Authors: Thomas Paul , Onyango Daniel Oduor
Published: March 2022

Administrative challenges can disrupt effective implementation of curriculum in secondary schools. Literature review shows that many administrative challenges hinder the implementation of curriculum in secondary schools. In order to implement the curriculum effectively, school administrators need to provide support to teachers since they are crucial to ensuring that curriculum is delivered consistently, effectively, and efficaciously to enhance learners’ academic achievement and growth. This study sought to examine the effect of administrative challenges on curriculum implementation in public secondary schools in Nyamagana District – Mwanza City, Tanzania. The study adopted a convergent parallel design under a mixed method research approach and a sample size of 172 respondents. Data were collected using questionnaires and interview guide. Validity and reliability of the instruments were tested and were reliable to be given to the respondents for data collection. The findings of this study revealed that the school administrators face many challenges which make the curriculum not to be implemented effectively. The challenges which were mentioned include: lack of fiscal infrastructure, lack of guidelines for the implementation of the curriculum, insufficient funds, overcrowded classrooms, heavy workloads, teachers’ lack of commitment, complexity of managing curriculum, and school heads’ inability to supervise curriculum delivery. It is recommended that government should provide more funds whenever it rolls out an education innovation so as to enable the schools to effectively implement the innovation. There is also need to conduct seminars and workshops for school administrators to enable them to effectively implement curriculum innovations in secondary schools

PKBM as non-formal education provider in the form of equality education and life skills cannot stand alone to carry out its duties and roles. Therefore PKBM builds partnership networks with other parties so that roles and functions can be achieved, given the limited resources owned by PKBM units. The purpose of this study is to describe how the understanding of PKBM unit managers in building partnership networks. To answer the research objectives in general, the researcher explores information regarding the meaning of partnership networks for PKBM unit managers, characteristics of partnership networks, and factors that become obstacles in building partnership networks.This study uses a qualitative descriptive research method, involving 15 PKBM unit managers from several districts in Jambi Province, namely Batanghari, Merangin and Muaro Bungo. Data collected through observation, interviews, and documents were analyzed by following the steps of data analysis in qualitative research. The data that has been analyzed is tested for its validity in theory, field sources, and other sources.This study found that the understanding of building a partnership network for PKBM unit managers was limited to a practical understanding so that the available service programs could run according to plan with the limited resources of the PKBM unit. Therefore, this needs to be addressed by providing direct experience to PKBM unit managers through visits to other PKBM units that serve as references and providing training regarding PKBM management. The results of this study can be used for the development of community-based educational organizations.

Authors: Wang Ding , Liu Yawei
Published: March 2022

We have examined the effects of celastrol on the proliferation, migration, and apoptosis of colon cancer HT29 cells and miR-133b as a possible mechanism of action. The HT-29 cells were incubated with celastrol at different concentrations (0, 2, 4 μmol/L) for 24 h. Cell counting kit-8, scratch wound, and flow cytometry assays were used to evaluate the effects of celastrol on the HT29 cells’ proliferation, migration, and apoptosis. The content of the miR-133b in the HT29 cells and human normal colorectal mucosa fetal human cells was measured by quantitative real-time polymerase chain reaction. After treatment with different concentrations of celastrol, the proliferation and migration of the HT29 cells were both significantly inhibited in a dose-dependent manner (P < 0.05). Additionally, flow cytometry assay showed that celastrol induced the apoptosis of the HT29 cells in a dose-dependent manner. The miR-133b in the HT-29 cells was significantly lower than that in the fetal human cells. After treatment with celastrol, the miR-133b in the HT-29 cells was 3.78 times (2 μmol/L celastrol) and 4.59 times (4μmol/L celastrol) the content of untreated cells. Celastrol significantly inhibited the proliferation and migration, and promoted apoptosis of the colon cancer cells, which may be mediated by upregulation of the miR-133b. The expression of the miR-133b in the colon cancer cells was significantly inhibited.

