Building a culture of innovation in learning and teaching technologies through an innovators group

Innovation was seen as crucial for universities even before the COVID-19 global pandemic, to widen participation within massification strategies, to deliver graduates that meet the needs of economies and to justify increased fees in response to reduced government funding. Innovation will become increasingly important as universities contribute to the post-pandemic recovery of their communities and nations and need to find new avenues for research funding with less reliance on governments. In this paper, we describe our first steps towards developing a culture of innovation in learning and teaching across science, health, and engineering disciplines by bringing together and empowering a group of mostly junior academics. We describe achievements of this group, indicate key success factors, and discuss next steps.
OPTIMIZATION OF CONVENTIONAL AGRICULTURE (TILLAGE X FERTILIZATION X PLANT PROTECTION) FOR SOYBEAN IN THE TRANSYLVANIAN PLAIN

"The purpose of this study was to improve conventional agricultural technologies in soybean crop to ensure a higher yield and reduced environmental impact under climate conditions specific for the Transylvanian Plain. For the experimental design a three-factorial experiment was set up (tillage x fertilization x plant protection products). Factor interaction was evaluated using formula AxBxC-R:4x4x4-3 to highlight the benefits of the practices. This study examined yield crops and size of the soybean plants in an effort to identify best practices. Yield was highly increased in conventional soil tillage system (3420 kg/ha), whereas for the minimum soil tillage system and for direct sowing there were no significant difference 2755-2995 kg/ha and 2605 kg/ha, respectively. Crop performance in terms of yield was highly influenced by the soil tillage system (57.5%), followed by plant protection treatments (22.9%) and fertilization (11.8%). Fertilization with N40P40 + gulle + green fertilizer ensured the highest soybean production (3132 kg/ha). Plant protection treatments during vegetation determined significant yield increases, with high influence of insecticides and a cummulative effect when both fungicides and insecticides were used (3193 kg/ha). Highest size of plants was registered in conventional soil tillage system. Overall crop protection treatments during vegetation (insecticide + fungicide) triggered not significant increases in plant size, except Teo TD soybean cultivar. "
Immunotherapy in non-small cell lung cancer: rationale, recent advances and future perspectives

Abstract Lung cancer, with non-small cell lung cancer (NSCLC) being the major type, is the second most common malignancy and the leading cause of cancer-related death globally. Immunotherapy, represented by immune checkpoint inhibitors (ICIs), has been one of the greatest advances in recent years for the treatment of solid tumors including NSCLC. However, not all NSCLC patients experience an effective response to immunotherapy with the established selection criteria of programmed death ligand 1 (PD-L1) and tumor mutational burden (TMB). Furthermore, a considerable proportion of patients experience unconventional responses, including pseudoprogression or hyperprogressive disease (HPD), immune-related toxicities, and primary or acquired resistance during the immunotherapy process. To better understand the immune response in NSCLC and provide reference for clinical decision-making, we herein review the rationale and recent advances in using immunotherapy to treat NSCLC. Moreover, we discuss the current challenges and future strategies of this approach to improve its efficacy and safety in treating NSCLC.
Effect of untreated dental caries on school performance and social life

Oral diseases are highly prevalent across the different countries globally, indicating that these conditions represent a significant challenge to the healthcare authorities. Moreover, like untreated dental caries, chronic diseases were linked with poor school performance and deteriorated quality of life. This current literature review aims to discuss the effect of untreated dental caries on school performance and social life. Our findings indicate the strong association between having untreated dental caries and reduced performance at school. We also found that these children usually suffer from deteriorated aspects of social life, being more prone to verbal bullying than other children without dental caries. Different factors were reported to affect the correlation between untreated dental caries and performance at school. For instance, socioeconomic status has a significant role in this association. Evidence also indicates the vital role of gender, family income, and parental education. These findings indicate the urgent need to draw proper interventional plans to reduce the risk of dental caries. Besides, healthcare authorities should plan for screening programs to detect children with untreated dental caries and provide adequate management of these conditions to enhance the quality of life and educational aspects. However, the findings are not consistent among the different investigations in the literature. Therefore, future studies are needed to validate the current evidence and enhance the outcomes.
Lemon Rootstock Trials in Arizona – 2002-03

In a rootstock evaluation trial planted in 1993, five rootstocks, ‘Carrizo’ citrange, Citrus macrophylla, ‘Rough Lemon’, Swingle citrumelo and Citrus volkameriana were selected for evaluation using 'Limoneira 8A Lisbon' as the scion. 1994-2006 yield and packout results indicate that trees on C. macrophylla, C. volkameriana and ‘Rough Lemon’ are superior to those on other rootstocks in both growth and yield. C. macrophylla does not consistently outperform C. volkameriana. ‘Swingle’ and Carrizo’ are performing poorly.
Concurrent global optimisation for microwave-device parameter estimation

