cuFastTucker: A Novel Sparse FastTucker Decomposition For HHLST on Multi-GPUs
Authors: Li Zixuan , Hu Yikun , Li Mengquan , Yang Wangdong , Li Kenli
Published: April 2024

High-order, high-dimension, and large-scale sparse tensors (HHLST) have found their origin in various real industrial applications, such as social networks, recommender systems, bioinformatics, and traffic information. To handle these complex tensors, sparse tensor decomposition techniques are employed to project the HHLST into a low-rank space. In this article, we propose a novel sparse tensor decomposition model called Sparse FastTucker Decomposition (SFTD), which is a variant of Sparse Tucker Decomposition (STD). The SFTD utilizes Kruskal approximation for the core tensor, and we present a theorem that reduces the exponential space and computational overhead to a polynomial one. Additionally, we reduce the space overhead of intermediate parameters in the algorithmic process by sampling the intermediate matrix. Furthermore, this method guarantees convergence. To enhance the speed of SFTD, we leverage the compactness of matrix multiplication and parallel access through a stochastic strategy, resulting in GPU-accelerated cuFastTucker. Moreover, we propose a data division and communication strategy for cuFastTucker to accommodate data on Multi-GPU setups. Our proposed cuFastTucker demonstrates faster calculation and convergence speeds, as well as significantly lower space and computational overhead compared to state-of-the-art (SOTA) algorithms such as P-Tucker, Vest, GTA, Bigtensor, and SGD_Tucker.

We undertook a comprehensive investigation of the the structural, dielectric, and electrical characteristics of Pb(Sn0.45Ti0.55)O3 ceramics prepared using the conventional solid-state route. A meticulous preparation protocol, involving solvating various precursors, was followed by extensive characterization employing X-ray diffraction, scanning electron microscopy, and dielectric studies. The synthesized sample features a single-phase tetragonal structure with P4mm symmetry. Using impedance spectroscopy, electrical transport properties of the polycrystalline Pb(Sn0.45Ti0.55)O3(PST) ceramic were studied in detail. Relaxation and conduction mechanisms of the material were inferred using complex impedance, complex electric modulus, and frequency dependent ac conductivity analysis. Impedance spectroscopy results reveal the range of frequencies in which the grain, grain boundary, and electrode effects are dominant. Above certain temperatures, the imaginary component of impedance (Z//) exhibits some resonant type peaks at different frequencies indicating relaxor nature of the sample. The activation energy obtained for both the relaxation and conduction process indicates the role of doubly-ionized oxygen vacancy in the conduction mechanism of the sample. The dielectric relaxation occurring at low frequency and high temperatures is related to the space charges associated with the ionized oxygen vacancies being trapped at the grain boundaries. The Cole-Cole plots confirm the poly-dispersive nature of dielectric relaxation in the sample.

Published: April 2024

Over the past few decades, Polyvinyl-alcohol (PVOH)/cornstarch (CS)-based composite thin films have garnered significant interest due to their enhanced properties. Synthesis of such films relies heavily on depolymerization reactions within the solution of the PVOH/CS blends. Understanding how depolymerization affects the crystal structure and properties of these films is crucial for further improvement. This study aims to evaluate the depolymerization effects of crosslinked PVOH incorporated with CS as filler materials (with an 80:20 mass ratio) using ultrasonication at various time intervals while maintaining a constant frequency of 25 KHz. The prepared solution is then cast into thin films using blade coating. Comparative analyses were then conducted between samples subjected to ultrasonication (treated) and without ultrasonication (untreated) to assess their properties based on structural physical, mechanical, optical, and aspects of biodegradability . The investigation revealed significant changes in crystal structure and lattice strains following ultrasonication of the PVOH/CS solution when compared to untreated PVOH/CS samples. Importantly, longer ultrasonication times correlated with increased tensile strength. Additionally, the treated samples led to improvements in thin film transparency and a notable decrease in absorbance. These changes were attributed to the mechanical depolymerization induced by ultrasonication, aligning the thin films with the necessary properties for food packaging applications.

