Authors: Tanudjaya Lea Karen , Makarim Chaidir Anwar
Published: July 2021

Construction on the peat soil and alluvial soil will increase rapidly in the future, if we don’t know the characteristics of the soil, construction problems and failures will occur. Peat soil and alluvial soil has a very low bearing capacity, so they have a very large settlement. Alluvial soil and any other sandy soils has a very low bearing capacity, just like peat soil, and sandy soil has a highly potential of liquefaction. This research is to find out whether Sand Compaction Pile method can improve the bearing capacity of the peat and alluvial soil, and prevent liquefaction in sandy soil. In this case study, we only focus to one bore hole that has a peat layer above the alluvial layer and then improve it with Sand Compaction Pile method. Comparing the bearing capacity results, before and after the improving, with Sand Compaction Pile method, we can find out whether the Sand Compaction Pile can be used for the soil improving method on the peat and alluvial soil. Pembangunan di atas tanah gambut dan tanah aluvial akan meningkat secara drastis kedepannya, apabila kita tidak mengetahui karakteristik dari tanah tersebut maka akan banyak masalah da/atau kegagalan konstruksi. Tanah gambut dan tanah aluvial memiliki daya dukung yang rendah sehingga akan mengakibatkan terjadinya penurunan yang besar. Tanah aluvial atau tanah berpasir lainnya juga memiliki daya dukung yang rendah dan kemungkinan potensi terjadinya likuefaksi sangat tinggi. Penelitian ini bertujuan untuk mengetahui apakah dengan metode Sand Compaction Pile (SCP) dapat memperbaiki parameter tanah, meningkatkan daya dukung dari tanah gambut dan tanah aluvial, dan mencegah potensi terjadinya likuefaksi pada tanah berpasir. Studi kasus ini lebih difokuskan terhadap salah satu bor log yang memiliki lapisan gambut yang tebal dan kemudian di perbaiki dengam metode Sand Compaction Pile. Dengan membandingkan hasil dari daya dukung tanah sebelum di perbaiki dan setelah di perbaiki dengan metode Sand Compaction Pile, kita dapat mengetahui apakah Sand Compaction Pile dapat di gunakan sebagai metode perbaikan tanah di tanah gambut dan tanah aluvial.
Sanción moratoria por el pago tardío de cesantías parciales de los docentes y el conflicto de competencias entre especialidad laboral y contenciosa
Authors: Rincón Andrade Diana Marcela
Published: July 2021

La aplicación del artículo 2 de la ley 244 de 1995 modificada por la ley 1071 de 2006 en donde se reconoce la sanción moratoria equivalente a un día de salario por cada día de retraso en el pago de las cesantías parciales o definitivas de los servidores públicos a partir de su reconocimiento, ha tenido diferentes interpretaciones por parte de los jueces de la Republica y ello ha traído como consecuencia que los jueces o bien se declaren incompetentes para conocer sobre la pretensión, o bien nieguen las pretensiones, produciendo un desgaste para los usuarios y un límite al acceso a la administración de justicia.
Se observa que existen procesos que nacieron con la pretensión de buscar la nulidad y restablecimiento del derecho de un acto administrativo y como consecuencia de ello se busca el pago de la sanción moratoria. Sin embargo, en virtud de una sentencia del año 2014 del Consejo Superior de la Judicatura, en donde se menciona que todos los procesos que contengan el pago de tal sanción debe tramitarse como ejecutivo, los juzgados administrativos y el mismo Tribunal administrativo han resuelto declararse incompetentes enviando los procesos a los jugados laborales que tienen la teoría de la no existencia del título ejecutivo, razón por la cual no les queda otro camino que negar el mandamiento de pago o en la etapa de las excepciones, declarar la inexistencia del título.
Otros, en cambio, han optado por presentar directamente la demanda ejecutiva en la especialidad laboral teniendo la suerte ya mencionada. En febrero de este año, el Consejo Superior de la Judicatura, nuevamente replantea su posición unificando los criterios expuestos y dando pautas para orientar a los juzgados en cuanto a su competencia de alguna manera revuelta por el pronunciamiento de tres años antes. En Neiva se ha presentado este fenómeno aunado al hecho de que el Tribunal Superior Sala Civil Familia Laboral, hasta el año 2013, mantuvo la teoría de la existencia del título ejecutivo, dando confianza legítima a los usuarios de la justicia para presentar sus demandas a través del proceso ejecutivo; posición que cambió en ese año, creando precedente para los juzgados laborales del Circuito de Neiva quienes continúan negando los mandamientos de pago.
Aproximaciones históricas constitucionales de la objeción presidencial en Colombia (1810-1886)
Authors: Scarpetta Pizo María Alejandra , Cabrera Guañarita Erik Francisco
Published: July 2021

