Peran Realistic Mathematics Education (RME) Terhadap Miskonsepsi Siswa pada Materi Aturan Cosinus
Authors: Sukri Sukri , Usdiyana Dian , Pertiwi Destria Pitaloka
Published: October 2023

Realistic Mathematics Education (RME) dikembangkan dengan gagasan bahwa pembelajaran matematika yang pada umumnya berbentuk abstrak, baiknya dimulai dengan situasi yang realistis. Aturan cosinus pada materi trigonometri merupakan satu diantara sub materi yang abstrak sehingga siswa sulit untuk membentuk alur pikirnya yang mengakibatkan terjadinya rentetan kesalahan siswa dalam memahami konsep tersebut. Namun trigonometri juga memiliki kedekatan pada lingkungan sekitar siswa, sehingga dalam pembelajarannya dapat direpresentasikan lebih realistik. Penelitian ini memiliki tujuan untuk mengetahui peran dari RME terhadap miskonsepsi siswa MAN Tolitoli pada materi aturan cosinus. Penelitian ini menggunakan metode penelitian one-group pretest-posttest design dengan sampel penelitiannya adalah siswa kelas X MIA 1 yang berjumlah 33 siswa. Teknik pengumpulan datanya berupa tes yaitu pretest dan posttest. Pada hasil penelitian terungkap informasi bahwa sebelum diterapkannya pendekatan RME pada materi aturan cosinus, miskonsepsi siswa pada pretest untuk masing-masing jenis yakni klasifikasional, korelasional dan teoritikal secara berurut adalah 19.19%, 35.35% dan 23.23%. Kemudian setelah pembelajaran dengan RME dilakukan posttest dan diperoleh persentasi untuk masing-masing miskonsepsi klasifikasional, korelasional dan teoritikal secara berurut adalah 7.58%, 26.26% dan 15.15%. Hal ini terjadi penurunan persentasi untuk masing-masing miskonsepsi klasifikasional, korelasional dan teoritikal secara berurut sebesar 11,61%, 9,09%, dan 8,08%. Jadi, dapat disimpulkan bahwa RME efektif dalam mengatasi miskonsepsi siswa pada materi aturan cosinus.

Published: October 2023

Pendidikan berperan penting dalam membangun sumber daya manusia yang unggul dan berdaya saing. Namun, adanya pandemi COVID-19 telah menyebabkan hilangnya pembelajaran (learning loss) di kalangan peserta didik dan tenaga pendidik sehingga perlu dilakukan berbagai upaya pemulihan terkait hal tersebut. Selain itu, upaya pemulihan juga dilakukan untuk mendukung terlaksananya pendidikan berkualitas yang menjadi target dalam Sustainable Development Goals (SDGs) poin ke-empat. Namun, upaya tersebut juga perlu memperhatikan tingkat kualitas pendidikan di Indonesia yang berbeda-beda di setiap provinsinya. Oleh karena itu, diperlukan suatu pengelompokan atau klasterisasi provinsi di Indonesia berdasarkan indikator kualitas pendidikan untuk mempermudah pemerintah dalam upaya pemerataan kualitas pendidikan. Salah satu algoritma pengelompokan yang dapat digunakan adalah Fuzzy C-Means. Fuzzy C-Means merupakan suatu teknik pengelompokan data dimana keberadaan tiap titik data dalam suatu kelompok ditentukan oleh derajat keanggotaan. Data yang digunakan berasal dari publikasi Statistik Pendidikan 2022 oleh Badan Pusat Statistik. Adapun objek yang digunakan adalah 34 provinsi di Indonesia dengan 24 variabel yang merepresentasikan indikator kualitas pendidikan. Pada penelitian ini, dilakukan pengelompokan dengan skenario sebanyak 2 sampai dengan 5 cluster dan diperoleh cluster yang optimal yaitu 2 cluster. Validasi cluster optimal ini menggunakan indeks validitas yaitu PC, PE, dan MPC. Berdasarkan hasil penelitian, cluster pertama terdapat 12 provinsi yang dapat digolongkan sebagai kelompok provinsi dengan kualitas pendidikan rendah, sementara cluster kedua terdapat 22 provinsi yang dapat digolongkan sebagai kelompok provinsi dengan kualitas pendidikan tinggi.

