning process, which leads to a modulation of uncut chip thickness. In a joint industrial project with Schaeffler Technologies AG & Co. KG, Fraunhofer IWU developed an oscillating actuator for turning. The actuator converts a rotational movement of a drive motor into a translational vibration via an eccentric gear. The tool shank is mounted in solid joint assemblies. With this prototypical system, a cyclic movement of the tool in feed direction can be realized. The typical operating parameters of the actuator is within the range of 1...100 Hz with adjustable vibration amplitudes up to 0.6 mm peak-to-peak. A significant improvement in chip breaking during the machining of steel 1.0503 was shown in cutting tests.
Legal Considerations for Using Digital Twins in Additive Manufacture – A Review of the Literature
Authors: Clementson Jenny , Teng Jason , Wood Paul , Windmill Chris
Published: September 2021

Rapid technological change presents new opportunities and reveals new risks, challenging existing governance arrangements. The fusion of Industry 4.0 technologies combines with Additive Manufacturing (AM) to create new business solutions. Legal issues with AM are well documented, for example Daly[1] explores the interaction of 3D printing with the law, identifying Intellectual Property, Product Liability and Data Privacy as areas of importance. However, this technology fusion has also enabled improved real-time digital representation, monitoring, simulation and control of the physical delivered through applications of Digital Twin. Such Digital Twins are prevalent in manufacturing and in AM can potentially provide assurance that a printed item meets specified requirements. However, additional legal considerations are emerging. This paper illustrates these by examining the attributes of “Digital Twins in Additive Manufacture Use Cases” revealed through literature.

Published: September 2021

Aluminum is one of the most extensively used metal in aerospace industry and other applications due to its corrosion resistance, good machineability excellent mechanical properties and high strength to weight ratio. Machining parameters like number of inserts, depth of cut, cutting speed, feed rate, and cutting tool diameter have considerable impact on production rate, surface finish, energy consumption and sustainable machining. Suitable process parameters during machining and specifically milling process not only leads towards better surface finish but also towards sustainable machining. Aim of machining has always been to produce parts with better surface quality and lower energy consumption. To study the effect of milling parameters on the surface finish, Taguchi L9 array was employed for experimentation. The outcome of each parameter on surface finish has been examined using ANOVA and the most considerable parameters were identified. It has also been observed that the number of inserts significantly influence the surface finish.

Authors: Diala Uchenna , Lu Yiling , Bousbaine Amar
Published: September 2021

One of two major limitations of a vibration energy harvester (VEH), concerns its limited performance due to its confined physical enclosure. The maximum span realizable is attained at a specific excitation level. This excitation level provides the maximum energy harvested by the VEH device. Due to span constraints, VEHs are designed to operate at the maximum span achievable at the maximum excitation level existing within the region of interest. In this study, a constrained optimisation problem (for the VEH) is formulated and investigated. This paper focuses on the analysis, design and optimisation of a nonlinear VEH device.
Reduce, Reuse, Recycle: Visual Re-Representation of Design Engineering Knowledge
Authors: Carey Emily , Culley Steve , Allen Bruce
Published: September 2021

The exponential growth of data and information artefacts in engineering organisations are one of the biggest limitations for engineers reusing design knowledge. Approaches to support efficient information access are critical for design. In this paper, we demonstrate an exemplar “Super Document” principle using knowledge “Reduce, Reuse, Recycle” process. Evidence suggests such recycled representations can reduce the time engineers spend on gathering information from documents by up to 70%. We outline the “Reduce, Reuse, Recycle” approach using empirical studies with in-service aerospace design engineers. We suggest visual representations better record and communicate information for design engineers, resulting in a time saving of 70% per design in document information seeking. The infographic “Super Document” created uses visual re-representation of large knowledge artefacts – reducing a 100-page design document to a single page. An insight into the next steps for this research concludes this paper.
Industry 4.0 Application in Lean Manufacturing – A Systematic Review
Authors: Saad Sameh M. , Bhovar Chandan , Bahadori Ramin , Zhang Hongwei
Published: September 2021

For several years Lean manufacturing has been adopted by industries in improving the operational performance of the firm. However, Lean manufacturing is associated with fixed production sequence and slow responsiveness, which limits its capability of meeting the constantly changing customer demand, product variability & customisation. This can inhibit its adaptability in the digital era. Meanwhile, Industry 4.0 technologies support the mass production of highly customisable products by being modular and flexible. Although Industry 4.0 technologies can meet the demands of the digital era, they are considered as a solution provider with little scope for organisational process improvement. Hence, an integration of both approaches will lead to a competitive advantage in the digital era. This paper aims to explore and evaluate the work done by researchers in identifying the link between lean manufacturing and Industry 4.0 technologies, through a systematic literature review to understand if lean manufacturing and Industry 4.0 technology can be integrated effectively.

