Impact of International Migrants’ Remittances on Socio-economic Development: The Case of Hadiya Zone, Hossana Town
Authors: Abide Melese , Boke Negusse
Published: August 2022

Migration and remittances are always going side by side. This is because; most of the migrants are aimed to cross the border of their country by need of better life for themselves and their family, especially in non-developed countries. This study was therefore, aimed to investigate the impact of international migrants’ remittances on socio-economic development at Hossana town. The study was administered by using both qualitative and quantitative approaches to data collection and analysis. Qualitative method was employed with 35 discussants by using purposive sampling technique and quantitative approach employed with 75 informants by using purposive sampling technique. Throughout this study the researchers was used both primary and secondary sources of data through survey, FGDs, in-depth interviews, key informant interviews and non-participant observation. The major findings indicated that international migrants’ remittances have a positive impact for the socio-economic development in the study area unless some limitations. With regards to social base; because of the people indigenous social relationship was less occurred and instead formal ruled based relationship has been dominantly seen. More importantly it has a very clear positive impact on Hossana’s town economic development, but it should need some corrective actions that have to be taken from the concerned individuals. Therefore, the study recommended that governmental bodies and concerned individuals have to: provide awareness creating trainings for local leaders to keep their indigenous social capital, incorporate indigenous culture and cultural values in education curriculum, anticipate remittances senders rate and prepare plan accordingly, providing investment land for returned and remitted groups according to their capital credibility, providing trainings on basic business making principles and entrepreneurship and negotiate with remittance senders seat countries to have legal money transaction channels. And discuss with the remitted and returned migrants to: establish and invest on value added activities, have a confidence to investing on complex business

Manejo de Vía Aérea Difícil en Paciente con Espondilitis Anquilosante. Reporte de caso
Authors: Carrasco Andres , Ramboa Gustavo
Published: August 2022

Introducción: La espondilitis anquilosante es una artropatía que se encuentra dentro del grupo de artropatías seronegativas, siendo la entidad más común y representativa de ellas. Se caracteriza por inflamación crónica del esqueleto axial, con dolor de espalda de tipo inflamatorio y rigidez progresiva. Típicamente se manifiesta en pacientes jóvenes que inician su sintomatología entre los 20 y 30 años. La osificación progresiva en la espondilitis anquilosante envuelve los cartílagos articulares y discos de la columna vertebral, con el desarrollo de puentes óseos entre las vértebras. Esta fusión hace difícil, sino imposible, el abordaje axial para lograr una anestesia epidural o espinal, e incluso una dificultad aumentada del manejo de la vía aérea por la fusión de las vértebras cervicales. Caso clínico: En este reporte de caso se presenta una paciente femenina de 40 años, ya con diagnóstico de espondilitis anquilosante, que acude para una histerectomía total abdominal, que en primera instancia se intenta un abordaje neuro axial fallido y posteriormente se procede al uso de anestesia general con manejo de la vía aérea. Conclusión: La intubación en pacientes despiertos, es un tema ampliamente descrito en la literatura el cual se puede realizar de distintas maneras, en nuestro caso optamos por el uso de bloqueos de la vía aérea superior con posterior uso de fibroscopio para asegurar la intubación endotraqueal.
Trabajo en equipo en el quehacer científico en nuestra región
Authors: Cuero Cesar
Published: August 2022

El grupo de las llamadas enfermedades raras, son denominadas así porque afectan a un número reducido de personas al compararlas con la población general. Hay que tomar en cuenta, que una enfermedad puede ser rara en una región del mundo y ser común en otra. Su número va en aumento, y en la actualidad anda por los siete mil.

A la par de las reconocidas enfermedades raras, encontramos otras que, si bien no son comunes, su incidencia está por encima de las llamadas enfermedades raras. Este es el caso de la enfermedad de Huntington, una afección de tipo hereditario, con baja frecuencia, que ataca las células nerviosas del cerebro, provocando una progresiva degradación de las mismas que se traduce en una afectación en las capacidades funcionales del paciente, llevando a alteraciones del movimiento corporal, del pensamiento y de la conducta.

