E-Supplier Management Practices on Supply Chain Performance of Sugar Processing Firms in Kenya
Authors: Biraori Oteki Evans
Published: July 2021

The purpose of this study was to establish the influence of electronic supplier management practices on supply chain performance of sugar processing firms. The target population is 7,584 employees of sugar processing firms in Kenya and Yamane Taro’s formula was applied to come up with a sample size of 379 respondents. Data was gathered by a questionnaire, interviews and observation. Correlation was used to determine the relationship between E-supplier management practices and Supply chain performance while regression analysis tested the hypothesis. The study established that E-supplier management practices enhances supply chain performance. Two kinds of supply chain are proposed; Managerial and demand. Managerial supply chain where as a result of electronic supplier management practice, flow of goods and services from the suppliers are properly managed through information sharing between the buyer-seller thus improved deliveries. Demand supply chain where as a result of electronic supplier management practice, buyers and suppliers tend to develop a single shared forecast of demand and a plan of supply in the sense that buyers issue order for only needed materials from the suppliers and that suppliers fulfills the orders as requested by the buyers. To ensure that the proposed supply chain under e-supplier management,it is recommended that Sugar processing firms’ management should ensure working Websites, working internal and external mail and also provide their suppliers with access credentials to company electronic procurement portal to increase buyer and supplier access to information to enhance E-supplier management practices.
Practical Approaches to Target Detection in Long Range and Low Quality Infrared Videos
Authors: Kwan Chiman , Gribben David
Published: July 2021

It is challenging to detect vehicles in long range and low quality infrared videos using deep learning techniques such as You Only Look Once (YOLO) mainly due to small target size. This is because small targets do not have detailed texture information. This paper focuses on practical approaches for target detection in infrared videos using deep learning techniques. We first investigated a newer version of You Only Look Once (YOLO v4). We then proposed a practical and effective approach by training the YOLO model using videos from longer ranges. Experimental results using real infrared videos ranging from 1000 m to 3500 m demonstrated huge performance improvements. In particular, the average detection percentage over the six ranges of 1000 m to 3500 m improved from 54% when we used the 1500 m videos for training to 95% if we used the 3000 m videos for training.

We introduce in this paper a reliable method for automatic extraction of lungs nodules from CT chest images and shed the light on the details of using the Weighted Euclidean Distance (WED) for classifying lungs connected components into nodule and not-nodule. We explain also using Connected Component Labeling (CCL) in an effective and flexible method for extraction of lungs area from chest CT images with a wide variety of shapes and sizes. This lungs extraction method makes use of, as well as CCL, some morphological operations. Our tests have shown that the performance of the introduce method is high. Finally, in order to check whether the method works correctly or not for healthy and patient CT images, we tested the method by some images of healthy persons and demonstrated that the overall performance of the method is satisfactory.
Contact Angle of Sn-8Zn-3Bi Lead-free Solder Alloy on Copper Substrate
Authors: Duong Ngoc Binh
Published: July 2021

The wettability of Sn-8Zn-3Bi lead free solder alloy on the copper substrate was evaluated via measuring the contact angle of the solder and the substrate. The measured contact angle was then compared to the contact angle of the traditional and widely used eutectic Sn-37Pb solder alloy. Experiments to study the effect of temperature, flux, and surface roughness of the substrate on the contact angle were also carried out. The results show that the contact angle of Sn-8Zn-3Bi on copper substrate decreased as temperature increases. The minimum value of the contact angle obtained was approximately 23° for Sn-8Zn-3Bi. At the same experimental conditions, contact angle of Sn-8Zn-3Bi is higher than that of Sn-37Pb. When three types of fluxes were used, at 230°C, contact angle of Sn-8Zn-3Bi has the smallest value with the MHS37 flux, 25°, and it has the largest value with the zinc chloride flux, 47°. The surface roughness of the substrate has little influence on contact angle of Sn-8Zn-3Bi on copperand the contact angle has changed a few degrees as the roughness changed.

