Authors: Mazur O. A. , Salo S. V.
Published: October 2019

Ехокардіографія (ЕхоКГ) є універсальним і економічно ефективним методом візуалізації для оцінювання стану пацієнтів з нестабільними серцево-судинними захворю-ваннями. У високорозвинутих країнах потребу в невідкладній ЕхоКГ задовольняють лікарі за протоколом FoCUS (Focused Cardiac Ultrasound – прицільна ЕхоКГ).

У цьому дослідженні проаналізовано роботу відділення ультразвукової діагностики Націо-нального інституту серцево-судинної хірургії та можливості впровадження протоколів FoCUS для екстреної ЕхоКГ пацієнтам інституту. У роботі використовувались дані руху стаціонарних хворих та журналу проведення ЕхоКГ по швидкій допомозі за 2018 рік. За отриманими да-ними, необхідність проведення ЕхоКГ експертного рівня в позаробочий час мала місце значно рідше порівняно з потребою у FoCUS. Отже, навчання лікарів, які надають невідклад-ну допомогу, за програмою FoCUS та широке впровадження портативних ЕхоКГ-пристроїв дозволить прискорити прийняття рішення в екстрених випадках.

Published: October 2019

NHP are a small, but critical, portion of the animals studied in research laboratories. Many NHP are imported or raised at one facility and subsequently moved to another facility for research purposes. To improve our understanding of the effects of transportation and relocation on the
NHP immune system, to minimize potential confounds associated with relocation, and to maximize study validity, we examined the phenotype and function of PBMC in cynomolgus macaques (Macaca fascicularis) that were transported approximately 200 miles by road from one facility to another.
We evaluated the phenotype of lymphocyte subsets through flow cytometry, mitogen-specific immune responses of PBMC in vitro, and plasma levels of circulating cytokines before transportation, at approximately 24 h after arrival (day 2), and after 30 d of acclimation. Analyses of blood samples
revealed that the CD3+ and CD4+ T-cell counts increased significantly, whereas NK+, NKT, and CD14+ CD16+ nonclassical monocyte subsets were decreased significantly on day 2 after relocation compared with baseline. We also noted significantly
increased immune cell function as indicated by mitogen-specific proliferative responses and by IFNγ levels on day 2 compared with baseline. After 30 d of acclimation, peripheral blood CD4+ T-cells and monocyte counts were higher than baseline, whereas B-cell numbers were lower.
The mitogen-induced responses to LPS and IFNγ production after stimulation with pokeweed mitogen or phytohemagglutinin remained significantly different from baseline. In conclusion, the effects of transportation and relocation on immune parameters in cynomolgus monkeys are significant
and do not fully return to baseline values even after 30 d of acclimation.
Phylogenetic placement of Paratrichaptum and reconsideration of Gloeophyllales
Authors: Chen C.-C. , Cao B. , Hattori T. , Cui B.-K. , Chen C.-Y. , Wu S.-H.
Published: October 2019

Paratrichaptum accuratum is a large conspicuous polypore fungus growing on dead or living angiosperm trees in subtropical-boreal areas of China, Indonesia, Japan, and Taiwan. The present study places P. accuratum in the family Gloeophyllaceae that belongs to the
order Gloeophyllales within Agaricomycetes (Basidiomycota), based on evidence derived from morphological and ecological characteristics, and phylogenetic analyses of sequences of nuclear rDNA regions (5.8S, nuc 18S, nuc 28S) and protein-coding genes (rpb1,
rpb2, and tef1). The analyses presented in this study also give strong support for including Jaapia in Gloeophyllaceae and Gloeophyllales. Thus, the names Jaapiaceae and Jaapiales are considered here as synonyms of Gloeophyllaceae and
Gloeophyllales. Since Paratrichaptum represents the earliest diverging lineage in Gloeophyllales, pileate basidiocarps and brown rot appear to be ancestral states of Gloeophyllales. Paratrichaptum accuratum may represent a relic species, according to its phylogenetic
position, peculiar distribution pattern and rare occurrence.
Writing Rasch Analysis at a Glance
Authors: Setiawan Adib Rifqi
Published: October 2019