Published: April 2024

High levels of oxidant stress in the form of reactive oxidant species are prevalent in the circulation and tissues in various types of cardiovascular disease including heart failure, hypertension, peripheral arterial disease, and stroke. Here we review the role of nuclear factor erythroid 2-related factor 2 (Nrf2), an important and widespread antioxidant and anti-inflammatory transcription factor that may contribute to the pathogenesis and maintenance of cardiovascular diseases. We review studies showing that downregulation of Nrf2 exacerbates heart failure, hypertension, and autonomic function. Finally, we discuss the potential for using Nrf2 modulation as a therapeutic strategy for cardiovascular diseases and autonomic dysfunction.

Authors: Helal Ayah , Zawawi Zahraa
Published: April 2024

The 10 major cities in the West Bank (WB), Palestine—Nablus, Ramallah and Al‐Bireh, Jenin, Qalqilia, Salfit, Tubas, Jericho, Bethlehem, Tulkarem, and Hebron—are experiencing rapid urban transformation and changing land cover. This study explores the relationship between land cover (built‐up and unbuilt areas) and soil type in these cities across benchmark years 1995, 2000, 2005, 2010, 2015, and 2021. In addition to the former, the paper argues that the expansion and increase of the built‐up area and the change in soil type of the aforementioned cities in the West Bank, Palestine, are leading to changes in the land surface temperature (LST). This conclusion was reached through a methodological framework that was developed to measure the relationship between the changing land cover (built‐up and unbuilt‐up areas), soil type, and LST in the 10 major cities in the region. The framework relies on data retrieved through remote sensing in the years from 1995 to 2021. The results of the analysis conducted through this methodological framework showed that there is an inverse relationship between the increase in built‐up areas and LST; however, LST is less inside the built‐up areas than in the surrounding areas (open spaces) due to different land cover (unbuilt area with grass and shrubs) and different soil type.
Enhancing Thermal Insulation of Poly(β‐Hydroxybutyrate) Composites with Charring‐Foaming Agent‐Coated Date Palm Wood
Authors: Mlhem Amal , Abu-Jdayil Basim , Iqbal Muhammad Z.
Published: April 2024

Date palm fiber (DPF) holds great potential for composite materials, but its flammability limits its practical applications. In this study, DPF was modified using a pad‐drying method to impregnate it with a 5 wt.% solution of ammonium dihydrogen phosphate (ADP). These treated fibers were then utilized to fabricate poly(β‐hydroxybutyrate)‐ (PHB‐) based composites. The resulting thermal insulators were comprehensively evaluated for their flammability, physical, mechanical, and thermophysical properties, as well as morphological and thermal stability characteristics. The findings revealed a significant reduction in flame spread and smoke suppression; however, the concentration used is not sufficient to achieve the desired rating grades. The thermal insulation capacity of the modified fiber composites was substantially enhanced, particularly with the 40% PHB/DPF‐ADP composite displaying the lowest thermal conductivity at 0.0564 W/m.K. Moreover, the presence of gaps and voids at the interface led to a reduction in tensile strength to 4‐7 MPa. Additionally, the modified fiber composites exhibited significantly reduced water absorption (~0.76%), attributed to the formation of a highly water‐resistant substance containing a furan compound. This work provides a simple and effective approach for achieving durable flame retardancy and long‐term thermal insulation performance, offering promising opportunities for the practical application of biobased PHB composites.