Lamentablemente, la alteración neurológica antes descrita, que ocasiona esta enfermedad, se presenta con más frecuencia en la gente de edad joven y productiva, que tendrá que llevar esta afectación por el resto de su vida.

Vale la pena destacar que cuando se quiere profundizar en el conocimiento de enfermedades poco frecuentes como la antes mencionada, se apela a la consulta y trabajo en equipo, entre los médicos especialistas, como una manera práctica y efectiva de recoger el mayor número de casos posible. En la patología que nos ocupa, se invitó a participar a todos los neurólogos de Panamá, a través de la Asociación Nacional que los agrupa, asegurándose con ello la mayor cantidad de casos posibles que estaban diseminados en las diferentes entidades de salud que cuentan con este tipo de especialistas. Este accionar dio un fruto permanente, al crearse el Registro Nacional de Enfermedad de Huntington, que continuará captando nuevos casos.

Esta forma de accionar, de trabajo conjunto a nivel nacional, también tiene sus antecedentes en la Región Centroamericana y del Caribe, con esta misma especialidad, ya que liderizada por neurólogos panameños, se han podido llevar a cabo trabajos de investigación en los que se conjunta el esfuerzo de colegas de varios países, lo que conlleva un avance de la ciencia y una proyección ya no regional sino mundial, del quehacer científico del área.

En una región donde la investigación es de por si difícil por varias razones y por ende escaza; estrategias como esta de unir esfuerzos más allá de las fronteras nacionales, representa una herramienta por demás muy valiosa, que muestra que, si se puede llevar a la realidad el trabajo disciplinado en equipo, con una coordinación efectiva, que garantiza el llegar a los resultados deseados.

Beyond lithium-ion batteries: Shaping the transition to sustainable electrochemical energy storage
Authors: Graeber Gustav , Thatipamula Venkata S.
Published: August 2022

The lithium-ion (Li-ion) technology has enabled substantial advances in consumer electronics and electric vehicles (EV). However, beyond-Li-ion (BLI) batteries are emerging as potential solutions to satisfy future energy storage requirements. BLI solutions may include other lithium-based technologies or avoid the use of lithium altogether. Recent predictions suggest that only a fundamental technological change can substantially increase the specific energy, energy density, and power capabilities needed for fast-charging EVs and electrified aviation. This upcoming transition to BLI batteries is a unique chance to consider an important but often overlooked design criterion when determining the best Li-ion successor: sustainability. To date, short-term cost has been the focus of industrial technology development, but factoring in the long-term environmental and societal impact of energy storage solutions could make alternative technologies competitive. In the context of EV adoption, legislation has already shown to have a decisive effect in shaping technological change. Now, where a transition to BLI technologies is upcoming, targeted policies can shape the energy storage market to promote a sustainable future and could help to avoid a potential lock-in on Li-ion. Especially in times of collapsing supply chains and global geopolitical tension, countries with limited access to central raw materials required for certain battery technologies could benefit from intensifying their support for technologies that rely on abundant raw materials and recycled components.

Multigene phylogeny and morphology reveal Ophiocordyceps hydrangea sp. nov. and Ophiocordyceps bidoupensis sp. nov. (Ophiocordycipitaceae)
Authors: Zou Weiqiu , Tang Dexiang , Xu Zhihong , Huang Ou , Wang Yuanbing , Tran Ngoc-Lan , Yu Hong
Published: August 2022