Computer Aided Verification of Voltage Dips and Short Interruption Generators for Electromagnetic Compatibility Immunity Test in Accordance with IEC 61000-4-11: 2004 + AMD: 2017
Authors: Wah Lai Hau , Man Tsui Cho , Wah Li Hing
Published: July 2021

This paper describes a procedure and a computer-aided system developed by the Standards and Calibration Laboratory (SCL) for verification of voltage dip and short interruption generators in accordance with the international standard IEC 61000-4-11:2004+AMD1:2017. The verification is done by calibrating the specified parameters and comparing with the requirements stated in the standard. The parameters that should be calibrated are the ratios of the residual voltages to the rated voltage, the accuracy of the phase angle at switching, and the rise time, fall time, overshoot and undershoot of the switching waveform. A specially built adapter is used to convert the high voltage output waveforms of the generators to lower level signals to be acquired by a digital oscilloscope. The other circuits required for the testing are also provided. In addition, the paper discusses the uncertainty evaluations for the measured parameters.
Validation of the Photometric Method Used for Micropipette Calibration
Authors: Batista Elsa , Godinho Isabel , Rodrigues George , Rumery Doreen
Published: July 2021

There are two methods generally used for calibration of micropipettes: the gravimetric method described in ISO 8655-6:2002 and the photometric method described in ISO 8655-7:2005. In order to validate the photometric method, several micropipettes of different capacities from 0.1 µL to 1000 µL were calibrated using both methods (gravimetric and photometric) in two different laboratories, IPQ (Portuguese Institute for Quality) and Artel. These tests were performed by six different operators. The uncertainty for both methods was determined and it was verified that the uncertainty component that has a higher contribution to the final uncertainty budget depends on the volume delivered. In the photometric method for small volumes, the repeatability of the pipette is the largest uncertainty component, but for volumes, larger than 100 µL, the photometric instrument is the most significant source of uncertainty. Based on all the results obtained with this study, one may consider the photometric method validated.

Accurate Clinical Tympanic Thermometer Measurement System at NMISA
Authors: Kebede Ejigu Efrem
Published: July 2021

Infrared ear thermometers allow users to measure body temperature quickly and non-invasively by inserting a probe into the patient’s ear canal. The effectiveness of tympanic ear thermometers is dependent on how accurate their measurement is. This prompts the demand for accurate and reliable calibration of ear thermometers. Developing capability and providing traceability to the health care facilities in South Africa have become crucial, as there is no calibration laboratory that provides such a service. A standard ear-thermometer black-body source system that is traceable to ITS-90 temperature has been constructed and assembled at the NMISA temperature laboratory. The ITS-90-traceable measurement system developed has a measuring capability of 40 mK (k=2) to 70 mK (k=2) in the temperature range of 35.5 °C to 41.5 °C. At the human body temperature of 37 °C an uncertainty of 45 mK (k=2) is achieved.

Authors: Abian Loreibelle , Caparanga Alvin
Published: July 2021

This paper presents the characterization of the hydrostatic weighing facility of the National Metrology Laboratory (NML) of the Philippines. The study aimed to evaluate its suitability for determination of solid density. It was used to hydrostatically measure the density of a stainless steel (OIML Class F1) test weight weighing 200 g. The measurement result obtained was 7.5827 g cm-3 ± 0.0041 g cm-3 at an approximately 95 % level of confidence. The uncertainty evaluated by the Law of Propagation of Uncertainty (LPU) according to JCGM 100:2008 (GUM) was verified by the Monte Carlo method (MCM), which gave a result of 0.0040 g cm-3. The value determined for the solid density of the sample with its associated expanded uncertainty was found to be within the tolerance interval between 7.39 g cm-3 and 8.73 g cm-3 as required in OIML R111-1 for Class F1 test weights.
Comparison of ice dynamics using full-Stokes and Blatter-Pattynapproximation: application to the central North East Greenland IceStream
Authors: Rückamp Martin , Kleiner Thomas , Humbert Angelika
Published: July 2021