Múltiples han sido las formas de gobierno que se han desarrollado a lo largo de nuestro trasegar en búsqueda de establecer la que se creyera la más conveniente forma de asociación, a fin de regir los destinos de un pueblo que recién se halló liberado y que buscaba gobernar en beneficio de todos sus habitantes.

 

En cualquiera de las formas en que se organizaron los nuevos estados, mantuvieron firme y clara la idea de la separación de los poderes y de la complementariedad de los mismos, razón por la cual, desde las primeras constituciones, la figura de la objeción presidencial se enmarcó dentro de la función compartida entre el poder ejecutivo y el poder legislativo, en el proceso de formación de las leyes; por esto, no es extraño que su praxis se encuentre en una constante aleación entre este y aquel.

 

El desarrollo del presente artículo tuvo como aliadas principales las casi 35 constituciones que urdieron nuestra historia constitucional. En ellas, al realizar una exploración de carácter  detallada y completa, se logra apreciar el vaivén en el tratamiento que los próceres de la patria, seguido de los constitucionalistas criollos, le impartieron a la figura de la objeción presidencial pues, de acuerdo con lo que se logra extractar, fue de gran importancia el equilibrio o lo que llamaría Motesquieu ‘checks and balances’ entre el poder legislativo y el poder ejecutivo, sin desconocer que en ciertos periodos de la historia el poder judicial contó con un papel protagónico para la formación y posterior expedición, sanción, promulgación, ejecución o simplemente el sellamiento; términos similares utilizados en otrora para significar la puesta en marcha de la ley y su carácter vinculante.

 

Llama la atención como, a medida que se libraban las batallas de tipo jurídico entre los flamantes Estados, se ajustaba la forma de operancia de la objeción presidencial, pasando su actuar por el pueblo como primer constituyente, sucedido a su vez por el poder ejecutivo y no obstante ello, recaer una vez más en el poder constituyente, quien al ceder su soberanía a sus representantes, dispusieron mediante los textos constitucionales adoptar la decisión de compartir la tarea de formación y puesta en vigencia de las leyes entre el poder legislativo -órgano donde por excelencia se origina el debate de orden legal- y el poder ejecutivo,-encargado de dar su aprobación-. Y en la eventualidad en que este último no lo considerara así, fue facultado en todas las constituciones para oponerse a la ejecución de la ley, invocando razones de inconveniencia; grave perjuicio público o inconstitucional, circunstancias en las cuales surgía un abanico de posibilidades a fin de dar curso a la Ley.
Effect of organic manures, PGPR and micronutrients on yield and quality enhancement in ajwain (Trachyspermum ammi L)
Authors: Thanuja G S , Srinivasulu B , Yuvaraj K M , Giridhar K.
Published: July 2021

Experiments were conducted for two consecutive years during 2017-19 to study the effect of organic manures, PGPR and micronutrients on yield and quality of ajwain seed. Farm yard manure (FYM) and vermicompost (VC) were used as organic sources at 50% and 75% recommended dose of nitrogen (RDN) as basal dose. PGPRs namely Azospirillum lipoferum, Bacillus megaterium and Frateuria aurantia were used for seed priming. Micronutrients namely ZnSO4 and Fe2SO4 were applied thrice as foliar application @ 0.5% first before flowering, second at 50% flowering and third during grain formation. The results revealed that highest number of umbels plant-1, umbellets umbel-1, number of fruits umbellet-1, seed yield plant-1, seed yield hectare-1, straw yield, biological yield, test weight of seeds and essential oil yield were recorded with the application of 50% RDN through VC, which was on par with 50% RDN through FYM, seed priming with Azospirillum and foliar application of zinc with respect to their individual effect. Maximum essential oil content, fixed oil content and thymol content were also observed in case of application of 50% RDN through VC, seed priming with Azospirillum and foliar application of zinc individually. Highest Benefit Cost Ratio (BCR) of 3.33 was recorded with combined application of 50% of RDN through FYM along with seed priming with Azospirillum and foliar spray of Zn at 0.5%.
The integrated use of organic manures, PGPRs and micronutrients could also exert significant influence on yield and quality of Ajwain. It was observed that highest seed yield, yield attributing characters and essential oil yield  and quality parameters were recorded with combined application of 50% of RDN through vermicompost along with seed priming with Azospirillum and foliar application of zinc which was statistically on par with application of 50% of RDN through FYM  along with seed priming with Azospirillum and foliar application of zinc.
Biocontrol of Pythium aphanidermatum causing soft rot in ginger with biosurfactant produced by a rhizospheric Bacillus species
Authors: Goswami D , Syiem M B
Published: July 2021