Gender and COVID-19 global research agenda: priorities and recommendations
Authors: IIGH UNU , School of Public Health University of the Western Cape
Published: March 2022

Calls for greater recognition of and attention to the influence of sex and gender on health have been longstanding, and the need for this has only been amplified by the COVID-19 pandemic. Apart from the direct effects of biological sex and socially-constructed gender differences on COVID-19 morbidity and mortality – with higher rates of severe disease and deaths among men, pandemic responses have also amplified existing gender inequalities, with women bearing the heaviest burden of the indirect health and socio-economic consequences. The interactions between sex, gender and COVID-19 are complex and evolving, and further shaped and influenced by context and the intersecting influence of other social determinants and/or identities (such as race, ethnicity, LGBTQIA or migrant status, etc.), which have exacerbated the devastating health impacts for specific women, men and gender-diverse people. Recognising both the urgency of integrating sex and gender into COVID-19 research, and the roadblocks in the way of achieving this, the United Nations University International Institute for Global Health (UNU-IIGH) and the School of Public Health at the University of the Western Cape co- convened a collaborative gender and COVID-19 research agenda-setting exercise.

Development of information and communication technology changed mail delivery services in various parts of the world in the twenty centuries. In Java, the increase in postal services as Dutch East Indies government infrastructure) grew along with the construction of the Postweg line (postal road) in 1809–1811. The road networks pass through Jakarta – Semarang, Surabaya, and another small-town facility and now the postal networks became a heritage. The networks of post building in Semarang are unique compared to other big cities in Java. The Dutch East Indies government anticipated the geography of Semarang when they developed the expansion of the town to the south and utilized it by postal services. The government has issued a cultural heritage regulation for buildings and areas, but has not touched the conservation network of heritage. Based on that problem, this paper aimed to reveal Semarang city pattern used post office and infrastructure as a tool for analysing city morphology and suggested to conserve the heritage network. The method used was urban design with the historical approach, the post office location, settlements, road networks, and geographic conditions. The research findings showed that the postal infrastructure formed the sustainability of Semarang city from local-Dutch Indies rule in triangle form. The city’s geographical factor also influenced the city’s layout. The local and colonial city character in this triangle area is still preserved, although some minor changes in the area postweg road. The sustainability city layout from the era of local government – the Dutch East Indies in Semarang by making the city centre of the local government (in the top of the triangle) as the centre of urban design should be input on the heritage regulation as areas conservation.

A 26-year-old female presented recurrent painful, carbuncles at both axillae for 10 years. It caused offensive odor and scar. Tissue diagnosis was chronic hidradenitis suppurativa. She was treated using antibiotics followed by multiple excisions with drainage but showed no improvement. Isotretinoin provided no benefit. She was socially isolated and experienced lower quality of life. Consequently, she was sent for radiation therapy. Computed tomography simulation was performed revealing an ulcer with deep chronic pus tracts at her axilla. Three-dimensional conformal radiation therapy was provided with 6 MV photon (7.5 Gy in 3 fractions) covering all ulcers and pus tracts. On the last day of radiation therapy, carbuncles and wounds at the left axilla exhibited much improvement without pus. Three months follow-up showed much improvement of the lesions. The skin was smoother without pus or odor. Radiation therapy was confirmed one treatment option for chronic hidradenitis suppurativa.

Recently the understanding of complex biological systems has been increased considering the important interplay among different scholars coming from different applied sciences such as mathematics, physics and information sciences. As known, the modeling of a complex system requires the analysis of the different interactions occurring among the different components of the system. Moreover, the analysis of a complex system can be performed at different scales; usually the microscopic, the mesoscopic and the macroscopic scales are the most representation scales. However, a multiscale approach is required. A unified approach that takes into account the different phenomena occurring at each observation scale is the desire of this century. This editorial article deals with the topic of this special issue, which is devoted to the new developments in the multiscale modeling of complex biological systems with special attention to the interplay between different scholars.
Particle paths in equatorial flows
Authors: Lyons Tony
Published: March 2022

