The need for adoption of improved technologies to address challenges in small-scale cassava processing in Ghana
Authors:   Kwame Nkrumah University of Science and Technology, Amoah F , Akowuah JO , Bobobee EYH
Published: September 2022

The cassava processing industry in Ghana is dominated by small-scale processors who contribute valuably in terms of processed products such as gari, cassava flour, and cassava dough, among others, and as a result play a major role in the postharvest food system of the country. Their activities depend mostly on traditional methods of processing which have limitations in relation to the quality and quantity of the processed cassava products. They also rely mostly on manual labour which can be slow, costly or unavailable. Mechanisation of key operations in cassava processing activities has been identified as a means of increasing production, reducing postharvest losses as well as saving time. This study sought to assess the need for adoption of interventions to address challenges encountered during processing of cassava into a local staple known as gari (roasted fermented cassava grits). Cassava processors in selected parts of Ashanti and Bono East regions of Ghana were involved in the study. Focus group discussions and semi-structured questionnaires were employed for data collection. Results show that the main technological interventions used by small-scale processors in gari production are the grating machine and screw press. It was, however, noted that other key areas that require interventions are peeling and roasting. All the processors interviewed use manual means for cassava peeling and it was identified as the operation that requires the highest number of persons (15-18 people), to peel about 5-6 tonnes of cassava using about 6-9 hours. The process of manual peeling was identified as the main source of postharvest loss during small-scale processing of gari, resulting in about 13.90 (±1.26) % loss of fresh cassava which can produce about 178 kg of gari (from 5-6 tonnes of cassava). An effective mechanical peeler is therefore identified as key to facilitate gari processing in terms of operation speed and eliminating the over-dependence on manual labour. Other important developed interventions like mechanical roasters and improved stoves are also recommended to enhance gari processing. Outcome from this study is useful to researchers, investors, processors, policy makers and other stakeholders on the specific aspects of the gari processing to focus on in terms of research and investment.

Published: September 2022

Collard (Brassica oleracea var.acephala L.) is a nutritious leafy vegetable that is widely cultivated and consumed in Kenya. However, collard is highly perishable with a shelf life of one to two days at ambient conditions, which limits its consumption. Exploring storage options and packaging methods that can extend the shelf life of collards, can avert quantity and quality losses of the vegetable. This will ensure sustained income to producers and continued vegetable supply to consumers. The study aimed to evaluate the effectiveness of CoolBotTM Technology and Modified Atmosphere Packaging (MAP) as options to preserve quality and extend the shelf life of collards. Two experiments were conducted at Kabete and Juja sub-counties using freshly harvested collards from the University of Nairobi Kabete farm. In each experiment, homogenous batch of freshly harvested collards were first divided into four batches. The vegetable batches were then subjected to two storage options (CoolBotTM cold room; 5±2 °C, 75±20% RH, and ambient conditions; 25±10 °C, 50±15% RH), which were further split into two packaging treatments (packaged using Xtend® MAP, and unpackaged). The experimental layout was a 2 by 2 factorial arranged in a completely randomized design with three replications. Measurements were performed daily to determine cumulative weight loss, yellowing, wilting and color changes. Biochemical assay was also performed to determine the changes in vitamin C and beta-carotene content. Results show that CoolBotTM cold storage extended the shelf life of collards by 6 days without MAP and 13 days with MAP, in comparison to collards stored at ambient conditions. The slow rate of deterioration under CoolBotTM storage (with or without MAP) was evidenced by delayed yellowing, wilting, and reduced weight loss compared to ambient conditions, in the two experimental sites. The loss in vitamin C content was significantly higher (p ≤ 0.05) in collards under ambient conditions than those under CoolBotTM storage. In ambient conditions, unpackaged collards lost 77.7% of their vitamin C content while the packaged collards lost 57.7% by end of shelf life (day four). In CoolBotTM storage, packaged collards lost 18.4% whereas the unpackaged lost 26.3% of their initial vitamin C content. In CoolBotTM storage, packaged collards lost 26.2% while the unpackaged lost 44.1% of their initial Vitamin C by day seven. These results demonstrate a synergistic effect of CoolBotTM cold storage and MAP in preserving quality and extending the shelf life of collards.