Abstract. Full-Stokes (FS) ice sheet models provide the most sophisticated formulation of ice sheet flow. However, its applicability is often limited due to its high computational demand and its owing numerical challenges. To balance computational demand and accuracy, the so-called Blatter-Pattyn (BP) stress regime is frequently used. Here, we explore the dynamic consequences caused by solving FS and the BP stress regime applied to the central part of the North East Greenland Ice Stream (NEGIS). To ensure a consistent comparison, we use one single ice sheet model to run the simulations under identical numerical conditions. A sensitivity study to grid resolution reveals that velocity differences between the FS and BP solution emerge below ~1 km horizontal resolution and continuously increases with resolution. Generally, BP produces higher surface velocities than FS, at a resolution of 0.1 km up to 5.8 % on average. In an extreme case, estimated ice discharge rates are up to 8 % overestimated by BP; in a rather classical case, BP reveals up to 3 % more ice discharge. Based on these minor model disagreements and given other large uncertainties in ice sheet projections, we conclude that the use of FS seems not an urgent issue and takes a secondary role in narrowing uncertainties of current sea-level projections. However, the englacial advection schemes from both stress regimes indicate severe impacts on internal layers of ice sheets.
Intersections of Memory and History in Rural Hungarian Women’s Life Narratives: Three Case Studies
Authors: Agárdi Izabella
Published: July 2021

The article contextualizes the oral life stories of three Hungarian-speaking women and their connections to the national histories of East-Central Europe. Through these three life narratives, I argue that in reconstructing their own life stories, the women articulate historical change. The women – born in the 1920s in the aftermath of the Austro-Hungarian Empire and coming of age in a socialist Eastern bloc as citizens of different nation-states – make up a generation as well as a mnemonic community with divergent versions of their community’s past. They talk about childhood in the interwar era, their maturation during the Second World War, their married life and work during the early years of socialism and their retirement years after 1989. In so doing, they give shape to starkly different family histories and personal experiences which inform not only their political sensibilities, but also their sense of womanhood, ethnicity, social standing and assessments of the past. While placing themselves into a sequence of events, they maintain their sense of integrity and construct political subjectivities. Their stories are imprints of a deeply divided collective memory of a generation bearing all the complexities that make women’s history different from the mainstream historiographical canon.

La participación ciudadana. Un escenario para la construcción de paz en Colombia
Authors: Giraldo Montoya Gladys
Published: July 2021

Sobre el conflicto en Colombia ya se han escrito muchos documentos que hacen mención a los orígenes, las posibles causas y las consecuencias que ha traído para el país. Pero poco o casi nada se sabe sobre lo que es el posconflicto en el contexto colombiano. Lo que se conoce son las experiencias de los países latinoamericanos y centroamericanos sobre cómo llevaron ellos esta nueva etapa. Lo que se vive hoy en Colombia es la aplicación de la teoría, de lo escrito y de la experiencia que sobre la marcha se vaya logrando. En cuanto a la pertinencia y aplicabilidad de lo que aquí planteamos, se procura que el resultado pueda ser utilizado por la comunidad y sus líderes, así como por las comunidades educativas, esperando que comprendan la importancia de conformar los consejos de participación ciudadana, para utilizar los mecanismos de participación que la ley brinda, y no menos importante, para lograr que se organicen y consigan los objetivos que cada colectivo reclama para su bienestar social y pleno goce de sus derechos.
Dinámicas espaciales de la horticultura en los oasis norte y centro de Mendoza, Argentina
Authors: Carballo Hiramatsu Oscar Alberto
Published: July 2021

