Micropropagation of Aloe vera
Authors: Oliveira Almeida Rodrigo
Published: February 2024

Aloe vera is a medicinal plant with several properties and is used in
pharmaceutical, medicinal, biomaterials, food, and cosmetic industries. This plant is
associated with hot climates and dry habitats, with plantlet production based on lateral
shoot propagation, an expansive and slow method, insufficient to meet the increasing
demand of the industry. Therefore, the development of a suitable Aloe vera
micropropagation protocol is crucial, keeping the genetic integrity and providing largescale plantlets production. Nevertheless, parameters like source of plant tissue, surfacesterilization process, culture medium conditions and plant growth regulator
concentration can affect the morphogenic response process. Since all parameters are
defined to obtain the best performance, the micropropagation protocol is suitable to be
used commercially, providing mass production of Aloe vera plantlets with high quality.

Micropropagation and In Vitro Studies in Hedychium J. Koenig (Zingiberaceae)
Authors: Vani S. , Thomas Sinjumol , Mani Bince
Published: February 2024

Hedychium, a tropical to subtropical Asian genus with about 100 species,
has various medicinal and horticultural uses. There is a high rate of exploitation and
disappearance of its species from natural habitats. Additionally, habitat loss and natural
calamities should speed up the erosion of this plant species. Micropropagation is
considered a multiplication and conservation strategy for medicinal plants.
Micropropagation in Hedychium is very scanty, and protocols have been developed
only for less than 20 species so far. Hedychium coronarium and H. spicatum are wellstudied species in vitro among the micropropagated species. It is interesting that
micropropagations through protocorm-like bodies were achieved in H. coronarium.
The selection of explants and their axenic development in vitro is the major hurdle in
micropropagation. Cotyledonary nodes, shoot tip or shoot tip meristems from
axenically germinated seeds, rhizome buds, rhizome meristem, and zygotic embryos
were the explants commonly used for the micropropagation of Hedychium. Various in
vitro methods such as somatic embryogenesis, direct organogenesis and indirect
organogenesis, multiplication through microrhizome induction, and propagation
through protocorm-like bodies were frequently tried for the successful
micropropagation of this genus.

Authors: Kumari Rajani Sarita , Kesh Meena Rishi , Mishra Preeti , Patni Vidya
Published: February 2024

Moringa oleifera Lam. tree is considered a miracle tree due to its nutrientrich profile. This plant has been widely cultivated throughout the world for its
medicinal and nutritional benefits. Moringa plant contains a significant amount of
various phytochemicals such as alkaloids, flavonoids, saponins, tannins, and phenolics
that are responsible for their various medicinal, nutritional, and other applications. The
use of moringa in pharmacological drugs not only increases cultivation but also
increases the over-exploitation of this tree. As the conventional methods of moringa
reproduction are not much effective, we require additional alternative strategies to
multiply moringa plants. Micro-propagation is considered an effective method to
produce a large number of transplants within a short time period. This chapter explores
the micro-propagation approaches of M. oleifera together with its nutritional profile
and biological activities.

Authors: Aswanilal L.V. , Saranya Krishnan S.R. , Siril E. A.
Published: February 2024

Oldenlandia umbellata is an important medicinal herb distributed in the
tropics used in the formulation to treat asthma, bronchitis, bronchial catarrh, snake bite,
and many infectious diseases. The mature roots of O. umbellata are also known as a
source of the natural dye anthraquinone (AQ), the second largest group of textile dye.
However, extraction of the dye contained in the roots of this plant may pose a threat to
its survival in its natural habitat. This chapter explores the scope and relevance of
micropropagation of medicinally and economically significant O. umbellata, thereby
saving this species in the wild and scaling up dye production through in vitro means. In
vitro propagation efforts of this herb were made through axillary bud proliferation
using benzyl adenine and by adding an auxin transport inhibitor, quercetin. A somatic
embryo-based propagation system was also established through an in vitro starvation
method. Based on available methods, O. umbellata can be efficiently propagated and
conserved superior germplasm by applying the most suitable in vitro propagation
methods.

Authors: Kumar Sishu Nayan , Immanuel Selvaraj Chinnadurai , Sankar Parasurama Deepa
Published: February 2024

