Osteoblasts pattern endothelium and somatosensory axons during zebrafish caudal fin organogenesis
Authors: Bump Rosalind G. , Goo Camille E. A. , Horton Emma C. , Rasmussen Jeffrey P.
Published: February 2022

Skeletal elements frequently associate with vasculature and somatosensory nerves, which regulate bone development and homeostasis. However, the deep, internal location of bones in many vertebrates has limited in vivo exploration of the neurovascular-bone relationship. Here, we use the zebrafish caudal fin, an optically accessible organ formed of repeating bony ray skeletal units, to determine the cellular relationship between nerves, bones and endothelium. In adult zebrafish, we establish the presence of somatosensory axons running through the inside of the bony fin rays, juxtaposed with osteoblasts on the inner hemiray surface. During development we show that the caudal fin progresses through sequential stages of endothelial plexus formation, bony ray addition, ray innervation and endothelial remodeling. Surprisingly, the initial stages of fin morphogenesis proceed normally in animals lacking either fin endothelium or somatosensory nerves. Instead, we find that sp7+ osteoblasts are required for endothelial remodeling and somatosensory axon innervation in the developing fin. Overall, this study demonstrates that the proximal neurovascular-bone relationship in the adult caudal fin is established during fin organogenesis and suggests that ray-associated osteoblasts pattern axons and endothelium.
Endoplasmic reticulum–mitochondria signaling in neurons and neurodegenerative diseases

Published: February 2022

Recent advances have revealed common pathological changes in neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis with related frontotemporal dementia (ALS/FTD). Many of these changes can be linked to alterations in endoplasmic reticulum (ER)–mitochondria signaling, including dysregulation of Ca2+ signaling, autophagy, lipid metabolism, ATP production, axonal transport, ER stress responses and synaptic dysfunction. ER–mitochondria signaling involves specialized regions of ER, called mitochondria-associated membranes (MAMs). Owing to their role in neurodegenerative processes, MAMs have gained attention as they appear to be associated with all the major neurodegenerative diseases. Furthermore, their specific role within neuronal maintenance is being revealed as mutant genes linked to major neurodegenerative diseases have been associated with damage to these specialized contacts. Several studies have now demonstrated that these specialized contacts regulate neuronal health and synaptic transmission, and that MAMs are damaged in patients with neurodegenerative diseases. This Review will focus on the role of MAMs and ER–mitochondria signaling within neurons and how damage of the ER–mitochondria axis leads to a disruption of vital processes causing eventual neurodegeneration.

Published: February 2022

Background: While low sodium intake (<2.3g/day) is recommended for all, there is uncertainty about feasibility and net cardiovascular effects. In COSTICK, we evaluated the effects of a dietary counselling intervention (reduced sodium intake) on intermediate cardiorenal outcomes in patients with (STICK) and without (COSIP) mild/moderate kidney disease.

Methods: This is a protocol for two phase IIb randomised, two-group, parallel, open-label, controlled, single centre trials. Participants were aged >40 years with stable blood pressure, unchanged anti-hypertensive medications, willing to modify diet and provided written informed consent. Participants were excluded for abnormal sodium handling, heart failure, high dose diuretics, immunosuppression, pregnancy/lactation, postural hypotension, cognitive impairment, high or low body mass index (BMI) or inclusion in another trial. STICK participants had estimated glomerular filtration rate (eGFR) 30-60ml/min/1.73m2 and were excluded for acute kidney Injury, rapidly declining eGFR; known glomerular disease or current use of non-steroidal anti-inflammatory drugs. For COSIP, participants were excluded for known kidney or cardiovascular disease. Participants were randomized to usual care only (healthy eating) or an additional sodium lowering intervention (target <100mmol/day) through specific counseling (sodium use in foods, fresh over processed foods, sodium content of foods and eating outside of home). In STICK the primary outcome is change in 24-hour urinary creatinine clearance. In COSIP, the primary outcome is change in five biomarkers (renin, aldosterone, high sensitivity troponin T, pro-B-type natriuretic peptide and C-reactive protein). Our primary report (COSTICK), reports six biomarker outcome measures in the entire population at 2 years follow-up.