Authors: Maes Iris , Mertens Lieze , Poppe Louise , Vetrovsky Tomas , Crombez Geert , De Backere Femke , Brondeel Ruben , Van Dyck Delfien
Published: October 2023

Background

Despite the availability of physical activity (PA) interventions, many older adults are still not active enough. This might be partially explained by the often-limited effects of PA interventions. In general, health behavior change interventions often do not focus on contextual and time-varying determinants, which may limit their effectiveness. However, before the dynamic tailoring of interventions can be developed, one should know which time-dependent determinants are associated with PA and how strong these associations are.

Objective

The aim of this study was to examine within-person associations between multiple determinants of the capability, opportunity, motivation, and behavior framework assessed using Ecological Momentary Assessment (EMA) and accelerometer-assessed light PA, moderate to vigorous PA, and total PA performed at 15, 30, 60, and 120 minutes after the EMA trigger.

Methods

Observational data were collected from 64 healthy older adults (36/64, 56% men; mean age 72.1, SD 5.6 y). Participants were asked to answer a time-based EMA questionnaire 6 times per day that assessed emotions (ie, relaxation, satisfaction, irritation, and feeling down), the physical complaint fatigue, intention, intention, and self-efficacy. An Axivity AX3 was wrist worn to capture the participants’ PA. Multilevel regression analyses in R were performed to examine these within-person associations.

Results

Irritation, feeling down, intention, and self-efficacy were positively associated with subsequent light PA or moderate to vigorous PA at 15, 30, 60, or 120 minutes after the trigger, whereas relaxation, satisfaction, and fatigue were negatively associated.

Conclusions

Multiple associations were observed in this study. This knowledge in combination with the time dependency of the determinants is valuable information for future interventions so that suggestions to be active can be provided when the older adult is most receptive.

Authors: Tarasyeva T. V.
Published: October 2023

The discrepancy between the level of qualifications and competencies of specialists produced by universities and the demand of the labor market has become the main challenge for the competitiveness and development of universities at the beginning of the XXI century. However, in recent years, the higher education sector has been characterized by the desire of universities to solve this problem by reducing the imbalance between the graduation of specialists and the needs of potential employers. In this connection, a new strategy for the development of universities aimed at shaping the content and structure of the educational process in accordance with the requirements of the labor market and the specifics of technology development at the present stage of higher education development is becoming a key factor for ensuring a sustainable pace of university development. The purpose of the study is to compare the state of the labor market in general and the labor market of young professionals with higher education for the period 2010–2021. to identify their relationship with the features of the modern strategic development of universities and to check the impact of the graduation structure in the areas of training and the relevance of the acquired competencies on the development of the labor market in the short term. The article offers a set of indicators that allows a comprehensive assessment of the situation in the labor market segment –  the labor market of young professionals with higher education. The possibility of considering the functioning of the labor market in connection with the peculiarities of modern university development significantly expands the understanding of the labor behavior of university graduates and can also be the basis for adjusting the strategic development of universities in terms of the structure of the graduation of young specialists, which together can serve as a factor in increasing the competitiveness of universities in the educational services market.
Agricultural technology adoption for smallholder small grain farmers in Zimbabwe. Implications for food system transformation and sustainability
Authors: Dube-Takaza Tryphina , Maumbe Blessing M , Parwada Cosmas
Published: October 2023

Food security is a perennial concern in natural regions IV and V of Zimbabwe, that receive low rainfall per annum. Improved small grain varieties and conservation agriculture practices provide a promise for bumper harvests in these dry regions. This study focused on four districts (Binga, Chiredzi, Hwange and Matobo) from these two regions to determine patterns for improved small grain varieties and conservation agriculture technology adoption by smallholder small grain farmers. Data were collected from 281 respondents using structured questionnaires and interviews. The statistical package Stata (version 16) was used to analyse data. Logit and multinomial models were used to compare non-adopters and adopters of technologies in order to show the rationale for adoption. Results indicated that 56% of the sample were non-adopters while 44% were adopters. Adoption patterns varied with location, education, land size, marital status, frequency of extension visits and access to credit. The study recommends increased funding to research institutions that develop high-yield small grain varieties. Comparative studies are recommended in other semi-arid regions of Zimbabwe to support the study findings in informing future policy.
Moscow in Novellas and Short Stories by S. V. Engelgardt
Authors:   Cherepovets State University, Kalitnik Anastasia A.
Published: October 2023