Glycyrrhiza glabra belongs to the family Fabaceae and is commonly called
licorice. It is an important medicinal plant in Europe, China, and the Mediterranean.
The plant's therapeutic value is also mentioned in Ayurveda and Siddha. Licorice is
cultivated for commercial purposes in many parts of the world because of its economic
value and demand. It is used as a flavoring agent in juices, candies, soft drinks, and
beverages because of its characteristic taste and smell. In addition, it is regarded as a
sweetener and thirst quencher. Licorice contains phytochemicals, and the most
abundant compounds are glycyrrhizic acid, anethole, liquiritigenin, isoliquiritin,
pinocembrin, and licoflavanone. The plant is a good source of antioxidants and exhibits
anti-inflammatory, antimicrobial, antiviral, anti-diabetic, and anti-cancer activity. Even
though it has many health-benefiting features, consuming high amounts of licorice can
lead to hypertension, hypokalemia, and congestive heart failure. Due to its high
demand, good medicinal value, and poorly developed cultivation strategy, researchers
are focusing on different aspects of the in vitro propagation of the plant. Studies have
revealed that micropropagation of licorice has improved the level of secondary
metabolites and high antioxidant properties. Thus, this chapter focuses on the
propagation method of licorice, primarily focusing on micropropagation. Moreover, it
also highlights the phytochemistry and important pharmacological activity of
Glycyrrhiza glabra.

Authors: Bashir Ganie Irfan , Shahzad Anwar , Parveen Shahina , Wasi Adla , Tahseen Sabaha
Published: February 2024

Pterocarpus marsupium Roxb. is one of the important plants of the Fabaceae
family and is present in different regions of the world. It is greatly valued for its
medicinal properties and has often been used for medical purposes. It was observed
that P. marsupium contains numerous phytochemical components, such as glycosides,
proteins, cardiac glycosides, terpenoids, alkaloids, carbohydrates, and flavonoids. Due
to overexploitation, the natural population of P. marsupium is declining steadily,
because of which it is required to be cultivated on a larger scale. The conventional
propagation methods of P. marsupium are time-consuming processes, and the plant is
not easy to propagate through seeds because of its low germination percentage. Hence,
to overcome the problem related to conventional propagation and to reduce the
destruction of plants in wild habitats, tissue culture functions as an important tool to
conserve the plant. The tissue culture practice is extremely useful to meet the rising
demands of the people because it gives a significant number of elite genotype
progenies within a limited time and without seasonal dependence.

Authors: Machemba Sophia Jonathan , Shukla Parag
Published: February 2024

Technology breakthroughs brought unforeseen competition among telecom
operators in Africa. Digitization and digital transformation were the results of the
revolution in technology. The study uses a literature review to discuss the digital
initiative and digital transformation of African telecom operators’ changes and
challenges. Although Africa is still stepping ahead to effectively engage itself in
digitization and technology, especially in the telecommunications industry, the
outcome of digitization is to bring out the company's profit, gain more customers
through experience, and increase efficiency and effectiveness. The results show that
customization, sales optimization networks, single-run access networks, and power
machine learning are positive trends that African telecom operators must focus on to
bring about changes in the telecommunications industry. The managerial implication of
the study is that telecom operators must invest in technology and infrastructure that
facilitate digitization and digital transformation to operate accordingly.
Concatenação de afixos em Bantu: algumas leituras a partir da Fonologia Lexical
Authors: Magona Vasco , Wilson Francelino
Published: February 2024

Bantu languages from Mozambique exhibit a grammatical behavior distinct from Portuguese, from which they coexist. Noun morphology is one of the domains that offers notable differences in functioning between these languages. The object of this work is the affixes in Bantu, i.e., noun prefixes, suffixes and locative circumfixes of Ciyaawo (P21), Xichangana (S53) and Emakhuwa (P31) languages, (Ciyaawo and Emakhuwa) spoken i n t he N orth a nd ( Xichangana) in t he S outh o f the country. Based on the theoretical support of standard Lexical Phonology (Kiparsky 1982 and Mohanan 1982) and the Booij & Rubach (1987) model, we seek to understand the behavior of morphemes that are linked to nominal themes and, with that, determine the occurrence of morphophonological processes and constraints arising from the interweaving between morphology and phonology. The data analyzed were obtained from a personal database built through instruments for collecting basic vocabulary from the Núcleo de Estudos de Línguas Moçambicanas(NELIMO), applied to higher education students, between 2013 and 2017 on one hand, and from two secondary sources (Langa 2012 and Ngunga 2014), on the other hand. The research results seem to confirm the existence of two components of the lexicon, namely, a. the cyclic – where morphological rules act, and b. the post-cyclic – where phonological rules operate, as proposed by Booij & Rubach (1987).
Methodological Frameworks and Dimensions to Be Considered in Digital Health Technology Assessment: Scoping Review and Thematic Analysis
Authors: Segur-Ferrer Joan , Moltó-Puigmartí Carolina , Pastells-Peiró Roland , Vivanco-Hidalgo Rosa Maria
Published: February 2024

Background

Digital health technologies (dHTs) offer a unique opportunity to address some of the major challenges facing health care systems worldwide. However, the implementation of dHTs raises some concerns, such as the limited understanding of their real impact on health systems and people’s well-being or the potential risks derived from their use. In this context, health technology assessment (HTA) is 1 of the main tools that health systems can use to appraise evidence and determine the value of a given dHT. Nevertheless, due to the nature of dHTs, experts highlight the need to reconsider the frameworks used in traditional HTA.