La visibilización de la alimentación de las grandes ciudades ha puesto en el foco de las miradas a sus periferias rurales. Frente a la amenaza del avance urbano la producción hortícola a menudo debe relocalizarse hacia zonas más distantes. Sin embargo, bajo esta primera aproximación quedan ocultos otros fenómenos típicos del desarrollo capitalista en el agro. Este trabajo indaga en las dinámicas espaciales de la producción hortícola de Mendoza teniendo en cuenta, además, las reconfiguraciones que implican sobre la producción y sus sujetos. Para ello recurrimos a una combinación de técnicas que incluyen el análisis de datos estadísticos, análisis documental y entrevistas en profundidad. Entre las conclusiones destaca un fenómeno combinado de desplazamiento de la horticultura hacia zonas de la frontera agraria y de concentración de la producción en favor de empresas medianas y grandes especializadas en la producción hortalizas pesadas.

El origen español del término geografía humana. Una programación Docente para opositar a Cátedras (1872).
Authors: Reguera Rodríguez Antonio T.
Published: July 2021

Sobre la idea de que las civilizaciones son espacios se ha construido el discurso de la geohistoria. Trata de entender la humanización de la Tierra apoyada sobre las dos dimensiones básicas de la existencia humana, el espacio y el tiempo. En el pasado más reciente, la humanización se acelera, impulsada por la revolución industrial. Una disciplina académica, llamada Geografía Histórica, ha tratado de entender el mundo y de explicarlo en consonancia con la propias fuerzas que lo transformaban.A este grado de coherencia se le empezó a denominar Geografía Racional, pero el término que finalmente se impuso fue el de Geografía Humana.A conocidos geógrafos europeos se les ha otorgado hasta ahora la preeminencia en el uso del término geografía humana, desde finales del XIX y principios del XX.Pero con el conocimiento de la Programación Docente que un profesor de la Universidad Central de Madrid, Manuel María del Valle y Cárdenas,presentó en 1872 para opositar a una Cátedra de Geografía Histórica, se demuestra que el término se utilizaba en España tres década antes
Movilidad fronteriza, sujetos móviles y multianclados en el acceso de la vivienda. Los casos: Iquique, Alto Hospicio y Antofagasta
Authors: Tapia Ladino Marcela , Contreras Gatica Yasna , Stefoni Espinoza Carolina
Published: July 2021

Desde un enfoque geográfico de la movilidad transfronteriza, este artículo se propone analizar las movilidades fronterizas de peruanos y bolivianos que habitan en las ciudades del norte chileno (Iquique y Antofagasta) y el acceso a la vivienda. Postulamos la tesis que estos sujetos migrantes se mueven en el espacio fronterizo fundamentalmente por razones laborales y por la diferencia ganancial que produce el cruce de las fronteras. Así, la cercanía con el lugar de origen, la posibilidad de ir, venir o quedarse, el ciclo de vida, así como las condiciones de precariedad laboral y de las viviendas a la que ellos y ellas acceden los convierten, en muchos casos, en sujetos móviles y multianclados. La movilidad se aprecia en la capacidad de moverse en la ciudad y el espacio fronterizo y el anclaje se observa a través del sentido que adquiere la vivienda y el acceso a ella. La investigación se sustenta en 16 entrevistas en profundidad realizadas en el marco de una investigación mayor, identificando así, los hitos más importantes en la movilidad y circularidad de los migrantes.