The article considers the concept of “Moscow text” on the material of fiction works by S. V. Engelhardt. The analysis of the novellas and short stories of the writer allows to determine the place that they occupy among other “Moscow texts” of Russian classical literature written in the 18th–19th centuries. The work of Engelhardt is considered within the framework of women’s prose of the 19th century, in accordance with the tasks that her representatives set themselves. As a result of the study, the author of the article comes to the conclusion that the image of Moscow in the works of the writer is of decisive importance and receives different interpretations. Moscow in the work of Engelhardt is presented in three main spatial and temporal plans: as a secular city (party receptions, balls, receptions), as an Orthodox city (churches, monasteries) and as a city-symbol of Russia (Time of Troubles, the reign of Catherine II, the Patriotic War of 1812). The motifs of gossip, rumors and money are connected with secular Moscow, the motifs of sin, repentance, prayer, pilgrimage are connected with Orthodox Moscow, the motif of the struggle for power and war are connected with Moscow as a symbol of Russia. Motifs of mystery, mysticism, and legends are associated with the image of Moscow, which help to present the city in an unrealistic, distorted perspective.
“The Blessed Germany” Between Emotio et Ratio: New Aspects of German Space Imagery in “Travel Letters from England, Germany and France” by N. I. Gretch
Authors:   iberian State University of Geosystems and Technologies, Zhdanov Sergey S.
Published: October 2023

The paper deals with the representation of the German space in “Travel letters from England, Germany and France” by N. I. Gretsch. This text is compared as with author’s other travelogues dedicated to traveling through German lands as well as with the tradition of describing Germany in Russian literature in the end of the 18th – the first half of the 19th centuries. The article reveals the close connection of the spatial imagery in the Gretsch’s work with the sentimentalism world-image of Germany. In accordance with this world-image, German lands are marked mainly with idyllic features. Idyllic loci in the Gretsch’s travelogue are connected with a number of motifs, such as motifs of orderliness, coziness, visual attractiveness, abundance, vitality, purity, peacefulness, silence, justice, contentment, brightness, closeness, patriarchality, achrony, miniaturization. The motif of sacredness of German space is of particular importance for representing the “blessed Germany” in the text. This allows to set the opposition “sacred, law-abiding, peaceful Germany — desecrated, lawless, violent France.”
“Unsuitable for Printing”: On the Principles of Selecting Pilgrimage Notes for Publication
Authors:   Institute of Russian Literature (Pushkin House) of the Russian Academy of Sciences, Fedorova Irina V.
Published: October 2023

In the last two decades, domestic science has been enriched by a corpus of works describing pilgrimages to the Holy Land in the 19th – early 20th centuries. This happened thanks to intensive archeographic research in Russian archives, which have preserved many texts of different genres that tell about the pilgrimage to Jerusalem. The article presents an overview of a number of such works preserved in manuscripts and / or recently published, and considers the principles that can make it possible to assess the relevance of expanding the source base for the study of domestic pilgrimage literature. These principles are based on the evaluation of the content of the work, the time of the pilgrimage, the social status of the author, the integrity of the text and the degree of its originality.

Published: October 2023

Schizothoracine fish spawning habitats in the Tibetan Plateau are poorly
understood but critical for conservation amidst anthropogenic threats
and climate change. In a 2019–2021 study, we located the spawning
grounds of Schizopygopsis microcephalus Herzenstein, 1891, at an
astounding 4800 m above sea level, the highest known fish spawning site.
This occurred in mid-June, before seasonal flooding. We found
approximately six circular egg burial nests per square meter, measuring
20–30 cm in diameter and 10–15 cm deep, nestled within gravel (4–5 cm
max diameter, D50 of 2.2 cm). Egg fertilization rates reached 98%, with
an 82% hatching rate. Intriguingly, eggs displayed delayed shell
hardening during natural incubation, possibly to protect against intense
high-elevation ultraviolet radiation. Further investigations are needed
to understand the role of the pliable membrane. Survival of the species
requires that this kind of rare habitat be conserved.
The Effect of Drainage and Afforestation on the Soil Microbial Composition of Fens Is Greater than that of Bogs in Subtropical Moss Peatlands