Published: September 2022

Although there are diverse kinds of leafy vegetables in Nigeria, fluted pumpkin is one of the most consumed. However, the high perishability of its leaves has been a source of concern, of which mild processing has been suggested in the literature as a way out. Several studies have been done on the production and profitability of fluted pumpkins. However, none exist on consumers' willingness to pay (WTP) for processed fluted pumpkins based on sensory/organoleptic attributes in Nigeria. This study, therefore, fills this gap by investigating consumers' perception of processed fluted pumpkin leaves, their WTP for processed fluted pumpkin leaves and the amount they are willing to pay, and the factors affecting their WTP. Data used in the study were obtained using a set of pretested structured questionnaires in an interview schedule, and it was administered to 120 consumers in Ilorin, North-central Nigeria. Descriptive statistics and logistic regression analysis were used to analyse the data. The logistics regression checked the factors affecting the WTP for the processed leaves. The study found evidence that consumers have a high perception of the sensory/organoleptic attributes – general acceptability, texture, colour, general appearance, and aroma - of the processed fluted pumpkin leaves; with 92.3% of them willing to pay for the processed fluted pumpkin leaves while 34.2% of the consumers were willing to pay a premium which was more than the conventional price of fresh fluted pumpkin leaves. The study also revealed that the perception of consumers about the sensory attributes of the processed pumpkins and their preferences for the processed leaves positively influence their willingness to pay. This shows that there could be a market for this product. Based on the study's findings, it is therefore recommended that further studies be carried out on processed fluted pumpkins to ascertain their suitability for scaling their production for the market.

Background: In the era of precision agriculture, application of fertilizer based on soil testing is an essential tool to prescribe nutrient doses for crops to improve nutrient use efficiency and yield of hybrid castor. Methods: Field experiment was conducted in 2021 at the Tapioca and Castor Research station, Yethapur, region near Salem city, Tamil Nadu, India (11o35’N, 78o29’E). By adopting inductive cum targeted yield model fertilizer prescription equation (FPEs) were developed for hybrid castor under irrigated condition for Alfisol soil order. Initially soil fertility gradient were established with respect to soil available N, P and K nutrients and twenty four treatment were imposed in three fertility strips under factorial randomized design. The basic parameters [nutrient requirement (NR) and nutrients contributions from soil (Cs), fertilizer (Cf) and farmyard manure (Co)] were calculated from the field experimental data. Result: The nutrient required for producing one quintal of hybrid castor seed yield was evaluated as 3.20 kg of nitrogen, 1.23 kg of phosphorus pentoxide (P2O5) and 3.28 kg of potassium oxide (K2O). The study revealed that soil nutrient contribution was high in case of available phosphorus (41.87%), available nitrogen (21.56%) and available potassium (19.12%) respectively toward P, N and K nutrient uptake by hybrid castor. The nutrient contribution from farmyard manure (Co) towards the total uptake was 21.40% of N, 10.35% of P2O5 and 26.06% of K2O respectively. Using basic data, FPEs were developed for hybrid castor and ready reckoner were developed for operational range of soil test values for desired yield target under NPK alone and IPNS (NPK and FYM).

Authors: Gipal Robert John D. , Carrillo Leonard John , Mallonga Jose Carlos
Published: September 2022

The outbreak of the COVID-19 pandemic has profoundly altered the conventional face-to-face to a new modality of teaching and learning, all across the globe. Several changes have occurred as the pandemic ran its course and became a challenge for the majority of teachers. In this regard, this study aimed to explore teachers’ experiences of online teaching in English as a Second Language (ESL) classes during the COVID-19 pandemic. The findings of the study indicated that although others were getting accustomed to the use of technology in the teaching–learning process, the majority of language teachers expressed that online teaching has several limitations, such as access to the Internet and ownership of technological devices, classroom management in terms of low students’ participation and teachers’ readiness to facilitate online teaching, which might affect their experience in teaching ESL online. Hence, the researchers recommend that as the present situation continues to challenge the quality of education during these trying times, educators should have additional training in technology and should be given enough resources and support to ensure positive outcomes for the students.