Discussion: These Phase II trials will explore uncertainty about low sodium intake and cardiovascular and kidney biomarkers, and help determine the feasibility of low sodium intake. Trial results will also provide preliminary information to guide a future definitive clinical trial, if indicated.

Trial registration: STICK: ClinicalTrials.gov NCT02738736 (04/04/2016); COSIP: ClinicalTrials.gov NCT02458248 (15/05/2016)
Prototyping Design of Low-Cost Bias-T Circuit Based-on Op-Amp for Visible Light Communication
Authors:   Program Studi Sistem Telekomunikasi, Universitas Pendidikan Indonesia, Bandung (40154), Indonesia, Fuada Syifaul
Published: February 2022

The visible light communication (VLC) exploits the LED as an antenna in which only works on “forward bias” conditions. Therefore, when the VLC has an input signal with minus voltage it will be clipped, and only the positive side is transmitted by LED. If the VLC has an analog signal input with a completely positive amplitude, the LED may exhibit flicker-effect when the input frequency is relatively low to medium. Therefore, the correct method for LED conditioning is by lumping the information signal in the DC area. The “Bias Tee” (Bias-T) is a commercial module that is most commonly applied for LED conditioning with analog input signal characteristics. Although the performance is powerful and significant for transmitting the high-frequency, the cost is relatively inexpensive. Therefore, this study proposes a low-cost Bias-T module for a low bit-rate VLC system. Instead of the Bias-T generally, that uses an inductor and capacitor, this module is built by Op-Amps circuit which consists of 1) buffer Op-Amp as DC input (VDC-OFFSET), 2) variable Pre-Amplifier as signal information input (VINF), 3) summing amplifier to combine these two signals (VINF + VDC-OFFSET) and 4) current amplifier for increasing the high-power LED with no-flicker (stable illumination). The designed Bias-T is built on a discrete component. The evaluations involved three approaches, given the input signal: 1) with a single carrier in sine form, 2) analog signal from digital signal processing (DSP) board, 3) audio signal generated from a personal computer. In summary, the Bias-T works as properly as expected.
VSE-TAKI AS A MARKER OF MONOLOGICAL DISCOURSE CONTRADICTION
Authors: Tashlykova Marina B. , Loshanina Maria N.
Published: February 2022

Background. The research was carried out within the project «Oral history of Irkutsk and technologies oral history in an interdisciplinary perspective». An analysis of the array of in-depth interviews obtained during the implementation of the project reveals a significant number of fragments reflecting the internal conflict of the speaker’s ideas about some fragment of the real world, which is in the center of his attention at a certain moment of speech. A current issue is to identify linguistic and discourse markers that objectify the presence of this conflict. One of these markers is vse-taki to which the article is devoted.

The purpose of the work is to clarify the idea of the status of this unit, its semantic, pragmatic and functional features, based on the understanding of the existing lexicographic tradition and the analysis of empirical material.

The material of the research is the data of traditional explanatory dictionaries and the Active dictionary of the Russian language, as well as examples of contextual use of vse-taki, extracted from the RNC. Methods and techniques of definitional, structural-semantic, contextual and corpus analysis are used.

The results of the research showed that vse-taki should be qualified as a particle which is used (a) as a marker of the opposition of the existing state of affairs to a hypothetical, but more standard one; (b) as a marker of the reason for the implementation of one of the two alternatives; (c) as a marker of the speaker’s emotional reaction to the coincidence of fragments of the mental and real world.

The field of practical implications of the results is theoretical semantics and discourse analysis (including in social research). The results can be used in semantics, pragmatics, discourse theory university courses.

The object of the research is to analyze sign languages which have been an essential aspect of communication throughout human history of the disabled. It aims to examine the main stages of development of sign languages.

The subject of the research is sign languages of the deaf and the hearing impaired.

The research methods include a theoretical analysis of the works of Russian and foreign linguists and the method of comparative analysis.

The results of the analysis of the main stages of sign languages let us come to the conclusion that the status of sign languages which have passed the historical gradual development responding to the needs of a developing society. The following aspects such as the verbal national language, linguistic schools, the culture of the people have a huge impact on the formation and development of any sign language. It should be noted that sign languages as well as verbal languages are related to each other. They are functionally complete (natural) languages with their own, sometimes rather complex internal mechanism.

