The changing role of marketing: Digital transformation of marketing
Authors: Robert Storbacka , Anold Kaj
Published: January 2021

Digitalization affects every aspect of a firm’s business model–from front-end to back-office, from how firms create value for their customers to how they capture value– and doing so can reshape every facet of the firm. By adapting their business models to the possibilities of technology, firms are facing an accelerating transformation of their activities, offering new opportunities for “out-of-the-box” development of new processes and tools, which effectively challenge deeply engrained functional silo- based thinking. Despite the ubiquity of digital transformation, much academic research still seems to take a functional view (Verhoef et al. 2019), where information systems look into the development and adoption of specific technologies (Nambisan et al. 2017) or analytics schemes (Davenport and Ronanki 2018), strategic management research focuses on understanding the role of new digitalized business models (Foss and Saebi, 2017), and marketing research focuses on what is generally called “digital marketing” or the development of an omni-channel environment (Verhoef et al. 2015; Lamberton and Stephen 2016; Kannan and Li 2017).

Abstract. The TROPOspheric Monitoring Instrument (TROPOMI) on board the Sentinel 5 Precursor (S5-P) satellite provides methane (CH4) measurements with high accuracy and exceptional temporal and spatial resolution and sampling. TROPOMI CH4 measurements are highly valuable to constrain emissions inventories and for trend analysis, with strict requirements on the data quality. This study describes the improvements that we have implemented to retrieve CH4 from TROPOMI using the RemoTeC full-physics algorithm. The updated retrieval algorithm features a constant regularization scheme of the inversion that stabilizes the retrieval and yields less scatter in the data and includes a higher resolution surface altitude database. We have tested the impact of three state-of-the-art molecular spectroscopic databases (HITRAN 2008, HITRAN 2016 and Scientific Exploitation of Operational Missions – Improved Atmospheric Spectroscopy Databases SEOM-IAS) and found that SEOM-IAS provides the best fitting results. The most relevant update in the TROPOMI XCH4 data product is the implementation of an a posteriori correction fully independent of any reference data that is more accurate and corrects for the underestimation at low surface albedo scenes and the overestimation at high surface albedo scenes. After applying the correction, the albedo dependence is removed to a large extent in the TROPOMI versus satellite (Greenhouse gases Observing SATellite – GOSAT) and TROPOMI versus ground-based observations (Total Carbon Column Observing Network – TCCON) comparison, which is an independent verification of the correction scheme. We validate 2 years of TROPOMI CH4 data that show the good agreement of the updated TROPOMI CH4 with TCCON (−3.4 ± 5.6 ppb) and GOSAT (−10.3 ± 16.8 ppb) (mean bias and standard deviation). Low- and high-albedo scenes as well as snow-covered scenes are the most challenging for the CH4 retrieval algorithm, and although the a posteriori correction accounts for most of the bias, there is a need to further investigate the underlying cause.

Abstract. The Eocene–Oligocene transition (EOT) was a climate shift from a largely ice-free greenhouse world
to an icehouse climate, involving the first major glaciation of Antarctica and global cooling
occurring ∼34 million years ago (Ma) and lasting ∼790 kyr. The change is
marked by a global shift in deep-sea δ18O representing a combination of
deep-ocean cooling and growth in land ice volume. At the same time, multiple independent proxies
for ocean temperature indicate sea surface cooling, and major changes in global fauna and flora
record a shift toward more cold-climate-adapted species. The two principal suggested explanations
of this transition are a decline in atmospheric CO2 and changes to ocean gateways,
while orbital forcing likely influenced the precise timing of the glaciation. Here we review and
synthesise proxy evidence of palaeogeography, temperature, ice sheets, ocean circulation and
CO2 change from the marine and terrestrial realms. Furthermore, we quantitatively
compare proxy records of change to an ensemble of climate model simulations of temperature change
across the EOT. The simulations compare three forcing mechanisms across the EOT: CO2
decrease, palaeogeographic changes and ice sheet growth. Our model ensemble results demonstrate
the need for a global cooling mechanism beyond the imposition of an ice sheet or palaeogeographic
changes. We find that CO2 forcing involving a large decrease in CO2 of
ca. 40 % (∼325 ppm drop) provides the best fit to the available proxy evidence,
with ice sheet and palaeogeographic changes playing a secondary role. While this large decrease is
consistent with some CO2 proxy records (the extreme endmember of decrease), the
positive feedback mechanisms on ice growth are so strong that a modest CO2 decrease
beyond a critical threshold for ice sheet initiation is well capable of triggering rapid ice sheet
growth. Thus, the amplitude of CO2 decrease signalled by our data–model comparison
should be considered an upper estimate and perhaps artificially large, not least because the
current generation of climate models do not include dynamic ice sheets and in some cases may be
under-sensitive to CO2 forcing. The model ensemble also cannot exclude the possibility
that palaeogeographic changes could have triggered a reduction in CO2.
Last interglacial (MIS 5e) sea-level proxies in southeastern South America