Published: April 2024

Background. Suicide is a pressing global health concern, and identifying its risk factors is crucial for prevention. Body weight variability (BWV) has been increasingly recognized as a potential factor impacting physical and mental health outcomes. We aimed to explore the relationship between BWV and the risk of suicide mortality using a nationally representative database. Methods. This population-based cohort study used data from the Korean National Health Insurance Database and included a total of 1,983,701 subjects. BWV was assessed using at least three health examination datasets and validated variability indices (variability independent of the mean (VIM), average successive variability, and coefficient of variation), and patients were divided into BWV quartiles (Q1–Q4). The primary endpoint was suicide-related death. Results. During a median of 11.3 years of follow-up, 5,883 suicide deaths occurred. A higher baseline body weight was associated with a lower risk of suicide. However, greater BWV (VIM) was associated with a significantly greater risk of suicide (adjusted hazard ratio [95% confidence interval], 1.35 [1.26–1.45] in the Q4 group), even after adjusting for baseline body mass index (BMI). Similar results were observed regardless of obesity or BMI category. Consistent findings were observed when using different variability indices. Subgroup analyses according to sex, age, diabetes, and depression also supported these findings. Conclusion. Our study highlights the importance of considering BWV as a potential risk factor for suicide.
Effects of Gas‐Diffusion Layers and Water Management on the Carbon Corrosion of a Catalyst Layer in Proton‐Exchange Membrane Fuel Cells

Published: April 2024

Carbon corrosion in a catalyst layer (CL) deteriorates the performance and durability of proton‐exchange membrane fuel cells (PEMFCs), which are closely related to water management within these cells. This study investigates the characteristics of water behavior of two gas diffusion layers (GDLs) and compares their influence on degrees of degradation in the CL. First, the properties of the GDLs, including their thickness, pore size distribution, gas permeability, electrical resistance, contact angle, and polytetrafluoroethylene (PTFE) content, are evaluated. The dynamic behavior of liquid water is observed using a visualization cell and synchrotron X‐ray imaging. Second, a modified accelerated stress test (AST), which includes a water generation reaction within the catalyst support protocol of the US Department of Energy (DOE), is performed. For assessing the degradation, we utilize polarization curves, electrochemical impedance spectroscopy, cyclic voltammetry, scanning electron microscopy, and field emission transmission electron microscopy. The results reveal that, even though GDL B contains a higher hydrophobic content than GDL A, it exhibits lower water discharge, indicating a reduced performance at high relative humidity (RH) levels. This is attributed to a low capillary pressure gradient, which is influenced not only by PTFE but also by the overall pore structure (i.e., porosity and pore size). Consequently, a high capillary pressure gradient can enhance water discharge and thereby mitigate carbon corrosion and Pt agglomeration in the CL. In addition, the application of the modified AST induces carbon corrosion with fewer cycles than that achieved using the DOE carbon support protocol.

AbstractPurpose:
Despite efficacy of approved FGFR inhibitors, emergence of polyclonal secondary mutations in the FGFR kinase domain leads to acquired resistance. KIN-3248 is a selective, irreversible, orally bioavailable, small-molecule inhibitor of FGFR1-4 that blocks both primary oncogenic and secondary kinase domain resistance FGFR alterations.
Experimental Design:
A first-in-human, phase I study of KIN-3248 was conducted in patients with advanced solid tumors harboring FGFR2 and/or FGFR3 gene alterations (NCT05242822). The primary objective was determination of MTD/recommended phase II dose (RP2D). Secondary and exploratory objectives included antitumor activity, pharmacokinetics, pharmacodynamics, and molecular response by circulating tumor DNA (ctDNA) clearance.
Results:
Fifty-four patients received doses ranging from 5 to 50 mg orally daily across six cohorts. Intrahepatic cholangiocarcinoma (48.1%), gastric (9.3%), and urothelial (7.4%) were the most common tumors. Tumors harbored FGFR2 (68.5%) or FGFR3 (31.5%) alterations—23 (42.6%) received prior FGFR inhibitors. One dose-limiting toxicity (hypersensitivity) occurred in cohort 1 (5 mg). Treatment-related, adverse events included hyperphosphatemia, diarrhea, and stomatitis. The MTD/RP2D was not established. Exposure was dose proportional and concordant with hyperphosphatemia. Five partial responses were observed; 4 in FGFR inhibitor naïve and 1 in FGFR pretreated patients. Pretreatment ctDNA profiling confirmed FGFR2/3 alterations in 63.3% of cases and clearance at cycle 2 associated with radiographic response.
Conclusion:
 The trial was terminated early for commercial considerations; therefore, RP2D was not established. Preliminary clinical data suggest that KIN-3248 is a safe, oral FGFR1-4 inhibitor with favorable pharmacokinetic parameters, though further dose escalation was required to nominate the MTD/RP2D.
Significance:
KIN-3248 was a rationally designed, next generation selective FGFR inhibitor, that was effective in interfering with both FGFR wild-type and mutant signaling. Clinical data indicate that KIN-3248 is safe with a signal of antitumor activity. Translational science support the mechanism of action in that serum phosphate was proportional with exposure, paired biopsies suggested phospho-ERK inhibition (a downstream target of FGFR2/3), and ctDNA clearance may act as a RECIST response surrogate.