Strengths-based Megacommunities and the Appreciative Inquiry’s Complete Convention: Creating Wholepower, Willpower and Waypower for Our World’s Earthshot Moment
Authors: Cooperrider David L. , Godwin Lindsey N.
Published: February 2022

Megacommunities are not communities of individuals, but communities of positive institutions and organizations. They are able to mobilize conscious and collective co-elevation by cultivating the wholepower, willpower, and waypower needed to escape the gravitational pull of our society’s too-often growing sense of despair and learned helplessness. In this article we illustrate the ‘how’ of building megacommunities such as the UN Global Compact and others through Appreciative Inquiry’s ‘complete convention’ – what we call convention 3.0.

BOXED IN. Challenges of Escaping the Inherited Spatial Realities of Apartheid from the Centre to The Periphery.
Authors: Ramatlo Tebogo
Published: February 2022

This paper interrogates the existing spatial realities of Johannesburg as it was shaped by colonialism and the challenges of providing an inclusive urbanism between the centre, the periphery and the in-between. Johannesburg is a major urban centre in South Africa, with increasing economic and spatial inequality. The inherited spatial realities are still evident today; these structural realities are restrictive, unsustainable, and disadvantage communities ecologically, economically and socially. The paper is premised on an understanding that economic inequality is related to spatial inequality. The author draws on the personal lived experiences of being born on the periphery and the limitations of escaping the legacies of colonial spatial planning including the challenges of living on fragmented urban morphology.The author looks at the typology of the segregated post-apartheid township and the negative elements of apartheids spatial planning, especially focused on the restrictions it has on housing, employment opportunities, transport and public space on the periphery in comparison to the centre and how the in-between spaces further perpetuate socio-economic disparity. The author attempts through research to understand the resilience adopted by the Soweto community to have a safe and welcoming place despite the persistence of structural restrictions. The intention is to address the fragmentation and segregation caused by the inherited spatial structures. The planning of colonial cities, especially Johannesburg was based on achieving maximum control. The urban morphology was many times based on policies that organised people through race, class, and ethnicity.Its spatial planning was defined by separating citizens into different racial groups and economic classes. The rich white people located in the suburbs in the centre and the poor black people located in townships at the periphery separated by wide natural and man-made buffers in-between. The urban morphology of Johannesburg will be studied with a comparison analysis with other African cities which have similar patterns of spatial fragmentation in urban form due to colonial powers. The aim is to observe, compare and propose a defragmentation process towards the transformation of Johannesburg
So Close Yet So Far: Divided Contexts on the Mexico-Guatemala Border.
Authors: Zapata Montalvo Luis Fernando
Published: February 2022

La frontera entre México y Guatemala es el resultado de la confluencia geopolítica de dos países con prioridades diferentes, generando diferentes formas de organización en la vida de sus habitantes y de las personas que transitan por esta zona. Este contexto ha creado condiciones de interacción sobre lo que cada país considera legal, ilegal y punible, dando lugar a varias interpretaciones de los fenómenos migratorios. Son contextos reales que adoptan el tránsito de personas. Situaciones que son posibles y dan sentido a la vida de muchas personas en contextos divididos. Este artículo presenta una visión general de dos lugares transfronterizos entre México y Guatemala que pretenden describir la zona fronteriza y la movilidad de las personas como un fenómeno social. ¿Qué motiva a las personas a moverse entre ambos países? y ¿cuáles son las relaciones y decisiones vinculadas a que alguien o algo pueda moverse y decida hacerlo? más aún cuando esta movilidad supone el cruce de una frontera delimitada políticamente, son algunas de las preguntas planteadas en este artículo. Para responder a estas preguntas, realicé un enfoque cualitativo, que pretende lograr una mejor comprensión de la dinámica de las personas que viven en estos lugares.
The communication of sexual diversity in social media:: TikTok and Trans Community.
Authors: Olivares-García Francisco J.
Published: February 2022

This paper analyzes the communication of sexual diversity in social networks, based on the analysis of ten accounts of influential Spanish speaking users, members of the trans community, on the TikTok platform. In addition to showing humor and dance videos, this network has also become a communication tool for all kinds of groups, including the LGTBI+ community and the trans community. The videos posted by users, in which they talk about issues related to the transition process are offered not only to people interested in the subject, but to all kinds of public, which causes an effect of normalization and visibility that is not found on other platforms, where this content is only consumed mainly by other trans people or people interested in the subject.