Published: January 2021

Abstract. Coastal southeast South America is one of the classic locations where there are robust, spatially extensive records of past high sea level. Sea-level proxies interpreted as last interglacial (Marine Isotope Stage 5e, MIS 5e) exist along the length of the Uruguayan and Argentinian coast with exceptional preservation especially in Patagonia. Many coastal deposits are correlated to MIS 5e solely because they form the next-highest terrace level above the Holocene highstand; however, dating control exists for some landforms from amino acid racemization, U∕Th (on molluscs), electron spin resonance (ESR), optically stimulated luminescence (OSL), infrared stimulated luminescence (IRSL), and radiocarbon dating (which provides minimum ages). As part of the World Atlas of Last Interglacial Shorelines (WALIS) database, we have compiled a total of 60 MIS 5 proxies attributed, with various degrees of precision, to MIS 5e. Of these, 48 are sea-level indicators, 11 are marine-limiting indicators (sea level above the elevation of the indicator), and 1 is terrestrial limiting (sea level below the elevation of the indicator). Limitations on the precision and accuracy of chronological controls and elevation measurements mean that most of these indicators are considered to be low quality. The database is available at https://doi.org/10.5281/zenodo.3991596 (Gowan et al., 2020).
Glacier Changes in the Chhombo Chhu Watershed of Tista basin
between 1975 and 2018, Sikkim Himalaya, India

Published: January 2021

Abstract. Glaciers of the Tista basin represent an important water resource for mountain communities and large population downstream. The present article attempts to assess the observable changes in the glacier area in the Chhombo Chhu Watershed (CCW) of Tista basin, Sikkim Himalaya. The CCW consists of 74 glaciers (>0.02 km2) with a mean glacier size of 0.61 km2. The change of such glacier outlines obtained from the declassified hexagon KH-9 (1975), Landsat 5 TM (1989), Landsat 7 ETM+ (2000), Landsat 5 TM (2010), and Sentinel 2A (2018). The total glacier area in 1975 was 62.6 ±0.7 km2; by 2018, the area had decreased to 44.8 ±1.5 km2, an area loss of 17.9 ± 1.7 km2 (0.42 ± 0.04 km2 a−1). Debris free glaciers exhibit more area loss by 11.8 ± 1.2 km2 (0.27 ± 0.03  km2 a−1) followed by partially debris-covered (5.0 ± 0.4 km2 or 0.12 ± 0.01 km2 a−1) and maximum debris-covered (1.0 ± 0.1 km2 or −0.02 ± 0.002 km2 a−1) glaciers. The quantum of glacier area loss in the CCW of Sikkim Himalaya took its pace during 2000–2010 (0.62 ± 0.5 km2 a−1) and 2010–2018 (0.77 ± 0.6 km2 a−1) timeframes. Field investigations of selected glaciers and climatic records also support the trend in glacier recession in the CCW due to a significant increase in temperature trend and more or less static precipitation since 1995. Glacier retreat rates in the CCW were almost similar to the Changme Khangpu basin and other selected glaciers in Sikkim Himalaya. This glacier inventory and area change analysis will provide valuable information to the glaciological and hydrological community to model and plan the water resources in the Sikkim state of Eastern Himalaya. The dataset is now available from the Zenodo web portal: http://doi.org/10.5281/zenodo.4457183 (Chowdhury et al., 2021).
Spatially Resolved Infrared Radiofluorescence: Single-grain
K-feldspar Dating using CCD Imaging
Authors: Mittelstraß Dirk , Kreutzer Sebastian
Published: January 2021