Authors: Onyeme Chinedu , Liyanage Kapila
Published: September 2021

The shift towards Industry 4.0 is a fundamental driver of improved changes observed in today’s business organizations. The difficulties in adapting to this new approach pose challenges for many companies especially in the oil and gas (O&G) upstream sector. To make this path much feasible for companies in this industry, Maturity Models (MMs) are very useful tools in achieving this following their use in evaluation of the initial state of a company for planned development journey towards Industry 4.0 (I4.0) readiness and implementation. Study shows that only a limited number of O&G specific roadmaps, MMs, frameworks and readiness assessments are available today. This paper aims to review the currently available Industry 4.0 MMs for manufacturing industries and analyze their applicability in the O&G upstream sector using the systematic literature review (SLR) methodology, recognizing the specific requirements of this industry. The study looks at the key characteristic for O&G sector in relation to the manufacturing sector and identifies research gaps needed to be addressed to successfully support the O&G sector in readiness for Industry 4.0 implementation. An Industry 4.0 maturity model that reflects the industrial realities for the O&G upstream sector more accurately from insights drawn from the reviews of existing MMs is proposed. This reduces the challenges of the transition process towards Industry 4.0 and provides support for the critical change desired for improved efficiency in the sector.

Published: September 2021

Modern cities are changing to become more reliant upon technology for better personal, social, and economic outcomes for all citizens. The core of enabling a smart city plan relies on a comprehensive understanding of its drivers and technological aid requirements. Hence, technology roadmapping as one of the most effective approaches need to be considered to aligning the smart cities strategies with planning in the field of technology, while the focus on the most technology roadmapping studies has been limited to the development of industrial technology and product development. Thus, to support the achievement of the smart cities, this study aims to adapt and utilise Strategic Technology Alignment Roadmapping (STAR) methodology to guid and justify investment in smart city’s R&D projects to achieve the optimum project portfolio. The method is tested in a real case study, which shows how STAR methodology can be effective to implement throughout the worldwide smart cities development to support strategic technology investments.

Authors: Mambrini Francesco , Passarotti Marco , Litta Eleonora , Moretti Giovanni
Published: September 2021

This paper describes the steps taken to model a valency lexicon for Latin (Latin Vallex) according to the principles of the Linked Data paradigm, and to interlink its valency frames with the lexical senses recorded in a manually checked subset of the Latin WordNet. The valency lexicon and the WordNet share lexical entries and are part of the LiLa Knowledge Base, which interlinks multiple linguistic resources for Latin. After describing the overall architecture of LiLa, as well as the structure of the lexical entries of Latin Vallex and Latin WordNet, the paper focuses on how valency frames have been modeled in LiLa, in line with a submodule of the Predicate Model for Ontologies (PreMOn) specifically created for the representation of grammatical valency. A mapping of the valency frames and the WordNet synsets assigned to the lexical entries shared by the two resources is detailed, as well as a number of queries that can be run across the interoperable resources for Latin currently included in LiLa.

Published: September 2021

Knowledge graphs facilitate systematic large-scale data analysis by providing both human and machine-readable structures, which can be shared across different domains and platforms. Nowadays, knowledge graphs can be used to standardise the collection and sharing of user information in many different sectors such as transport, insurance, smart cities and internet of things. Regulations such as the GDPR make sure that users are not taken advantage of when they share data. From a legal standpoint it is necessary to have the user’s consent to collect information. This consent is only valid if the user is aware about the information collected at all times. To increase this awareness, we present a knowledge graph visualisation approach, which informs users about the activities linked to their data sharing agreements, especially after they have already given their consent. To visualise the graph, we introduce a user-centred application which showcases sensor data collection and distribution to different data processors. Finally, we present the results of a user study conducted to find out whether this visualisation leads to more legal awareness and trust. We show that with our visualisation tool data sharing consent rates increase from 48% to 81.5%.

Published: September 2021

Infusing autonomous artificial systems with knowledge about the physical world they inhabit is of utmost importance and a long-lasting goal in Artificial Intelligence (AI) research. Training systems with relevant data is a common approach; yet, it is not always feasible to find the data needed, especially since a big portion of this knowledge is commonsense. In this paper, we propose a novel method for extracting and evaluating relations between objects and actions from knowledge graphs, such as ConceptNet and WordNet. We present a complete methodology of locating, enriching, evaluating, cleaning and exposing knowledge from such resources, taking into consideration semantic similarity methods. One important aspect of our method is the flexibility in deciding how to deal with the noise that exists in the data. We compare our method with typical approaches found in the relevant literature, such as methods that exploit the topology or the semantic information in a knowledge graph, and embeddings. We test the performance of these methods on the Something-Something Dataset.