A novel concurrent implementation of a global-optimisation algorithm is used to extract parameter values for MESFET equivalent-circuit models. The problem of the location of the global minimum of an error function is addressed by the use of an efficient stochastic global-optimisation program which does not require accurate parameter estimates and which operates on a multiprocessor array. The program has been used to estimate the parameter values of a process-based physical equivalent model of a MESFET under multibias small-signal operation. These results are compared with those derived from an electrical equivalent-circuit model.
Immunological and physiological responses related to orthodontic treatment

Orthodontic treatment is usually approached to achieve better aesthetics by influencing tooth movement in different positions within the jaw. The application of mechanical forces during the process of treatment is the main responsible for these events. Remarkable changes in the vascularity of the underlying tissues were also reported to occur secondary to applying orthodontic forces. This significantly leads to the synthesis and release of many metabolites and signaling molecules. Furthermore, it might be associated with various immunological and physiological responses that enhance or deteriorate the prognosis. Therefore, the present study reviewed the literature to identify the different immunological and physiological responses secondary to orthodontic treatment. Our findings indicate that different immune cells and immunoglobulins are usually involved in orthodontic treatment-related events. Moreover, we found that cytokines and chemokines have an important role in the post-treatment inflammatory process, leading to bone resorption or bone formation. Various cytokines were reported in this context, including TNF-α, IFN-γ, IL-13, IL-12, IL-8, IL-6, and IL-1β. The roles of these modalities have been discussed based on their effects on bone remodeling following orthodontic treatment.
Participatory processes and outcomes: the case of national irrigation system management in Bohol, Philippines

The adoption of participatory irrigation management in the Philippine national irrigation systems (NIS) began in the mid‐1980s, after positive results were observed in some participatory small‐scale communal irrigation systems. Yet, NIS performance remained generally poor. In the case of the Capayas Irrigation System – an NIS located in Bohol, Philippines – farmer participation is limited, thus sustainability is low. Limited participation is rooted in the absence of initiatives to mobilize the farmers prior to facility construction, inadequate government funds and the consequent priority bias against allocation for institutional development activities. This is also due to the absence of effective mechanisms both for ensuring sanctions against delinquent water users and for promoting incentives for participation. Mechanisms for coordination among various stakeholders are necessary in order to provide an enabling environment for irrigation. Important complementary actions include mainstreaming institutional development support, periodic monitoring and evaluation of the Irrigators' Associations (IAs), and improvements in physical structures of the secondary and tertiary facilities.

Heat unit requirement of wheat (Triticum aestivum L.) under different thermal and moisture regimes

An experiment was conducted during 2016-17 and 2017-18 at WTC, ICAR-IARI New Delhi on wheat crop sown on three dates (15th November, 30th November and 15th December) with five irrigation treatments. The results indicated that the number of days required for attaining different phenological stages decreased with delay in sowing.For all the phenological stages, crop sown on 15th November consumed higher heat units and consequently resulted in higher yield and heat use efficiency (HUE) than that of other sowing. However, higher pheno-thermal index (PTI) values were observed for the late sown crop i.e. 15th December. Further, among the irrigation treatments, five irrigations throughout the growing period showed increase in days to physiological maturity as well as heat units and HUE for grain and biological yield as compared to other treatments. Five irrigations throughout the growing period increased the grain yield by 69 per cent and biological yield by 46 per cent that that of one irrigation at CRI stage. However, there was no significant difference observed between four and five irrigations levels. The heat units or GDD had highly significant correlation with biological yield(r=0.91) as well as with the grain yield (r=0.85).
The relative impact of evolving pleiotropy and mutational correlation on trait divergence

Both pleiotropic connectivity and mutational correlations can restrict the divergence of traits under directional selection, but it is unknown which is more important in trait evolution. In order to address this question, we create a model that permits within-population variation in both pleiotropic connectivity and mutational correlation, and compare their relative importance to trait evolution. Specifically, we developed an individual-based, stochastic model where mutations can affect whether a locus affects a trait and the extent of mutational correlations in a population. We find that traits can diverge whether there is evolution in pleiotropic connectivity or mutational correlation but when both can evolve then evolution in pleiotropic connectivity is more likely to allow for divergence to occur. The most common genotype found in this case is characterized by having one locus that maintains connectivity to all traits and another that loses connectivity to the traits under stabilizing selection (subfunctionalization). This genotype is favoured because it allows the subfunctionalized locus to accumulate greater effect size alleles, contributing to increasingly divergent trait values in the traits under directional selection without changing the trait values of the other traits (genetic modularization). These results provide evidence that partial subfunctionalization of pleiotropic loci may be a common mechanism of trait divergence under regimes of corridor selection.
Women Librarians in Ghana: Their Status and Career Development