Abstract. The success of luminescence dating as a chronological tool in Quaternary science builds upon innovative methodological approaches, providing new insights into past landscapes. Infrared radiofluorescence (IR-RF) on K-feldspar is such an innovative method already introduced two decades ago. IR-RF promises considerable extended temporal range and a simple measurement protocol, with more dating applications published recently. To date, all applications use multi-grain measurements. Herein, we take the next step by enabling IR-RF measurements on a single grain level. Our contribution introduces spatially resolved infrared radiofluorescence (SR IR-RF) on K-feldspars and intends to make SR IR-RF broadly accessible as a geochronological tool. In the first part of the manuscript, we detail equipment, CCD camera settings and software needed to perform and analyse SR IR-RF measurements. We use a newly developed ImageJ macro to process the image data, identify IR-RF emitting grains and obtain single-grain IR-RF signal curves. For subsequent analysis, we apply the statistical programming environment R and the package Luminescence. In the second part of the manuscript, we test SR IR-RF on two K-feldspar samples. One sample was irradiated artificially; the other sample received a natural dose. The artificially irradiated sample renders results, indistinguishable from conventional IR-RF measurements with the photomultiplier tube. The natural sample seems to overestimate the expected dose by ca 50 % on average. However, it also shows a lower dose component resulting in ages consistent with the same sample's quartz fraction. Our experiments also revealed an unstable signal background due to our cameras' degenerated cooling system. Besides this technical issue specific to the system we used, SR IR-RF is ready for application. Our contribution provides guidance and software tools for methodological and applied luminescence(-dating) studies on single grain feldspars using radiofluorescence.
An EMD-PSO-LSSVM hybrid model for significant wave
height prediction
Authors: Tang Gang , Du Haohao , Hu Xiong , Wang Yide , Claramunt Christophe , Men Shaoyang
Published: January 2021

Abstract. Accurate and significant wave height prediction with a couple of hours of warning time should offer major safety improvements for coastal and ocean engineering applications. However, significant wave height phenomenon is nonlinear and nonstationary, which makes any prediction simulation a non straightforward task. The aim of the research presented in this paper is to improve predicted significant wave height via a hybrid algorithm. Firstly, empirical mode decomposition (EMD) is used to preprocess the nonlinear data, which are decomposed into several simple signals. Then, least square support vector machine (LSSVM) with nonlinear learning ability is used to predict the significant wave height, and particle swarm optimization (PSO) is implemented to automatically perform the parameter selection in LSSVM modeling. The EMD-PSO-LSSVM model is used to predict the significant wave height for 1, 3 and 6 hours leading times of two stations in the offshore and deep-sea areas of the North Atlantic Ocean. The results show that the EMD-PSO-LSSVM model can remove the lag in the prediction timing of the single prediction models. Furthermore, the prediction accuracy of the EMD-LSSVM model that has not been optimized in the deep-sea area has been greatly improved, an improvement of the prediction accuracy of Coefficient of determination (R2) from 0.991, 0.982 and 0.959 to 0.993, 0.987 and 0.965, respectively, has been observed. The proposed new hybrid model shows good accuracy and provides an effective way to predict the significant wave height for the deep-sea area.
Extensional reactivation of the Penninic frontal thrust 3 Myr ago as evidenced by U–Pb dating on calcite in fault zone cataclasite