We investigate particle trajectories in equatorial flows with geophysical corrections caused by the earth's rotation. Particle trajectories in the flows are constructed using pairs of analytic functions defined over the labelling space used in the Lagrangian formalism. Several classes of flow are investigated, and the physical regime in which each is valid is determined using the pressure distribution function of the flow, while the vorticity distribution of each flow is also calculated and found to be effected by earth's rotation.
Les entrepôts de céréales en Espagne à l’époque moderne : contrôle public et marché préindustriel
Authors: Ubaldo Bernardos Sanz José , Antonio Mateos Royo José
Published: March 2022

L’évolution des greniers publics en Espagne à l’époque moderne est étudiée en tant que réponse institutionnelle aux aléas de la production agricole, à l’inégale distribution des excédents, principalement contrôlés par les seigneurs et l’Église, et à la fragile intégration des marchés. Dès la fin du Moyen Âge, les municipalités ont bâti des magasins publics (alhóndigas, pósitos) pour éviter les pénuries lors des périodes de crise. La croissance urbaine et les crises agricoles ont favorisé l’expansion de ces pósitos, mais les oscillations des prix ont fait augmenter les dépenses liées aux achats et, par conséquent, l’endettement municipal entre fin du XVIe siècle et 1630. Des entrepôts de charité (pósitos píos), pour les réserves de grains destinées à soutenir les paysans, se multiplient avec la crise du XVIIe siècle. L’intervention des Bourbons au XVIIIe siècle a cherché à améliorer la gestion des pósitos. Mais les résultats demeurent limités à cause des difficultés financières et de la crise finale du système d’Ancien Régime.

Published: March 2022

Out of the perovskite material used in Perovskite Solar Cells, methylammonium lead triiodide (MAPbI3) is the most studied, proving to yield a device with high power conversion efficiency. However, this perovskite material has a high tendency to degrade, especially when exposed to high humidity and ambient atmosphere. The degradation issue has led to its poor morphology, which eventually affects the device's power conversion efficiency based on this perovskite material. Therefore, this study aims to enhance the morphological property of the perovskite thin film by incorporating sulfonated reduced graphene oxide (srGO) as a dopant. The reduced graphene oxide is synthesized through modified Hummer's method and further sulfonated before being incorporated into the perovskite thin film deposited under relative humidity above 80% in ambient conditions. The srGO has successfully assisted the nucleation growth of MAPbI3 with the increment of grain size is approaching micron-sized. In this work, the optimized weight percentage of srGO in methylammonium iodide (MAI) precursor is found to be 20% resulting in grain size in the diameter range of 300 to 1000 nm. Hence, this perovskite doped srGO would be incorporated as the active layer for further application, especially in inverted planar perovskite solar cells.

Published: March 2022

Zinc oxide-titanium dioxide (ZnO-TiO2) have been successfully synthesized by hydrothermal method. ZnO-TiO2 nanocomposite were prepared at different molar ratio 100:0, 100:0, 30:70, 50:50 and 70:30. The objective of this research is to determine the effect of molar ratios on the structural and optical properties of ZnO-TiO2 nanocomposite. The samples were analyzed using X-ray diffraction (XRD) analysis, Field-emission scanning electron microscopy (FESEM) and UV-Vis spectroscopy. Based on the XRD results, it is revealed that ZnO-TiO2 nanocomposite consists of hexagonal wurtzite structure of ZnO and mixed of anatase/ rutile phase of TiO2. FESEM images showed ZnO in rod-like structure while TiO2 is formed in nanoparticle. ZnO-TiO2 composite is formed combination of rod-like and nanoparticles. UV-Vis spectra showed that all samples exhibited good absorption towards UV region. The calculated energy band gaps of ZnO-TiO2 composite are 2.92 eV which is slightly smaller compared to bulk ZnO and TiO2. The tuning energy band gaps of ZnO-TiO2 composite samples is a good indicator for use in catalytic activities.