Una lucha sin tregua. Conflictos y disputas entre poder municipal y venta ambulante en el Madrid moderno
Authors: De Miguel Salanova Santiago
Published: July 2021

La ciudad de Madrid se modernizó de manera muy significativa entre 1890 y 1936. Fue un período en el que el mercado laboral se diversificó con claridad, adquiriendo renovados semblantes en sectores tan representativos como el de la distribución comercial. Dentro de este último, la actividad concebida como informal, asociada a la venta ambulante o itinerante, mantuvo una tendencia creciente. Coadyuvó al cumplimiento de unas relevantes funciones sociales entre las clases populares y en determinados espacios urbanos en términos dotacionales. Pese a ello, su incremento generó problemáticas entre quienes se ocuparon del gobierno de la ciudad, que delimitaron sistemáticos intentos de control, reglamentación y restricción con respecto a un escenario concebido como escasamente representativo e incluso desacompasado con respecto a unos nuevos tiempos. Este artículo indaga en la evolución del anterior proceso, enfatizando tanto las políticas progresivamente tomadas por el poder local con respecto a la venta ambulante como las dinámicas de protesta y reivindicación de derechos articuladas por los integrantes de ese sector.

INTERTEXTUALITY IN CONTEMPORARY ART OF KAZAKHSTAN IN THE ASPECT OF CULTURAL MEMORY
Authors: Sharipova D. S. , Kobzhanova S. Zh. , Kenzhakulova A. B.
Published: July 2021

For the masters of modern art of Kazakhstan, along with the importance of samples of classical culture and discoveries of modernist art, Kazakh folk art is becoming a single field of tradition today. Intertextuality, constant dialogue with different layers of world and national painting and sculpture determine the search for new expressiveness in art. This article describes the role of intertextuality in the development of new forms of artistic statements, namely, as in the works of modern Kazakh sculptors (S.Bekbotayev, D.Sarbasov, Z.Kozhamkulov), jewelers (A.Mukazhanov), tapestry masters (A.Bapanov), the importance of the values of native culture as a space of cultural memory is preserved. Experiments with the material are perceived as a ritual, a creative act, a search for their own author's style, modern means of expression of the artist. It is shown that the danger of losing one's own national identity associated with the process of globalization explains the interest of the masters in the author's myth-making, designed to awaken the spiritual foundations of the nation in the minds of contemporaries. Through mechanical details, sculptors create new myths in order to streamline the ethical and psychological state of a modern person, while in the works of masters of decorative and applied art, bricolage is practiced as a combination of different materials and textures, meanings and images closest to the construction of a myth.

"Specific" violation of written speech, that is, dysgraphy, is a serious obstacle to the development of the school curriculum by primary school students, which does not allow at a certain point in time to fully master the educational program in a number of academic subjects, so the identification and correction of dysgraphy is one of the urgent problems. The article examines the writing process from a neuropsychological point of view and highlights the special stages of the writing process. The definitions given by the authors in connection with the violation of the writing process are analyzed, the classification of dysgraphy is briefly described, the importance of timely detection of violations of written speech and the development of appropriate correctional work taking into account the neuropsychological approach is emphasized, modern manifestations and promising areas of the study of dysgraphy are considered based on the analysis of theoretical sources. Defining the concept of "innovation", the significance of one of the innovative approaches to the correction of dysgraphy – the use of cerebellar stimulation-is described, that is, the models of performing exercises in the" balametrics " complex are shown. The article describes the methodology and results of the ascertaining and formative experience conducted on the basis of the analysis of errors that occur in the writing of primary school students studying in the Kazakh language.

Brain tumors are a severe form of pathologies, that are more common in children and it is associated with hydrocephali. The long term effects of central nervous system therapy for children with brain tumors have been the subject of research since the 1970. Many studies have demonstrated that children treated for brain tumors with surgery and standard radiation therapy have developed intellectual decline which is progressive over at least a decade. Risk factors for the cognitive deterioration have been identified and include: perioperative complications, hydrocephalus, high radiation dose, large volume radiation, chemotherapy (especially methotrexate), vasculopaty and young age at the time of treatment. The purpose of research: Study of surgical treatment applied to children with brain tumors hydrocephalus by implementing and perfecting the surgical treatment. Material and methods: We used data of 2018-2019 period, in the Children Clinical Hospital „V. Ignatenco”, of the Republic of Moldova, which shows the structure of morbidity through malign and benign tumors with associated hydrocephalus at prematures population. Results: Since 2018-2019 were diagnosed 13 children. The average age was: 1 child(0,76 %) 0-1 years old, 5 children (38,46 %) 2-5 years old, 2 children (15,38 %) 6-10 years old and 5 children (38,46 %)11-17 years old. From 13 children, 2 children (15,38 %) were inoperable. The incidence was 10 boys (76,92%) and 3 girls (23,07%). There were complications: malign hipertermia, anemia, cranial nerves damages (facial asymmetry, palpebral ptosis), hemiparesis, intraventricular bleeding. Conclusions: The morbidity was common in boys, average age was 2-5 and 11-17 years old. Chidrenswere operated in two ways. There were complications since intraoperatory and postoperatory period.