Published: January 2021

Abstract. In the Western Alps, the Penninic frontal thrust (PFT) is the main
crustal-scale tectonic structure of the belt. This thrust transported the
high-pressure metamorphosed internal units over the non-metamorphosed
European margin during the Oligocene (34–29 Ma). Following the propagation
of the compression toward the European foreland, the PFT was later
reactivated as an extensional detachment associated with the development of
the High Durance extensional fault system (HDFS). This inversion of tectonic
displacement along a major tectonic structure has been widely emphasized as
an example of extensional collapse of a thickened collisional orogen.
However, the inception age of the extensional inversion remains
unconstrained. Here, for the first time, we provide chronological
constraints on the extensional motion of an exhumed zone of the PFT by
applying U–Pb dating on secondary calcites from a fault zone cataclasite.
The calcite cement and veins of the cataclasite formed after the main fault
slip event, at 3.6 ± 0.4–3.4 ± 0.6 Ma. Cross-cutting calcite veins
featuring the last fault activity are dated at 2.6 ± 0.3–2.3 ± 0.3 Ma. δ13C and δ18O fluid signatures derived from
these secondary calcites suggest fluid percolation from deep-seated
reservoir at the scale of the Western Alps. Our data provide evidence that the PFT
extensional reactivation initiated at least ∼ 3.5 Myr ago with
a reactivation phase at ∼ 2.5 Ma. This reactivation may result
from the westward propagation of the compressional deformation toward the
external Alps, combined with the exhumation of external crystalline massifs.
In this context, the exhumation of the dated normal faults is linked to the
eastward translation of the HDFS seismogenic zone, in agreement with the
present-day seismic activity.
Observing traveling waves in glaciers with remote sensing: new flexible time series methods and application to Sermeq Kujalleq (Jakobshavn Isbræ), Greenland
Authors: Riel Bryan , Minchew Brent , Joughin Ian
Published: January 2021

Abstract. The recent influx of remote sensing data provides new opportunities for quantifying spatiotemporal variations in glacier surface velocity and elevation fields. Here, we introduce a flexible time series reconstruction and decomposition technique for forming continuous, time-dependent surface velocity and elevation fields from discontinuous data and partitioning these time series into short- and long-term variations. The time series reconstruction consists of a sparsity-regularized least-squares regression for modeling time series as a linear combination of generic basis functions of multiple temporal scales, allowing us to capture complex variations in the data using simple functions. We apply this method to the multitemporal evolution of Sermeq Kujalleq (Jakobshavn Isbræ), Greenland. Using 555 ice velocity maps generated by the Greenland Ice Mapping Project and covering the period 2009–2019, we show that the amplification in seasonal velocity variations in 2012–2016 was coincident with a longer-term speedup initiating in 2012. Similarly, the reduction in post-2017 seasonal velocity variations was coincident with a longer-term slowdown initiating around 2017. To understand how these perturbations propagate through the glacier, we introduce an approach for quantifying the spatially varying and frequency-dependent phase velocities and attenuation length scales of the resulting traveling waves. We hypothesize that these traveling waves are predominantly kinematic waves based on their long periods, coincident changes in surface velocity and elevation, and connection with variations in the terminus position. This ability to quantify wave propagation enables an entirely new framework for studying glacier dynamics using remote sensing data.
Downhole distributed acoustic seismic profiling at Skytrain Ice Rise,
West Antarctica

Published: January 2021

Abstract. Antarctic ice sheet history is imprinted in the structure and fabric of the ice column. At ice rises, the signature of ice flow history is preserved due to the low strain rates inherent at these independent ice flow centres. We present results from a distributed acoustic sensing (DAS) experiment at Skytrain Ice Rise in the Weddell Sea Sector of West Antarctica, aimed at delineating the englacial fabric to improve our understanding of ice sheet history in the region. This pilot experiment demonstrates the feasibility of an innovative technique to delineate ice rise structure. Both direct and reflected P- and S-wave energy, as well as surface wave energy, are observed using a range of source offsets, i.e., a walkaway vertical seismic profile (VSP), recorded using fibre optic cable. Significant noise, which results from the cable hanging untethered in the borehole, is modelled and suppressed at the processing stage. At greater depth, where the cable is suspended in drilling fluid, seismic interval velocities and attenuation are measured. Vertical P-wave velocities are high (VINT = 4029 ± 244 m s−1) and consistent with a strong vertical cluster fabric. Seismic attenuation is high (QINT = 75 ± 12) and inconsistent with previous observations in ice sheets over this temperature range. The signal level is too low, and the noise level too high, to undertake analysis of englacial fabric variability. However, modelling of P- and S-wave traveltimes and amplitudes with a range of fabric geometries, combined with these measurements, demonstrates the capacity of the DAS method to discriminate englacial fabric distribution. From this pilot study we make a number of recommendations for future experiments aimed at quantifying englacial fabric to improve our understanding of recent ice sheet history.