Introduction: Alzheimer's disease (AD) is an irreversible neurodegenerative disorder characterized by the deterioration of cognitive functions, for which the available pharmacotherapy is not capable of effecting a cure. Objectives: To investigate the neuroprotective properties of phytoconstituents from Jaborandi (Pilocarpus microphyllus) and propolis as potential agents in the therapy of AD. Methodology: This is an integrative literature review study, in which the PICO strategy was followed in formulating the guiding question. Five databases were used: PubMed, Web of Science, Scopus, Embase, and Lilacs. The analysis was conducted with the descriptors "epiisopiloturine", "episopilosin", "pilocarpine", "macaubine", "propolis", "alzheimer" extracted from the DeCS (Health Sciences Descriptors) and Medical Subject Headings (MeSH). Keywords were isolated and combined using boolean operators AND and OR. Results: The search resulted in 602 studies identified in the databases, 337 were duplicates, leaving 265 for title and abstract reading, of which 250 were excluded. In the end, 10 studies were read in full and 08 studies were included in the scope of the review. The research evidenced neuroprotective activity for propolis, through antioxidative, anti-inflammatory, and anticholinesterase action, configuring it with therapeutic potential in AD. For pilocarpine, a substance with various clinical applications, few studies demonstrated a correlation with AD, in cognitive and behavioral improvement. Conclusion: Therefore, benefits for the use of propolis in cognitive dysfunctions are concluded, while for pilocarpine, this relationship was not established. It is necessary to develop research that elucidates the possible functional roles for these substances.

Published: April 2024

Leptocoris arabicus new species (Hemiptera: Heteroptera: Rhopalidae: Serinethinae) is described based on 55 specimens of both sexes collected in various localities of southern Oman and southeastern Yemen; a hypothesis is proposed as to its host plant. The new species is close to Leptocoris amictus Germar, 1838 and to Leptocoris ruber Göllner-Scheiding, 1980, new status, due to the presence of a produced horned process along the posterior ventral margin of the genital capsule. It is distinguished from both by differences in colour pattern and morphology. An informal L. amictus species-subgroup is proposed to accommodate these three species within the Leptocoris hexophthalmus species-group sensu Göllner-Scheiding (1980). The following new faunistic records are also provided: L. amictus from Ethiopia, Mozambique and Zambia; L. ruber from Central African Republic. The occurrence of L. chevreuxi (Noualhier, 1893) in Oman is confirmed. The list of all available species-group names assigned to Leptocoris Hahn, 1833 (gender masculine) and their synonyms is compiled and the gender agreement is corrected in the species names when appropriate. The nomenclatural problem concerning Leptocoris living on Marshall Islands discovered by Kerzhner (2003) is discussed and the following corrections are provided: Leptocoris rufus rufus Hahn, 1833, new status = Leptocoris lariversi Usinger, 1952, new synonymy, and Leptocoris rufus isolatus (Distant, 1914) new status.