Published: October 2023

Subtropical moss peatlands have important ecological functions, and
their protection and restoration are urgent. In this study, typical
subtropical moss peatlands and the Cryptomeria swamp forest (CSF) formed
by long-term (more than 20 years) drainage and afforestation in the
Yunnan-Guizhou Plateau of China were selected as the research sites. 16S
rRNA high-throughput sequencing technology was used to study the
differences in soil bacterial community diversity and composition among
a natural Sphagnum fen (SF), Polytrichum bog (PB) and CSF to explore the
effects of drainage and afforestation on different types of moss
peatlands and its mechanism combined with soil physicochemical
properties. Results showed that (1) drainage and afforestation
significantly reduced the α diversity of soil bacterial communities in
SF, while significantly increased the α diversity of soil bacterial
communities in PB. Soil bacterial communities of SF had the highest α
diversity and had many unique species or groups at different taxonomic
levels. (2) The impact of drainage and afforestation on the soil
bacterial community composition in SF was significantly higher than that
in PB. Drainage and afforestation caused significant changes in the
composition and relative abundance of dominant groups of soil bacteria
in SF at different taxonomic levels, such as significantly reducing the
relative abundance of Proteobacteria, significantly increasing the
relative abundance of Acidobacteria, and significantly reducing the
ratio of Proteobacteria to Acidobacteria, but did not have a significant
impact on the corresponding indicators of PB. The changes in the ratio
of Proteobacteria to Acidobacteria may reflect changes in the trophic
conditions of peatlands. (3) Soil moisture content, available phosphorus
content, and pH were key driving factors for changes in soil bacterial
community composition and diversity, which should be paid attention to
in the restoration of moss peatlands.

Published: October 2023

composite right /left-handed transmission line metamaterial leaky wave
antenna with ability of space scan by changing frequency and at a fixed
frequency with lumped element is designed in this study. Considering the
ability to rotate antenna beam by changing the frequency of the leaky
wave antenna, the rotation of the desired antenna pattern was evaluated
by changing the frequency. The introduced antenna can scan a wide
spatial area from 〖-15〗^° to 〖+42〗^° by changing the frequency
in the 2.5 GHz bandwidth (from 9 to 11.5 GHz) without a stop band and
with maximum gain of 15 db. In the second part, by placement three
Lumped elements (capacitors) in each unit cell of mentioned CRLH-TL
leaky wave antenna that has the ability to scan the space in several
fixed frequencies (9.6-10-10.4-11 GHz) has been designed. In this case,
the antenna can scan from 〖-5〗^° to 〖+12〗^° at 9.6 GHz and
from 〖-18〗^° to 〖-46〗^° at 11 GHz with an average gain of 11
db. For wider scanning in negative and positive angles, it is suggested
to use a double-port switch to feed from both inputs of the CRLH-TL
leaky wave antenna to increase the overall space scanning angle.
Study on damage characteristics and internal variable modeling of single-fracture sandstone under coupling effect of freeze-thaw and fatigue load
Authors: CHANG PENGBO CHANG , Zhang Kun , Ren JianXi , Liu Zheng , Wang Ke
Published: October 2023

To strengthen the disaster prevention and control of engineering
fractured rock mass in the cold region of western China due to
freeze-thaw cycles, 20 freeze-thaw cycles were performed on fractured
sandstone samples with different inclination angles of 30°, 45°, 60°,
and 90°. Subsequently, conventional triaxial and fatigue loading tests
were conducted to explore the mechanical properties and fracture
morphology evolution mechanism of freeze-thaw fractured sandstone during
compression. At the same time, nuclear magnetic resonance technology was
used to analyze the microscopic damage characteristics. Based on the
internal variable theory of continuum mechanics, a fatigue model of
freeze-thaw fractured sandstone with different inclination angles was
established. The results show that the sandstone strength is negatively
correlated with the fracture dip angle, the axial deformation and shear
failure angle are positively correlated with the fracture dip angle. The
mechanical properties of the sandstone are deteriorated by fatigue
loading. The T spectrum distribution of the
fractured sandstone mainly has three peaks, and the pore distribution is
mainly medium and small pores. There is a small leftward shift after
freeze-thaw cycles and fatigue loading. The T
spectral area is significantly affected by freeze-thaw cycles and
fatigue loading, and the rate of change of both tends to increase.
Through the fine correspondence between the axial residual deformation
and the deformation modulus, a fatigue model with different crack
inclination angles was established using the axial residual deformation
as the internal variable, and the rationality of the model was verified
by fatigue loading tests.
Investigating the relative role of dispersal and demographic traits in predictive phylogeography
Authors: Mascarenhas Rilquer , Carnaval Ana
Published: October 2023