Ritos e violência no Ensino Fundamental
Authors: Miranda Jose Bispo
Published: January 2021

Resumo. O artigo visa explicar o surgimento de comportamentos violentos na escola a partir dos atos aparentemente insignificantes condicionados e gerados pelo mito, pelo ritual e pelo rito. A compreensão da violência na tem sido por fatores econômicos, sociais, culturais e pedagógicos, contudo a proposição deste trabalho modifica esse eixo: os comportamentos dos indivíduos podem ser condicionados por mitos, rituais e ritos da sociedade envolvente. A trajetória desta investigação analítico-empírica tem como referencial as ideias de Campbell, Eliade e Segalen. No campo empírico, os trabalhos de coleta de dados (observação e documentação) foram realizados numa escola municipal; os sujeitos foram crianças e professores do 1ª ao 5º ano do Ensino Fundamental. A análise dos dados ocorreu com base no referencial da antropologia (Campbell, Eliade e Segalen) e pela teorização progressiva. Conclui-se que a percepção de atos sociais condicionados pela lógica ritual da sociedade envolvente pode produzir olhares pedagógicos sobre as crianças nas primeiras séries na Educação Básica e identificá-los como produtores e reprodutores de atos que podem implicar em violência na escola e, dessa forma intervir de forma propositiva junto à comunidade escolar.

Los entornos intergeneracionales son, sin lugar a dudas, oportunidades de inclusión socialy mecanismos de participación, esencialmente, para la generación adulta mayor, toda vez que llevaconsigo un sin número de experiencias que requieren de un presente incluyente; es decir, abierto alos aportes que ésta población pueda ofrecer a las generaciones futuras. Es así como se destaca laimportancia de identificar espacios que propicien encuentros entre generaciones, con el fin de lograrbeneficios y aportes integrales mutuos; máxime cuando, en nuestro tiempo, los encuentros de este tipo noestán inmersos en un programa específico que se desarrolle para una finalidad concreta. Por el contrario,pueden identificarse actividades que aportan a dicho ejercicio (encuentro intergeneracional) pero sin estar fundamentadas para tal fin. Por lo anterior adquiere importancia mayúscula la sensibilizaciónhacia el imaginario colectivo en torno a la importancia de inmiscuirse en procesos de participación, quegeneren estrategias encaminadas a que los más viejos le aporten al proyecto de vida de generaciones en formación y, a su vez, la persona mayor tenga un envejecimiento con calidad. Es así como las relaciones intergeneracionales permiten, en este sentido, generar no sólo inclusión social, sino retroalimentación entre generaciones que faciliten la interacción entre las mismas y el surgimiento de mecanismos de participación en donde las personas mayores sean las más beneficiadas.
O ROMPER COM SILÊNCIO: CÍRCULOS DE CULTURA DE CONTAÇÃO DE HISTÓRIAS EM UMA ASSOCIAÇÃO DE IDOSOS

Published: January 2021

O silenciamento tem privado os anciãos de intercambiar suas experiências. Percebemos que há um silenciamento dos conhecimentos fundantes dos idosos. Esse silenciamento tem como consequência o não contar, o não narrar suas experiências. Por isso, temos vivido um processo de contações de histórias, análise, debates e vivências no círculo de cultura de contação de histórias, proporcionando um momento de reflexão aos idosos. Para que se reencontrem como criadores de cultura e também com suas experiências fundantes. Os momentos de círculo de cultura de contação de histórias, têm se desenvolvido e se transformando em aprendizado e redescoberta. A história geradora impulsiona outras histórias, conhecimentos e vivencias. A participação no círculo de cultura de contação de história tem se efetivado em possibilidades de re-descoberta da arte da narração de histórias, interação com a história e a vivência do outro. Assim, percebemos que ao reconstruir a sua palavra, reconstrói-se também o mundo de narrador. Estamos vivenciando, um caminho com os idosos no qual o ato de fiar e tecer histórias têm levado os idosos a se reconhecerem como contadores de histórias e romper com a cultura do silêncio provocada pela opressão social.
A EDUCAÇAO DA PESSOA IDOSA UNIVERSITÁRIA E A PEDAGOGIA DE PAULO FREIRE
Authors: Carraro Valéria , Cury Mauro José Ferreira
Published: January 2021