GENDER VIOLENCE PREVENTION AS LEADERSHIP EDUCATION: Feminist-Inspired Bystander Training for College Student Leaders
Authors: Eriksen Shelley J.
Published: February 2022

This exploratory study examined the leadership education potential of sexual assault prevention training via a prevention approach that expressly constructs bystander education as a leadership issue. Evaluation of the Mentors in Violence Prevention (MVP) program offers a practical application of a leadership education approach through a feminist lens, a framework recently advocated by Iverson, McKenzie, and Halman (2019) to better prepare student leaders for active engagement with the central social issues of their time. After undergoing one-day MVP leadership trainings, student leaders (n = 239) evidenced positive gains in such areas as leadership readiness in gender violence prevention, confidence as bystanders, and a willingness to help others. Results also suggest that participants’ prior knowledge, leadership background, and peer group membership shaped their engagement with the program. As a feminist method, MVP worked well for both women and men and across students’ varying racial/ethnic identities, but differences by peer group reveal areas in which additional research and intervention programming may be needed.

SUPPORT FOR ORGANIZATIONAL CHANGE AMONG EXTENSION EDUCATORS
Authors: Windon Suzanna , Stollar Mariah
Published: February 2022

This study sought to assess perceptions of support for organizational change and model the relationship between support for organizational change and leadership competencies among Extension educators. The knowledge gained through this work should expand current understandings regarding the nature, scope, and value of support for organizational change within the Extension educator role. We found that Extension educators mostly support organizational change. Our study also showed that leadership competencies predict a significant proportion of the total variation in overall support for organizational change. Extension leaders and leadership development practitioners should be aware that leadership education may increase receptivity to organizational change among educators.
THE PATH TO INCLUSION: A Literature Review of Attributes and Impacts of Inclusive Leaders
Authors: Fagan Helen Abdali Soosan , Wells Brooke , Guenther Samantha , Matkin Gina S.
Published: February 2022

The impending demographic shift in the United States (Vespa et al., 2020) will require leadership educators to reexamine the relationship between diversity and inclusive leadership. Our literature review revealed inclusive leadership has historically not been viewed with a diversity perspective. To better understand the link between diversity and inclusive leadership, we reviewed how leadership scholars, researchers, and authors have described the attributes and impacts of inclusive leaders. Through inductive coding, we identified seven attributes (i.e., characteristics and actions) of inclusive leaders. When these attributes are acted upon, inclusive leaders create various impacts on followers. These impacts are applied to Shore et al.’s (2011) inclusion framework. Both the attributes and impacts are presented to provide information and tools to better equip leadership educators with the knowledge to foster classroom inclusion in diverse classroom environments.
Heavy-Traffic Insensitive Bounds for Weighted Proportionally Fair Bandwidth Sharing Policies
Authors: Wang Weina , Maguluri Siva Theja , Srikant R. , Ying Lei
Published: February 2022

We consider a connection-level model proposed by Massoulié and Roberts for bandwidth sharing among file transfer flows in a communication network. We study weighted proportionally fair sharing policies and establish explicit-form bounds on the weighted sum of the expected numbers of flows on different routes in heavy traffic. The bounds are linear in the number of critically loaded links in the network, and they hold for a class of phase-type file-size distributions; that is, the bounds are heavy-traffic insensitive to the distributions in this class. Our approach is Lyapunov drift based, which is different from the widely used diffusion approximation approach. A key technique we develop is to construct a novel inner product in the state space, which then allows us to obtain a multiplicative type of state-space collapse in steady state. Furthermore, this state-space collapse result implies the interchange of limits as a byproduct for the diffusion approximation of the unweighted proportionally fair sharing policy under phase-type file-size distributions, demonstrating the heavy-traffic insensitivity of the stationary distribution.

