Authors: Muzakir Ari , Ependi Usman
Published: March 2022

Purpose: Many studies have conducted studies related to automation for image-based plant species identification recently. Types of plants, in general, can be identified by looking at the shape of the leaves, colors, stems, flowers, and others. Not everyone can immediately recognize the types of plants scattered around the environment. In Indonesia, herbal plants thrive and are abundantly found and used as a concoction of traditional medicine known for its medicinal properties from generation to generation. In the current Z-generation era, children lack an understanding of the types of plants that benefit life. This study identifies and predicts the pattern of the leaf shape of herbal plants. Methods: The dataset used in this study used 15 types of herbal plants with 30 leaf data for each plant to obtain 450 data used. The extraction process uses the GLCM algorithm, and classification uses the K-NN algorithm. Result: The results carried out through the testing process in this study showed that the accuracy rate of the leaf pattern prediction process was 74% of the total 15 types of plants used. Value: Process of identifying and predicting leaf patterns of herbal plants can be applied using the K-NN classification algorithm combined with GLCM with the level of accuracy obtained.

Purpose: Heart failure is a disease that is still a global threat and plays a major role as the number one cause of death worldwide. Therefore, accurate predictions are needed to determine the survival of heart failure patients. One technique that can be used to predict a decision is classification. Adaptive Neuro-Fuzzy Inference System (ANFIS) is an algorithm that can be used in the classification process in making predictions. Genetic Algorithms can help improve the performance of classification algorithms through the feature selection process. Methods/Study design/approach: In this study, predictions or diagnoses were made on the survival of heart failure patients based on the heart failure clinical record dataset obtained from the UCI Machine Learning Repository. The data used is 299 data with 12 attributes and 1 class. The result of this research is the comparison of the accuracy of the ANFIS algorithm before and after using the Genetic Algorithm. Result/Findings: The ANFIS algorithm produces the highest accuracy of 94.444%. While the ANFIS algorithm after attribute selection using the Genetic Algorithm produces the highest accuracy of 96.667%. This shows that the Genetic Algorithm is able to improve the performance of the ANFIS classification algorithm through the attribute selection process.

Understanding shoulder pseudoparalysis: Part I: Definition to diagnosis
Authors: Bauer Stefan , Okamoto Taro , Babic Stephanie M , Coward Jonathon C , Coron Charline M P L , Blakeney William G
Published: March 2022

Variable definitions of pseudoparalysis have been used in the literature.

Recent systematic reviews and biomechanical studies call for a grading of loss of force couple balance and the use of the terms ‘pseudoparesis’ and ‘pseudoparalysis’.

Pain should be excluded as the cause of loss of active function.

Key players for loss of force couple balance seem to be the lower subscapularis as an anterior inferior checkrein and the teres minor as a posterior inferior fulcrum.

Loss of three out of five muscle–tendon units counting upper and lower subscapularis separately is predictive of pseudoparalysis.

Shoulder equator concept: loss of all three posterior, or all three superior, or all three anterior muscle–tendon units is predictive of pseudoparalysis (loss of fulcrum for deltoid force).

Every effort should be made to prevent propagation of rotator cuff tears into the subscapularis and posterior rotator cuff (infraspinatus and teres minor) to maintain force couple balance (value of partial cuff repair).

Clinical assessment of active forward elevation, active external rotation, and active internal rotation is important to define and grade the severity of loss of force couple balance.

Additional features such as patient age, traumatic aetiology, chronicity, fatty infiltration, and stage of cuff tear arthropathy are useful for a specific diagnosis with implications for treatment.

Published: March 2022

Prosthetic hip-associated cobalt toxicity (PHACT) is caused by elevated blood cobalt concentrations after hip arthroplasty.

The aim of this study is to determine which symptoms are reported most frequently and in what type of bearing. We also try to determine the blood level of cobalt concentrations associated with toxicological symptoms.

A systematic review was conducted on the 10th of July according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A methodological quality assessment (risk of bias (RoB)) was performed. Primary outcomes were the reported symptoms of cobalt toxicity and the level of cobalt concentrations in blood. These levels were associated with toxicological symptoms. A total of 7645 references were found of which 67 relevant reports describing 79 patients.

