Plant Bioestimulants: Compost Tea and Bioslurry Characterization

In the present study, the quality of aerated and non-aerated compost teas and bioslurry as bio-fertilizers and its application on two plant species in different substrates were tested. Compost tea brewed from a mixture residues compost presented higher nutrient content than that brewed from grape marc composted. Aeration, with shorter extraction time, resulted in higher pH, but in general with lower nutrient concentration, while bioslurry, presented higher nitrogen content. No pathogen and toxic effects were detected in the bio-products. Finally, Bio-products were evaluated in ornamental plant species: Petunia hibrida and Impatiens walleriana , where compost teas and bioslurry presented highly variable properties and effects on plant growth, depending on the substrate and species used. While in sand no significant effect on plant biomass and pigments were observed, in compost and commercial substrate bioslurry presented values similar to the traditional fertilizer. Compost tea presented variable results with no differences between aerated and non-aerated, both increasing carotenoids in I. walleriana in sand. We conclude that aeration showed no differences in compost tea quality, whilst bioslurry demonstrated to increase plant biomass at similar values to traditional fertilizer. Our results demonstrated that alternative products are an efficient, safe, ecological, and economical alternative to traditional products.
Role of insulin, insulin sensitivity, and abomasal functions monitors in evaluation of the therapeutic regimen in ketotic dairy cattle using combination therapy with referring to milk yield rates

Background: Ketosis is one of the most critical metabolic disorders that occur in dairy cows after parturition due to negative energy balance around calving. Aim: The study evaluated a specific therapeutic regimen of ketosis in Holstein dairy cattle by using the combination therapy including hormones, corticosteroids, propylene glycol, and vitamin B12 as well as the use of milk yield rates, insulin, insulin sensitivity, and abomasal functions monitors as diagnostic biomarkers for the recovery of ketotic cows either pre-therapy (0 days) or post-therapy (7 and 14 days). Methods: This study was conducted on ketotic cattle (n = 20) belonged to different dairy farms in Cairo and Giza governorates, Egypt. The diseased cows were undergoing clinical and biochemical investigations for the estimation of serum insulin. Quantitative Insulin Sensitivity Check Index (RQUICKI) and abomasal functions monitor mainly serum levels of gastrin, pepsinogen, and chloride. Results: The milk production rates, cost: benefit analysis ratio, and benefit of the dairy farm in ketotic animals were significantly increased post-treatment. An improvement of insulin sensitivity was stated as serum insulin, and RQUICKI were remarkably increased in post-therapeutic ketotic cows. Monitors of the abomasal function revealed abomasal functions improvement through the significant elevation of blood gastrin and a substantial reduction in serum pepsinogen due to treatment. Conclusion: The study revealed high efficacy of the applied therapeutic strategy regime. It led to a high recovery rate and a very low relapse rate for ketosis. An improvement in milk yield rates, insulin sensitivity, and abomasal function monitors was reported. Hypoinsulinaemia was still reported, however, serum insulin was improved.
Perception of residents and workers toward the environmental health effects of the dumpsite in Solous Igando, Lagos, Nigeria

Dumpsites are an ideal breeding ground for disease vectors such as rats and mosquitoes. Which may channel severe health issues to the nearby residents and dumpsite workers on the dumpsite. The present study aimed to assess the effects of waste disposal at a dumpsite on the surrounding human settlements and health of the workers. In this descriptive study, data were collected from the households within the 0-3 kilometer radius to the dumpsite as well as the dumpsite workers using structured questionnaires. In total, 150 respondents from the human settlements around the dumpsite participated in the study including 61 dumpsite workers. Test of independence indicated a significant correlation between the perception of the dumpsite workers and community dwellers towards the dumpsite as a source of health deteriorating agents, (χ2 [1; n = 211] = 14.00; p=0.001). Dumpsite odor, insect and rodent infestation and burning activities could predict the ill health status of the dumpsite workers with the final predictive model Ill health status = 0.439 + [0.645*Odor of dumpsite] + [0.106*Insect and Rodent infestation] + [-0.151*Burning activities on the dumpsite]; F[3,57]= 21.70; p
Effect of COVID-19 Pandemic on Physical Activity Habits, Musculoskeletal Pain, and Mood of Healthcare Workers

Objectives: Self-isolation seems to be the best way to slow down the coronavirus disease 2019 (COVID-19) outbreak, but it may also have negative impact on physical and mental health. The aim of this study was to investigate the changes in physical activity habits during the outbreak and also the impact of the pandemic on musculoskeletal pain and mood in correlation with physical activity in healthcare workers. Methods: This study is conducted through Google Forms web survey platform. A total of 310 hospital staffs completed the Google Forms questionnaire in 2 weeks during lockdown and curfew period in Istanbul. The questionnaire included 60 questions including demographic, occupational, COVID-19 exposure data, physical activity habits, musculoskeletal pain, and mood. Results: There was a significant difference between physical activity habits before and after the pandemic (p<0.001). Individuals engaged in regular physical activity (regardless of duration) had significantly higher happiness ratings (p=0.002). No statistically significant difference was found between the duration of physical activity and the musculoskeletal pain during the pandemic. Conclusion: Pandemic caused a decrease in physical activity, an unhappy and anxious mood, and an increase in musculoskeletal pain of healthcare workers. Participants who were doing regular physical activity were less unhappy, but no relationship between exercise and musculoskeletal pain was found which might be related to psychosocial state of the participants who worked under great stress with high effort during the pandemic.
Real-world treatment patterns and outcomes in small-cell lung cancer: a systematic literature review