Objective

This scoping review (ScR) aimed to identify the methodological frameworks used worldwide for digital health technology assessment (dHTA); determine what domains are being considered; and generate, through a thematic analysis, a proposal for a methodological framework based on the most frequently described domains in the literature.

Methods

The ScR was performed in accordance with the guidelines established in the PRISMA-ScR guidelines. We searched 7 databases for peer reviews and gray literature published between January 2011 and December 2021. The retrieved studies were screened using Rayyan in a single-blind manner by 2 independent authors, and data were extracted using ATLAS.ti software. The same software was used for thematic analysis.

Results

The systematic search retrieved 3061 studies (n=2238, 73.1%, unique), of which 26 (0.8%) studies were included. From these, we identified 102 methodological frameworks designed for dHTA. These frameworks revealed great heterogeneity between them due to their different structures, approaches, and items to be considered in dHTA. In addition, we identified different wording used to refer to similar concepts. Through thematic analysis, we reduced this heterogeneity. In the first phase of the analysis, 176 provisional codes related to different assessment items emerged. In the second phase, these codes were clustered into 86 descriptive themes, which, in turn, were grouped in the third phase into 61 analytical themes and organized through a vertical hierarchy of 3 levels: level 1 formed by 13 domains, level 2 formed by 38 dimensions, and level 3 formed by 11 subdimensions. From these 61 analytical themes, we developed a proposal for a methodological framework for dHTA.

Conclusions

There is a need to adapt the existing frameworks used for dHTA or create new ones to more comprehensively assess different kinds of dHTs. Through this ScR, we identified 26 studies including 102 methodological frameworks and tools for dHTA. The thematic analysis of those 26 studies led to the definition of 12 domains, 38 dimensions, and 11 subdimensions that should be considered in dHTA.

Authors: Mondal Arijit
Published: February 2024

With the global outbreak of the Covid-19 pandemic, there has been a heightened interest in pandemic literature and epidemic narratives, as the everyday lives of individuals undergo significant transformations in response to the arrival of such a pandemic, reflecting a growing curiosity about how literature explores and elucidates these challenging experiences. It is widely acknowledged that there has been no shortage of pandemic literature and related material in world literature, including Indian vernacular literature, available in both its original languages and translated forms, underscoring the richness and diversity of perspectives on pandemics across different literary traditions. What is particularly intriguing is that socially conscious and perceptive writers often use epidemics or pandemics as a lens through which to critically examine and delve into the intricate layers of India’s caste-based hierarchical social structure, offering a unique perspective to dissect and reflect upon the dynamics of this deeply entrenched societal framework. In this paper, an attempt has been made to examine Anantha Murthy’s Samskara: A Rite for a Dead Man as a pandemic narrative that brilliantly captures the vignettes of the reality of superstition-ridden society at times of crisis and emergency. The paper also endeavours to investigate how literature seeks to provide solace during moments of necessity and hardship by offering an insightful account of various events that occur during pandemics, illustrating how the portrayal of pandemics in literature often serves as a source of inspiration for humanity, highlighting the capacity of literature to offer guidance and motivation in challenging times.

Authors: Gagabo Sisay Yohannes , Chika Kulong Wechtuor , Kuse Kenenisa Abdisa , Bora Bereket Bekele
Published: February 2024

Ethiopia has a long and rich history of dairy farming, which was mostly carried out by small and marginal farmers who raised cattle, camels, goats, and sheep, among other species, for milk. Finding the Itang Special Woreda cow milk value chain is the study's main goal. In order to gather primary data, 204 smallholder dairy farmer households were randomly selected, and the market concentration ratio was calculated using 20 traders. Descriptive statistics, econometric models, and rank analysis were used to achieve the above specified goals. Out of all the participants in the milk value chain, producers, cafés, hotels, and dairy cooperatives had the largest gross marketing margins, accounting for 100% of the consumer price in channels I and II, 55% in channels III and V, and 25.5% in channels V. The number of children under five, the number of milking cows owned, the amount of money from non-dairy sources, the frequency of extension service contacts, the amount of milk produced each day, and the availability of market information were found to have an impact on smallholders' involvement in the milk market. Numerous obstacles also limited the amount of milk produced and marketed. The poll claims that general health issues, sickness, predators, and a lack of veterinary care are plaguing farmers. In order to address the issue of milk perishability, the researchers recommended the host community and organization to construct an agro milk processor, renovate the dairy cooperative in the study region, and restructure the current conventional marketing to lower the transaction and cost of milk marketing.