MAMANA FANISSE, DE JOSÉ CRAVEIRINHA: ONDE A ESCRITA CARREGA DOR
Authors: Silva Avani Souza
Published: February 2022

Resumo: José Craveirinha foi um poeta e escritor dos mais engajados em Moçambique contra a colonização portuguesa. Foi também um dos primeiros poetas moçambicanos a assumir os valores da Negritude e da Moçambicanidade. Sua poética é inspirada no cotidiano de seu país, que ele toma como metonímia da África: identidade africana, memórias familiares e também a fome, o abandono, a miséria, o racismo, a falta de oportunidades, a doença e a morte. A infância é um tema importante na prosa do escritor, em que ele mostra a miséria e abandono a que as crianças estavam relegadas durante o colonialismo português. Para mostrar esse aspecto da obra de Craveirinha, analisaremos o conto “Mamana Fanisse”, do livro Hamina e outros contos, apontando diálogos intratextuais na obra que reforçam o tema. Com base na noção de identidade e resistência cultural concebidos por Stuart Hall (2006) focalizaremos os elementos identitários utilizados na obra pelo escritor que reforçam essas noções, como a música por exemplo.
A BICICLETA QUE TINHA BIGODES’ E A CARTA DO MENINO N
Authors: Santos Izabel Cristina da Rosa Gomes Dos
Published: February 2022

O presente texto propõe desvelar o lugar da infância a partir das crianças narradoras apresentadas pelo escritor angolano Ondjaki. O estudo propõe-se a um diálogo com a obra literária A Bicicleta Que Tinha Bigodes(2012) e a pluralidade da infância presente nas discussões de Larrosa (2004), Kohan (2010), Kramer (2009). Nesse sentido, ancorou-se em uma escolha metodológica a partir das contribuições das diferentes áreas do conhecimento e suas relações com a infância. Ressalta-se, também, as contribuições do pensamento africano acerca do cuidado de si e do outro, ou seja, uma ética da sensibilidade, constituída pelo equilíbrio das relações de existência, pois há seres coisas e há seres humanos que se harmonizam em convivência plena. Ainda por este estudo, evidenciou-se o que a literatura provoca-nos a pensar acerca das infâncias, da alteridade e da ancestralidade. A ideia central deste texto pauta-se em uma permeabilidade conceitual que possa ser aporte para pensar qual é o lugar da infância, a partir das imagens literárias da obra mencionada e do contexto angolano de resgate de afetos e defesa de um poder político pós-independência que se assentava como hostil e belicoso. Talvez também seja possível pensar que a importância da infância seja equivalente a um resgate da utopia, tal como a revolução foi a utopia da geração anterior aos anos 80. Essas escolhas, em busca de entrecruzar literatura e infância, permitiram um olhar ao que diz o Menino N, ou menino narrador, em narrativas de uma infância vivida em Angola, em um momento histórico marcado pela guerra civil e pela presença soviética e cubana em Angola. Importa dizer de um narrar a vida ainda em estado de infância.Palavras-chave: Infância. Menino N. Ondjaki.

O presente artigo analisa algumas representações da infância em narrativas literárias de Mia Couto, em diálogo com a História. Nessa tarefa, partimos de definições da infância elaboradas por estudiosos do assunto, como Ariès (1981), Foucault (1995), Heloiza Castro (2019), Betina Hillesheim e Neuza Guareschi (2007). Consideramos também tratados internacionais, ratificados por Moçambique, e estudos sobre a infância moçambicana, como os de Celestino e Pastore (2018), Pastore e Barros (2016). Além disso, tecemos alguns diálogos com a fortuna crítica à obra coutiana, que conta com nomes como os de Francisco Noa (2019), Moema Marques (2012) e Petar Petrov (2014), entre outros. Com isso, esperamos contribuir para uma mais ampla compreensão da situação das crianças representadas na narrativa literária do escritor moçambicano Mia Couto.

