Isolation and Characterization of Cellulose Nanofibrils from Banana Pseudostem, Oil Palm Trunk, and Kenaf Bast Fibers Using Chemicals and High-intensity Ultrasonication

ABSTRACT The adoption of high-intensity ultrasonication in the isolation process of cellulose nanofibrils (CNF) as an economical, timesaving, and environmental-friendly process has been explored. Three types of raw organic fibers, i.e., banana pseudostem, oil palm trunk, and kenaf bast were analyzed for the production of CNF using the process mentioned earlier. Before the raw organic fibers were subjected to a high-intensity ultrasonication process, it underwent an alkaline treatment to eliminate the non-cellulosic compounds. Field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM) micrographs confirmed the presence of nanofibrils in all three different types of CNF. The frequency, amplitude, and duration of ultrasonication used in this study were sufficient to produce CNF. Fourier-transform infrared spectroscopy (FTIR) results indicated that the chemical treatment employed in this paper was effective in removing the compounds, especially lignin and hemicellulose. The increase in crystallinity, which is one of the advantages of CNF, was observed from the X-ray diffraction (XRD) results. Hence, it can be deduced that high-intensity ultrasonication could simplify the complex process of CNF isolation compared to the conventional method, widening the utilization and source of CNF in the industry.
MED29, A Subunit of the Mediator Complex, Possesses Oncogenic Characteristics in Ovarian Cancer

Background: Somatic copy number alteration (SCNA) usually accompanies the appearance of tumours; one common example is the 19q13.2 region amplification (AMP). Studies have shown that the 19q13.2 AMP might worsen the prognosis of patients with pancreatic cancer, and mediator complex subunit 29 (MED29) might be an amplified effector gene within this region. In this study, the role and molecular mechanism of MED29 in ovarian cancer (OvCa), one of the three major tumours in gynaecology, were discussed.Results: According to the transcriptome and survival data from the TCGA database, 19q13.2 AMP corresponded with a worse prognosis of OvCa patients (P = 0.0253), and individuals with 19q13.2 AMP showed increased levels of MED29 mRNA. From the GSE29450 dataset, we found that the gene expression of MED29 was significantly upregulated in OvCa and overexpression of MED29 in OvCa was related to shorter survival. Additionally, pathway analysis based on RNA-seq data indicated that MED29 could activate the expression of genes involved in cell proliferation. Moreover, knockdown of MED29 obvious inhibited the proliferation, invasion and migration of OVCAR3 and A2780 cells and arrested the cell cycle at the G2/M transition in vitro.Conclusion: MED29 could be used as a potential therapeutic target for OvCa treatment.
EMPIRICAL EVIDENCE ON SYSTEM IMPLEMENTATION FAILURES IN THE ENTERPRISE RESOURCE PLANNING DEVELOPMENT PROCESS

Enterprise resource planning (ERP) relates primarily to software for business management, which consists of many modules that are essential for the growth and survival of various types of companies and organisations. By allowing faster supply chain management, the incorporation of similar business applications in an organisation will bring considerable advantages to the organisation. In order to increase business efficiency, ERP implementation helps businesses to adapt and customise information flows and automate business processes. The implementation of the system was reviewed with sufficient literature to substantially support the significance of arithmetic and logical principles and basic programming errors, including programme typographical errors, syntax error detection, and programme output process errors. Furthermore, the declaration of variables, the significance of modularisation and the need to support accessories, the accessibility of library files and the importance of frameworks have been discussed. In order to recognise framework implementation deficiencies in the ERP development process, improvement of coding formatting and significance of coding syntax were also critically checked with appropriate literature.

Striving for Improvement: The Perceived Value of Improving Hurricane Forecast Accuracy