The study investigated the current status and occupational characteristics of professional women librarians in Ghana. The study also sought to establish their career advancement opportunities and to investigate factors inhibiting their career development. Another objective of the study was to find out how they were perceived by their male counterparts. Using data obtained through questionnaire, the study sought for information relating to the background of female librarians in Ghana, their work experience, status and career advancement opportunities. All the professional women librarians in Ghana were included in the survey. The population size was thirty-five. The findings reveal that women librarians in Ghana could advance to any height without discrimination. Also, they did not experience any form of discrimination from their male counterparts in terms of remuneration or career development.

Rigorous analysis of arbitrarily shaped H- and E-plane discontinuities in rectangular waveguides by a full-wave boundary contour mode-matching method

A rigorous boundary contour mode-matching (BCMM) method is presented for the efficient calculation of the modal scattering matrix of arbitrarily shaped Hand E-plane discontinuities, junctions, and/or obstacles in rectangular waveguides. For the inhomogeneous waveguide region with general contour, the field is expanded in the complete set of cylindrical wave functions. The full-wave expansion allows the immediate rigorous inclusion of cascaded structures such as combined H- and E-plane bends. The efficiency of the method is demonstrated at the rigorous design of useful waveguide components which could not be modeled by mode-matching technique so far: cylindrical post-compensated H-plane T-junction, mitered H-plane and E-plane bends of arbitrary angle, cascaded H-/E-plane bends, circular post-coupled filter, E-plane filter with rounded corners, 180/spl deg/ rat race structure, and side-coupled dual TE/sub 311//TE/sub 113/-mode filter. The theory is verified by measurements. >
Hyperaldosteronism: types, clinical characteristics, and treatment

Cases with hyperaldosteronism might be asymptomatic in many events. Therefore, the diagnosis can be missed. However, the usual presentation for many patients has been reported to be a refractory elevation in the blood pressure which might be mild to severe. Based on the type of hyperaldosteronism and the diagnosis, the treatment of these conditions should be established. Therefore, it can be concluded that the treatment is specific to the management of the underlying etiology, and managing the clinical characteristics and associated complications. This present literature review aims to provide evidence regarding the types, clinical characteristics, and treatment of aldosterone based on data from the current investigations in the literature. Different clinical phenotypes have been reported for the condition. Nevertheless, the disease can be broadly classified into primary and secondary hyperaldosteronism based on the pathophysiology and etiology of the condition. Clinical characteristics might not be diagnostic since they are very non-specific, despite being common in these patients, as hypokalemia and hypertension. Therefore, clinicians should be aware of conducting the necessary diagnostic approaches before establishing the diagnosis. Management of these patients requires the integration of different approaches, including surgical and medical treatment. Perioperative care is important because it may lead to unfavorable consequences if neglected.
The Daylight Benefit Conferred Upon Adjoining Rooms by Specular Surfaces in Top-Lit Atria

Abstract Physical models of multi-storey buildings with atria were used to examine the effect of different types and arrangements of specular surfaces upon daylight benefits in adjacent rooms. The selective use of specular surfaces within atria was found to increase daylight illuminance. The testing results indicated there is no need to add specular surfaces to the atrium parapet walls at every floor level; adding such surfaces to the top level alone confers better improvement in daylighting performance.
Performance of PM assisted synchronous reluctance motor for high efficiency and wide constant power operation

This paper examines the design and the performances of a permanent magnet assisted synchronous reluctance motor (PMASRM) for a wide constant-power operation. The effects of properly adding magnets into the rotor of a synchronous reluctance motor are examined by the several experimental results and analyses on the prototype machines. The proposed machine can offer a large constant-power speed range, high-efficiency and high-power-factor operation in comparison to the complete synchronous reluctance motor. It was shown that the problems such as the decrease of efficiency at light-loads and the uncontrolled generator mode operation, which occur in the high-speed flux-weakening operation of the conventional PM motor drives, can be eliminated in the PM assisted synchronous reluctance motor.
PZT-BASED ENERGY HARVESTERS ON PLASTIC FOIL OPTIMIZED THROUGH THEORETICAL MODELING AND FABRICATION IMPROVEMENTS