Plant growth-promoting rhizobacteria benefit plants by producing phytohormones and acquiring vital nutrients from soil. They also form a shield against potential phytopathogens with the production of antimicrobial compounds such as bacteriocin, biosurfactants etc. In the present study, among various rhizobacteria isolated from ginger rhizosphere, the isolate identified as Bacillus altitudinis VS7 that showed a potent biosurfactant producing ability in the preliminary tests was selected for the further study. Compositional analyses indicated that the biosurfactant produced by VS7 was a surfactin like compound, a cyclic lipopeptide. In both microtitre plate and mycelium growth inhibition studies, the biosurfactant showed dose dependent antagonistic activities against Pythium aphanidermatum that causes soft rot in ginger. Although there are reports of biocontrol activity of various rhizobacteria against soft rot in ginger, this is the firstinformation regarding biocontrol activity of a biosurfactant produced by the rhizobacterium B. altitudinis VS7 against P. aphanidermatum.

Published: July 2021

Large cardamom (Amomum subulatum Roxb.) is one of the important cash crops of Sikkim and Darjeeling areas of West Bengal. In this study, a fixed plot survey on insect pests of large cardamom was conducted and found that stem borer (Glyphipterix spp., Lepidoptera: Glyphiperidae), shoot fly (Merochlotops dimorphus Cherian, Diptera: Chlororpidae), leaf eating caterpillar (Artona chorista Jordon, Lepidoptera: Zygaenidae) and tea mosquito bug (Helopeltis theivora Waterhouse, Hemiptera: Miridae) are the major pests of the crop. Eco-friendly organic treatments like neem-based oil, petroleum-derived horticultural oil, spinosad and different formulations of entomopathogens were tested against these major insects. Among all, application of spinosad 45 SC @ 0.3 ml L-1 was found effective followed by neem-based oil (Azadirachtin 0.15% EC) 1500 ppm @ 3 ml L-1 at three different time intervals (first application in February-March, second application in June-July and third application in October-November) against all insects. Moreover, entomopathogenic bio-control agents (Bacillus thuringiensis @ 2 ml L-1, Metarhizium anisopliae@ 5 ml L-1 and Beauveria bassiana @ 5 ml L-1) were on par with neem-based oil for the management of stem borer. Considering the economic importance of the crop and absence of valid technology for management of insect pests in large cardamom through organic options, application of either of them could be helpful in organic management of insect pests in Sikkim.
A modified semi-selective medium for isolation and enumeration of Pochonia chlamydosporia (Goddard) Zare & W. Gams
Authors: Rincy M K , Praveena R , Eapen S J
Published: July 2021

Pochonia chlamydosporia, is one of the most promising biological control agents for managing phytoparasitic nematodes. Isolation and enumeration of viable colonies of P. chlamydosporia from soil and other substrates without contamination is a major limitation, when commonly available nutrient media are used. Development of a suitable selective/semi-selective media by incorporating one or more inhibitors of microbial growth can facilitate isolation of the fungus. In vitro studies were carried out to test the compatibility of commonly used pesticides, namely, metalaxyl, metalaxyl-mancozeb, carbendazim, copper oxychloride, and chlorpyrifos with P. chlamydosporia. The fungus showed relatively high tolerance to higher doses of metalaxyl and carbendazim and was used in the modified medium for better suppression of other soil borne fungi. In the present study, Kerry’s semi-selective medium was modified and evaluated by counting the viable fungal propagules in different substrates (rice, farmyard manure, maize, rice bran, barley, and sorghum) and soil artificially inoculated with the fungus. The results showed that the modified Kerry’s semi-selective medium can effectively be used for isolation and quantification of P. chlamydosporia in routine studies.