Today, many people worldwide suffer from at least one vascular disease, one of these diseases is the hemangioma. A hemangioma is a vascular tumor which, in many cases, requires surgical intervention. Approximatively 30% of all hemangiomas are visible at birth. It occurs 5 time more often in females than in males, 83% occur on the head and neck area, the remaining 17 % appear throughout to the rest of the body, externally and internally. The biggest problem is the origin of this tumor. Could we understand how a hemangioma forms, we should be able to accelerate its disappearance, or prevent its growth in the first place.

Advanced dental caries is the main cause that leads to tooth loss and extractions, therefore it is important to diagnose and treat this condition on time. Dental caries often differs from other diseases in that it can be diagnosed only when it requires surgical treatment. Detection and treatment of incipient carious lessions is very rare in practice. Radiography is an indispensable paraclinical examination in the detection of carious lesions because a thorough clinical examination is not possible for all dental surfaces. The relief of the occlusal surfaces and the limited access to the proximal surfaces make the detection of carious lesions during a clinical examination very difficult. Numerous clinical studies have shown that a radiological examination can reveal carious lesions that would otherwise remain undetected both in occlusal and proximal surfaces. About 50% of interproximal carious lessions cannot be identified during clinical examination and require radiological investigations.
Electromechanical Optical Mapping of the Heart and Stomach
Authors: Rogers Professor Jack
Published: July 2021

Optical mapping has long been used to image wave propagation in the heart, almost always in ex vivo, motion-arrested preparations. In the past few years, our laboratory has developed methods to optically map beating hearts–both ex vivo, and very recently, in vivo. Epicardial deformation can be imaged at the same time, enabling study of the bidirectional coupling of electrical and mechanical function. We are extending these methods to the stomach to image slow wave propagation and the resulting contractions.
High-Order Implicit Large Eddy Simulation of Flow over a Low-Reynolds Turbine Cascade
Authors: Afshar Nima Fard
Published: July 2021

In the present study scale-resolving simulations of flow over a low-Reynolds turbine cascade are performed using PyFR. Various flow metrics, including isentropic Mach number distribution at mid-span and total pressure loss in the wake are compared against experimental data for two different Reynolds-numbers. The good agreement of th results and experimental data demonstrate the potential of PyFR specially as a GPU-accelerated CFD tool for simulating unsteady flows on unstructured meshes. Moreover a detailed analyze of the influence of turbulent inflow and different Reynolds-numbers on the separation, laminar-turbulent transition and total pressure wake loss is presented.

Competitiveness in the era of globalization is tougher than ever before. Most of small medium-sized enterprises, especially in the manufacturing sector, are easily vulnerable due to lack of opportunities and resources to harness the economics of scale as well as business activities in research and development. To drive business competitiveness, the small and medium-sized enterprises (SMEs) must make use of resource efficiency in production processes and optimize the overall equipment effectiveness (OEE). The method of single minute exchange of dies (SMED) appears to be an effective approach, which does not require financial investments but only utilizes the current human resource, to improve and maximize the OEE. The paper describes the step-by-step approach to apply SMED and shows its results in the increase of 18% OEE in a semi-auto cutting machine.