Horizontes de representación para las mujeres. Un análisis de la representación sustantiva en la LXIV Legislatura
Authors: Cortes Hernández Lic. Ana Karen
Published: February 2024

Las cuotas de género fueron políticas públicas que trazaron el camino para institucionalizar la representación paritaria de las mujeres. Se busca entender si contar con un Congreso paritario ha permitido que las diputadas transverzalicen la perspectiva de género y/o feminista en su ejercicio legislativo y, por ende, llegar a una representación sustantiva para las mujeres. Se lleva a cabo un ejercicio de representación descriptiva en las XLIV y XLV Legislaturas; de representación sustantiva (con una revisión, análisis y clasificación de iniciativas) en la LXIV Legislatura y un análisis sobre cómo estas iniciativas se convierten en políticas que promueven la igualdad sustantiva para las mujeres.

Creativity in mathematics is one of the abilities that students in solving a problem must master. With creativity, students can develop their ideas to produce various solutions. However, in reality, the ability to think creatively is still low. This is because teacher-centred learning does not provide opportunities for students to develop their ideas creatively. Therefore, this study aims to describe the emergence of indicators of students' creative thinking abilities in solving mathematical problems on reflection material using the Palembang songket context. This type of research is a qualitative descriptive research subject, namely 3 class IX students. The research was carried out in three stages, namely, the preparation stage, the implementation stage, and the data analysis stage. The data in this study were collected through written tests and interviews. A written test was conducted to measure students' creative thinking skills data reduction, data presentation, and conclusion will be analyzed in three stages. The study found that fluency, flexibility, and elaboration were the most commonly used indicators of students' creative thinking abilities. Meanwhile, for the authenticity indicator, only one subject melts the indicator.Keywords:  Student Creativity, Reflection Material, Context

A utilização de estruturas metálicas em projetos do cotidiano apresenta inúmeras vantagens, tais como, maior resistência mecânica e menor peso, além de garantir um alto padrão de qualidade em construções. Um exemplo de estrutura metálica que se pode citar são as treliças. Nesse modelo de estrutura os elementos pertencentes ao conjunto estão em um único plano e sua aplicabilidade se dá, principalmente, na construção de coberturas e pontes. Sendo assim, a realização de um dimensionamento adequado, o qual garanta a segurança e a resistência da estrutura, além de respeitar normas vigentes é imprescindível. Este trabalho tem por finalidade projetar e confeccionar um protótipo de treliça plana do tipo Pratt, comparando-se os resultados obtidos através de um ensaio experimental com o modelo analítico do software Ftool®, e o modelo numérico, via software SolidWorks®, obtendo-se as deformações desta estrutura ao ser submetida a esforços normais de tração e compressão, possibilitando determinar as seções onde os esforços atuantes são críticos. A treliça analisada apresentou uma tensão máxima de 3,12 MPa para uma carga máxima de 112 kgf, assim, estando abaixo do limite de escoamento do material utilizado para sua construção (205 MPa). Conclui-se também que os elementos estruturais submetidos a compressão não apresentaram instabilidade estrutural quanto a flambagem.

O município de Macapá, localizado na Amazônia Oriental, apresenta dados alarmantes quando se trata dos indicadores do saneamento básico, já que se encontra na última colocação no ranking entre os 100 maiores municípios do país, com 62,4% e 89,2% da população sem acesso à água tratada e coleta de esgoto, respectivamente. Desse modo, esse estudo tem por objetivo analisar a evolução dos serviços de saneamento, entre os anos de 2012 e 2021, identificando as perspectivas futuras para o município em virtude da concessão realizada. Desde julho de 2022, o saneamento de Macapá está passando por inúmeras reformas realizadas pela Concessionária de Saneamento do Amapá (CSA), tais como: melhoria da estrutura de captação de água bruta, da Estação de Tratamento de Água (ETA) e dos laboratórios de análises de qualidade de água; e recuperação da Estação de Tratamento de Esgoto (ETE). Portanto, há perspectivas de que o sistema de saneamento será aprimorado em termos de cobertura e eficiência. Nesse sentido, as projeções apontam para uma evolução no sistema de abastecimento de água e esgotamento sanitário, para 99% em um período de 11 anos, e 90% nos próximos 18 anos, respectivamente.

Published: February 2024

The essential oil of Corymbia citriodora (Hook.) has a wide application in industry, mainly due to the high concentration of citronellal present in the extracted oil, which gives the species an intense and pleasant odor. The present work aimed to evaluate the influence of the equipment used to extract the essential oil from C. citriodora leaves using steam distillation and the influence of this variation on the extraction efficiency of the compounds. Extractions were carried out for 1 h and 4 h, using two extraction systems, the traditional Clevenger apparatus and a Developed System. The type of system had no significant effect on the yield of extracted essential oil. However, both the type of system and the extraction time influenced the individual contents and extracted masses of some of the main components of the essential oil. This indicates the potential for developing a system in which operational parameters can be modulated, allowing the extraction and purification of essential oil components from C. citriodora leaves in a single step.