"Among the troops he chose brave warriors, who were battling through ranks...". On Some Peculiar Aspects of Amir Timur's Tactical Art
Authors: Bobrov L. A.
Published: July 2021

This article revises the peculiarities of Amir Timur's army tactical peculiarities, as well as their influence on the development of martial art of the Muslim East. It is established that Timur effectively used the mobilization potential of his state. The sedentary population of Chorasa and Transoxiana formed the infantry archery units who were taught to fight under cover of large standing shields - chapars. At the same time, loyal nomad tribes were the source of horse cavalry for the Timur's army. The base of battle formation was represented by a tactical "skeleton" formed of forced kanbuls, powerful advance guard and a reserve (that included elite warriors). Such battle formation allowed Timur to effectively face outflanking and frontal attacks of the enemy. Besides, such battle formation also fit for quick shift from defense to massive counterattack, performed by advance guard and kanbuls projected towards the enemy. The vulnerability of weakened flank corps was partially compensated by using infantry archery units with support of dismounted archers. As a rule, massive archery attack stopped the enemy's attack and provided for counterattack. The organizational and tactical autonomy of kul corps, which could embattle independently even if there was a front breakthrough or encirclement, played an important role. Dismounted, enshielded warriors of the corps could repulse the attacks until the deblocking unit approaches. A fast-moving reserve under Timur's personal command could be used for both repulsing an attack and augmenting the advancing troops.
Archaeological monuments of Zangazur (Lachin district)

Published: July 2021

The settlement of people in Lachin district that located in the foothills of the Lesser Caucasus dates back to ancient times. The settlements of the district were built mainly in accordance with tribal relations. The construction of villages in the area was mainly divided into mountainous, foothill, hill-side and plain types according to the relief of the region. On the whole, since Lachin district is located in a mountainous area, the construction of villages here was also different: mainly, the houses in the district were built far apart, mostly scattered; villages with hut dwellings and those with dwellings built compact, closer to each other.

The newly built bines (nomad camps or isolated farmsteads) were named after those who built them first. Although the main occupation of the district population was animal husbandry, they were also engaged in gardening, forestry and beekeeping. Archaeological and ethnographic investigations conducted in the district, clarified that the population were engaged in many handicraft areas (pottery, stone carving, metal working, etc.). At the same time, the settlements, grave monuments, churches and tombs and bridges of the district were comprehensively studied. The district located in a mountainous area, covers one town, one settlement and 125 villages.
Turkish textiles which have been described in paintings of artist Şevket Dağ
Authors: Aytaç A.
Published: July 2021

The perception of painting that started with the Turks, the Gokturks and the Uighurs was expressed mostly in miniature after Islam. There was a false perception that Islam imposed a ban on painting. Therefore, not much painting art was seen in the Ottomans until recently. There are mostly miniature paintings in the Ottomans. The art of painting has developed in the last periods of the Ottoman Empire. One of the most important representatives of that period was Şevket Dağ. She is one of the first graduates of Şevket Dağ Sanayi-i Nefise School. There are no foreign influences in Şevket Dağ's paintings. There are painting techniques in purely national characters. In the article there are five paintings depicting Turkish carpets. Five paintings in which the furniture and architectural features of the period are depicted together with the carpets will be emphasized.
“The Holder of Forty Spears” in the list of Däftär-i Čingiz-nāmä: definition meaning, symbol
Authors: Аgatay О. M.
Published: July 2021