One of tenets in education is learning assessment. Assessment is fundamentally the act of using questions to reveal the extent to which teachers are changing students’ academic performance through learning. Unfortunately, assessment is a necessary task but complicated. Without a carefully developed measurement instrument that captures the indicators of learning, it is very difficult if not impossible to make meaningful assessment. This essay provides an explanation of Rasch Analysis at a glance, as a technique to develop assessment instrument based on the indicators of learning which want to assess. One of the most powerful aspects of Rasch Analysis is this technique allows the meaning of student measures and the meaning of group measures to be explained using the context of the instrument’s items. For a test, if a group of students improves from pre to post, a teacher can explain the meaning of the change.
A conceptual framework for understanding the cultural and contextual factors on autism across the globe
Authors: de Leeuw Annde , Happé Francesca , Hoekstra Rosa
Published: October 2019

Autism research is heavily skewed towards western high-income countries. Culturally appropriate screening and diagnostic instruments for autism are lacking in most low- and middle-income settings where the majority of the global autism population lives. To date, a clear overview of the possible cultural and contextual factors that may affect the process of identifying and diagnosing individuals with ASD is missing. This study aims to outline these factors by proposing a conceptual framework. A multidisciplinary review approach was applied to inform the development of the conceptual framework, combining a systematic review of the relevant autism research literature with a wider literature search spanning key texts in global mental health, cultural psychiatry, cross-cultural psychology and intellectual disability research. The resulting conceptual framework considers the identification, help-seeking and diagnostic process at four interrelated levels: i) the expression, ii) recognition, iii) interpretation and iv) reporting of autism symptoms, and describes the cultural and contextual factors associated with each of these levels, including cultural norms of typical and atypical behaviour, culture-specific approaches to parenting, mental health literacy, cultural beliefs, attitudes and stigma, as well as the affordability, availability, accessibility and acceptability of services. This framework, mapping out the cultural and contextual factors that can affect the identification, help-seeking and diagnosis of ASD, may function as a springboard for the development of culturally appropriate autism screening and diagnostic instruments, and inform future cross-cultural autism research directions. The framework also has relevance for clinicians and policy makers aiming to improve support for underserved autism populations worldwide.
Causal Effects Based on Latent Variable Models
Authors: Mayer Axel
Published: October 2019

Building on the stochastic theory of causal effects and latent state-trait theory, this article shows how a comprehensive analysis of the effectiveness of interventions can be conducted based on latent variable models. The proposed approach offers new ways to evaluate the differential effectiveness of interventions for substantive researchers in experimental and observational studies while allowing for complex measurement models. The key definitions and assumptions of the stochastic theory of causal effects are first introduced and then four statistical models that can be used to estimate various types of causal effects with latent state-trait models are developed and illustrated: The multistate effect model with and without method factors, the true-change effect model, and the multitrait effect model. All effect models with latent variables are implemented based on multigroup structural equation modeling with the EffectLiteR approach. Particular emphasis is placed on the development of models with interactions that allow for interindividual differences in treatment effects based on latent variables. Open source software code is provided for all models.

Authors: Bijani Mostafa , Khaleghi Ali Asghar
Published: October 2019

Background: Correct and fast triage is the key to successful performance in emergency departments. Various factors can affect the quality of triage; therefore, the present study was conducted to identify and explore the existing challenges in triage units in emergency departments. Materials and Methods: The present study was a qualitative exploratory work conducted via the content analysis approach. Data were collected using in-depth, semi-structured interviews, and focus group interviews. Accordingly, 22 in-depth, semi-structured interviews were conducted in with 18 triage nurses and four emergency medicine specialists on a face-to-face basis. Results: The challenges related to triage nurses fall into two subcategories; lack of clinical competency and psychological capabilities. The challenges related to emergency management consist of challenges in human resources management, structural, and performance. Conclusion: The challenges existing in triage units are influenced by factors related to triage nurses and emergency management. Emergency administrators can improve the effectiveness and quality of triaging patients by empowering triage nurses and removing structural problems in triage units.[GMJ.2019;8:e1619]
Anterior capsulotomy for obsessive-compulsive disorder: a review of old and new literature
Authors: Pepper Joshua , Zrinzo Ludvic , Hariz Marwan
Published: October 2019

Over the last two decades, deep brain stimulation (DBS) has gained popularity as a treatment of severe and medically refractory obsessive-compulsive disorder (OCD), often using brain targets informed by historical lesional neurosurgical procedures. Paradoxically, the use of DBS in OCD has led some multidisciplinary teams to revisit the use of lesional procedures, especially anterior capsulotomy (AC), although significant aversion still exists toward the use of lesional neurosurgery for psychiatric disorders. This paper aims to review all literature on the use of AC for OCD to examine its effectiveness and safety profile.