Pathways to Impact in the Pandemic
Authors: Taylor Joe , Quak Evert-jan , Georgalakis James , Clark Louise
Published: September 2022

Implementing and ascertaining impact and outcomes of research is a prolonged process that may take several years due to complexities in bureaucratic, social, and economic systems. At the macro level, collective reflection on the different methods and approaches that research projects use to promote uptake and impact is rare but has potential to encourage learning and exchanges between different funders and projects around impact pathways as useful road maps for research. The Covid-19 pandemic has changed the nature of research – while it has increased the demand for evidence to inform decision-making, it has further disrupted both the policy-influencing and engagement activities that would usually accompany such research. This report is based on an analysis of 90 research projects supported by the Covid Collective, COVID CIRCLE, and Covid Response for Equity (CORE) initiatives. It provides an overview and insight into how different funders and initiatives were working to facilitate change in the context of the Covid-19 pandemic. In line with the Economic and Social Research Council (ESRC) definitions of ‘impact’, and subsequent work by the ESRC-FCDO’s (Foreign, Commonwealth & Development Office) Impact Initiative, four categories were used to map the emerging outcomes and different types of change. These outcome areas comprise capacity, networks, conceptual, and instrumental outcomes. Outcome examples were then classified into more detailed descriptive groups highlighted in Table 1.

Aim: To examine the diagnostic performance of virtual touch tissue quantification (VTQ) mode of Acoustic Radiation Force Impulse (ARFI) elastography imaging in differentiating benign and malignant thyroid nodules.

Materials and Methods: Two hundred four solid and mostly solid nodules >5mm were prospectively evaluated with ultrasonography, VTQ mode of ARFI elastography, fine needle aspiration biopsy, and when indicated with tissue pathology. Three shear-wave velocities (SWV) measurements were done in 196 nodules. The SWV ratio for each nodule was calculated as the mean value of the SWV of the nodule divided by the mean value of the adjacent parenchyma. The diagnostic performance of SWV value and SWV-ratio were assessed by a receiver-operating characteristic (ROC) curve analysis.

Results: The mean SWV value in the normal parenchyma, in benign and malign thyroid nodules, were 2.13±0.44 m/s, 2.06±0.80 m/s, and 2.06±0.88 m/s respectively. The SWV-ratios were 0.97±0.37 for benign thyroid nodules and 1.02±0.40 for malignant thyroid nodules. There was no significant difference between benign and malign nodules in terms of mean SWV values (t=0.008) (P=0.994) or SWV-ratios (t =0.596; P=0.527). No cut-off point was found to predict malignancy. In subgroup analysis, AUCs for the SWV and SWV-ratio were significantly different between nodules ˂10 mm and those ≥10 mm, but not with any other two groups (all P>0.05) (Table-2). The cutoff points for the differential diagnosis were 2.59 m/s for SWV and 1.0 for SWV- ratio respectively for nodules
Pattern making and pattern breaking

How do new ideas emerge in academic contexts and what forces determine which ideas get selected and which are forgotten? We analyze all papers presented at the ANPEC Brazilian Economics National Meetings from 2013 to 2019 using topic modeling and Kullback-Leibler divergence to measure novelty and resonance. In contrast to simply counting citations or reference combinations, these methods explore the Shannon information in the actual texts to detect the rise of new patterns and whether these patterns persist once they have been established. We find that novelty is highly correlated with transience so that most new ideas are quickly forgotten. However, of the ideas that persist, those that are more novel have higher impact. We show that our text-based measure of impact is correlated with subsequent citations.