Global energy consumption is increasingly becoming high due to industrial activity and advances both in developed and developing countries. Fossil fuels such as coal, natural gas, and oil are used to meet the energy demands all over the world. However, there is a concern about depletion of these resources and rise in greenhouse gas such as carbon dioxide emissions. Therefore, some alternative ways are needed to satisfy the energy demand and decrease the greenhouse emissions. Renewable energy, such as solar energy, wind energy, hydropower, and so on, is a promising source to satisfy the future energy requirements. As to solar cells, there is no need to concern about energy source because it uses solar rays, and it never emits CO2 when generating electricity.
Mechanical Properties of Pervious Concrete Containing East Borneo Local Aggregate
Authors: Pranoto Yudi , Hashim Nor Fazilah , Tumingan
Published: March 2022

This article identifies the potential of East Borneo local aggregates as a material in producing pervious concrete. East Borneo has to import material from another island (Palu / Central Sulawesi), which ends up with a high price in the concrete unit. In addition, high population growth, continual urbanization, rapid infrastructure development have reduced the infiltration area. This problem increases surface runoff, which can involve flooding. Research on the potential of local aggregates for porous concrete materials needs to be carried to reduce this problem. In this study, several coarse aggregates in East Borneo were used: Senoni, Cermin, Suryanata, and Muara Asa aggregates. This material is compared with Palu aggregate, which currently use in East Borneo. The tests such as compressive strength, split tensile strength, and flexural strength were carried out. Results of this research show that the concrete performance varies widely amongst the different aggregates. The compressive strength, flexural strength, and split tensile strength values range from 9.06 MPa to 21.97 MPa, 1.99 MPa to 3.98 MPa, and 1.38 MPa to 2.95 MPa respectively. Overall, Senoni aggregate is found as the best quality compared to other local aggregates. This research provides an overview of East Borneo local materials as infrastructure development to reduce dependence on Palu materials.

Authors: Youventharan Duraisamy , Jeevithan K.M. , Rokiah Othman , Mohd Arif Sulaiman
Published: March 2022

Recently, the incorporation of various waste materials into the ballast is studied in terms of physical and mechanical behavior. However, the inclusion of concrete debris (CD) and bottom ash (BA) waste, which are enlisted as the inventory materials for railway ballast have not been thoroughly examined. Hence, this paper investigates the improvement in damage resistance of waste incorporated conventional ballast (CB) under impact and crushing force using impact hammer and crushing machine. The initial and final particle size distribution (PSD) were obtained to analyze the damages through the Hardin‘s breakage index and fouling index. The results show that the resistance against crushing and impact force is better when the composition is in the ratio of 1:1 of conventional ballast (CB) and concrete debris (CD). Under crushing load, mixture with 50% of CD recorded breakage index with 4% deviation compared to using 100% of CB. However, integrating with 40% of CD and 10% of BA proved that the values are 2.14% lower than the ACV limit and 9.09% higher than the AIV limit set by British Standard. Although the impact and crushing index of 100% CB aggregates are below the allowable limit, mixing the CD and BA also records results which is only slightly different than the threshold limit. This is due to the cushioning effect caused by the waste acting as the buffering material that reduces the time of impact, which saves the angular materials from wearing off. This will reduce the ballast maintenance intervals that indirectly reduce the service cost and promotes sustainable construction. Based on the results from this study, further experiments are recommended to be carried out to relate and understand which waste material plays a major role in damage reduction or causing higher maitenance cost.