All publications on AC for OCD were searched. In total 512 patients were identified in 25 publications spanning 1961–2018. In papers where a Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score was available, 73% of patients had a clinical response (i.e., > 35% improvement in Y-BOCS score) and 24% patients went into remission (Y-BOCS score < 8). In the older publications, published when the Y-BOCS was not yet available, 90% of patients were deemed to have had a significant clinical response and 39% of patients were considered symptom free. The rate of serious complications was low.

In summary, AC is a safe, well-tolerated, and efficacious therapy. Its underuse is likely a result of historical prejudice rather than lack of clinical effectiveness.
Association of cause of injury and traumatic axonal injury: a clinical MRI study of moderate and severe traumatic brain injury
Authors: Moe Hans Kristian , Limandvik Myhr Janne , Moen Kent Gøran , Håberg Asta Kristine , Skandsen Toril , Vik Anne
Published: October 2019

OBJECTIVE

The authors investigated the association between the cause of injury and the occurrence and grade of traumatic axonal injury (TAI) on clinical MRI in patients with moderate or severe traumatic brain injury (TBI).

METHODS

Data for a total of 396 consecutive patients, aged 7–70 years, with moderate or severe TBI admitted to a level 1 trauma center were prospectively registered. Data were included for analysis from the 219 patients who had MRI performed within 35 days (median 8, IQR 4–17 days) and for whom cause of injury was known. Cause of injury was registered as road traffic accident (RTA) or fall (both with respective subcategories), alpine skiing or snowboarding accident, or violence. The MRI protocol consisted of T2*-weighted gradient echo, FLAIR, and diffusion-weighted imaging scans. TAI lesions were evaluated in a blinded manner and categorized into 3 grades, hemispheric/cerebellar white matter (grade 1), corpus callosum (grade 2), and brainstem (grade 3). The absence of TAI was analyzed as grade 0. Contusions and mass lesions on CT were also registered.

RESULTS

Cause of injury did not differ between included and nonincluded patients. TAI was found in 83% of patients in the included group after RTAs and 62% after falls (p < 0.001). Observed TAI grades differed between the subcategories of both RTAs (p = 0.004) and falls (p = 0.006). Pedestrians in RTAs, car drivers/passengers in RTAs, and alpine skiers had the highest prevalence of TAI (89%–100%) and the highest TAI grades (70%–82% TAI grades 2–3). TAI was found in 76% of patients after falls from > own height (45% TAI grade 2–3), 63% after falls down the stairs (26% TAI grade 2–3), and 31% after falls from ≤ own height (12% TAI grade 2–3). Moreover, 53% of patients with TAI after RTAs and 68% with TAI after falls had cortical contusions or mass lesions on CT.

CONCLUSIONS

This prospective study of moderate and severe TBI is to the authors’ knowledge the first clinical MRI study to demonstrate both the high prevalence and grade of TAI after most of the different types of RTAs, alpine skiing accidents, and falls from a height. Importantly, TAI was also common following more low-energy trauma such as falls down the stairs or from own height. Physicians managing TBI patients in the acute phase should be aware of the possibility of TAI no matter the cause of injury and also when the CT scan shows cortical contusions or mass lesions.

Published: October 2019

OBJECTIVE

The purpose of this study was to investigate the morphology, connectivity, and correlative anatomy of the longitudinal group of fibers residing in the frontal area, which resemble the anterior extension of the superior longitudinal fasciculus (SLF) and were previously described as the frontal longitudinal system (FLS).

METHODS

Fifteen normal adult formalin-fixed cerebral hemispheres collected from cadavers were studied using the Klingler microdissection technique. Lateral to medial dissections were performed in a stepwise fashion starting from the frontal area and extending to the temporoparietal regions.