Authors: Du Weigang , Pang Zhenli , Cao Zhi , Xu Guoqiang
Published: April 2024

This study focuses on the selection and application of wax removal techniques tailored for fixed tubing columns in offshore wells that have been obstructed by wax deposits. Initially, the paper delves into the importance of well decommissioning and examines prevalent decommissioning techniques, outlining their respective advantages and limitations. Subsequently, three distinct unblocking technologies are proposed, tailored to address different causes and scenarios of well clogging: physical plugging removal technology, chemical treatment technology, and mechanical unblocking technology. Each technology is thoroughly analyzed, discussing their applicable scopes, operational procedures, equipment and anticipated effectiveness in removing blockages. To validate the feasibility and practicality of these proposed unblocking methods, an actual offshore well case study is conducted. The results demonstrate that thermal nitrogen wax removal technology emerges as the most effective approach, necessitating further optimization of its application. The paper then details the oil-filed implementation of this technology, including methods for generating hot nitrogen and its subsequent application. Following the implementation, significant improvements in wax removal and unblocking are observed, attesting to the technology's effectiveness. The findings of this study offer valuable insights and practical guidance for addressing wax blockage issues in fixed tubing columns of offshore oil wells. By providing a comprehensive analysis of different unblocking techniques and their application in oil-filed, this paper contributes to enhancing the efficiency and reliability of offshore oil production operations.
Sea Surface Temperature Prediction in China Sea Based on SAM-LSTM Approach
Authors: Song Jiali , Zhang Xueqing , Jiang Wensheng
Published: April 2024

Sea Surface Temperature (SST), a critical environmental element in the ocean, significantly impacts the global atmosphere-ocean energy balance and holds the potential to trigger severe weather like droughts, floods, and El Niño events. Therefore, the prediction of future SST dynamics is crucial to identifying these extreme events and mitigating the damage they caused. In this study, we introduce a time series prediction method based on the Self-Attention Mechanism-Long Short-Term Memory (SAM-LSTM) model. In addition, the historical time-series satellite data of SST anomaly (SSTA) is used instead of SST itself considering that the fluctuations of SST are very small compared to their absolute magnitudes. The Seasonal-Trend decomposition using Loess (STL) method is adopted to decompose the complex non-linear SSTA time series into trend components, seasonal components, and residual components. Then, the deseasonalized time series data at 6 locations in the Bohai Sea are used to train and valid the developed SAM-LSTM model. After that, the validated models are applied to the Yellow Sea, East China Sea, and South China Sea. The experimental results show that the combination of STL time series decomposition and SAM-LSTM can achieve high-precision prediction of daily SSTA than LSTM. This suggests that the methodology used in this paper has a good application for short-term daily SST prediction.
The Distribution of Risk Across Healthcare Providers and Reducing Misclassification
Authors: Cecil William
Published: April 2024

Four linear multilevel mixed-risk models were compared using model assumption tests and predictions. Models varied by the number of random intercepts from 1 to 4, producing 2-level through 5-level models of the same measure, operative time. Normality of the dependent variable and residuals, variance homoscedasticity, level-1, and level-2 exogeneity were tested using the robust test of the level-1 residuals variance by surgeon, estimates of density, skew, and the Hausman test. Measure (operative time by hospital and surgeon) aberrancy and risk classification were evaluated using traditional methods and used to assess distribution measures. The dependent variable and the level-1 residuals required transformation for linearity and variance stabilization, respectively. Normality criteria were met for both level-1 and level-2 residuals and standardized residuals. The likelihood ratio comparing the four models was significantly larger for the 5-level (1016.1; P<0.00005) model than the likelihood ratio for the four-level and other models. Shrinkage was greatest for the 2-level model (0.039; P<0.00005) and least for the 5-level model (0.028; P<0.00005). Level-1 variance homoscedasticity was confirmed by the robust variance test across all models (P>F=1). Aberrant value detection did not require the exclusion of any observations, while prediction intervals revealed low or high risk for 54.2% of surgeons for the 2-level model and 8.6% for the 5-level model. The traditional (c2 = -11.01; P=1) and instrumental variable (c2 = 21.06; P=1) Hausman tests show that the null hypothesis cannot be rejected for level-1 or level-2 exogeneity. Once level-1 and level-2 exogeneity was confirmed, and since deconfounding was a model consideration, causal inferential capacity was assumed. The likelihood ratio, residual variance, shrinkage, and predictions show that the 5-level model is preferred to the other models.

