Published: December 2020

Thiết bị đo độ độ mặn online cho môi trường nước là một trong những thiết bị rất quan trọng trong việc giám sát và quản lý môi trường nước cho các trang trại nuôi trồng thủy hải sản. Yếu điểm của các thiết bị đo độ mặn hiện đang được dùng hiện nay trên thị trường là sử dụng phương pháp tiếp xúc trực tiếp qua màng trao đổi ion với môi trường nước thông qua các điện cực cảm biến. Với phương pháp này, theo thời gian, các điện cực sẽ bị bám màng bẩn và bị ăn mòn điện cực gây ra sai số lớn cho phép đo. Để khắc phục nhược điểm này, chúng tôi đề xuất một phương pháp hiệu quả hơn để đo độ mặn nước. Phương pháp đề nghị sử dụng cảm biến siêu âm để đo độ cao của phao nổi lên mặt nước, từ đó dùng định luật Archimes để nội suy ra độ mặn. Phương pháp này có đặc điểm là điện cực cảm biến không tiếp xúc trực tiếp với môi trường nước, không bị ăn mòn điện cực, không bị ảnh hưởng bởi cặn bám của môi trường nên có độ bền và độ chính xác cao.

Bài báo này trình bày phương pháp xác định vị trí và công suất tối ưu của nguồn điện phân tán trên lưới điện phân phối (LĐPP) sử dụng thuật toán coyote algorithm (COA). Hàm mục tiêu của bài toán là cực tiểu tổn thất công suất tác dụng trên LĐPP. COA là thuật toán tối ưu tổng quát lấy ý tưởng từ tập tính xã hội của loài chó sói Bắc Mỹ. Trong đó, quần thể sói được chia thành các nhóm nhỏ và mỗi nhóm có cá thể đầu đàn. Sự thích nghi với điều kiện môi trường của sói phụ thuộc vào sói đầu đàn và xu hướng của nhóm. Ngoài ra, giữa các nhóm cũng có sự trao đổi thông tin thông qua việc cá thể sói bỏ nhóm và tham gia nhóm khác. So với các thuật toán khác, COA không cần các thông số điều khiển nên giúp tăng cường sự ổn định và tin cậy khi áp dụng cho bài toán tối ưu vị trí và công suất nguồn điện phân tán trên LĐPP. Hiệu quả của COA được đánh giá trên các LĐPP 33 nút và 69 nút. Kết quả cho thấy, COA là một phương pháp hiệu quả cho bài toán xác định vị trí và công suất DGs trên LĐPP.

Published: December 2020

En Martínez de la Torre, Ver., México, existen 16,115 ha establecidas con cítricos que aún no están en producción y pueden aprovecharse para sembrar frijol como cultivo asociado. El objetivo del trabajo fue comparar el rendimiento y rentabilidad del cultivo de frijol sólo y asociado con limón Persa, así como determinar, que sistema de cultivo, es más eficiente en el uso de la tierra. El experimento se estableció en noviembre de 2017 en tres localidades del norte de Veracruz. En cada sistema de cultivo, el frijol se sembró en franjas y ocupó una superficie de 216 m2. Se delimitaron cuatro áreas de siembra de frijol de 6 m2 cada una, por sistema de cultivo, en las que se cuantificaron diferentes variables agronómicas, incluido el rendimiento de grano, las cuales se analizaron en diseño experimental completamente al azar con cuatro repeticiones, considerando los valores de las variables obtenidos en cada área delimitada como una repetición. Para la separación de promedios se aplicó la DMS al 5%. También se realizó un análisis de relación beneficio-costo y se obtuvo el índice equivalente de la tierra (IET). Con el sistema de cultivo de frijol asociado con limón Persa, se obtuvo un rendimiento promedio de 1430.7 kg ha-1, significativamente superior al que se produjo en monocultivo. También se obtuvo una utilidad neta por hectárea, 52.3% superior y la mejor relación beneficio-costo, además de una mayor eficiencia en el uso del terreno (IET de 1.23), que cuando el frijol se estableció en monocultivo.
The Question of the “Divine Status” of the Davidic Messiah
Authors: Zehnder Markus 
Published: December 2020