The two most used bearings in which PHACT was described were metal-on-metal (MoM) bearings (38 cases) and revised (fractured) ceramic-on-ceramic (CoC) bearings where the former ceramic head was replaced by a metal head (32 cases).

Of all reported symptoms, most were seen in the neurological system, of which 24% were in the sensory system and 19.3% were in central/peripheral system, followed by the cardiovascular (22.1%) system.

The mean cobalt concentration for MoM-bearings was 123.7 ± 96.8 ppb and 1078.2 ± 1267.5 ppb for the revised fractured CoC-bearings.

We recommend not to use a metal-based articulation in the revision of a fractured CoC bearing and suggest close follow-up with yearly blood cobalt concentration controls in patients with a MoM bearing or a revised fractured CoC bearing.

What, Who and How Did Herzen’s Dr. Krupov Treat?
Authors: Zakharov Vladimir
Published: March 2022

The Russian literature was relatively late in heeding attention to the social type of the doctor. Nameless medical doctors gradually appear in the novels of the first half of the 19th century, typically as episodic persons without characters. They are educated and intelligent people, thus pleasant to communicate with, and if necessary, medical help can be obtained from them. One of those who endowed their doctor heroes with names and human characters was A. I. Herzen. His works about Dr. Krupov fostered the subject of medicine in Russian and European literature. They are the legacy of Goethe’s Faust and Lermontov’s A Hero of Our Time. Like Faust, Dr. Krupov is a philosopher who poses global questions, and like Werner, he is an ideologist, a skeptic, a reasoner and a materialist. Krupov’s theory that the world is insane, everyone is mentally ill, and the society, rather than patients, needs to be treated is actually not as unambiguous as it seems, if you believe the opinions of the character himself and the critics who wrote about Herzen’s story. The uncertainty of the author’s attitude to Krupov’s theory endows the text with ambivalence, a certain playfulness. Contradictions of political ideas and the impossibility of their execution are overcome in Herzen’s works about Dr. Krupov by literary means, such as irony, satire, parody. Herzen came to favor literature over medicine in treatment of social diseases.

Published: March 2022

Corona is a single stranded RNA virus contains two subfamilies: Coronavirinae and Torovirinae. Its genome size is very larger and divided into four different strains. First autopsy material is collected from the lung tissue for the detection. The sample then stored in a sterile container at 2-8°C. The samples should be the properly labeled. Birthdate, medical record and name of patient must be mentioned. The initial cases were observed in China, Wuhan. The data collected by WHO from the patient’s admitted in ICU. On the basis of their genetic sequence, detection is done by the antibodies. Lateral immune-flow assay can detect the IgG and IgM antibodies. RT-PCR assays can detect the virus by specific primer and probe designing. Middle East Respiratory Syndrome (MERS) can be detected by real time PCR. X-ray Crystallography and Computed Tomography can be used for this purpose. Different X-rays analysis like inception, Xception and ResNeXt net are proposed for the detection.
Larviculture of the Zungaro jahu (Ihering, 1898)- JAÚ, an endangered species under laboratory conditions
Authors: Pelli Afonso , Lopes JM , Souza F de , Macedo RM , Pedreira MM , Hayashi C
Published: March 2022

Zungaro jahu (Ihering, 1898) is a fish threatened with extinction, according to the Red List of the Ministry of the Environment and Legal Amazon. The objective of this work was to propose a cultivation protocol for the jaú. In the laboratory, 54 larvae were cultured for 15 days. Six specimens of jaú were removed, with a survival rate of 11%. The estimated cost of the experimental unit was USD 62.50. With improvement of the cultivation system, we could achieve survival of 9 fingerlings, one for each experimental unit, at an average cost of $ 1.78 per fingerling. The authors believe that the cultivation of the jaú can be overcome, and they raise some hypotheses to justify the extinction in natural environments. Possible causes include changes in natural systems such as climate change, fishing, predation of juveniles by introduced species, diseases introduced, changes in food chains, limitation or restriction of habitat area, physical changes in the environment (formation of lakes for electricity generation), eutrophication or pollution from different sources. The development of larviculture protocols for this species would be an important tool to prevent the extinction, enabling at least its cultivation in the laboratory.