Knowledge of the relationship between pregnancy and oral health is a public health issue. The aim of this study was to assess the knowledge, attitudes and practices of pregnant women regarding oral health in the University Hospital Centers (UHC) of Ouagadougou in 2023. This was a descriptive cross-sectional study from July to September 2023. Data were collected prospectively, and knowledge, attitude and practice scores were generated. A total of 400 pregnant women were included. The [25-34] age group was the most represented at 54%, and 56.3% of women were in their 3rd trimester of pregnancy. The majority had a secondary level school and didn’t have a treating dentist. More than half (51.2%) of the respondents had poor overall knowledge of the relationship between oral health and pregnancy, 76.3% had poor attitudes and 79.5% poor practices, resulting in a poor overall KAP level for their oral health (60.5%). There was a significant variation in KAP level according to level of education (p= 0.015) and according to the information received on oral health and its implications for pregnancy (p = 0.028). Pregnant women's knowledge, attitudes and practices regarding their oral health are inadequate. Most women were unaware of the potential consequences of oral health neglect on pregnancy and their unborn child. Efforts must be made to educate them about oral health, with a focus on prevention.

The paper report a result of an investigation in the moderating influence of economic development on the relationship between zakat success factors and compliance to pay zakat, focusing on key factors such as zakat awareness, support for zakat practices, understanding zakat application, and willingness to implement zakat. Data from 250 respondents within the General Authority of Zakat and Tax (GAZT) in Saudi Arabia were collected using a quantitative approach using questionnaires. Analysis was conducted utilizing AMOS 20 and SPSS 20.1 software. The study reveals a positive direct effect of zakat success factors on compliance to pay zakat, with economic development playing a crucial moderating role. This underscores the significance of economic development in influencing the relationship between zakat awareness, support for zakat practices, and zakat compliance. The practical implications extend to zakat institutions, urging them to enhance strategies for transparency and compliance by securing additional resources for development and organizing educational initiatives to cultivate positive attitudes towards zakat. The research contributes uniquely to the literature by incorporating economic development as a mediator in the zakat success factors and compliance relationship, offering valuable insights for researchers, economists, and zakat institutions. The findings emphasize the multifaceted impact of zakat on economic structures, social transformation, poverty reduction, and inequality. Additionally, the study highlights zakat's role in achieving sustainable economic growth and reducing social issues, advocating for its integration as a financial system to address challenges in the Muslim world. Despite limitations in respondent selection and timeframe, the research opens avenues for future studies, suggesting a broader exploration of Zakat's impact on sustainable development, climate change, wealth distribution, and economic transformation.