The article explains the meaning of the term “the Holder of Forty Spears” (“қырықсүңгілі”) in a separate list of the Turko-Tatar ChroniclesDäftär-i Čingiz-nāmäat the end of the XVII century. Besides, a trial of identifying some characters was done from the mentioned source as “the Holder of Forty Spears” – Bolat bahadur” and his son “Bek bey” with real historical figures (beks, tribal chiefs) of the Golden Horde at the time of Janibek Khan. In the military history of the ancient settlers of Eurasia and late medieval Turko-Mongol nomadic tribes, spears and lances were one of the main types of weapons of the close combat and their importance was mentioned more than once in the writings. In addition to the basic, functional, combat assignment, spears and lances in the military culture and traditions of the Turko-Mongol nomads of the Great Steppe had a symbolic meaning. A spear, as a means of armament, used in a ram attack and a close combat, evolved into the symbol of statehood in the form of banners, flags, and possessing them equaled the status of “a commander-in-chief” or “a major warlord”. In this regard, by analyzing and taking into consideration continual several century-long military traditions of the steppe nomads, the article implies the word combination “the Holder of Forty Spears” (“қырықсүңгілі”) inDäftär-i Čingiz-nāmäis equal to “Commander-in- Chief Army”, in other words, in our opinion, in this sourcespear-lanceis represented as an abstracted textual symbol indicating “an army”, “a huge troop” and its Holder as “a commander-in-chief”, “major warlord”.

Posterior spinal fusion surgery for congenital scoliosis may cause substantial surgical trauma. Erector Spinae Plane Block (ESPB) can alleviate pain in adults who undergo spinal surgery; however, reports regarding its use in paediatric patients are limited. Here, we report the case of a 2-year-old girl who underwent posterior spinal fusion for congenital scoliosis. The patient initially experienced severe sadness upon separation from her parents; however, after performing various interactive activities, premedication using intranasal dexmedetomidine and midazolam was administered to sedate the patient. Ultrasound-guided bilateral ESPB was applied for perioperative analgesia. The anaesthesiologist identified mild-to-moderate pain during the first 6 days after surgery using the visual analogue scale for pain and Face, Legs, Activity, Cry, and Consolability scale. Therefore, ESPB may provide a satisfactory analgesic effect and help reduce postoperative opioid consumption in children who require spinal fusion surgery.

Authors:   Air Force Dental Centre, Jodhpur, Rajasthan, India, SK Kaushik
Published: July 2021

Background: Oral leukoplakia is defined as a white patch or plaque, which cannot be characterized clinically or histopathologically as any other disease entity and is recognized as a common precancerous lesion of the oral mucous membrane. Definitive management crucial due to its notoriety for recurrences and malignant transformation depending on the anatomic location, clinical features, degree of epithelial dysplasia and causative factors. High power pulse diode laser has some advantages like less pain, swelling, prevention of metastasis, edema, less bleeding and infection. The prime objective of the study was to evaluate clinically and histopathologically the disease course with six monthly follow up. Methods: Thirty cases who had white lesion in the buccal mucosa with positive history of oral tobacco abuse, clinically diagnosed cases of oral leukoplakia confirmed by histopathology were selected for inclusion in the study and treated by LASER. The outcomes after the clinical and histopathologic determinants were processed with standard statistical tests, the results were derived and findings concluded. Results: Cases were distributed as per the size and histopathologic report and LASER ablation was administered Recurrence was noticed in 4 cases (16.6%) after six months follow up. No case transformed to malignancy during the study follow up period. Conclusion: Management of oral leukoplakia prevents not only recurrence and malignant transformation, but also postoperative dysfunction. Laser ablation of tobacco abuse induced leukoplakia is a simple effective and safe alternative to conventional surgical local excision with predictable outcome which can be undertaken as a routine OPD day care set up.

Microalgae are photosynthetic microorganisms with many potential applications in the food, cosmetics, pharmaceutical and environmental industries. Currently, commercial microalgae production remains limited. Therefore, improving the growth and the culture density of the microalgae cultivation is one of the key enablers to open the way to mass production and commercialisation of these microorganisms. The effect of culture pH on the photoautotrophic growth of C. vulgaris over a large range of values has been investigated in pH-regulated cultures. For each microalgae culture, the specific growth rate, the cell density, the chlorophyll content, the intracellular carbon content and the nitrogen source consumption were monitored. Optimal growth and carbon incorporation have been observed at pH of 7.0. The fastest growth rate and highest biomass production of C. vulgaris were 0.074 h-1 and 0.896 g/L respectively. Under these conditions, a maximum carbon content of cells was 49 % (w/w).
Covid – 19: Pandemic, community accountabilities and social responsibilities