The present study aims to investigate the problem-solving skills of the students getting professional music training. For this study, the problem-solving inventory was administered to participants from two different universities in Turkey. Participants’ problem-solving skills were assessed in relation to the overall inventory and subscales, and the differences based on grade level, gender, and universities were examined using Statistical Package for the Social Sciences (SPSS). Results revealed that participants occasionally used their problem-solving skills, rarely felt confident in their problem-solving skills, and occasionally performed the behaviors in the subscales of approach-avoidance and personal control. The grade level differentiated music students’ problem-solving skills in the overall scale and approach-avoidance subscale. It is also found that there are no significant differences in students’ problem-solving skills based on gender. However, the participants’ universities led to significant differences in the approach-avoidance subscale. The results were discussed considering the literature, and the recommendations were suggested due to the results.

Corresponding to industry trends and changes in engineering education accreditation criteria, non-technical professional skills training is now seen as central to baccalaureate engineering education. Beyond simply developing good managers in the engineering fields, engineering educators have adopted a goal to prepare engineering students to be leaders who can provide vision to their organizations with strong ethical standards. This study investigated engineering undergraduate students’ leadership efficacy development associated with such professional skills as self-awareness, global competence, ethical awareness, creativity, and teamwork skills. Responding to an online survey, 247 engineering undergraduates who were enrolled in an engineering leadership course participated in this study. Results of this study indicated that there are positive associations among the five professional skills (e.g., self-awareness, ethical awareness, global competency, creativity, and teamwork skills), and engineering leadership self-efficacy for engineering undergraduate students. The five professional skills (self-awareness, ethical awareness, global competency, creativity, and teamwork skills) predicted 54% of the overall variance of engineering leadership self-efficacy.

Aims

The cemented Oxford unicompartmental knee arthroplasty (OUKA) features two variants: single and twin peg OUKA. The purpose of this study was to assess the stability of both variants in a worst-case scenario of bone defects and suboptimal cementation.

Methods

Single and twin pegs were implanted randomly allocated in 12 pairs of human fresh-frozen femora. We generated 5° bone defects at the posterior condyle. Relative movement was simulated using a servohydraulic pulser, and analyzed at 70°/115° knee flexion. Relative movement was surveyed at seven points of measurement on implant and bone, using an optic system.

Results

At the main fixation zone, the twin peg shows less relative movement at 70°/115°. At the transition zone, relative movements are smaller for the single peg for both angles. The single peg shows higher compression at 70° flexion, whereas the twin peg design shows higher compression at 115°. X-displacement is significantly higher for the single peg at 115°.

Conclusion

Bony defects should be avoided in OUKA. The twin peg shows high resilience against push-out force and should be preferred over the single peg. Cite this article: Bone Joint Res 2022;11(2):82–90.

Abstract. Indow L, Maturbongs RA, Prabawardani S, Hendri, Lyons G. 2021. Implementation of the remote indigenous community empowerment program on the sustainability of the local food crops in West Papua, Indonesia. Biodiversitas 22: 5247-5254. An ethnobotanical study of local food crops in the areas receiving the program of remote indigenous community empowerment (RIC) in the three ecosystem areas of Domberai, West Papua was conducted to assess the effect of the program on specific local food crops. This study used a descriptive method with qualitative and quantitative data components. Surveys and field observations were carried out at predetermined village locations, using a purposive sampling interview method with community representatives, tribal chiefs, and leaders in each indigenous community. Field data were analyzed quantitatively to find the value of the benefit index (BI) on food crops. Results of the study showed the highest BI values of carbohydrate-rich crops were banana (Musa sp.) which accounted for 98%, sweet potato (Ipomoea batatas) 98%, followed by taro (Colocasia esculenta) 94%, and cassava (Manihot esculenta) 90%. Vegetable crops with the highest BI values were gedi leaves (Abelmoschus manihot) 98%, papaya leaves (Carica papaya) 86%, followed by sweet potato leaves (Ipomoea batata) 56%, cassava leaves (Manihot esculenta) 56%, gnetum leaves (Gnetum gnemon) 55%, and pumpkin leaves (Cucurbita) 52%. The highest BI values in fruit crops were rambutan (Nephelium lappaceum) 72%, mango (Mangifera indica) 70%, and durian (Durio zibethinus) 59%. The shift from local food crops to rice has been observed in the villages of Sakumi and Yamboi which are relatively accessible for transportation, while the people of Watitindoi Village, which is located on a small island and is isolated, have been mostly relied on local food crops.