Integration of low bandgap antimonide based nanowires on Si substrate has been attracting huge attention for opto-electronic applications. In this work we demonstrated InAs/InSb and InAs/GaSb heterostructure nanowires on Si substrate by metal organic chemical vapor deposition. We grew high quality axial InSb heterostructure segment on InAs stem by self-catalyzed growth technique, which paves a way to tune the crystal structure of InSb. In case of InAs-GaSb core-shell architecture, GaSb crystal quality highly depends on InAs core. We successfully demonstrated basic electrical characteristics of InAs-GaSb core-shell nanowire which exhibits negative differential resistance at 0.8 V and peak-to-valley current ratio of 3.84.
Suprahyoid pharyngotomy – a rare, but a simple approach in head and neck surgery
Authors: Raghavendra P. , Fida Harish A. T. , Manohar S. R.
Published: March 2022

The surgical transcervical approach creates a corridor to oropharynx and hypopharynx, which provides excellent exposure for removal of different lesions at these sites. The suprahyoid pharyngotomy technique can be used in situations similar to the lateral pharyngotomy, like the management of benign and malignant tumors of the base of the tongue, hypopharynx, and posterior pharyngeal wall, and excision of lingual thyroid.
Here, we have discussed in detail about two patients for which this suprahyoid pharyngotomy approach was used – one, for a case of laryngeal schwannoma and another, for a case of lingual thyroglossal duct cyst. We have also reviewed many articles related to suprahyhoid pharyngotomy and came across 36 cases for which this approach was successfully used.

Instrumental swallowing assessment in children

Children can present with a wide range of swallowing impairments. This may affect from neonates, infants,toddlers, young children to early teens. The most serious outcome of a severe swallowing impairment is gross aspiration leading to violation of airway and its consequences such as recurrent aspiration pneumonias, sepsis, poor weight gain, failure to thrive and long term developmentalsequel.
Assessment of swallowing is done in children using perceptual clinical swallowing assessment by a speech and language therapist. This isa subjective assessment and may not clearly identify the defective phase of swallowing and may miss silent aspiration.
Instrumental swallowing assessment is a method to identify swallowing impairment by objective evaluation of the entire swallowing process. This would identify the phase and quantify the severity of the impairment. It is mainly done in two ways. i.e. the Functional Endoscopic Evaluation of swallowing (FEES) and Video Fluoroscopic Swallow Study (VFSS).
Both are valuable methods as they separately  assess different phases of swallowing. The results are invaluable in further treatment of these children to overcome or mitigate their impairment. FEES involves inserting a fibro-optic pediatric laryngoscope in the child’s pharynx via the nose and simultaneous observation of swallowing mechanism while feeding orally. VFSS involves fluoroscopic viewing of the swallowing process while giving food mixed with a radio opaque substance. VFSS  is further helpful in intra proceduralpositional maneuversand change in food consistencies to overcome the given impairment.
Thyme: A natural preservative for seafood
Authors: Yousefi Saman
Published: March 2022

Nowadays, food preservation for a long time without any change in quality is a global issue. Currently, 25 categories of food additives have been defined. These compounds are used to extend the shelf life of foods by protecting them against microorganisms as well as chemical reactions. Medicinal plants, having proven antimicrobial and antioxidant properties are suitable candidates for this purpose. Among them, thyme with a wide range of bioactive compounds has been extensively studied. This plant belongs to the family Lamiaceae and has a particular situation in traditional medicine. Nowadays, thyme and its derivate present a wide range of functional possibilities in the pharmacy and food industry. This article discusses thyme’s application as a food preservative in the seafood industry.

Making Space for Women’s Sexual Selves in Olive Schreiner’s From Man to Man
Authors: Nivesjö Sanja
Published: March 2022

In this article I argue that Olive Schreiner’s novel From Man to Man or Perhaps Only– (1926) explores the female subject’s relationship to sexuality in late nineteenth-century colonial South Africa in spatial terms. Reading the novel through Sara Ahmed’s (2006) idea of “queer phenomenology” and the concepts of “bodily horizon,” “extension,” and “orientation,” I claim that it is in the interaction of body and space that the potential lies for both oppression and resistance in relation to sexual and racial norms in the novel. The analysis focuses on how the main characters, Rebekah and Bertie, respond to restrictive sociosexual norms through their orientation in space. The article further considers how Rebekah and Bertie attempt to manage their troubled relation to colonial domesticity, and ultimately transform it, through their relationships with the servants Dorcas and Clartje and with Rebekah's adopted daughter Sartje; the former of which are ultimately imbued with notions of sexualised invasion. This article reveals how the spatial and embodied practices of the main characters are essential in negotiating their sexual positions in late nineteenth-century South African society.