Aim: to evaluate additive IOP-lowering effect of brimonidine 0.2% to achieve target IOP via enhancing maximum tolerated medical therapy for primary open-angle glaucoma (POAG). Patients and Methods: 63 patients (63 eyes) with advanced POAG and poorly controlled IOP who received prostaglandin analogs and a fixeddose carbonic anhydrase inhibitor/beta-blocker combination were enrolled. All patients were additionally prescribed with brimonidine 0.2%. After a month, patients were divided into two groups based on achieved IOP level. In group 1, target IOP was achieved, and these patients were followed up. In group 2, target IOP was not achieved, and these patients underwent trabeculectomy. IOP was measured by elastotonometry and using the iCare tonometer. Results: a month after prescribing α2 agonist, true IOP level reduced to 14.0 (9.5; 17.0) mm Hg in group 1 and to 17.0 (13.0; 20.0) mm Hg in group 2. At the final visit, IOP levels were within target ranges in both groups, i.e., 13.0 (11.0; 18.5) mm Hg and 13.5 (9.7; 17.2) mm Hg, respectively. Meanwhile, changes in IOP measured by various methods were significantly different. IOP reduced by 5.4% (-7.1%; 17.6%) in group 1 and by 20.7% (4.4%; 30.7%) in group 2 (p<0.05) as measured by elastotonometry and by 8.3% (-11.8%; 28.6%) in group 1 and by 33.3% (13.9%; 50.7%) in group 2 as measured by iCare tonometer. Conclusions: brimonidine 0.2% provides additional IOP reduction to enhance maximum tolerated medical therapy for advanced POAG. An estimated effect of brimonidine is a 8% reduction of IOP from the baseline. If target IOP is not achieved, a patient should be scheduled for surgery. IOP should be measured using the iCare tonometer since this device is more sensitive to minor IOP fluctuations.

Albinism is a clinically and genetically heterogeneous group of hereditary diseases whose pathogenesis is mediated by impaired synthesis of melanin which results in its partial or total loss. Reduced melatonin level clinically manifests as skin, hair, and ocular hypopigmentation. Ocular presentations include hypopigmentation/lack of pigmentation of eye fundus and iris, foveal hypoplasia, low vision, nystagmus and strabismus, photophobia, iris transillumination, and asymmetrical decussation of nerve fibers at the optic chiasm. However, albinism can be a part of more complex genetic syndromes, e.g., Hermansky-Pudlak syndrome or Chediak-Higashi syndrome. These disorders should be identified as early as possible to start therapy to prevent life-threatening conditions. Partial albinism with ocular, skin or hair hypopigmentation not associated with melanogenesis (e.g., Griscelli syndrome, Waardenburg syndrome, Aland Island eye disease, etc.) also occurs. Each case of albinism requires an accurate molecular genetic diagnosis to provide a personalized treatment approach, predict life expectancy and health status, and plan pregnancy. Keywords: albinism, Hermansky-Pudlak syndrome, Chediak-Higashi syndrome, hypopigmentation, clinical polymorphism, genetic heterogeneity.

Cross-linking new technologies application in the treatment of severe corneal pathologies of various etiologies in dogs and cats
Authors: Lukashina Ul'yana , Artyushina Yuliya
Published: September 2021

The article presents the results of the clinical application of new technology — UV-corneal collagen cross-linking procedure, which we use in the complex therapy of severe corneal pathologies for dogs and cats: septic ulcers complicated by keratomalacia, keratectasias of various origins, endothelial-epithelial corneal dystrophies. The UV cross-linking method is often performed by us as a stage in the preparation of a donor graft during keratoplasty operations in dogs and cats. The effect of the cross-linking treatment procedure is achieved by photopolymerizing collagen fibers of corneal stroma under the combined action of photosensitizer (riboflavin solution) and ultraviolet radiation with a certain wavelength. After cross-linking, it is possible to achieve increase in the biomechanical and biochemical stability of the cornea, to observe dehydration and antimicrobial effects. The article contains information about the stages and results of several methods of UV-corneal collagen cross-linking, which we successfully use in clinical practice in dogs and cats: A-CXL method, PACK-CXL, M-CXL, method of cross-linking modification of donor heterologous graft as a stage in performing keratoplasty surgery to recipient. Based on our clinical results, we can conclude that corneal cross-linking in dogs and cats has a high therapeutic potential and is a promising method for treating severe keratopathies in cases of weak effectiveness of traditional drug therapy regimens.