Karyotype analysis from four species of edible plants, namely one species from family Cannaceae (Canna indicaL.), one species including 2 variants from family Araceae (Colocasia esculenta(L.) Schott, green taro and black taro) and two species from family Apiaceae (Eryngium foetidum L. and Centella asiatica (L.) Urb.) in Maha Sarakham province, northeastern Thailand were determined from root tips. The results showed that the chromosome numbers and karyotype formulae were 2n= 28 = 14m + 10sm + 4st (2sat) with NF = 56 for green taro, 2n= 42 = 20m
+ 20sm + 2st (3sat) with NF = 84 for black taro, 2n = 18 = 18sm with NF = 36 for Centella asiatica (L.) Urb., 2n = 16 = 2m +14 sm with NF = 32 for Eryngium foetidum L., 2n= 27 = 2m
+ 25sm with NF = 54 for Canna indica L. Both taros had differences in the chromosome numbers and karyotype formulae. The chromosomes of both taros were the asymmetrical karyotype. While, the chromosome structure of both taros, including the number of metacentric, submetacentric and subtelocentric as well as the position of satellite-chromosomes, were found to be different, which indicated inter-and intra-specific variations in this species. Therefore, the chromosome number, karyotype formula, chromosome structure, position of satellite-chromosomes and idiogram can be used for classification of both taros in this study. Moreover, idiograms of both taros were reported for the first time. The karyotype, NF,  RL, CI and
ideogram of Centella asiatica(L.) Urb., Eryngium foetidum L. and Canna indica L. were reported for the first time.

Abstract. Budhathoki N, Dhakal S, Dyola U. 2021. Diversity of hoverflies (Diptera: Syrphidae) in Nagarjun, Shivapuri Nagarjun National Park, Nepal. Biodiversitas 22: 5382-5388. Hoverflies are recognized as potential pollinators of a wide range of wild plants. This study explored the abundance and diversity of hoverflies over three different seasons from October 2018 to April 2019 in two different study sites, i.e. forest and grassland at Nagarjun of Shivapuri Nagarjun National Park, Nepal. Each site of the study area was further divided into five sampling transect stations. Hoverflies were collected from each station by using two methods as pan trap sampling and transect sweeping sampling. Overall, a total of 373 specimens representing 13 species under nine genera of two subfamilies (Syrphinae and Eristalinae) were recorded. The abundance and diversity of hoverflies varied seasonally, the maximum number of individuals and diversity were recorded from the spring season, whereas the minimum number of individuals and diversity were found in the winter season. In addition, forest habitat consists of the highest abundance and diversity of hoverflies, whereas grassland consists of the lowest abundance and diversity. The analysis done by using generalized linear modeling (GLM) revealed climatic parameters such as temperature and humidity had a varying effect on the abundance of hoverflies. However, both these parameters had not any significant influence on the number of hoverfly species.

Abstract. Hidayati YA, Nurachma S, Badruzzaman DZ, Marlina ET, Harlia E. 2021. Utilization of sheep dung and rice straw with indigenous microbial agent to optimize vermicompost production and quality. Biodiversitas 22: 5445-5451. Sheep dung is a useful by product that can be potentially processed into more useful products with minimal pollution. Vermicomposting is a waste processing method that produces Solid Organic Fertilizer and worm biomass as the raw materials for drugs and cosmetics. This research aimed to utilize the role of indigenous fungi and bacteria to determine the influence of C/N ratio from sheep dung and rice straw mixture on vermicompost quality (N, P, K, Ca, Mg). This experimental research was conducted in a Completely Randomized Design with three treatments (T1: C/N ratio of 25; T2: C/N ratio 30; T3: C/N ratio 35) and six replicates for each treatment. Data so obtained were analyzed with ANOVA and Duncan's Multiple Range Test. The results showed that C/N ratio had a noticeable influence on vermicompost quality. C/N ratio 30 produced the highest vermicompost quality (N: 1.11 ± 023381%; P: 0.56 ± 0.010328 %; K: 0.51 ± 0.021369 %; Ca: 0.33 ± 0.0248 %; Mg: 0.14 ± 0.0228%).