A simplified settlement prediction method for piled rafts in clay
Authors: Bhartiya Priyanka , Basu Dipanjan , Chakraborty Tanusree
Published: March 2022

A method for the estimation of the non-linear, time-dependent settlement of piled raft foundations (PRFs) embedded in saturated clayey soils subjected to uniformly distributed load under the single-drainage condition was developed. A total of 20 different rectangular PRFs resting on four different types of normally consolidated to moderately overconsolidated clays (overconsolidation ratios of 1, 2 and 5) were analysed to quantify their short- and long-term settlements. Rigorous three-dimensional, elasto-plastic finite-element (FE) analyses were performed with the critical-state-based modified Cam Clay soil constitutive model. Biot's coupled consolidation theory was used to model the time-dependent dissipation of excess pore pressure under the single-drainage condition. The FE analysis results were used to investigate systematically the influence of time and various soil and PRF parameters on the settlement responses of piled rafts. Fitted equations correlating PRF settlements and the degree of consolidation with various influencing parameters were developed. The proposed equations predicted the immediate and primary consolidation settlements and the degree of consolidation with reasonable accuracy and can be used in initial design stages.
Seismic behavior of tiered geogrid reinforced soil (GRS) using treated backfill soil
Authors: Safaee A.M. , Mahboubi A. , Noorzad A.
Published: March 2022

As the use of geogrid reinforced soil (GRS) walls increases, appropriate solutions should be considered to improve their performance. In recent years, wall construction in the multi-tiered configuration has improved both static and post-earthquake behavior, and become an appropriate approach to building high-reinforced soil walls. In addition to the above approach, treatment of the soil used as the wall backfill is also a suitable solution to enhance the wall performance. In this study, a combination of the two above concepts has been employed for better understanding the GRS wall behavior by developing a series of reduced-scale physical models. One-meter-high models in one- and multi-tiered fashion were tested backfilled with untreated and treated (by adding a combination of cement and polypropylene fibers) silty sand mixture. A comparison of the 1g shaking table tests among wall models subjected to seismic waves indicated the influence of the treating solutions on the dynamic response of the walls. The findings suggest that use of the two proposed approaches in the GRS walls construction has a notable effect on the wall stability after construction and during an earthquake. It also improves the essential seismic parameters such as displacement and acceleration responses.
Assessment of wind speed and spatial mapping across the Indian subcontinent
Authors: Ghosh Tamal , Sil Arjun
Published: March 2022

Site-specific assessment of wind speed is essential in analysing the susceptibility of any slender structure. With the increasing number of occurrences of extreme wind events in the Indian subcontinent, a quantitative measure of wind hazard based on recent developments has become the need of the hour for India. The Indian standard (IS 875: Part 3) is a national code for reference to the basic wind speed in India, essentially for infrastructural planning and design of mid-rise to tall structures, and the specified basic wind speeds in the code are computed based on a 50-year return period by using the Gumbel probability distribution. However, recently reported cyclones were extreme wind events that already exceeded the specified value in the code. The Gumbel distribution (type I) is applied in the present study by using the method of moments on the long-term wind data (yearly maxima) considering the past few decades (40 years) available for forecasting the wind speed at different return periods. The Anderson–Darling test results are also accommodated to establish the accuracy of the tail behaviour of the statistical distribution used, where the p-value is found to be less than 0.05. Further, in the present study, a site-specific basic wind speed map is also proposed considering latest event data. Indeed, based on the present study, a 100-year return period for basic wind speed is recommended instead of 50 years to ensure enhanced structural safety and serviceability during the design life.

Bu makalede Arapça’nın geleneksel ve modern şeklinde iki kısma ayrılması ve bu ayrımın Arap olmayanlara yönelik Arapça eğitiminde doğurduğu sorunlarla ilgili araştırma hakkında katılıyorum.

Arap olamayan öğrenciler klasik Arapça’ya yönlendirilerek bu hususta teşvik edilmekte; modern Arapça, kısıtlı günlük diyaloglara hapsedilerek ihmal edilmektedir. Bu çalışma Arapça hakkında yapılan söz konusu taksim anlayışını düzeltmeyi ve modern Arapça’nın yalnızca klasikten bir parça olduğunu ispat etmeyi amaçlamaktadır.