Thinned bulk-PZT cantilever-based vibration energy harvesters with a tungsten tip-mass, transferred by low-temperature lamination processes onto a plastic substrate, are presented in this paper. In order to optimize their performances, correlations between theoretical models and experimental measurements have been implemented. Both analytical and FEM simulations in COMSOL have been combined to obtain a global and complete model emulating the real system behavior. As a result, an optimized device, resonating at at 41.1 Hz and able to generate an average power of 63.7 µW and a normalized power density of 3472 µW/g 2 · cm 3 at 1 g, was obtained.
Casing Wear: The Effect of Contact Pressure

One of the major factors affecting casing wear is the magnitude of the loading between the drillstring and the casing. This study describes a new test machine and experimental procedure used to study the effect of contact loads on casing wear. The results of extensive testing show that contact pressure instead of contact load is the appropriate parameter controlling the wear rate of the casing. An experimental relationship is found between contact pressure and casing wear rate for nonhardfaced tool joints in a laboratory prepared drilling mud. Knowing this, a computer program is devised to model accumulated casing wear during drilling. This work also shows the relative effects of tool joint size and drilling penetration rate on casing wear. Additional factors such as the addition of steel wear protectors in the center of the drillpipe also are explored. Conclusions are drawn as to the limitations of simple casing wear guidelines based on maximum allowable contact load. 13 refs.
Carbon Nanotubes and Graphene Nanoribbons: Potentials for Nanoscale Electrical Interconnects

Carbon allotropes have generated much interest among different scientific communities due to their peculiar properties and potential applications in a variety of fields. Carbon nanotubes and more recently graphene have shown very interesting electrical properties along with the possibility of being grown and/or deposited at a desired location. In this Review, we will focus our attention on carbon-based nanostructures (in particular, carbon nanotubes and graphene nanoribbons) which could play an important role in the technological quest to replace copper/low-k for interconnect applications. We will provide the reader with a number of possible architectures, including single-wall as well as multi-wall carbon nanotubes, arranged in horizontal and vertical arrays, regarded as individual objects as well as bundles. Modification of their functional properties in order to fulfill interconnect applications requirements are also presented. Then, in the second part of the Review, recently discovered graphene and in particular graphene and few-graphene layers nanoribbons are introduced. Different architectures involving nanostructured carbon are presented and discussed in light of interconnect application in terms of length, chirality, edge configuration and more.
A cat with myelodysplastic syndrome by administration of the methylation inhibitor Azacytidine

A 5-year-old female cat with nonregenerative anemia and thrombocytopenia was diagnosed with myelodysplastic syndromes (MDS), since peripheral blood and bone marrow (BM) examination revealed various dysplasias and a blast ratio of 19%. Chemotherapy with azacytidine (AZA; 70–35 mg/m2, 3–5 days, three cycles) and treatment with prednisolone, antibiotics, and vitamin K2, and blood transfusion were performed. On day 106, blast cells and dysplasia had decreased in the BM, and the cat remained alive for at least 1,474 days. This report is the first on feline MDS treated with AZA, suggesting appropriate drug dosage, interval and effective combination should be investigated and the pharmacological and cell biological mechanisms needs to be elucidated in the future.
Food chain information systems in medium- and smallsized slaughterhouses of central Italy and organ and carcass condemnations: A five-year survey

The flow of information between farms and slaughterhouses about animal health, is a fundamental process for modern meat inspection. The information provided by Food Chain Information (FCI) systems in medium-small sized slaughterhouses in central Italy, focusing on the data provided on the animal’s health status, was performed through a five-year survey together with the number of organ and carcass condemnation for bovine, swine and ovine. The annual prevalence of condemnation was higher in bovine (from 10.49% in 2015 to 17.16% in 2019) than swine (from 6.39% in 2015 to 12.64% in 2019) and ovine (from 8.05% in 2019 to 8.98% in 2017), and an overall prevalence increase was observed in bovine and swine, throughout the years. The frequent lack of Food Chain Information (FCI) from farms to slaughterhouses should be emphasised, taking into consideration that a poor implementation of the system by farmers, could lead to a persistent risk of disease at farm level for these two species.
Agency and fidelity in primary teachers’ efforts to develop mathematical resilience

ABSTRACT Teaching using the principles of mathematical resilience can lead to a broad range of implementations with different emphases, all intended to mitigate the development of mathematical anxiety in learners and its attendant problems. This article considers 12 primary teachers’ responses to the challenge of developing mathematical resilience within their practice. In pairs, these teachers conducted a small-scale study in their classrooms on a chosen aspect of mathematical resilience, supported by termly meetings. The reports made by the participant teachers form the main part of the data. The teachers were inspired to change how they worked with their learners and reported many positive outcomes. The agency which some teachers exercised influenced not only their outworking of the ideas, but also the fidelity with which they adopted the principles underpinning mathematical resilience. The connections and tensions shown here between agency and fidelity have wider implications for successful implementation of similar change efforts.