Published: April 2024

This manuscript was a study which focused on the effects of bullying learners with Autism Spectrum Disorder in mainstream. The main objectives of the study were to assess the reasons of bullying learners with autism Spectrum Disorder, to establish how bulling affected learners with autism and to find out interventions the school had to put in place to stop bullying of learners with Autism Spectrum Disorder. The study was conducted at the special unit at the mainstream and homes for learners with autism because that is where these learners were found. The study was qualitative in nature. Thus the instruments for data collection were the focused group discussion for parents, special education teachers, regular teachers and school administrators, structured interview guide for regular and Guidance teacher and lastly observation checklist for parents. The study revealed that the reasons for bulling learners with autism were as a result of failing to socialize with peers, being violent towards friends and having an antisocial behavior, failing to speak properly when with friends and not looking at the person they were talking to. The study also established the negative effects bulling had on these leaners such as increased violence, changing of antisocial behavior from bad to worse, they became more depressed and their low self-esteem became worse too. With regards interventions that were put in place by the school to stop bullying of learners with autism, the school plan helped learners develop and regain their loss of confidence by involving them in school activities such as academic work and giving them simpler work and reward them through praise or giving them something for doing something commendable, by helping them improve on their social interactions through encouraging them to interact more frequently with peers in order to correct their lost confidence. Suggested recommendations from the study includes, putting up a deliberate policy by the school to help autistic learners develop commutative skills, socialize frequently and positively with peers at least every day. Introduction of anti-bullying club at school to make other learners respect and accept these children’s condition without segregation. It was also recommended that the future study on the effects of bulling learners with autism in the mainstream would be necessary to establish more challenges faced by these learners in the mainstream and the research concerning autistic learners should be included in all mainstream schools in central province of Zambia in order to help these learners fully.

Potato (Solanum tuberosum L.) is one of the most important vegetable crop in the world and it is fourth among food crops after rice, wheat and maize. Potato is widely cultivated for its cheap source of carbohydrates, vitamins (B1 and C) as well as minerals. In Cameroon, where potato provides a livelihood for most producers, especially in the Western highland, production is challenged by unavailability of appropriate seeds of local varieties or Cameroon improve varieties. Many decades ago, some improved varieties (Cipira and Jacob) were released by the Institute of Agricultural Research for Development, (IRAD) Bambui, North West Region, Cameroon. The current study evaluated the performance of these varieties considering seed sizes. Four seed sizes (20 mm, 25 mm, 30 mm and 35 mm diameter) and two varieties (Cipira and Jacob) were evaluated in a randomized complete block trial in Bambili in 2022. Growth parameters such as plant emergence, plant height, vigour and number of stems did not vary significantly for different seed sizes (P > 0.05) nor for varieties (P > 0.05). However, they tend to increase with increase seed size. The number of plants at harvest followed a similar pattern as the growth parameters. The highest number of tubers harvest for both varieties were obtained from tuber seed size of 35 mm. The total weight of harvested tubers was 3.87 Kg/plot, 2.9 Kg/plot, 2.8 Kg/plot and 2.73 Kg/plot from 35 mm, 30 mm, 20 mm and 25 mm, respectively for Cipira (P < 0.05). It was 3.77 Kg/plot, 3.3 Kg/plot, 2.6 Kg/plot and 2.5 Kg/plot from seed sizes of 35 mm, 30 mm, 25 mm and 20 mm, respectively for Jacob (P < 0.05). For improved yield, Cipira at 30 mm and 35 mm seed sizes are recommended.

The study also aimed to create awareness and develop confidence among silkworm producers, development agents, agricultural experts and policy makers for wider dissemination. Nine kebeles’ (the lowest administrative level), were selected from three (3) districts for the purposes of this study. Five (5) farmers from each kebele were selected, totaling 45 farmers, for technology pre-scale up and promotion. Three rounds of theoretical and practical training were given to these farmers after they were selected. Training in the third round focused on managing row silk and cocoons after harvest, with a first round that covered broad knowledge and the importance of sericulture. Of the farmers who were chosen and trained, 95.6 percent were women who began raising silk worms, producing cocoons, and processing row silk. Each farmer received 30 kilograms of castor seed and 50 disease-free adult moths for pre-scaling up and promotion of the technology. During the first year of the study period, 90%, 50%, and 40% of the disease-free moths that were disseminated laid eggs and developed into cocoons at Shebadino, Tula sub city and Wondogenet districts respectively. Sericulture is very beneficial to young people, particularly women, in terms of providing a variety of employment options and viable income without affecting their regular agricultural activities or the existing sociocultural equilibrium. Sericulture technology with its package used, knowledge and skill of the farmers (users) on the technology upgraded, continuous follow up assured by DAs and experts. This study highlights the significance of sericulture for rural development and offers insightful information for its dissemination.