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appeared in Wuhan, China in early December 2019. Since then, governments worldwide have undertaken extraordinary steps to contain coronavirus disease- 2019 (COVID-19) disease. The COVID-19 pandemic also influenced the administration of science. The significant effects of the COVID-19 pandemic on biomedical science and the problems for science-intensive institutions posed by the COVID-19 pandemic have been discussed in this article. The article also encompasses what the researchers should do to sustain a certain degree of scientific operation while maintaining the workers and trainees healthy and dedicated. WHO established preliminary recommendations for laboratory evaluation, guidance on the usage of masks during home treatment and in health care facilities as a measure to mitigate the COVID-19 pandemic. Other measures included clinical administration, prevention and monitoring of infections in health care environments, home care for patients with suspected novel coronavirus, risk coordination and community participation and global surveillance. The infected patients were advised to wear masks to reduce the risk of droplet infection. However, there is insufficient evidence of the efficacy on the use of masks, especially when dealing with a pandemic with minimal alternatives. Many measures countrywide have been executed to reduce the influence of COVID-19 pandemic crisis.
On the Buryat-Yakut Ethnic Connections: *J̌imken || *Yemkon, *Žemkon
Authors:   Institute for Mongolian, Buddhist and Tibetan Studies SB RAS, Nanzatov B. Z. , Tishin V. V. ,   Institute for Mongolian, Buddhist and Tibetan Studies SB RAS
Published: July 2021

The article is devoted to the analysis of the Yakut ethnonym *J̌emkon and *Yemkon, which can be identified in the personal onomastics (the name Zhemkon and surname Yemkonov) and derived names of various administrativeterritorial units (Yemkonskaya or Yamkonskaya volost’, Zhemkonskiy nasleg) recorded in the Russian documents. For the first time, the ethnonym becomes known in the documents of 17th century related to the population of the Lena River valley, which later became part of the Kangalasskiy ulus. Later the name was recorded in Vilyuy region. The modern Yakut spelling cöppön, cökpön, cökkön, cömkön reflects a late adaptation in the Yakut environment. In this connection the authors of the article draw their attention to the ethnonym known among the Buryats. It is widespread in different versions over vast territories among several ethnic-territorial groups of the Buryats. It is form Zemχed (letter ǰimked) of the Khori (Qori) tribe Khudai (Qudai). The various forms of the ethnonym and the corresponding eponyms as Yenχen, Zenχen, Ženχen, Žinχen are widely represented both among the Khori (Qori) tribe Galzut (Γalzuud) settled not only among the Khori (Qori) and Aga Buryats, and among the Verkholensk, Ol’khon, and Barguzin ethno-territorial groups of Western Buryats. The analysis shows that the Russian spelling of the Yakut ethnonym could reflect an adaptation of the original variant to be close to the pronunciation of *ǰimken (~ *dʹimken?), which in turn makes it possible to characterize its phonetic appearance as tending to Western Buryat dialects. Therefore, there are reasons to associate the penetration of this ethnonym into the Yakut environment with native speakers of a Western Buryat type language. The etymology of the analyzed name is difficult. Formal analysis of morphology leads to the opinion that the possible reconstructed semantics would be more likely to a personal name or toponym. It is also noted that it is possible to consider the spelling *J̌imken ~ *Yimken as correspond in its Mongolic form to the name known from the sources of the 11th–14th centuries and related to the Turkic tribe Yemäk ~ Yimäk. However, the authors leave this remark only as a hypothesis to be possible for further discussions.
Abstract depiction of human figures in impressionist art and children's picture books
Authors: Dodgson Neil
Published: July 2021

© 2019 The Author The human figure is important in art. I discuss examples of the abstract depiction of the human figure, from both impressionist painting and children's book illustration, and the challenge faced in algorithmically mimicking what human artists can achieve. I demonstrate that there are excellent examples in both genres that provide insight into what a human artist sees as important in providing abstraction at different levels of detail. The challenge lies in the human brain having enormous knowledge about the world and an ability to make fine distinctions about other humans from posture, clothing and expression. This allows a human to make assumptions about human figures from a tiny amount of data, and allows a human artist to take advantage of this when creating art. The question for the computer graphics community is whether and how we could algorithmically mimic what a human artist can do. I provide evidence from both genres to suggest possible ways forward.
Mathematical characterization of Bridget Riley's stripe paintings
Authors: Dodgson Neil
Published: July 2021