Ophiocordyceps species have a wide range of insect hosts, from solitary beetle larva to social insects. However, among the species of Ophiocordyceps, only a few attack cicada nymphs. These species are mainly clustered in the Ophiocordyceps sobolifera clade in Ophiocordyceps. A new entomopathogenic fungus parasitic on cicada nymphs, and another fungus parasitic on the larva of Coleoptera, are described in this study. The two new species viz. Ophiocordyceps hydrangea and Ophiocordyceps bidoupensis were introduced based on morphology and multigene phylogenetic evidence. The phylogenetic framework of Ophiocordyceps was reconstructed using a multigene (nrSSU, nr LSU, tef-1α, rpb1, and rpb2) dataset. The phylogenetic analyses results showed that O. hydrangea and O. bidoupensis were statistically well-supported in the O. sobolifera clade, forming two separate subclades from other species of Ophiocordyceps. The distinctiveness of these two new species was strongly supported by both molecular phylogeny and morphology.
Luttes juridiques pour la tutelle des écoles d’hydrographie, à l’occasion de l’expulsion des Jésuites, en particulier dans les villes de La Rochelle, Nantes, Rouen et Bayonne (1760-1785)
Authors: Larrieu Pierre-Yves
Published: August 2022

L’expulsion et la dispersion des Jésuites décidées par les Parlements de Paris et des Provinces entre 1761 et 1763, provoquent une désorganisation de la plupart des chaires de mathématiques et d’hydrographie tenues principalement par les jésuites depuis la fin du XVIIe siècle et mises à la charge des municipalités qui les accueillaient. L’Amiral de France, le duc de Penthièvre, profite de la situation pour réorganiser l’enseignement maritime en tentant d’affirmer son autorité sur les écoles d’hydrographie. Mais cette tentative de prise de pouvoir par la force se heurte à la réaction des autorités locales qui souhaitent garder la main sur cet enseignement. Après une série de procès et d’arbitrages entre institutions locales et royales, le duc de Penthièvre parviendra à asseoir les bases d’un modèle unifié de l’enseignement maritime qui sera développé dans les Ordonnances royales de 1765 et surtout celle de 1786 par l’intermédiaire de ses principaux inspecteurs hydrographes, le mathématicien académicien Gaspard Monge et le professeur d’hydrographie nantais Pierre Lévêque.
Des systèmes de signalement du temps aux navires dans les ports français, dans les années 1880. Le cas du port de Bordeaux dans la correspondance de Georges Rayet
Authors: La) Jérôme Noë (de
Published: August 2022

Au XIXe siècle, la connaissance de l’heure à bord des navires est primordiale pour gérer la navigation. Le système de « time-ball », initialement installé dans les ports anglais à partir de 1829, est peu à peu développé dans différents pays. L’un des arguments pour la fondation d’un observatoire astronomique à Bordeaux fin XIXe est la fourniture de l’heure précise aux navires du port. Les lettres de réponse des directeurs des ports français de Cherbourg, Brest, Rochefort et Toulon au directeur de l’observatoire de Bordeaux, Georges Rayet, qui les a questionnés en 1880, donnent une idée pessimiste de l’efficacité des systèmes installés. Finalement, à Bordeaux, le projet s’enlise dans les débats d’une commission faisant intervenir différentes institutions rivales qui ont peur de perdre leurs prérogatives. Entre-temps, l’unification de l’heure en France a fait son chemin avec le développement des chemins de fer. La radio transmission de l’heure à partir de la Tour Eiffel est mise en place dès 1891.
Oxidation Resistant Nickel Aluminide Coating on Niobium Alloy C103 for High Temperature Aerospace Applications
Authors: Zubair Nouman , Ejaz Noveed , Mansoor Muhammad
Published: August 2022

Owing to its fairly higher melting point (2468°C) and superior thermal conductivity, Niobium alloys are rendered as candidate material for high temperature applications, where state of the art Nickel base super alloys cannot be used. Its applications possess wide range of aerospace components mainly encompassing aircraft exhaust chambers, thrust augmenters, rocket engines and other industries such as chemical and petrochemical. The only limitation with niobium alloys is their inferior oxidation resistance, which can be tackled by developing a high temperature oxidation resistant coating. In this regard, Nickel Aluminide (NiAl) having a melting point of 1638°C embraces a paramount importance amongst the coating categories. In this study, NiAl was synthesized using vacuum melting and strip casting followed by ball milling. The powder was coated on C-103 Niobium alloy specimens using air plasma technique and evaluated for high temperature stability. It was deduced that the coating was exceptionally stable up to 1234 °C in ambient conditions.