Many studies suggest that aside from environmental variables, such as
topography and climate, species-specific ecological traits are relevant
to explain the geographic distribution of intraspecific genetic
lineages. Here, we investigated whether and to what extent incorporating
such traits systematically improves the accuracy of random forest models
in predicting genetic differentiation among pairs of localities. We
leveraged available ecological datasets for birds and tested the
inclusion of two categories of ecological traits: dispersal-related
traits (i.e., morphology and foraging ecology) and demographic traits
(such as species survival rate and generation length). We estimated
genetic differentiation from published mitochondrial DNA sequences for
31 species of birds (1,801 total genetic samples, 526 localities) in the
Atlantic Forest of South America. Aside from the aforementioned
ecological traits, we included geographic, topographic and climatic
distances between localities as environmental predictors. We then
created models using all available data to evaluate model uncertainty
both across space and across the different categories of predictors.
Finally, we investigated model uncertainty in predicting genetic
differentiation individually for each species (a common challenge in
conservation biology). Our results show that while environmental
conditions are the most important predictors of genetic differentiation,
model accuracy largely increases with the addition of ecological traits.
Additionally, the inclusion of dispersal traits improves model accuracy
to a larger extent than the inclusion of demographic traits. Similar
results are observed in models for individual species, although model
accuracy is highly variable. We conclude that ecological traits improve
predictive models of genetic differentiation, refining our ability to
predict phylogeographic patterns from existing data. Additionally,
demographic traits may not be as informative as previously hypothesized.
Finally, prediction of genetic differentiation for species with
conservation concerns may require further careful assessment of the
environmental and ecological variations within the species range.

Entrepreneurship is significant in driving economic growth and job creation and can be a powerful tool for achieving the goals of gender equality and enhancing women’s empowerment. However, there is little evidence on women entrepreneurs in Asia. To support the Evidence and Data for Gender Equality (EDGE) initiative, this study examined gender gaps in entrepreneurship using unique household data collected from Georgia; Mongolia; and Cavite, Philippines. The study provides insights into women and men entrepreneurs and their activities. It suggests, using multivariate analysis, that the determinants of income vary by gender and across countries.
Sustainability-oriented route generation for ridesharing services
Authors: Liu Mengya , Yazdanpanah Vahid , Stein Sebastian , Gerding Enrico
Published: October 2023

Sustainability is the ability to maintain and preserve natural and manmade systems for the benefit of current and future generations. The three pillars of sustainability are social, economic, and environmental. These pillars are interdependent and interconnected, meaning that progress in one area can have positive or negative impacts on the others. This calls for smart methods to balance such benefits and find solutions that are optimal with respect to all the three pillars of sustainability. By using AI methods, in particular, genetic algorithms for multiobjective optimisation, we can better understand and manage complex systems in order to achieve sustainability. In the context of sustainability-oriented ridesharing, genetic algorithms can be used to optimise route finding in order to lower the cost of transportation and reduce emissions. This work contributes to this domain by using AI, specifically genetic algorithms for multiobjective optimisation, to improve the efficiency and sustainability of transportation systems. By using this approach, we can make progress towards achieving the goals of the three pillars of sustainability.
Efecto de la deshidratación de desechos de tomate en el contenido de compuestos fenólicos, carotenoides y capacidad antioxidante
Authors: Armenta Gorosave Julio Cesar , Méndez-Trujillo Vianey , Gonzalez Mendoza Daniel , González-Valencia Daniela Guadalupe , Olvera-Sandoval Carlos
Published: October 2023

En México, el desperdicio de tomates puede relacionarse con la deficiencia en la cadena de transporte y almacenaje, bajos estándares de calidad del producto, deficiencias en la exhibición del producto y fallas en la coordinación con proveedores. Estos factores contribuyen al desperdicio de tomate para su consumo por no cumplir con los estándares impuestos por los mercados de alimentos y el consumidor final. No obstante, los desperdicios de tomate pueden ser revalorizados y ser una fuente de fitoquímicos con relevancia nutrimental. El objetivo del presente estudio fue identificar el efecto de la temperatura de secado de frutos de tomate considerados de desperdicio evaluando su capacidad antioxidante, compuestos fenólicos, carotenoides, azúcares reductores, proteínas, humedad y cenizas. Se realizaron tres tratamientos para medir el efecto del secado a 24, 48 y 72 horas a tres temperaturas diferentes 50, 60 y 70 °C en las muestras de frutos de tomate colectadas. Los resultados mostraron que el tratamiento de secado a 50 °C por 72 horas arrojo los mayores valores de proteínas (45,3 g/kg) y azúcares reductores (196 mg/g). Por su parte el tratamiento de 70 °C mostró incrementos en compuestos fenólicos (48,12 mg/g), licopeno (2503 µg/g) y β-caroteno (31,84 µg/g) a las 24 horas de secado. Estos resultados indicaron que al exponer la biomasa de tomate a una temperatura de 70 °C por 24 horas correspondiente al Tratamiento (T4 - 1), se produjo una mayor biosíntesis de compuestos bioactivos que podrían ser empleados en la formulación de nuevos productos alimenticios, por ejemplo, en la elaboración de tortillas.