This study is a phenomenological study on the meaning of life pursued by middle-aged menand women after retirement. The purpose of this study is to contribute to spending the life afterretirement in a more meaningful way by finding the meaning of life pursued by middle-agedmen and women after retirement through phenomenological research methods. Individualin-depth interviews were conducted with five middle-aged men and women to analyze themeaning of life pursued after retirement phenomenologically. The main results of the researchwere categorized into economic stability, social adaptation, psychological adaptation, andself-realization. Middle-aged men and women who are about to retire viewed adapting tosociety through social bonds, service, and talent donation based on economic stability as animportant factor. In this process, it was recognized that the psychological adaptation stage ofsimplifying life with psychological leeway is very important. Most importantly, retirement is nolonger a time to finish and organize one’s life, but a time of redesign, as well as a process ofself-realization to find what one really wants through hobbies. In addition, in the process ofpreparing for retirement, individual retirees should plan and prepare on their own, but policies,social efforts, and support is also required to meet the needs of retirees.
A crisis like no other: Disruptions of the Covid-19 pandemic in the neoliberal African higher education era
Authors: Ndofirepi A. , Hungwe J. P.
Published: September 2022

The Covid-19 pandemic has offered an opportune moment to assess the neoliberal tendencies in (South) African higher education. In critiquing neoliberal tendencies in higher education, this article proffers the thesis that university in (South) Africa perpetuates and entrenches neoliberalism as a Eurocentric canon, thereby shadowing the public good agenda of higher institutions of learning. The dawn of democracy in many African countries ushered in new thinking concerning higher education policy and practice. However, the Covid-19 pandemic has exposed the fact that African higher education has remained tethered to the former colonial powers’ whims, thereby maintaining the dominator-dominated relationship. We argue that the imposed Western-style education has produced an educated élite with Western values and entrepreneurial attitudes that pilot their states on the path to modernity through the capitalisation of knowledge. Subsequently, the Covid-19 pandemic has exposed deep inequalities in relation to access to African higher education. To that end, we conceptualise the predominance of neoliberal philosophy in African higher education as an instrument of keeping the public good idea of the African universities under surveillance. We provide theoretical evidence of how African universities are still suffering from colonisation of the mind decades after the attainment of political independence through complicit or sometimes implicit imbibing and embracing of the Euro-centred neoliberal philosophy under the guise of globalisation. We make a case for (South) African higher education to turn the tide to encompass locally relevant teaching and research with an eye on local needs in the context of Covid-19 pandemic. On the understanding that Covid-19 pandemic affected places differently, we argue that the deep underlying inequalities in African higher education were exposed.
Pedagogies of access and success among South African university students in the extended curriculum programmes amidst COVID-19 disruptions
Authors: Nyoni P.
Published: September 2022

The shift from contact to online classes as universities sought to ensure continuity in its academic enterprise not only happened within a context of uncertainties, hesitancy, and contestations but it had huge implications on pedagogic access and educational success for students from disadvantaged academic and social backgrounds. This article uses an ethnographic approach that draws from a combination of personal interactions with 24 participants who included 12 extended students, 4 parents, 4 academic and 4 administrative staff drawn from two South African universities, one of them in an urban and the other in a rural setting. Two key objectives feature in the article, that is how students in the extended curriculum programme have experienced online pedagogies and with what effects on their academic access and success. The article’s key findings highlight how through inclusive pedagogies with a holistic focus, the influences of societal and university ethos together with teacher competencies and other features become central when exploring pedagogic access and access nuances that confront students particularly the extended students within a setting featuring disruptions resulting from the COVID-19 pandemic. The article further makes a case for the relevant pedagogies that can be adopted for dealing with student success issues especially under periods of disruptions. The article further highlights ways in which the move to online pedagogies has not just threatened the success of these students but the very foundations of the extended curriculum programme which aims at addressing issues of student exclusion and success. The article concludes that while the experiences of the extended students represent a microcosm of the broader challenges faced by university students in general, there is evidence that successful inclusive models are those that are holistic with a focus on addressing diverse issues associated with university teaching and learning especially when untested online pedagogies are adopted.
Neonatal Intra-Ventricular-Hemorrhage Prevention in Premature at < 30 Weeks Gestational Age. A 12 years experience
Authors: Hoyos Angela , Vasquez-Hoyos Pablo
Published: September 2022