O objetivo deste artigo é tratar de um tema que contribua para o debate acerca da importância do idoso no atual cenário mundial e brasileiro; também se propõe a compreender o sentido da educação na vida do idoso, indivíduo que, após completar 60 anos ou mais, matricula-se num curso de graduação, em instituição de ensino regular e presencial e, durante dois, três, quatro ou mais anos, frequenta as aulas, realiza as atividades acadêmicas e convive em um ambiente com pessoas de diferentes idades/gerações. Busca-se ampliar as informações sobre o envelhecimento com o intuito de contribuir para a atualização do conceito estabelecido no imaginário social do que é velhice. O suporte teórico está baseado no universo do educador Paulo Freire, tendo em vista a ideia de que a educação é libertadora e desafiadora e, para os idosos que ingressam na universidade, mesmo havendo inúmeros desafios decorrentes da idade, os benefícios da aprendizagem são evidentes, já que oportunizam as relações intergeracionais, aquisição de novos saberes e a possibilidade dos idosos vislumbrarem um recomeço de uma nova carreira, de se tornarem novos atores sociais ou, ainda, quem sabe, apenas aproveitarem o tempo para o ócio intelectual. Os desafios e benefícios da educação levarão ao envelhecimento ativo e à conquista da cidadania. Este artigo trata de uma pesquisa empírica, teórica, qualitativa de cunho bibliográfico, que busca nas teorias de Freire e Edgar Morin novas possibilidades conclusivas para a educação da pessoa idosa.
LÍNGUA ESPANHOLA E UNATI/PE: FORTALECENDO LAÇOS DE AMIZADES
Authors: Kunst Marina Holanda
Published: January 2021

Atualmente verifica-se uma mudança significativa no perfil demográfico da população brasileira. O Brasil apresenta, segundo o IBGE, cerca de 9% da população, o que representa 15 milhões de idosos. Pela projeção do mesmo Instituto, o Brasil em 2025 será constituído por 34 milhões de idosos, aproximadamente 15% da população. Segundo o Estatuto do Idoso, Lei 1.0741/03, considera-se idoso, as pessoas com 60 anos ou mais. Portanto, na perspectiva de que todos devem estar preparados para enfrentar e solucionar a problemática do envelhecimento populacional, a Universidade Federal de Pernambuco criou no ano de 2002, a Universidade Aberta de Terceira idade, que representa um espaço de convivência em grupo, com estímulo à participação ativa do idoso, valorização de suas potencialidades e talentos, além de se constituir em um espaço de prática para o estudo do envelhecimento, nas diversas áreas do conhecimento. Assim, neste texto faz-se uma análise histórica da evolução da criação das universidades abertas da terceira idade sob o prisma mundial e brasileiro culminando com a criação da citada Universidade na Universidade Federal de Pernambuco e referenciando os laços de amizades construídos a partir das aulas de língua espanhola. Observou-se, enfim, que foi necessário levar em conta a diminuição da acuidade auditiva, o incômodo ao se expor diante de uma habilidade que não domina, a dosagem das atividades que envolvam oralidade, a tendência do uso da língua materna nas discussões em grupo, o não interesse pela tarefa de casa e o mais importante, o querer manter o contato após as aulas e do curso.
Comparative study of weaning pigs' muscle proteins using two-dimensional electrophoresis
Authors: Akhremko Anastasia , Fedulova Liliya
Published: January 2021

The proteostasis system of animals, including various types of protein modification during the growth stage, leads to an almost incomprehensible number of possible forms of protein, and each can regulate numerous functions. In the presented work, the composition of muscle tissue protein from different portions of piglets was studied to understand the main muscle protein formation. Comparative analysis of weaned piglets' main muscle protein from l. dorsi, biceps femoris, and brachiocephalicus were analyzed using two-dimensional electrophoresis. Changes in the staining intensity of protein fractions inherent in different muscles were revealed. As part of this work, candidate groups of pig muscle proteins have been selected. Eleven protein spots were revealed for the longest muscle of the back, and seven for the biceps; the muscles of the neck are characterized by indicators of low protein fraction volume. Among the proteins found, myosin light chains, phosphoglycerate mutase, troponins, and adenylate kinase is most likely present. The obtained results of protein identification in muscle tissues, obtained during the intensive growth period, will allow a more detailed understanding of protein regulation, function, and interactions in complex biological systems, which will subsequently be significantly important for biomonitoring health and predicting farm animals productivity.