Chronic Serotonin Toxicity in the Older Patient With Polypharmacy
Authors: Schuh Michael J.
Published: August 2022

Clinical pharmacists with experience may identify prescribing patterns resulting in iatrogenic disease, which is commonly encountered in geriatric populations where polypharmacy is common. Serotonin toxicity is one toxidrome clinicians may identify, where specific medications are used
in treatment. As a result of their pharmacology training, pharmacists may identify toxidromes caused by medications that other clinicians may overlook. Pharmacogenomic (PGx) testing can provide added insight into a potentially iatrogenic cause for serotonin toxicity, because testing can elucidate
how well an individual patient may metabolize serotonergic medications. Using PGx as a resource in addition to clinical experience, pharmacists can better guide therapy in the geriatric, polypharmacy population to avoid serotonin toxicity.

Published: August 2022

The study was conducted to test the toxicity of Indigofera tinctoria on the antioxidative status and heamatology of Clarias gariepinus. Matured leaves of I. tinctoria were collected, dried, and pulverized. Graded levels of the I. tinctoria leaf powder were weighed and dissolved in 250 ml of water. Data obtained was subjected to one-way to analyse the significant differences between groups and significance level of P<0.05 was used for all tests. Hematological indices indicated a significant (P<0.05) decreasing trend in the red blood cell, haemoglobin and the packed cell volume with increasing concentrations of I. tinctoria while the white blood cell counts increased with increasing concentrations of the toxicant. Stress levels inflicted by the test plant were assessed by estimating the effects on the oxidative stress biomarkers in the kidney, liver, muscle and gill of C. gariepinus. After the 21 days exposure, activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), and catalase (CAT) were investigated and all increased when compared to control. The findings revealed that the disposal of leaves, and effluent from I. tinctoria could threaten the life and existence of the aquatic organism.

Published: August 2022

Waste materials are of major concern around the globe. This study aimed to utilize the scales of fish (Labeo rohita) in microbe-mediated gelatin extraction. Three bacterial isolates were isolated from the fish scales and one bacterial isolate FSW3 showing maximum gelatin yield (61.4 %) was subjected to further analysis. The bacterial culture FSW3 (identified as Staphylococcus spp.) with enhanced production of extracted gelatin was set for physiochemical testing, FTIR analysis, UV-Vis spectroscopy, and stereomicroscopic analysis. The extracted gelatin was successfully utilized in various applications including plant growth promotion under salt stress, anti-adhesion films, firmness of yogurt, biodegradable plastic, and anti-microbial food coatings. Results showed that 0.01 mM gelatin promoted plant growth promotion under salt stress. FSW3 extracted gelatin decreased the 2-fold biofilm-forming ability of E. coli, when exposed to the gelatin-based anti-adhesion films coated on a glass slide and polystyrene sheet. The gelatin showed promising findings as anti-microbial food coatings for tomatoes preservation after 21 days and helpful in the firmness of yogurt. Another advantage of gelatin was casting it into biodegradable plastic. The current study provides a promising approach for fish scales microbe-mediated gelatin extraction and uses it to explore new avenues in biotechnology and microbiology.

Experimental and Numerical Study on the Effect of Nitric Oxide on Autoignition and Knock in a Direct-Injection Spark-Ignition Engine
Authors: Kim Namho , Singh Eshan , Sjöberg Magnus , Saggese Chiara , Matsubara Naoyoshi , Yokoo Nozomi , Nakata Koichi
Published: August 2022