Introduction: Intraventricular Hemorrhage (IVH) is a devastating condition mostly in preterm infants at < 30 weeks GA with large morbidities and mortality usually in the first 72 hours after birth. Prevention seems to be the only way to completely deal with this problem. The IVH prevention in this age group has been studied and includes some strategies such as prenatal corticosteroids, cesarean delivery, careful extraction among others, but still, it has an unacceptably high incidence in this population. A protocol with the name Drive to Zero IVH Prevention Project that was presented in one of EpicLatino conferences some years ago. As with any quality improvement in practices, we adapted this project to our unit. Objective: To compare the IVH incidence in our unit after the protocol implementation with and historic cohort from the same unit and with all other units un the epilactino network. Material and method: In October 2017 we begun to implement a neuro protection protocol. For this analysis we include every patient born <30 weeks of GA, inborn or outborn but less than 2 days old, that survived at least three days and had a neuroimaging preformed. We include cases until July 2022, and we use the EpicLatino, a Latin-American database, from 2018 to 2020 excluding our own unit for comparison as well as an historical cohort from our unit from 2010-2017. The protocol consists of: Minimal manipulation, low volume ventilation, one routine fiscal exam a day, neutral head position, one blood pressure measured per shift, no keel stick measurements, continuous dim light and low noise level, minimal touch, no vasoactive therapy except in extreme cases, temperature and humidity at 80%, catheters, when possible, fluid restriction followed with diuresis, no PDA therapy or Echo if possible and routine therapy with hydrocortisone, erythropoietin, caffeine, parenteral nutrition, and trophic feeding. e performed a univariate analysis for IVH and groups and a logistic regression model with variables that had statistical significance in the univariate analysis. Results: The study group included 64 cases, the historic cohort 123 and the EpicLatino 1029. Demographic characteristics were similar with few statistically significant differences. We found four grade 1-2 and six grade 3-4 IVH in the study group (some caused by very traumatic delivery with multiples hematomas in head, body, and extremities), all significantly lower that the other two groups. The logistic regression model confirmed the independent statistically significant result in the study group. Conclusion: The hemorrhage during delivery must be prevented by the obstetric team. Afterwards, a set of interventions like very gentle handling with minimal manipulation and unnecessary strict lab managing seams to decrease the incidence of IVH.

Background: The thoracolumbar fascia (TLF) is thought to play a role in the development of LBP, but it is not yet clear which factor of TLF changes is a cause and which is an effect. Therefore, some studies used the cross-correlation function (CCR) to reveal time-dependent relationships between biomechanical and neuromotor factors. Methods: Ten patients with acute low back pain (aLBP) were matched to healthy controls. Simultaneous recording of surface electromyography (sEMG) of the erector spinae muscle (ES) and dynamic ultrasound (US) images of TLF deformation were performed during trunk extension. CCR functions and Granger causality were used to describe the relationship between the two measures. Results: CCR time lags were significant higher in the aLBP group (p = 0.04). Granger causality (GC) showed a direct effect of TLF deformation on ES activation only in the aLBP group (p < 0.03). Conclusions: The results suggest that in aLBP, ES activity is significantly affected by TLF, whereas this relation-ship is completely random in healthy subjects studied with CCR and GC comparisons of dynamic US imaging and sEMG data signals. Fascia-related disturbances in neuromotor control, particularly due to altered muscle spindle functions, are suspected as a possible mechanism behind this.