RESULTS

The FLS was consistently identified as a fiber pathway residing just under the superficial U-fibers of the middle frontal gyrus or middle frontal sulcus (when present) and extending as far as the frontal pole. The authors were able to record two different configurations: one consisting of two distinct, parallel, longitudinal fiber chains (13% of cases), and the other consisting of a single stem of fibers (87% of cases). The fiber chains’ cortical terminations in the frontal and prefrontal area were also traced. More specifically, the FLS was always recorded to terminate in Brodmann areas 6, 46, 45, and 10 (premotor cortex, dorsolateral prefrontal cortex, pars triangularis, and frontal pole, respectively), whereas terminations in Brodmann areas 4 (primary motor cortex), 47 (pars orbitalis), and 9 were also encountered in some specimens. In relation to the SLF system, the FLS represented its anterior continuation in the majority of the hemispheres, whereas in a few cases it was recorded as a completely distinct tract. Interestingly, the FLS comprised shorter fibers that were recorded to interconnect exclusively frontal areas, thus exhibiting different fiber architecture when compared to the long fibers forming the SLF.

CONCLUSIONS

The current study provides consistent, focused, and robust evidence on the morphology, architecture, and correlative anatomy of the FLS. This fiber system participates in the axonal connectivity of the prefrontal-premotor cortices and allegedly subserves cognitive-motor functions. Based in the SLF hypersegmentation concept that has been advocated by previous authors, the FLS should be approached as a distinct frontal segment within the superior longitudinal system.

Published: October 2019

OBJECTIVE

The goal of this study was to demonstrate the use of quantitative susceptibility mapping (QSM)–based images to precisely localize the globus pallidus internus (GPi) for deep brain stimulation (DBS) planning and to enhance postsurgical visualization of the DBS lead positions.

METHODS

Presurgical T1-weighted (T1w), T2-weighted (T2w), and QSM images as well as postsurgical CT images were obtained in 29 patients with Parkinson’s disease. To enhance the contrast within the GP, a hybrid contrast was created by linearly combining T1w and QSM images. Contrast-to-noise ratios (CNRs) of the GPi on T1w, T2w, QSM, and hybrid images were compared. The CNR differences were tested using the 1-way ANOVA method. The visualization of the DBS lead position was demonstrated by merging the postsurgical CT with presurgical MR images.

RESULTS

The hybrid images yield the best CNRs for GPi depiction and the visualization of the postsurgical DBS lead position was significantly improved.

CONCLUSIONS

QSM-based images allow for confident localization of borders of the GPi that is superior to T1w and T2w images. High-contrast hybrid images can be used for precisely directed DBS targeting, e.g., GPi DBS for the treatment of advanced Parkinson’s disease.

Kurikulum dipandang sebagai suatu program yang didisain, direncanakan, dikembangkan, dan akan dilaksanakan dalam situasi belajar mengajar yang sengaja diciptakan di sekolah. Berdasarkan pengamatan yang penulis lakukan, penulis mendapati bahwa proses belajar mengajar di SMA Tunas Baru Ciparay belum berjalan dengan baik diakibatkan oleh administrasi kurikulum yang belum berjalan sebagaimana mestinya. sebagai berikut: (1) Penyusunan jadwal yang sering diubah yang disebabkan karena banyak guru yang mengajar di tempat lain. Pihak sekolah harus menyesuaikan jadwal para guru terutama mereka yang mengajar di sekolah lain.; (2) tingkat absensi guru dan siswa cukup tinggi ; (3) guru jarang membuat perangkat pembelajaran karena kepala sekolah jarang memeriksanya;(4) Penempatan guru yang tidak tepat, banyak guru yang mengajar di luar bidang kemampuannya. Dari keempat permasalahan diatas dapat disimpulkan bahwa inti permasalahan pada SMA Swasta Tunas Baru Ciparay terletak pada kelemahan kepala sekolah dalam melaksanakan fungsinya. Rekomendasi kepada Kepala Sekolah sebagi pelaksana kurikulum disekolah sebaiknya mengambil tindakan: (1) Memberikan teladan yang baik bagi guru dan staf dalam hal kedisiplinan;(2) memberikan sanksi bagi guru yang kurang disiplin.; (3) memberikan apresiasi/reward bagi guru yang disiplin; (4) memberikan pembinaan bagi para guru baik secara formal maupun informal; dan (5) menempatkan guru dan staf sesuai dengan kemampuannya (the right man in the right place).