I investigate whether mathematical measures can characterize Bridget Riley's stripe paintings. This is motivated by three considerations: (1) stripe paintings are an incredibly constrained art form, therefore it should be relatively straightforward to ascertain whether or not there is a mathematical characterization; (2) Bridget Riley's approach to composition is methodical and thoughtful, so we can assume that her paintings are carefully constructed rather than random and (3) Riley's paintings can appear random on a first glance but have an underlying structure, therefore Riley's works are challenging to characterize because they are close to random while not actually being so. I investigate entropy (both global and local), separation distance and auto-correlation. I find that all can provide some characterization, that entropy provides the best judge between Riley's work and randomly generated variants, and that the entropy measures correlate well with the art-critical descriptions of Riley's development of this style over the five years in which she worked with it. © 2012 Taylor & Francis.
Cornsweet surfaces for selective contrast enhancement

A typical goal when enhancing the contrast of images is to increase the perceived contrast without altering the original feel of the image. Such contrast enhancement can be achieved by modelling Cornsweet profiles into the image. We demonstrate that previous methods aiming to model Cornsweet profiles for contrast enhancement, often employing the unsharp mask operator, are not robust to image content. To achieve robustness, we propose a fundamentally different vector-centric approach with Cornsweet surfaces. Cornsweet surfaces are parametrised 3D surfaces (2D in space, 1D in luminance enhancement) that are extruded or depressed in the luminance dimension to create countershading that respects image structure. In contrast to previous methods, our method is robust against the topology of the edges to be enhanced and the relative luminance across those edges. In user trials, our solution was significantly preferred over the most related contrast enhancement method. © 2014 Elsevier Ltd.
Can local NURBS refinement be achieved by modifying only the user interface?
Authors: Dodgson Neil , Kosinka J
Published: July 2021

© 2015 The Authors. NURBS patches have a serious restriction: they are constrained to a strict rectangular topology. This means that a request to insert a single new control point will cause a row of control points to appear across the NURBS patch, a global refinement of control. We investigate a method that can hide unwanted control points from the user so that the user's interaction is with local, rather than global, refinement. Our method requires only straightforward modification of the user interface and the data structures that represent the control mesh, making it simpler than alternatives that use hierarchical or T-constructions. Our results show that our method is effective in many cases but has limitations where inserting a single new control point in certain cases will still cause a cascade of new control points to appear across the NURBS patch.

Published: July 2021

This study aimed to evaluate the direct current (DC) and alternating current (AC) electromagnetic field (EMF) intensity and distribution of an electric vehicle (EV). The results revealed that the EV generated DC and AC EMFs, which differed depending on the operation (resting, idling, and driving at speeds of 40 and 80 km/h). A correlation was established between the AC and DC components of the EMF, which was approximately 0.5 when idling and 0.8 at speeds of 40 and 80 km/h. The results obtained were below the harmful limit set by regulatory agencies, specifically the International Commission on Non‐Ionizing Radiation Protection (ICNIRP) and the Institute of Electrical and Electronics Engineers (IEEE). To further contribute to this field of study, the various measurement equipment used in the literature are summarized according to their parameters.

Published: July 2021

The COVID-19 pandemic has changed people’s lifestyles and catalysed digital platform adoption, including within the context of the food delivery business. During the COVID-19 pandemic, food delivery mobile applications gained numerous new users, with the industry being one of the few domains to have leveraged the pandemic’s outbreak. This study investigates the factors that have influenced the adoption of food delivery mobile application technology during the pandemic in Thailand. The research model was adopted from the Unified Theory of Acceptance and Use of Technology (UTAUT) model, integrating perceived fear of COVID-19. Empirical research was conducted using data from 223 food delivery mobile application users in Thailand, with Structural Equation Modelling used to validate the model and analyse the hypotheses. The results indicate that the intention to use food delivery applications was significantly influenced by social influence, performance expectancy, effort expectancy, and perceived fear. Facilitating conditions significantly impacted actual usage behaviour, with moderating results revealing a stronger influence on behaviour intention of perceived fear of COVID-19 among females than males and among younger respondents than older respondents. The variance explained by the modified UTAUT model for intention to adopt food delivery mobile application technology was found to be 59.4%. This research makes a significant contribution to the literature in terms of validating a theory-driven framework that emphasizes the factors which impact the adoption of food delivery mobile application technology in the context of the COVID-19 pandemic. Doi: 10.28991/esj-2021-SPER-08 Full Text: PDF