This study aimed to evaluate the role of chest radiographs and electrocardiograms in predicting the hemodynamics of congenital heart disease (CHD). This retrospective study included 50 patients with a diagnosis of CHD who had undergone any form of cardiac intervention, either surgical or nonsurgical between September 2019 and September 2020. Chest radiographs and electrocardiograms were evaluated and compared with the diagnostic gold standard echocardiography. Chest radiographs had the highest sensitivity, specificity, and accuracy, with all being 100%, in detecting situs and cardiac position. There was a very good agreement between chest radiographs and echocardiography in the detection of both situs and cardiac position (κ = 1.00, p < 0.001), while moderate agreement was observed for the detection of cardiomegaly, position of aortic knuckle, main pulmonary artery dilation, and right pulmonary artery dilation. Electrocardiograms had a high sensitivity (100.00%), but modest specificity and accuracy for the detection of left ventricle pressure overload. For the detection of left atrial enlargement and left ventricle volume overload, electrocardiograms had high specificity (94.12% and 94.29%, respectively) but low sensitivity and modest accuracy. There was a moderate agreement between electrocardiograms and echocardiography in the detection of right ventricle pressure overload (κ = 0.43, p = 0.002) and left ventricle volume overload (κ = 0.46, p < 0.001). The study findings indicate that chest radiographs and electrocardiograms alone are not adequate for the assessment of hemodynamics of CHD and reinstates the recommendation that in addition to routine chest radiographs and electrocardiograms, echocardiography should be performed.
Separable States on Density Matrices and Emergent Systems
Authors: Navarrete Yasmin , Davis Sergio
Published: September 2022

In this paper, we propose a quantitative definition of emergence from the density matrix framework as a state of knowledge of the system and its generalized probability formulation, in order to detect emergent properties. We propose the use of a descriptor based on the difference of von Neumann entropy, to calculate if subsystems of systems have inner correlations by defining emergent systems in terms of emergent information.

A method is developed to identify molecular scaffolds potentially active against the Mycobacterium tuberculosis complex (MTBC). A structurally heterogeneous set of compounds active against MTBC was used to obtain a structural pattern model based on structural invariants. This model was statistically validated through a Leave-n-Out test. It successfully discriminated between active or inactive compounds over 86% in database sets and was also able to select new active chemical structures in external databases. The selection of new substituted pyrimidines, pyrimidones and triazolo[1,5-a]pyrimidines was particularly interesting because these structures could provide new scaffolds in this field. The seven selected candidates were synthesized and six of them showed activity in vitro.

In recent years, the demand for coffee has increased tremendously. During the production process, green coffee beans are traditionally screened manually for defective beans before they are packed into coffee bean packages; however, this method is not only time-consuming but also increases the rate of human error due to fatigue. Therefore, this paper proposed a lightweight deep convolutional neural network (LDCNN) for the quality detection system of green coffee beans, which combined depthwise separable convolution (DSC), squeeze-and-excite block (SE block), skip block, and other frameworks. To avoid the influence of low parameters of the lightweight model caused by the model training process, rectified Adam (RA), lookahead (LA), and gradient centralization (GC) were included to improve efficiency; the model was also put into the embedded system. Finally, the local interpretable model-agnostic explanations (LIME) model was employed to explain the predictions of the model. The experimental results indicated that the accuracy rate of the model could reach up to 98.38% and the F1 score could be as high as 98.24% when detecting the quality of green coffee beans. Hence, it can obtain higher accuracy, lower computing time, and lower parameters. Moreover, the interpretable model verified that the lightweight model in this work is reliable, providing the basis for screening personnel to understand the judgment through its interpretability, thereby improving the classification and prediction of the model.
Surface Engineering of Nanomaterials: Processing and Applications
Authors: Saha Mainak
Published: September 2022

At present, nanomaterials (NMs) show extreme potential for a wide range of applications ranging from aerospace to energy storage applications owing to a number of properties which, in a number of contexts have been reported to be superior as compared to those of bulk counterparts. However, the high surface area to volume ratio which yields extraordinary properties to NMs also turns out to be the major limitation in a number of different contexts. For instance, the high surface area to volume ratio in these materials leads to a high reactivity, especially in electrochemical environments which are prevalent during energy storage applications. In this context, it is worthwhile mentioning that processing of NMs play a crucial role in influencing their mechanical properties. On the other hand, surface engineering has emerged as a powerful tool to deconvolute bulk properties from surface characteristics and has been reported to exhibit tremendous potential for overcoming the aforementioned limitation of NMs. The present review therefore, is aimed at highlighting the present status of research in the field of processing and applications of surface engineered NMs. Moreover, challenges and future perspectives in the aforementioned avenue have been discussed.