In this paper disturbance observer-based control (DOBC) system for PMSM has been proposed. The cascade structure of the discrete-time PI-PI control system with back-calculation anti-windup scheme for both loops has been adopted. High order disturbance observer (HODO) has been adopted to estimate the total disturbance and compensate it in the speed loop of the PMSM control system. In the HODO, the disturbance estimation is based on the motion equation which takes into account torque losses due to the drug resulting from the time-varying flux, hysteresis, and friction. Unlike the traditional observers, the HODO does not require the derivatives of the disturbance to be zero, which is considered as its main advantage. The fast-varying disturbance as cogging torque and a high-frequency electromagnetic noise in the PMSM system also affect on the performance of control system, which are analyzed in the study. In the real-time experiments, the proposed control system achieves less speed errors and faster response comparing with controller without disturbances observer. The experimental results have proved the feasibility of the proposed control scheme.

Background and Aim: Gynecological cancer is one of the most common types of cancer worldwide. Nonetheless, spinal metastasis from gynecological cancer is scarcely reported in the literature. In cases of spinal cord compression, the standard treatment is a decompressive surgery followed by radiotherapy treatment for selected patients. This study aimed to report the overall survival and surgical results in patients presenting with gynecological spinal metastases who underwent spinal cord/nerve root decompression and stabilization. Methods and Materials/Patients: A total of 18 patients were included in this study. The surgical procedures were performed from 2012 to 2019. The evaluation of neurological status, spinal stability, and pain were performed using the American Spinal Injury Association Impairment Scale (ASIA), Spinal Instability Neoplastic Score (SINS), and Visual Analogue Scale (VAS), respectively. Results: The lumbar spine was the most affected location (n=30; 50.0%). Regarding the preoperative neurological deficits, 16 cases (n=16; 88.9%) presented ASIA graded A–D before the surgery, being reduced to five (n=5; 27.8%) after the procedures. The pain level means (pre-and postoperative) were 9.39±0.79 and 2.28±1.44. The overall median survival was 6.1 months (95% Confidence Interval [CI] of 1.10–11.13 months). The mean survival of ambulatory and non-ambulatory patients before the surgery was 7.36 months and 3.2 months, respectively (P=0.007 – Log-rank Mantel–Cox). Conclusion: Decompressive surgery and stabilization promote mechanical pain relief, spinal stability, an improvement of neurological function, and indirectly improving quality of life, despite a dismal overall survival of patients who present with metastatic spinal compression disease.

Background and Importance: SARS-CoV-2 virus causes COVID-19. The virus’s primary target is the respiratory system, but it can also affect other systems, such as the cardiovascular and the central nervous system. Case Presentation: In this study, we introduce an 83-year-old man who was referred due to a reduced level of consciousness and hemiparesis in the left part of his body without symptoms such as fever, cough, muscle aches, and fatigue. In High-Resolution Computed Tomography (HRCT) of the lung, the Ground-Glass Opacification/Opacity (GGO) view indicated COVID-19 disease, and in Computerized Tomography (CT) scans of the brain, hemorrhage was evident in the right thalamus, lateral and right ventricle. The Polymerase Chain Reaction (PCR) test performed on the upper part of the nose was also positive. This research is a case report of intracranial and intraventricular hemorrhage in an aged man with asymptomatic COVID-19. Conclusion: Low level of consciousness in the elderly can be a sign of infection with the SARS-CoV-2 virus.

Background: Patients need peace of mind to disclose their information to medical staff and with the lack of trust or in specific health status, they may avoid providing sensitive information for their care or might change the information. This research was done to examine the impact of perceived health status and trust propensity on privacy calculus. Methods: In this analytical research three questionnaires, namely Trust Propensity, Health Status (Goldberg and Hiller), and Privacy Calculus were used. The statistical population consisted of the patients of one of the Ahvaz hospitals. Following sample size determination using the Morgan table, 379 usable questionnaires were collected non-randomly. The majority of respondents were younger than 30 and male. After face, content, and construct validities, the reliability was examined through Cronbach’s alpha and composite reliability and the hypotheses were examined by partial least square method, using SmartPLS. Results: Patients’ privacy calculus was associated with trust propensity and perceived health status (P<0.05), while trust propensity had no correlation with perceived advantages and disadvantages of privacy disclosure. The relationship between perceived health status and advantages and disadvantages of information disclosure was positively significant (P<0.05). Conclusion: In order to improve patients’ provision of rich information to medical staff, their trust propensity should be improved.