Abstract
This article addresses the question whether there are compelling reasons that suggest that the Davidic messiah in the Hebrew Bible must be a divine being, as opposed to having merely a human-heroic status. It presents a number of arguments that support a divine understanding in some of the texts that can be related to the expectation of a future Davidic messiah. It also draws attention to the fact that in many instances the divine interpretation of the relevant texts is possible or likely rather than necessary and that it is only the combination of a number of suggestive passages that allow the reader to discern the divine character of the Davidic messiah. The investigation is located in the broader context of the question of monotheism in the Hebrew Bible and draws some conclusions concerning the theological consequences of the affirmation of the divinity of the Davidic messiah.
Onomastics and Numerical Composition in the Genealogy of Matthew
Authors: Bryan Steven M. 
Published: December 2020

Abstract
It has long been speculated that Matthew made use of the numerical values of the Hebrew letters of David’s name in structuring his genealogy. This article proposes criteria for discerning numerical composition and shows that Matthew sees numerical significance not just in the name David but in each of the key figures that fall at the junctures of the genealogy: Abraham—David—Jeconiah—messiah. These are the genealogical terms that evoke the themes that Matthew will develop in narrating the identity of Jesus and his messianic people. To highlight these four figures, Matthew has calculated the numerical values of all the names in his list, using a discernible rationale to adjust a handful of names. The literary effect he achieves imbues the 3 × 14 scheme with a heightened sense of divine purpose.
Identification of &#39;Defects&#39; in Epoxy Matrix Composites and Carbon Fiber by Ultrasound. Interaction of the Ultrasonic Beam with the Material
Authors: Sanglier Gaston , Lopez Eduardo J. , Cesteros Sonia , Gonzalez Roberto A. 
Published: December 2020

Non-Destructive Testing (NDT) methods, and especially, ultrasounds have gone from being a mere laboratory curiosity to an indispensable tool in the industry as a primary means of determining the level of quality achieved in its products (ASM, 1989; Barbero, 1999).
This study will identify and apply the main physical phenomena of interaction of an ultrasonic wave in a composite material, to see if through this type of waves, you can detect defects of the type of porosity or delaminations in these materials. The percentages of reflected and transmitted waves in real cases of defects in the composite material will also be studied. It will be shown if the frequencies and intensities of the waves are adequate to find this type of defects or imperfections in the material.
The theoretical study of the ultrasonic wave seeks to help researchers in the development of equipment that uses the methodology of immersion ultrasound for the inspection of materials in the search for &#39;defects&#39; and to understand the physics of the test.
Enfermedad animal, zoonosis y 'One Health': lo que hemos aprendido los veterinarios a lo largo de la historia
Authors: Pumarola Batlle Martí 
Published: December 2020

La pandemia de COVID19 ha puesto en evidencia la transversalidad profesional en el ámbito de la salud, cuando médicos, veterinarios, epidemiólogos, inmunólogos, juristas, sociólogos, ambientalistas, políticos, etc. hemos tenido que colaborar para encontrar y aplicar soluciones al problema. A lo largo de la historia los veterinarios hemos aprendido cómo la salud y la enfermedad de los animales repercutían directa o indirectamente en la población humana. Las zoonosis, enfermedades transmisibles de los animales a los humanos, son un buen ejemplo de ello. Utilizando la historia haremos un recorrido de algunos de estos procesos, para ver cómo los veterinarios han actuado, implicándose y colaborando con otros profesionales, para llegar al concepto actual de una única salud ('One Health'). La necesidad de la cooperación multidisciplinar para poder enfrentarnos de forma efectiva a pandemias como la que vivimos en la actualidad resulta fundamental.