Beyond Exception and Supremacy: Adwa in the Black Radical Imaginary
Authors: Michael Girma Kebede
Published: March 2022

Stories of Adwa have anchored multiple forms of exceptionalism that underpin some Ethiopians’ sense of superiority over others of African descent. This narrative mode goes hand-in-hand with certain toxic, solidarity destroying tendencies of some diasporic Ethiopians. Following the methodology of Tizita, innovated in Centime Elleni Zeleke’s Ethiopia in Theory, I analyse two such tendencies, social distancing and victim-blaming, in some depth. These forms of enacted exceptionalism weaken social movements like Black Lives Matter. This article offers a way out by thinking of Adwa as part of the black radical imaginary, a concept I develop drawing on the thinking of Cedric Robinson and Robin DG Kelley, and recent work by political theorists Paula Diehl and Craig Browne. The Battle of Adwa was one episode in a centuries-long process of resistance to racial capitalist patriarchy, a world system that still persists in many ways. Adwa must also be re-narrated if it is to be a viable source of solidarity among Ethiopians and within Ethiopia. Re-narrating Adwa with an eye toward non-Amhara and non-Tigre, and toward the anonymous, contributors to collective self-defense, is one way to tell a story geared toward an egalitarian politics focused on redressing historic wrongs. Gigi comes close to such a reading in her song Adwa.
Performing Guzo Adwa: Power, Politics and Contestations
Authors: Fana Gebresenbet  , Yonas Ashine
Published: March 2022

This paper documents a history and politics of memory project called Guzo Adwa. It highlights how, over the last eight years, Guzo Adwa emerged as a popular, performative commemoration of the battle of Adwa. Organised spontaneously by ambitious young men, who are passionate about history and adventure, culture and national politics, art and memory, Guzo Adwa emerged as a political performative, poetic and symbolic pilgrimage of the victory of Adwa. In its multiplicity, Guzo Adwa, which could be roughly interpreted as ‘Journey Adwa’, added to the already contested memory landscape pertaining to Adwa. The particularity of the project is that it has been organised neither as a mode of rule nor as an instrument of resistance. Moreover, the paper highlights how even this annual ritualized journey, as the memory project, embraced official and marginal political narratives, serving as a stage where varied economic interests and political issues surrounding national history were transpired. The paper is based on both primary and secondary sources. A total of ten formal interviews were conducted with key informants participating in Guzo Adwa in addition to informal discussions with others who have played some role in in the event , and other related memory projects. Newspaper archival research was conducted considering Addis Zemen reporting of Adwa commemoration as an ethnographic site. An attempt is made to attend events organised by the Guzo Adwa, especially the farewell ceremony of the eighth journey to Adwa. Finally, we try to locate the particular history of this memory project into national politics of memory and theoretical and conceptual debates in memory studies.

Authors: Bikoroti J.B. , Jahn A. , Muneza S. , Nyundo M. , Gashegu J.K. , Buteera A.M.
Published: March 2022

Background: A sacral parasitic twin is a variant of conjoined twins in which one twin is incomplete.

Case: A female newborn was delivered by cesarean section. Reported inconclusive obstetrical ultrasonography at the first trimester where the pregnancy was initially diagnosed dizygotic and in the second and third trimester was monozygotic. The neonate was born with a mass in the sacrococcygeal region, which was excised 24 days after birth. The mass contained the scalp, skull, cervical spine bone, and brain, which were confirmed as parasitic twins. The post-operative and follow up periods were uneventful.

Conclusion: Sacral parasitic rachipagus is a rare phenomenon; experienced antenatal ultrasonography may assist in the early diagnosis and excision is the treatment.