The purpose of this study was to identify the important graduate attributes in computing disciplines perceived by lecturers of the three sectors of Nigerian Higher Education Institutions (HEIs) desirable for entry into computing profession in Nigeria. The descriptive survey research design was adopted. Fifty (50) academic staff of computer related disciplines from each of the HEIs sectors (Universities, Polytechnics and Colleges of Education) in the North-Central Nigeria were screened and used through convenience random and purposive sampling methods. The Computing Disciplines’ Graduate Attributes Scale (CDGAS) (r = 0.82) was the research instrument used in gleaning the field data. Four research questions were raised and one hypothesis formulated, tested and analyzed using Analysis of Variance (ANOVA) statistical package. The findings identified 13, 17 and 16 important graduate attributes desirable to prepare graduates from Nigerian Universities, Polytechnic and Colleges of Educations (COEs) respectively for entry into computing profession. Common amongst the identified graduate attributes are: collaboration and teamwork, lifelong learning skills, cognitive ability and practical skills, effective communication skills and leadership quality. Also, result from hypothesis testing showed a significant relationship amongst the identified graduate attributes in computing discipline in all sectors of HIEs in Nigeria. (F = 0.610; Critical Value = 3.12; P < 0.05). Conclusively, the study recommended that career development support efforts should be included in the curriculum, which will focus on helping prospective graduate in computing related discipline on their academic abilities, personal qualities and skills.

Noise pollution contributes to environmental degradation and poses a threat to human and terrestrial lives. Noise pollution can be regarded as environmental noise and the propagation of noise may develop a harmful impact on the activity of human or animal life. This study was conducted to determine the influence of environmental factors and its associated health risks of noise pollution in Owerri Metropolis, Nigeria. The study employed a cross sectional descriptive research design. Measurement of noise levels was carried out at 24 different locations. The sampling technique used in this study was a cluster sampling technique. The average reading for each location and each ward were calculated. Also, 900 respondents comprising adults who live and/or operate in the areas were interviewed on the health risks associated with noise, using structured and standardized questionnaire. The results obtained showed that the computed average noise level at the 24 different locations ranged from 79.4 – 95.8dB, and all of which were significantly (P<0.05) above the acceptable standard ranges of <80dB, thereby rating the noise level not acceptable because they can be capable of causing discomfort and pains in man. Influence of environmental factors on noise pollution; 29(3.2%) reported heavy vehicular traffic plying residential areas contributed to noise generation, 33(3.7%) said indiscriminate blowing of siren. Perceived health risks were reported as 47(5.2%) disturbs sleep, 24(2.7%) causes annoyance, 41(4.61%) causes headache and 21(2.3%) interference with conversation. In conclusion, environmental factors, poor education and lack of enforcement of the laws influence noise generation and there is need to check the level of noise pollution in Owerri Metropolis.

Sweet potato (Ipomoea batatas L.) is the most grown storage root crop in Eswatini. However, its storage root yield is low among smallholder farmers partly due to use of inappropriate varieties and agronomic practices such as planting method. Thus, a field experiment was conducted at the University of Eswatini, Faculty of Agriculture, Luyengo, during 2019/2020 cropping season to determine the effects of planting method on growth and yield of the three sweet potato varieties. Two planting methods, namely horizontal and vertical; and three sweet potato varieties, namely Kenya-white, Ligwalagwala and Lamngititi were evaluated in a factorial arrangement in randomized complete block design in three replications. Results showed non-significant difference between the planting methods in most growth and yield parameters recorded for the sweet potato varieties. However, the vertical method of planting had relatively higher vine length, number of branches, mass of storage roots and storage root yield than the horizontal method. On the other hand, there were significant (P<0.05) differences among the sweet potato varieties for most of parameters recorded. The sweet potato variety Ligwalagwala had the highest vine length, number of storage roots per plant (6.47), mass of storage roots per plant (1137 g) and storage root yield (12.01 tonnes/ha). Thus, either horizontal or vertical method of planting and variety Ligwalagwala can be used to increase the productivity of sweet potato in the study area.