Modern Arapça’nın büyük çoğunluğu aslî lafızlara ve terkiplere dayanır. Tarihe ve edebiyata uzanan kökleri bulunmaktadır. Kur’ân’ı Kerim asırların geçmesine rağmen Araça’yı muhafaza etmiştir. Kur’ân’ın yanı sıra dil ve tefsir sahasındaki eserler de bu dili korumuştur. İletişimde, çocuk programlarında, siyasette, iktisatta vb. toplumun her alanında bu dil örnek teşkil etmiştir.

Kur’ân’ı Kerim dili halen canlılığını korumakta ve günlük hayatta kullanılmaktadır. Nitekim insanlar, kültürel ve medenî gelişmeyi yakalayabilmek için Kur’ân’ın kullandığı dilin tezgâhında yeni kelimeler türetmektedirler.

The effect of impurity carbon and oxygen atoms on the migration rate of the tilt boundaries with the misorientation axis <110> in γ-Fe with fcc crystal lattice was studied by the method of molecular dynamics. Dependences of energy of the considered boundaries and rate of their migration at a temperature of 1600 K on the misorientation angle were obtained. The migration rate of <110> tilt boundaries under the same conditions turned out an order of magnitude lower than the migration rate of <111> and <100> boundaries, which is primarily due to the relatively low energy of <110> boundaries. In addition, the low-angle <110> tilt boundaries are unique compared to other tilt boundaries – grain­boundary dislocations in them are ordinary perfect edge dislocations with even cores that do not contain jogs periodically located on them as in <111> and <100> boundaries. The introduction of impurity carbon and oxygen atoms led to a significant decrease in migration rate of the grain boundaries. The binding energies of impurity carbon and oxygen atoms with grain-boundary dislocations in the austenite were calculated. The obtained values correlate well with the dependences of migration rate of <110> boundaries on the impurities concentration. Effect of impurities on migration of the boundaries in austenite turned out to be stronger than in the previously studied nickel and even more so in silver, which can be explained by the relatively low value of the electronegativity of iron atoms in comparison with nickel and silver. A higher value of the binding energy with dislocations in austenite and, accordingly, a greater effect on the migration rate of grain boundaries were obtained for carbon atoms.
Magnetization of ferromagnetic charge at induction heating
Authors: Levshin G. E.
Published: March 2022

The article presents analysis of magnetization and heating of ferromagnetic charge in crucibles of induction furnaces of two types. In inductor furnaces, the charge is magnetized by a vertical electromagnetic flow, and in electromagnetic furnaces with a curved U-, C-, or O-shaped magnetic circuit (MPr) – by a horizontal flow. Knowledge of these largely general magnetization processes is insufficient. Bi magnetic induction in charge material is rather important. There are difficulties in determining this parameter during magnetization of a single piece of charge and other magnetic quantities associated with it: Bm induction and Nm  strength of the demagnetizing field, N demagnetization coefficient, M magnetization, magnetic permeabilities of μi substance and μt body, km susceptibility, etc. Difficulties increase at magnetization, if it is a porous body with crucible volume of ~V t and a factor of filling with ferromagnetic pieces of this volume of Kv ≤ 0.5. It also creates a demagnetizing field with Bmt induction and Hmt strength. Beyond that, pores have an additional demagnetizing effect. Therefore, the induction Вiт in a porous body is less than the induction Вi in a solid one. To compare magnetization of ferromagnetic charge with horizontal and vertical flows with frequency of 50 Hz, modeling experiments were carried out with the samples of DSL08 unconsolidated shot from high-carbon steel (GOST 11964 – 83) with Kv ≈ 0.53. The samples were placed in the inductor and between the poles of a U-shaped core piece. Induction was measured by a cylindrical and flat probe unit of Sh1-15 militeslameter in air and in the sample. An advantage of electromagnetic furnace over an inductor one is more uniform distribution of Bi induction in charge and its significant excess (1.7 times) over the Be induction in a furnace working cavity, which indicates more efficient use of electromagnetic energy in this furnace during heating. The author proposed to control Вi induction when heating the charge by the ammeter-voltmeter method using measuring coil made of heat-resistant wire.
Producción académica alrededor de los estudios sobre cultivos de uso ilícito en Colombia 2000-2019.
Authors: Chará Ordóñez William Darío , Rodríguez Arango Juliana
Published: March 2022