Expulsão e retorno: estratégias dos Xavante de Parabubure e de Marãiwatsédé para a demarcação de seus territórios
Authors: Oliveira Natália Araújo de 
Published: December 2020

Os Xavante ou A'uwe (gente), como se autodenominam, é um grupo indígena que pertence a família linguística Jê, do tronco Macro-jê, situados no Mato Grosso. Chegaram ao estado entre 1820-1870 fugindo do contato com os não índios e dali se subdividindo em diferentes regiões do estado, contudo, políticas desenvolvimentistas empregadas a partir do governo Vargas os alcançaram e expulsaram de seus territórios. O presente trabalho tem por objetivo analisar as táticas destes indígenas para retomar seus territórios, em especial a TI Parabubure e a TI Marãiwatsédé. Para tanto, é uma pesquisa qualitativa que faz uso de entrevistas e falas de atores divulgadas em documentários e jornais ao longo do processo. A TI Parabubure foi demarcada no contexto de fim da ditadura militar e, para pressionar o governo, os Xavante iam a Brasília, invadiam os órgãos governamentais e faziam “performances culturais” afim de atrair atenção às suas demandas. Já a TI Marãiwatsédé, que teve sua demarcação estabelecida a partir de várias batalhas judiciais, teve como marco o amparo dos indígenas na lei como sua âncora de convencimento.
On the status of the giant mylodontine sloth Glossotherium wegneri (Spillmann, 1931) (Xenarthra, Folivora)from the late Pleistocene of Ecuador

Published: December 2020

The late Pleistocene mylodontine sloth Glossotherium wegneri (Spillmann, 1931) (Interandean ­region, Ecuador) has been assigned to Glossotherium Owen, 1839 and Oreomylodon Hoffstetter, 1949 (the latter ranked as a subgenus or genus), and synonymized with G. robustum (Owen, 1842). However, the phylogenetic and comparative analyses conducted here, which include previously undescribed remains, strongly suggest specific distinction for G. wegneri and that there is little, if any, support for generic or subgeneric distinction for Oreomylodon. Among the notable features of this species are the ­presence of an internasal element, marked expansion of the rostrum anteriorly, and dorsoventrally and the palatal region transversely, increased separation of the caniniform tooth from the anterior edge of maxilla, increased relative braincase width, relatively enlarged hypoglossal foramen, and greatly elongated zygomatic process of the squamosal. The resulting single MPT recovered a monophyletic Glossotherium, with the following phylogenetic arrangement of the species of this genus (G. robustum + ((G. wegneri + G. tropicorum Hoffstetter, 1952) + (G. phoenesis Cartelle, De Iuliis, Boscaini & Pujos, 2019 + G. tarijense Ameghino, 1902))).
(Agro)ecologia politica dei conflitti per la terra e il cibo in Ecuador
Authors: Giunta Isabella 
Published: December 2020

The contemporary corporate food regime (McMichael 2018) is characterized by reduction of food to commodity, rural-urban divide, profound asymmetries in access to resources (land and water), extractivism in the form of industrial agriculture (Gudynas 2013; Svampa 2019) and processes of accumulation by dispossession (Harvey 2003). In this context, the paper relies on the approach of political agroecology (González de Molina et al. 2019) to retrace the transformation of food conflicts in Ecuador, from traditional land struggles towards a more complex collective action in the name of food sovereignty, which deals with a scenario of recurring economic and ecological crises.
The place of a socio-cultural environment in climate change discourse
Authors: Recha Charles 
Published: December 2020

The significance of climate change is reflected in global level efforts such as Conference of Parties and Intergovernmental Panel on Climate Change reporting. The global level platform develops consensus on evidences and pathways to climate change mitigation and adaptation. Unfortunately, these efforts often lack social-cultural dynamics to climate change. This study adopted a desktop survey to establish the place of socio-cultural dynamics in climate change discourse. In this study, it is argued that socio-economic security and attributes, cultural-orientation and inter-group dimensions are key determinants to implementation of climate change programmes. To successfully design and implement climate change mitigation and adaptation strategies, first address socioeconomic securities of communities, bring on board sub-national considerations and package climate change impacts as a threat to nationalism.
L’ecologia politica come campo di riconcettualizzazione socio-ambientale: governance, conflitto e produzione di spazi politici
Authors: Zinzani Andrea 
Published: December 2020