Characterization of Electrodeposited Cobalt/Copper (Co/Cu) Granular Multilayered Thin Films onto the Anodic Aluminum Oxide (AAO) Substrates
Authors: Bantu Albert Kazadi Mukenga
Published: October 2023

Herein, we report on the characterization of a series of cobalt/copper granular thin films alloys electrodeposited onto the previously pre-treated aluminum substrates, at different deposition time. And a systematic study of their structural and magneto-optical properties were investigated. The proper deposition potentials of Co, and Cu were obtained from the cyclic voltammetry method. It was observed that the easy axis direction of magnetization was parallel to the film plane for all films. The X-ray diffraction (XRD) results revealed that all films had a mixture of hexagonal close-packed (hcp) and face centered cubic (fcc) phases. The Scanning electron microscope images (SEM) and atomic force microscopy (AFM) showed some parallelepiped and ellipsoid shaped rods with an averaged dimension about of 600 nm length, 600 nm width and 200 nm thickness for a sample electrodeposited at room temperature. These rods are irregularly arranged. Their irregular arrangement could explain the large d-spacing in the sample at this temperature. The magnetic analysis of the granular thin films alloys showed the saturation magnetization increased and the coercivity decreased as the deposition time increased. These results showed that the changes in magnetic and structural properties of granular cobalt/copper alloys deposits were substantially depending on the variation of deposition time. Therefore, the change of the deposition time was seen to control the properties of the alloys deposits and hence their properties could be modified for desired purpose.

Preparation, Characterization and Application of Niosomes for the Delivery of Herbal Bioactive Agents: A Mini Review
Authors: Roy Probin Kr
Published: October 2023

The demands of herbal products including Nutraceuticals, cosmetics and drugs increased tremendously globally in recent times. Herbal compounds offer limited toxicity, high biocompatibility with numerous health benefits. The herbal drugs show many health benefits due to their presence of bioactive compounds in it. However, bioactive compounds suffer due to their poor solubility, poor bioavailability and stability. Niosomes, a non-ionic surfactant vesicle, can be a promising aspect to deliver the bioactive compound to enhance the bioavailability and stability. Niosomes have many advantages as it enables encapsulation of either hydrophilic and hydrophobic compounds. Preparation methods of niosomes are also simple and inexpensive. Moreover, encapsulating bioactive compounds in niosome not only improve the bioavailability but also enable it for sustained release or controlled release drug delivery.

Authors: Chowdhury Kakali
Published: October 2023

The problem of MHD mixed convection is analyzed in a lid driven cavity with corrugated wavy bottom wall filled with Cu-H2 O nanofluid in presence of internal heat source. The top and right walls of the cavity are maintained with a uniform cold temperature whereas the left wall and bottom wavy wall are kept adiabatic. The top wall is moving with a constant velocity upon its lid and a rectangular heat source is placed horizontally inside the cavity. The physical problem is characterized by 2D governing partial differential equations along with proper boundary conditions and are discretized using Galerkin’s finite element formulation. The study is executed by analyzing different ranges of geometrical, physical and nondimensional parameters namely, wave number of wavy surface (0 ≤ ≤ λ 4) , the ratio of heat source height and cavity height 1 3 1 20 a l  ≤ ≤      volume fraction of nanoparticle (0 ≤ ≤ ϕ 0.09) Hartmann number (0 ≤ ≤ Ha 90) and Richardson number (0.1≤ ≤ Ri 10) . The results indicate that heat transfer rate decreases with the increasing value of heat source height and cavity height ratio a L       . It decreases about 9% and 25% with the increasing ratio of a L from 1 20 to 1 10 and 1 5 respectively. It also reveals that heat transfer rate increases with the increasing value of wave number of corrugated wall. At Ri=1 and Ha=0 heat transfer rate increases about 9% and 16% with the increasing value of λ from 0 to 2 and 4 respectively for nanofluid with 6% of nanoparticle.