Hurricanes are the costliest type of natural disaster in the United States. Every year, these natural phenomena destroy billions of dollars in physical capital, displace thousands, and greatly disrupt local economies. While this damage will never be eliminated, the number of fatalities and the cost of preparing and evacuating can be reduced through improved forecasts. This paper seeks to establish the public’s willingness to pay for further improvement of hurricane forecasts by integrating atmospheric modeling and a double-bounded dichotomous choice method in a large-scale contingent valuation experiment. Using an interactive survey, we focus on areas affected by hurricanes in 2018 to elicit residents’ willingness to pay for improvements along storm track, wind speed, and precipitation forecasts. Our results indicate improvements in wind speed forecast are valued the most, followed by storm track and precipitation, and that maintaining the current annual rate of error reduction for another decade is worth between $90.25 and $121.86 per person in vulnerable areas. Our study focuses on areas recently hit by hurricanes in the United States, but the implications of our results can be extended to areas vulnerable to tropical cyclones globally. In a world where the intensity of hurricanes is expected to increase and research funds are limited, these results can inform relevant agencies regarding the effectiveness of different private and public adaptive actions, as well as the value of publicly funded hurricane research programs.
The Research of the Development Process of Equity Incentive in China

The equity incentive system originates from western developed market economy countries. In the past few decades, the development of the equity incentive system has been ignored at the beginning and then widely concerned. Since China's reform and opening up, it has gradually explored the implementation of equity incentive system in China's listed companies, among which the equity incentive system for senior managers has widely existed. This paper first discusses the important cause of the equity incentive system: the agency problem. Then it describes the development process and types of equity incentive system in China and analyzes the obstacles and challenges in the development of the equity incentive system in China. Moreover, this paper pointed out some situations of equity incentive implementation where need to improve.
The effect of uneven terrain conditions during shod vs. barefoot running

Background: The majority of research on barefoot running focuses on acute changes in altering footwear without regard to the runner’s experience with barefoot or minimalist footwear running. Objective: The objective of this study was to compare the effect of footwear (standard cushioned running shoes, barefoot) and running surface (flat surface, uneven terrain) on gait in experienced runners using minimalist shoes. Methods: Terrain running was simulated by three custom-made mats with randomly placed firmly attached stones. Seven experienced trail runners participated in this study. All participants were forefoot strikers. Participants underwent three-dimensional kinematic and kinetic analysis consisting of five running trials in each combination of footwear and surface. A trial was successful when the participant maintained a velocity of 3.2 ± 0.16 m/s without targeting a force platform. Results: Uneven terrain conditions along with barefoot conditions led to significantly decreased peak moment of ankle plantarflexion (terrain: p = .041, footwear: p = .026) and decreased second peak of vertical ground reaction force in comparison with other conditions (terrain: p = .026, footwear: p = .004). Uneven terrain conditions also significantly decreased ankle dorsiflexion at initial contact with the ground for both footwear conditions (p = .021). Conclusions: We conjecture that net ankle moments could be decreased by barefoot running in terrain conditions in skilled forefoot runners. Experienced runners using minimalist shoes may incorporate trail running into their barefoot running regime without risk of higher Achilles tendon loading compared to even running.
Earth-Abundant Electrocatalysts for Water Splitting: Current and Future Directions

Of all the available resources given to mankind, the sunlight is perhaps the most abundant renewable energy resource, providing more than enough energy on earth to satisfy all the needs of humanity for several hundred years. Therefore, it is transient and sporadic that poses issues with how the energy can be harvested and processed when the sun does not shine. Scientists assume that electro/photoelectrochemical devices used for water splitting into hydrogen and oxygen may have one solution to solve this hindrance. Water electrolysis-generated hydrogen is an optimal energy carrier to store these forms of energy on scalable levels because the energy density is high, and no air pollution or toxic gas is released into the environment after combustion. However, in order to adopt these devices for readily use, they have to be low-cost for manufacturing and operation. It is thus crucial to develop electrocatalysts for water splitting based on low-cost and land-rich elements. In this review, I will summarize current advances in the synthesis of low-cost earth-abundant electrocatalysts for overall water splitting, with a particular focus on how to be linked with photoelectrocatalytic water splitting devices. The major obstacles that persist in designing these devices. The potential future developments in the production of efficient electrocatalysts for water electrolysis are also described.
Production systems and methods affect the quality and the quantity of saffron (Crocus sativus L.)