Objetivo: Revisar sistemáticamente la producción académica sobre cultivos de uso ilícito, erradicación y políticas antidrogas implementadas y mostrar los avances en su estudio. Metodología: Con base en la revisión sistemática se consultaron catálogos institucionales y 3 académicos: Proquest, Jstor, Ebsco. Los criterios de inclusión fueron: trabajos académicos publicados, publicaciones de las dos últimas décadas y que tuvieran como tema de abordaje los cultivos de uso ilícito. Resultados: se identificaron tres líneas temáticas: causas de la siembra de cultivos ilícitos, mecanismos de erradicación y políticas antidrogas implementadas, con lo cual se evidencia en la amplia producción existente, que no es un tema sólo abordado desde la óptica de responsabilidad del Estado o actores armados ilegales, sino también, como un asunto más complejo que vincula procesos culturales, de economía regional y medio ambientales. Conclusiones: Si bien los cultivos de uso ilícito se han configurado como una problemática que persiste, la producción académica en Colombia aún se debate entre los estudios sobre sus impactos, los mecanismos de sustitución eficientes, los balances sobre la efectividad de las políticas de restitución y su impacto en el desarrollo económico y social de país.

Authors: Gutiérrez Portillo Ángel Alejandro
Published: March 2022

Objetivo. Describir y analizar cuál es el contexto social de la ingesta de alcohol, y cuáles son los métodos más populares para su rehabilitación entre la población en México. Metodología. A partir de la experiencia en trabajo de campo, se reflexionó sobre los diversos aspectos que conforman el fenómeno social. Resultados. El consumo de bebidas embriagantes es una práctica cotidiana entre la sociedad en México, aunque varían los patrones de uso, sus funciones individuales, grupales y sociales. De acuerdo con informes oficiales, desde hace dos décadas se ha incrementado la ingesta de alcohol en el país. Para su rehabilitación, la población se ha inclinado por el tratamiento ambulatorio y por el consejero espiritual. Conclusiones. El consumo de alcohol sigue al alza. Ningún método garantiza la rehabilitación del alcoholismo. De los dos métodos más utilizados para la rehabilitación, los juramentos son más eficaces que los grupos de autoayuda y ayuda mutua.
“El bazucazo” : un antecedente histórico de la guerra contra el narco en la corridística mexicana.
Authors: Ramírez Pimienta Juan Carlos
Published: March 2022

Objetivo: Visibilizar la importancia del género del corrido como mecanismo de análisis social, histórico y cultural del México contemporáneo. Metodología: Con base en una revisión hemerográfica se crearon estrategias de recolección de datos y hechos con relación a diversos enfrentamientos armados, acaecidos a principios del 2005 al sur del estado de Sonora, entre miembros del crimen organizado y policías municipales, estatales y federales, así como elementos del ejército mexicano. Conclusiones: Al cotejar reportes de medios noticiosos con el corrido compuesto por Manuel, se concluye que el corrido “El Bazucazo” es más útil para comprender los sucesos mencionados. El ensayo no propone que los corridos no mientan, ni mucho menos que no exageren, pero sí que dentro de ellos hay contenido importante que no debe ser desechado a priori, sino que debe ser estudiado y tomado en cuenta por aquellos que implementan políticas públicas para combatir la narcocultura y el narcotráfico.

Absorbed power density approach for optimal design of heaving point absorber wave energy converter: A case study of Durban sea characteristics
Authors: Mutombo Ntumba Marc-Alain , Numbi Bubele Papy
Published: March 2022

This work proposes an approach for the optimal sizing of a cylindrical heaving wave energy converter (WEC). The approach is based on maximising the absorbed power density (APD) of the buoy, with the diameter being the decision variable. Furthermore, two types of buoy shapes were compared to get the best option. The two buoy shapes are the cone cylinder buoy (CCB) and the hemisphere cylinder buoy (HCB). The aim was therefore to determine the best shape and as well as the optimal size of the cylindrical point absorber. To validate the approach, the simulation was performed under Durban (South Africa) sea characteristics of 3.6 m wave significant height and 8.5 s peak period, using the openWEC simulator. The buoy diameter range considered was from 0.5 m to 10 m for both shapes. Simulation results revealed that a diameter of 1 m was the optimal solution for both buoy shapes. Furthermore, the APD method revealed that the HCB was more efficient than the CCB. The power density of the HCB was 1070 W/m2, which was almost double the power density of the CCB, while the two shapes present almost the same absorbed power.