Published: October 2019

Dengue Hemorrhagic Fever (DHF) is an endemic disease caused by a virus and transmitted by vectors, especially Aedes aegypti and Ae. Albopictus. The number of cases tends to increase and is widespread in almost all regions. This study aims to determine the different types of water sources on the attractiveness of Aedes aegypti for laying eggs. The research method uses the One Way Anova statistical test analysis with α <0.05. The results showed the One Way Anova test obtained p value = 0.048 (p <0.05) meaning that there are differences in the type of water source to the attractiveness of Aedes aegypti mosquitoes to lay eggs, especially in well water with river water with a value of p = 0.016 (p <0, 05). The difference in the number of mosquito eggs found in containers containing rain water, river water and well water indicates that the Aedes aegypti mosquito has different appeal in laying its eggs. The community should always maintain sanitation, especially containers that hold water so that it does not have the potential to become Aedes aegypti mosquito nest sites and can reduce the density of Aedes aegypti mosquitoes.
Harga Jual BioCNG dari Palm Oil Mill Effluent sebagai Sumber Energi Alternatif
Authors: Febijanto Irhan
Published: October 2019

Indonesia as the largest producer of palm oil, produces huge palm oil wastewater. The wastewater produces biogas which contributes to global warming, and the utilization of the biogas reduces GHG emissions of methane gas. By increasing the concentration of methane gas in the biogas, and increasing the gas pressure of biomethane, so-called bioCNG (Compressed Natural Gas), the gas utilization easier in the transportation and the energy content of the gas increases. In this paper, an assessment of the economics of bioCNG production facility in the Palm Oil Mill (POM) with a capacity of 60 tons/hour was conducted. The investment cost is estimated based on the biogas flow rate produced from an aerobic digester in the POM. By using a covered lagoon technology for anaerobic digester, and technology of membrane for gas purification, and based on the natural gas trading regulations, the selling price of bioCNG is determined by 10.27 USD/MMBTU with an IRR of 12%. This price can compete with the prices of other fossil fuels. However, the support from government regulations are still needed to utilize bioCNG as a new renewable fuel that can contribute to national energy security, GHG reduction, and achievement of the mix energy target.

Wind power is dominant energy converted into electricity through wind turbine generators used in wind energy conversion systems. Technological developments produce various types of generators for use in wind power plants of various scales. Permanent magnet generator (PMG) has advantage of being able to produce electrical energy of 500 watts at rotation 600 rotate per minute with an input wind speed of 2.5-12 m/s. The potential for average wind speed throughout the year in Aceh is around 1.5-6.5 m/s cannot be generate electric power because mechanical energy from turbine rotation is not sufficient to meet the minimum demand for RPM generators. The design of a horizontal axis wind turbine (HAWT) with Air Foil Naca 2410 is used to increase the efficiency of the turbine rotation. It’s influenced by variations in the number of blades and material used. Stages of simulation are prioritized to get efficient variations of the number of blades and the most effective material testing is performed. The results showed that variation of the axis of a three-blade wind turbine type has a higher coefficient of power that is 50 percent compared the other, the type of material wind turbines made from pinus more optimal than fiberglass.

Nitrogen fertilizer represents major economic burden. For this reason, although the efficiency of nitrogen utilization varies highly, its actual use generally remains at low levels; these averaging between 25 and 50%. We set up an experiment at the Oradea Research Station, using 15N labeled fertilizers, in order to investigate the possibility of increasing N fertilizer efficiency in winter wheat under irrigation conditions.Fertilizers labeled with 15N allows us to individually determine its effect on yield formation, as well as the use efficiency of N from fertilizer following application rate and time. The amount of N derived from fertilizer as determined in straw and grain yield is high. When the labeled fertilizer is applied at tillering time, the values of this indicator rise when higher N levels we applied.In separate experiments, we investigated a series of aspects connected to chemical fertilizer regarding the determination of the type of fertilizer, optimum time and rates of application; all these as a function of the special pedoclimatic conditions.The results obtained in the field show that the effectiveness of N utilization in wheat is most variable and generally low, often ranging between 25 and 33%, owing to N loss within the system through leaching and NH3 volatilization.A readily achievable increase in efficiency of 5 percentage points would result in considerable savings, and can be brought about by reducing nitrogen losses. The added benefits to the environment in terms of reduced ground/water contamination and lowered nitrous oxide (N20) emissions would also be substantial.The figures for N fertilizer use efficiency (% N range from 35.5 to 72.6, the highest value being recorded with an N application of 120 kg/ha at tillering, when the previous crop was sunflower).INTRODUCTION
Effects of production factors on the yield and yield component of winter wheat
Authors: Lesznyák Mátyásné
Published: October 2019