Nitric Oxide (NO) can significantly influence the autoignition reactivity and this can affect knock limits in conventional stoichiometric SI engines. Previous studies also revealed that the role of NO changes with fuel type. Fuels with high RON (Research Octane Number) and high Octane Sensitivity (S = RON - MON (Motor Octane Number)) exhibited monotonically retarding knock-limited combustion phasing (KL-CA50) with increasing NO. In contrast, for a high-RON, low-S fuel, the addition of NO initially resulted in a strongly retarded KL-CA50 but beyond the certain amount of NO, KL-CA50 advanced again. The current study focuses on same high-RON, low-S Alkylate fuel to better understand the mechanisms responsible for the reversal in the effect of NO on KL-CA50 beyond a certain amount of NO. Experiments were conducted to measure the responses of KL-CA50 and trace-autoignition CA50, the latter being indicative of CA50 at which end-gas autoignition starts to become measurable from the apparent heat-release rate. Chemical-kinetics simulations were conducted to reveal the role of NO for end-gas autoignition, with a specific focus on sequential autoignition in a thermally stratified end-gas.

The simulation results reveal that the magnitude of low-temperature heat release (LTHR) generally increases with NO. However, the relative importance of NO for enhancing LTHR diminishes when the LTHR inherent to a fuel’s chemistry is strong, such as at lower temperatures in a thermal boundary layer. This rendered more uniform LTHR within a hypothetical thermal boundary and led to a more sequential (i.e. slower) autoignition event. It was also revealed that a change in compression ratio influences the importance of intermediate-temperature heat release (ITHR) due to changes of the temperature-pressure history of the end-gas. Together with the condition where end-gas autoignition occurs more sequentially, the shorter time spent in LTHR and ITHR regime can counter the increase in autoignition reactivity at high NO levels and allow KL-CA50 to advance.

Published: August 2022

Lean combustion is one of the most applied methods to increase engine efficiency and maintain a good trade-off with engine emissions. The pre-chamber combustion (PCC) is one of the most promising combustion concepts to extend the lean operating limits of the engine. The Narrow throat pre-chamber has shown better lean limit extension compared to other ignition sources. The pre-chamber jets and the main-chamber combustion were studied in a Heavy-Duty optical engine using methane fuel. The tested conditions covered global excess air ratios (λ), between 1.9 to 2.3. The combustion process was recorded using three collection systems: (a) Natural Flame Luminosity (NFL) with a temporal resolution of 0.1 CAD; (b) OH* Chemiluminescence, and (c) CH* Chemiluminescence with a temporal resolution of 0.2 CAD for both. The propagating velocity of the reacting jets was studied using Combustion Image Velocimetry (CIV) based on bottom view images of the main chamber. After the pre-chamber jets ignite the main-chamber charge, a two-stage heat release rate (HRR) was observed for all the tested conditions. None of the three combustion visualizations exhibited a linear correlation with the HRR. The CIV reported high-speed jets penetrating around 400 m/s into the main chamber. The richest case of λ 1.9 presented a higher axial and radial propagation speed than the other cases. The individual vector fields have significant differences with the ensemble average fields, behavior characteristic of a high turbulent process. Finally, the ultra-lean case showed higher vorticity during the pre-chamber discharge, a synonym of high air-fuel entrainment that generates heavy waviness on the flame front. This heavy waviness generates local/partial or total extinction, resulting in abnormal combustion cycles.

The approach is qualitative, Diet Quality Index (DQI-I) instruments is used for kenyang diet and low-energy diet consumers. Kenyang diet and the low energy diet have different characteristics from qualitative and quantitative aspects. Kenyang diet has the principle of natural food ingredients without processing and elimination of food additives. In comparison, the low-energy diet focuses on consuming foods low in energy, high in protein, sufficient in fat, and high in fiber. The composition of the kenyang diet obtained was 22% protein, 45% fat, and 35% carbohydrates from the total energy intake. Compared to kenyang diet, low-energy diet meets a balanced nutritional composition. Processing the menu in kenyang diet and low-energy diet has differences in frying technique. Kenyang diet as a qualitative diet has advantages and disadvantages in terms of nutrition and health. Consumption of natural foods and avoiding processed foods is a good health approach. Kenyang diet uses mindful techniques as the initial stage of the diet by giving full attention to what is eaten. However, kenyang diet has a risk of iodine and potassium deficiency due to the absence of consumption of table salt and milk in the long term.