Relations between human society, nature and the environment have long played a key role in the geographical debate. In this framework, political ecology has become a critical research field integrating heterogeneous theoretical and epistemological perspectives with socio-political and territorial knowledge, practices and experiences. While for a couple of decades this field has played a considerable role in international geographical literature, in the Italian debate it is still marginal. This contribution therefore aims to provide a framework for reflection and synthesis on how political ecology, through concepts and interpretative keys, contributes to re-discussing socio-environmental relations, highlighting their metabolic, political and conflictual nature, and proposing alternative future scenarios. Specifically, in the framework of global environmental governance and the contemporary ecological crisis, the focus is on socio-environmental conflict, in dialogue with post-politics theory, as a process of production of new spaces oriented to the repoliticization of environmental issues, the reconfiguration of socio-ecological relations and the claim of socio-environmental justice.
Sugar Alcohols
Authors: de Cock Peter 
Published: December 2020

AbstractSugar alcohols, or polyols, are carbohydrates. They bear a close relationship to the saccharides from which they are formed by reduction and from which their names are often derived; glucitol (sorbitol), mannitol, isomalt, maltitol, lactitol, xylitol, and erythritol are the most common commercially available polyols. Some occur in nature in small amounts. They are generally produced by hydrogenation or fermentation of saccharides from renewable raw materials. Worldwide consumption of polyols is estimated to be about 1.8 million metric tons in 2020. More than half of that volume is used in foods where polyols are used at high levels as sugar‐free bulk sweeteners (sugar content less than 0.5% based on dry solids) replacing sugars on a weight‐for‐weight basis and at lower levels to perform very specific technical functionalities. Also, more than half of the global polyols consumption relates to sorbitol only, of which about three‐quarters is used in nonfood applications such as in oral and personal care (ie, toothpaste) and as a starting material in the production of, for example, vitamin C, polymers, and surfactants. Polyols are used in pharmaceutical and cosmetic applications mainly for technical functionality such as filler, binder, anticaking agent, stabilizer, texturizer, moisturizer, and humectant.This article provides an overview of the most common polyols; how they are produced; their physical, chemical, sensorial, biological, and nutritional characteristics; properties in food and nonfood applications; and legal aspects associated with their use.
ANA Webinars: implementation of a conference‐based virtual networking event

Published: December 2020

ObjectiveTo describe the design and implementation of a virtual network event at the American Neurological Association (ANA) annual meeting led by the Junior and Early Career Member (JECM) Committee.MethodsWe designed a one‐hour virtual networking session featuring three 15‐minute small group meetings preceded and followed by general remarks. Each small group session consisted of one senior mentor, a junior/early career faculty moderator, and three to four junior/early career mentees. All participants completed an exit survey to evaluate perceived benefit of this event.ResultsWe recruited 103 mentees, 26 moderators, and 26 mentors for the event. Mentees were primarily at the resident training level or above (17% students). 56% of registered mentees, 100% of moderators and 96% of mentors attended the event for a total of 110 participants. Due to mentee attrition, each room contained 2‐3 mentees. 90% of respondents felt the session met their goals very well or extremely well. Further, 99% felt this session was at least comparable to in‐person networking at conferences and 60% felt this session was better than in‐person networking.InterpretationVirtual networking sessions between junior and senior academic neurologists are feasible and are at least comparable to, if not better than, in‐person conference networking. Future events should consider nuanced mechanisms of matching mentors and mentees, inclusion of ad hoc small groups to foster organic networking, and measures to safeguard against mentee attrition. Future studies should evaluate the long‐term benefits of this event to determine if virtual networking should be utilized moving forward.
The Performative is Political: Using Counter‐Storytelling through Theater to Create Spaces for Implicated Witnessing
Authors: Maxwell Christina , Sonn Christopher 
Published: December 2020

AbstractPerformative counter‐storytelling can be a powerful experience for both the artists who create these stories and the audiences who witness them. This study examined audience responses to a counter‐narrative (entitled “AMKA”) performed by Africans in Australia which intended to present more complex, holistic, and strengths‐based representations of their communities than those currently circulated by dominant discourses. Guided by a critical whiteness lens, the study explored how 34 self‐identifying white audience members interpreted the performance and how they questioned whiteness by assuming the role of implicated witnesses. Following thematic analysis of mixed closed‐ and open‐ended post‐performance survey responses, audience members made connections between the content of AMKA and the contemporary political and cultural contexts in which it was performed and began to examine their positions of privilege and power. This study has provided evidence for the potential of political theater in creating spaces of encounter whereby responsible listening positions can be nurtured in the journey toward dismantling personal, and potentially structural, racially‐based injustices.