Supplementary effects of Noug Seed (Guizotia abyssinica) Cake with Sesbania (Sesbania sesban) Leaves on Feed Intake, Digestibility and Enteric Methane Emission in Arsi-Bale Sheep
Authors: Dufera Mr Birhanu
Published: October 2023

An experiment was conducted to study the effects of feeding the mixture S. sesban (Sesbania sesban) leaves, noug seed cake, and hay on feed intake, digestibility, and estimating enteric methane emission of Arsi-Bale sheep. The experiment was done having the nine-adult sheep of initial body weight 26.7 (±0. 14) kg. The experiment consisted of 7 days of digestibility and 90 days of feeding trials. The experiment employed a 3 x 3 cross over design with three treatments and three periods. There were three treatments including S. sesban leaves alone (T1), 27.6% S. sesban leaves + 27.6% hay +44.8% Noug seed cake (NSC) (T2) and 38.6% + 61.4% NSC (T3). Total dry matter intake (DMI) was higher (P<0.001) for sheep feed in 27.6% + 27.6% hay + 44.8% NSC (706.9g/day) compared to the rest of the treatments. However, the effect of S. sesban leaves alone decrease the total DMI. Digestibility of DM, OM, CP (P<0.01), NDF, and ADF were higher (P<0.05) between the treatments. Average daily gain (ADG) was higher (P<0.01) for sheep in feed 27.6% S.sesban leaves + 27.6% hay + 44.8% than those in feed S. sesban leaves alone. Increased level of S. sesban leaves supplement, in general, reduced growth in this study. However, there was no difference between 27.6% S.sesban leaves + 27.6% hay + 44.8% and 38.6% hay + 61.4% NSC. Estimation of enteric methane emissions factor and daily methane production was higher (P<0.01) in treatments T2 as compared to T3 and T1. And also, T3 higher than T1. Thus, it can be concluded that S. sesban leaves can be promoted as valuable feed resources for ruminants while concurrently reducing methane emissions.
Exploring Socio-Cultural Hybridity and the Role of Indigenous Postharvest Practices in Northern Uganda: The Case of Kwania and Kole Districts
Authors: Nkobou Atenchong Talleh
Published: October 2023

Background: There is growing recognition that addressing food and nutrition (in)security requires an acknowledgement of the plurality of knowledge systems, including indigenous management practices. This paper relies on quantitative research strategies to explore 'socio-cultural hybridity' as a bridge between low levels of 'modern' technology adoption and the loss of indigenous postharvest management practices. The results presented here partly informed a more participatory project on indigenous knowledge in Northern Uganda, and has wider implications for interventions towards postharvest food loss and waste in rural communities globally. Data was collected in Uganda’s Kwania and Kole Districts between June and July 2022 (n=213). We uniquely calculate reliance levels on post-harvest management practices using ordinal data. Results: Although sex does not significantly impact reliance on indigenous knowledge and practices (IK_Score), the coefficient of the sex variable shows that men have an IK_Score 0.87 units lower than women, explained by the skewness of access to education (p= 0.044) towards men. Secondary and tertiary educated participants had a lower IK_Score than those without formal education. Additionally, age was statistically significant on the IK_Score. Participants above 70 (p=0.01E-6) have an IK_Score 24.1 units higher than those aged between 19-35. Tertiary/university-level education has a significant impact (p=7.50E-6) reliance on modern technology (MT_Score). The importance of 'social situatedness' e.g., belonging to farmers group, is essential for 'cultural mixing' and explains the importance of social variables on adopting modern technology. Participants who belong to farmers groups (p=0.034) had a higher MT_Score. Although income was not a statistically significant variable for the IK_Score, income was statistically significant for the MT_Score (p=1.2E-4), which ultimately affects cultural mixing. Conclusion: Modernisation variables, such as education and income, significantly impact smallholder farmers' willingness to change. Finally, social situatedness, such as belonging to farmer's groups positively impacts socio-cultural hybridity. If researchers, policymakers and practitioners continuously fail to account for local and indigenous knowledge systems, the actual agents of change in rural communities may be continuously side-lined in their efforts towards reducing postharvest losses. Identifying these socioeconomic factors provides opportunities to review approaches to reducing postharvest management practices in these rural settings.