Aim of study: Comparison of saffron flowering between open field and controlled environment. Possibility of saffron transplanting.Area of study: University of Birjand (Iran)Material and methods: In a first experiment, saffron yield and quality produced by traditional production system (TPS) and by soilless one (SPS) were compared. In a second experiment, the effects of the production method, by direct planting (DP) or by transplanting plant (TP) in open field were studied.Main results: Percentage of flowering corms grown by SPS was 39% and 65%, while by TPS was 6% and 56% in 2018 and 2019, respectively. Flower and stigma yields were significantly higher by SPS than by TPS. Stigma obtained from SPS had higher L (lightness) and crocin. Safranal content was higher in stigma produced by TPS. Leaf and root numbers and corm weight were higher for SPS, but after transplanting there was better status for DP than for TP. At the end of the first growing season (2018-19), mean replacement corms weight (4.4 vs 3.0 g), replacement corms yield (21.3 vs 12.8 g per plant), weight of main replacement corm (11.7 vs 6.0 g) and number of large replacement corms (0.6 vs 0.1 corms per plant) for DP were significantly higher than for TP. However, during the second growing season (2019-20), the plants in TP plots improved their performances.Research highlights: Saffron production was more favorable under controlled environment. Transplanting is possible, but there is a need to improve methods to gain more favorable results.
Tool Health Monitoring Using Airborne Acoustic Emission and Convolutional Neural Networks: A Deep Learning Approach

Tool health monitoring (THM) is in great focus nowadays from the perspective of predictive maintenance. It prevents the increased downtime due to breakdown maintenance, resulting in reduced production cost. The paper provides a novel approach to monitoring the tool health of a computer numeric control (CNC) machine for a turning process using airborne acoustic emission (AE) and convolutional neural networks (CNN). Three different work-pieces of aluminum, mild steel, and Teflon are used in experimentation to classify the health of carbide and high-speed steel (HSS) tools into three categories of new, average (used), and worn-out tool. Acoustic signals from the machining process are used to produce time–frequency spectrograms and then fed to a tri-layered CNN architecture that has been carefully crafted for high accuracies and faster trainings. Different sizes and numbers of convolutional filters, in different combinations, are used for multiple trainings to compare the classification accuracy. A CNN architecture with four filters, each of size 5 × 5, gives best results for all cases with a classification average accuracy of 99.2%. The proposed approach provides promising results for tool health monitoring of a turning process using airborne acoustic emission.
Continuing Professional Development: Perspectives of Kenyan Nurses and Midwives

Background: The purpose of this paper is to report the perceptions of continuous professional development by the nurses and midwives in a low resource country. These findings are part of a larger study on the experiences of nurses and midwives providing postpartum care in rural areas of Kenya. Besides being the main healthcare providers in rural areas, nurses in low resource countries have limited access to continuous professional development. Research design: This is a qualitative research guided by critical theory and Foucault’s concepts of power and knowledge. Focused ethnography provided the framework of data collection and analysis. 23 in-depth interviews were contacted, and thematic analysis was used for data analysis. Reflexive memos kept throughout the research process helped to ensure the trustworthiness of data. Findings: This paper will focus on the theme of continuing professional development (CPD) as a resource for a healthy work environment. While the knowledge of the nurses and midwives allowed them to provide care to the mothers and their infants adequately, personal and structural barriers prevented them from participating in continuing professional development. Discussion and Conclusion: A well-prepared nursing and midwifery workforce could have the capacity to transform the health outcomes of their clients through the application of evidence-based practices. Therefore, courses that are context-appropriate and meet the needs of different learners should be available to support the nurses’ and midwives’ professional growth. There is a need for more research on the nurses’ and midwives’ participation in CPD in Kenya, and the effect of CPD on specific health outcomes.
“It’s a sea-change”: Understanding the role the racial and socio-political climate play on the role-shift of the American college presidency

This inquiry is part of a larger study focused on whether white male presidents in higher education can respond to racism. In the initial study, the author concluded that while presidents were responsive, their responses were not void of privilege, and highlighted the need to further address white Fragility amongst this group. In an effort to advance our understanding of the American college presidency, particularly how the racial and socio-political climate has shaped their leadership, in the current study, the author analyzed data using the perspective offered by the presidents – higher education is in a sea-change, which was also a finding, as well as specific facets of Astin and Astin’ (2000) and Buller’s (2015) respective frames of change. The analysis yielded the Education Policy Analysis Archives Vol. 29 No. 40 SPECIAL ISSUE 2 importance of naming that higher education is in a sea-change, grappled with the reality of power within the presidency, and articulated the value of being willing over being ready to incite change. In light of these findings, these leaders recognized that not only is higher education due for a change, but so is the postsecondary presidency. Such an understanding expands both the organizational leadership and diversity in higher education literature, respectively.
Iminopyridine Ni(II) Catalysts Affording Oily Hyperbranched Oligoethylenes and/or Crystalline Polyethylenes Depending on the Reaction Conditions: Possible Role of In Situ Catalyst Structure Modifications