The effect of major production factors (forecrop, fertilisation, irrigation, soil cultivation and soil preparation) on the yield components and yield of winter wheat were studied in a long-term  experiment set up at the Látókép Experimental Nursery of the Agricultural Sciences Centre of the University of Debrecen. The results of regression analysis led to the following conclusions:• In our experiments in 2000, after using maize as a forecrop –based on the results of analysis of regression – fertilisation determined the yield.• After using pea as a forecrop, a N50 P35 K40 kg/ha fertiliser rate led to an economical increase in the yield of winter wheat.• None of the determinative yield components varied significantly for winter wheat produced after using pea as a forecrop.• There is a closed, significant correlation between plant height, spike length, plant and spike mass, the number of spikelets and grains per spike after using maize as forecrop. The thousand grain mass is different from the other yield components, because it is not part of the relation system ofthose yield components.• The increased yield of winter wheat after maize has been used as a forecrop is due to the positive change in grain number per spike yield component.
Impact of fertilization on production capacity and reaction to fertilization in maize hybrids
Authors: Jakab Péter
Published: October 2019

New varieties and fertilization have significantly increased yields of maize in recent decades. It has to be taken into account however that the interactions and the balanced combination of cropping factors (ecological, biological and agrotechnical) are the main factors which determine yields. Weather conditions were rather unfavourable during the last decade. Extreme weather conditions occurred due to global warming; 6 of 10 years were plagued by drought. Consequently yields increased from 10-20% to 30-50%. In view of varieties the situation is advantageous, maybe the supply of hybrids is too high, nevertheless those hybrids need to be selected which are particularly well adjusted to the ecological conditions. Many technologies can be applied which vary according to intensity, but the balanced combination of cropping factors should be secured on the basis of the hybrid’s intensity. Among agrotechnical factors the compensation of nutrients and technological conditions were inadequate. These days farmers only use nitrogenous fertilizers consequently they significantly decrease the easily available P and K content of the soil which in long term leads to the deterioration of the soil’s productivity. The technological background is therefore important, because sufficient yields can only be expected if agrotechnical operations are carried out in the right time and quality.

intra-continental migration has increased within Africa since the late 1980s. Africa to Africa migration ranks fifth globally. This study intended to review studies and document risk factors for depression, depressive symptoms, screening programs and coping strategies among voluntary African migrants within Africa. Online databases search was done to select journal articles published between 1980 and 2018 about the topic. PubMed generated only 8 relevant studies, Google Scholar 11, African Journals Online only 1 and international websites 3 relevant ones. Based on the keywords, Cochran protocol for quality assessment and PRISMA flowchart, 16 articles were systematically reviewed. Findings indicate few studies on depression among voluntary African migrants in Africa. Migration itself is a risk factor for depression. Other factors are trauma, poverty, forced or illegal migration, acculturation, loneliness, age, family separation, changing gender roles, and first-time migrants. It presents as insomnia, anxiety and social dysfunction. Most screening programs available are client-initiated. Family support systems, problem-focused or emotions focused coping strategies can lessen depression. Conclusively, depression is a common scenario among migrants whether voluntary or involuntary but screening programs targeting voluntary migrants are very rare in most African settings. Culturally relevant and appropriate approaches targeting voluntary migrants would address the issue.
Automated Fixture Design using an Imprint-based Design Approach and Optimisation in Simulation
Authors: Schwartz Lukas
Published: October 2019

Object aligning and holding fixtures for robotic assembly tasks are important in industry in order to successfully complete an assembly. However, the designing of a fixture is usually done manually which can be a long and tedious process including many iterations, even for experienced engineers. This paper presents a method to design fixtures automatically for use in robotic assemblies and pick-and-place tasks. To achieve this, a new automated method to design the cut-out for a fixture is introduced. The method uses a parameterized version of the object's imprint to design the cut-out. The fixtures generated using this method are optimized in simulations to determine their final parameters for a specific application. Dynamic simulations are used to evaluate each iteration of the cut-out. Lastly, the method is applied to a use-case from the industry to design a fixture for use in a robotic assembly task.