Introduction: We present a patient with carcinoma of the tongue with а lymph node and thyroid metastasеs. The squamous cell cancer of the tongue’s 5-year survival rate has not been improved in the last three decades. Most common sites of metastases are the locoregional lymph nodes, followed by distant pulmonary, liver, bone and skin metastasеs. Only ten cases of metastases to the thyroid gland are reported in the literature. Case report: A 79-year old man presented to the University Hospital in Varna, Bulgaria. Two months before admission, he noticed swelling of the tongue and progressive weight loss. The inspection of the oral cavity revealed a lesion on the left margin of the tongue. A biopsy was performed with a histological result of differentiated squamous cell carcinoma of the tongue. A computed tomography scan of the head and neck region discovered a lesion in the right thyroid lobe. 18-fluoro-2-deoxy-glucose-positron emission tomography imaging showed a metabolically active tumor of the tongue with hypermetabolic metastatic cervical lymph nodes and a zone with abnormally elevated fixation of 18F-FDG in the central part of the soft palate. The described thyroid nodule did not have an increased tracer uptake. It was cytologically assessed after fine-needle aspiration biopsy (FNAB) as a metastasis from squamous cell carcinoma of the tongue. Conclusions: Distant metastases from tongue cancer to the thyroid gland are extremely rare and mostly occur in the advanced stages of malignancy.

Making Cities Resilient in Ghana: The Realities of Slum Dwellers That Confront the Accra Metropolitan Assembly
Authors: Adamtey Ronald , Mensah John Victor , Obeng Gifty
Published: January 2021

Over the past three decades, various countries and stakeholders have aimed at having cities that can better handle natural and human-made disasters, protect human life, absorb the impact of economic, environmental and social hazards and promote well-being, inclusive and sustainable growth. This paper investigates how informal ties result in in-filling and the creation of slums in the context of efforts to make cities resilient in Ghana using the Accra Metropolis as case study. The United Nations Habitat classification of slums was used to purposively select two slum settlements in Accra for the study. The study used mixed methods of quantitative and qualitative approaches to collect data from April 2018 to August 2018. Quantitative data was collected from 400 slum dwellers while qualitative data was collected from eight focus group discussion sessions and in-depth interviews with at least one senior official from related institutions such as Accra Metropolitan Assembly (AMA), Ministry of Local Government and Rural Development (MLGRD), Ministry of Water Resources (MWR), Ministry of Works and Housing (MWH), Ministry of Inner City and Zongo Development (MICZD), Environmental Protection Agency (EPA), Ghana Police Service, and Ghana National Fire Service. Descriptive techniques were used for the analysis. The findings are that informal ties contribute to in-filling in slums. Slum dwellers do not plan to return home, they are not involved in land use decision making and the slums have opportunities and challenges to the slum dwellers and AMA. The AMA should avoid forced eviction of slums and rather enforce development control bye-laws, implement slum upgrading programs, and involve slum dwellers in upgrading programs. Slum dwellers must cooperate with AMA to make Accra resilient. The mainstreaming of the issue of slums in all urban development agendas needs to be given the needed political and policy attention by central government and all stakeholders.

The cultivation of medicinal plants ensured a stable supply of qualitative raw materials in the drug industry. At the same time, it encourages reservation of important and unique resources of medicinal plants. Pharmacognostic characteristics of roots from Astragalus membranaceus (Fisch.) Bge and Astragalus mongolicus Bge cultivated in the Kherlen Bayan-Ulaan, Khentii aimag in Mongolia have been analyzed. Namely, qualitative characteristics of roots were analyzed according to the methods of Mongolian National Pharmacopoeia and the quantity of active compound saponins was analyzed by the spectrophotometric method, including their permissible limits. According to the experiments, moisture in the two roots was determined as 10.0%. Total ash from the roots was 2.38±0.05% in A.membranaceus and 4.18±0.86% in A.mongolicus respectively. Acid-insoluble ash was 0.16±0.04% and 0.28±0.07%, water-extracted compounds were 26.83±0.30% and 37.51±1.62%, respectively, which were assured the standard requirements. The quantity of active compound saponins in the root of A.membranaceus was determined at 0.044±0.009%, while in A.mongolicus 0.028±0.006%. Hence, the root of A.mongolicus contains more water soluble compounds, especially polysaccharides, while A.membranaceus contains more saponin glycosides.