Nickel-based ethylene polymerization catalysts have unique features, being able to produce macromolecules with a variable content of branches, resulting in polymers ranging from semicrystalline plastics to elastomers to hyperbranched amorphous waxes and oils. In addition to Brookhart's -diimine catalysts, iminopyridine Ni(II) complexes are among the most investigated systems. We report that Ni(II) complexes bearing aryliminopyridine ligands with bulky substituents both at the imino moiety and in the 6-position of pyridine afford either hyperbranched low molecular weight polyethylene oils or prevailingly linear crystalline polyethylenes or both depending on the ligand structure and the reaction conditions. The formation of multiple active species in situ is suggested by analysis of the post-polymerization catalyst residues, showing the partial reduction of the imino function. Some related arylaminopyridine Ni(II) complexes were also synthesized and tested, showing a peculiar behavior, i.e. the number of branches of the produced polyethylenes increases while ethylene pressure increases.
Effects of Soil Water Deficit on Three Tree Species of the Arid Environment: Variations in Growth, Physiology, and Antioxidant Enzyme Activities

Low water availability predicted under climate change is a major abiotic factor limiting plants growth and productivity. In this study a greenhouse experiment was conducted on three important tree species of arid environment: Conocarpus erectus (CE), Acacia modesta (AM), and Salix tetrasperma (ST). Young saplings were subjected to control (C), medium (MWD) and severe soil water deficit (SWD) treatments and response was evaluated. Results showed that in all the three species leaf, stem and root dry weight production remained similar to C under MWD treatment but decreased significantly under SWD. The highest decrease in total dry weight was noticed in ST and the lowest was evidenced in AM under SWD. Root:shoot ratio increased significantly in both CE and AM under MWD and SWD. Furthermore, chlorophyll content decreased while proline content increased significantly in both MWD and SWD treatments. The production of oxidants (hydrogen peroxide and superoxide anions) and antioxidants (superoxide dismutase, catalase, peroxidase and ascorbate peroxidase) increased significantly under both MWD and SWD treatments and were the highest in AM in both MWD and SWD treatments. Therefore, we may conclude that all the three species can tolerate medium water stress due to increased root production and an effective antioxidant defense mechanism.
Snout shape and masticatory apparatus of the rodent‐like mesotheriid ungulates (Notoungulata, Typotheria): exploring evolutionary trends in dietary strategies through ancestral reconstructions

Mesotheriidae were small to medium‐sized native South American ungulates. Mesotheriids radiated from the early Oligocene epoch to the early–middle Pleistocene, in two subfamilies: Trachytheriinae and Mesotheriinae. Beyond the conspicuous fossil record, little is known about mesotheriid palaeobiology, and particularly, the dietary habits. To date, different studies suggest grazing habits, similar to some extant ungulates, but recent contributions are challenging this vision. Here, we explore dietary preferences in mesotheriids, focusing on food intake and oral processing strategies. We performed a shape analysis of the snout and reconstructed ancestral shapes to assess evolutionary trends within the clade. Also, we considered other morphological variables of the masticatory apparatus to perform a functional characterization. We recognized three snout configurations: Trachytherus, ‘Intermediate’ and Mesotherium morphotypes that can be associated with different food intake capabilities and, considering other morphological proxies, with the consumption of different food items. Taking into account palaeoenvironmental conditions, the evolution of the masticatory apparatus is interpreted in the context of a consumption gradient from coarse and tough foods (roots, tubers, tough leaves) to grasses. We propose that during the ecomorphological evolution of mesotheriids, an initial phase took place during the late Oligocene and Miocene, consisting of diversification and specialization for consumption of hard‐to‐break food items. A second phase began incipiently during the late Miocene, and became well‐defined during the Pliocene and Pleistocene, characterized by an ecomorphological displacement towards grazing habits. Inferred dietary habits in Mesotheriidae could provide light on palaeoecological evolution and niche partitioning within South American herbivorous mammalian communities.