Background Small-cell lung cancer (SCLC) accounts for 12–15% of lung cancers and is associated with poor survival outcomes and high symptom burden. This study employed a broad, systematic search strategy and timeframe to identify evidence on real-world treatment patterns and outcomes for SCLC outside the USA, including understanding sub-populations such as extensive-stage (ES) or limited-stage (LS) disease. Methods Databases (MEDLINE, Embase, and EBM reviews) were searched for journal articles published in the English language between 1 January 2000–1 March 2020 and supplemented by hand searching of conference abstracts and posters presented at conferences between 1 January 2016–1 March 2020 reporting real-world treatment outcomes in patients with SCLC. A targeted clinical guideline review was also completed. Results One-hundred studies provided quantitative data; 57 were available as full-text articles, whilst the remaining 43 were presented as abstracts or posters. The majority (80 studies, 80%) of included studies reported treatment in the first-line setting, where platinum-based chemotherapy and chemoradiotherapy was the most commonly used treatment strategy, in line with current treatment guidelines in SCLC. First-line treatments were found to have a high response rate; however, most patients relapsed early. No studies reported treatment or outcomes with immune-oncology therapies. Second-line treatment options were very limited, and primarily consisted of either re-treatment with first-line regimen or topotecan, but the prognosis for these patients remained poor. Outcomes were particularly poor amongst those with ES or relapsed disease vs. LS disease. Conclusions SCLC treatment patterns and short survival outcomes have remained constant over the previous 20 years. Due to the search timeframe, none of the studies identified reported on the impact of recently approved immune-oncology therapies in SCLC. Further data is needed on the impact of immunotherapies on treatment patterns and real-world outcomes in SCLC.
Energy-Efficient Power Allocation and Splitting for mmWave Beamspace MIMO-NOMA With SWIPT

Non-orthogonal multiple access (NOMA) has recently been employed into millimeter wave (mmWave) beamspace MIMO to further improve connection density and spectrum efficiency for the emerging cellular internet of things (IoT) with massive IoT sensors and devices. Meanwhile, to achieve energy-efficient green communication, an advanced energy harvesting technique named simultaneous wireless information and power transfer (SWIPT) has been regarded as a promising solution. In this paper, we study the integration of SWIPT in mmWave beamspace MIMO-NOMA system. To improve the energy efficiency while guaranteeing the minimum rate and harvested energy requirements at each IoT node, we analyse the energy efficiency maximization via power allocation at the base station and power splitting at each IoT node. The challenge is that this joint optimization problem is non-convex and intractable due to the presence of intra-beam and inter-beam interference. To tackle it, we propose a two-layer iterative algorithm by leveraging Dinkelbach method and alternating optimization (AO) framework. Specifically, the original fractional objective function is transformed to an equivalent subtractive one via Dinkelbach method at the outer layer, whereas in the inner layer, AO is adopted to address the transformed optimization problem. Numerical results indicate that: 1) the proposed joint power allocation and splitting algorithm can converge within five iterations; 2) the proposed scheme can achieve higher energy efficiency and achievable sum rate compared with the existing scheme and conventional beamspace MIMO with SWIPT.
Improvement of Hardness of Hydroxyapatite by the Addition of Silica from Tin Tailings

The application of bone scaffolding in bone therapy is an alternative solution developed in bone tissue engineering technology to avoid bone donors' scarcity. The main requirement for a material that can be used as a scaffold is that it is biocompatible. Hydroxyapatite is a calcium phosphate ceramic that is often used as the primary material for scaffolding because it has good biocompatibility properties. However, like most ceramics, hydroxyapatite has low mechanical properties. In this study, we synthesized hydroxyapatite from cockleshell waste. To improve hydroxyapatite's mechanical properties (hardness), we added silica from tin tailings to hydroxyapatite. Through the analysis of the x-ray diffraction (XRD) pattern, it was found that hydroxyapatite was successfully synthesized from cockleshell using the co-precipitation method. Analysis of the diffraction pattern of tin tailings also shows that most of the crystals comprising tin tailings sand are silica in the ? -quartz phase. The addition of silica to hydroxyapatite followed by compaction and sintering at a temperature of 800 ? did not produce a new crystal phase. The addition still has a diffraction pattern consisting of a combined XRD pattern of hydroxyapatite and silica. Based on the hardness test using the Vickers hardness method, it is known that the addition of silica can increase the hardness of hydroxyapatite.
Paradigm shift in the concept of corporate social responsibility: COVID-19

The purpose of the paper is to analyse the development of the concept of corporate social responsibility (CSR) between two the most drastic crisis periods that have shaken the world society, i.e., the Great Depression and the COVID-19 pandemic. The concept of CSR has expanded from its perception as philanthropic actions to the systematic corporate activities and intensive interaction with stakeholders based on social, economic, and environmental interests aimed at long-term sustainable economic development and public welfare. With the rapid spread of the COVID-19 around the world, the companies have faced the challenge of moving to a new environment. Our findings suggest that CSR activities are implemented by the companies around the world as a response to the COVID-19, regardless of the country’s level of development. The companies with many years of CSR experience act responsibly towards their communities and society. The concept of CSR is still evolving, but the main goal remains the same at any stage of development—to contribute to public safety and well-being. The results show that the companies, analysed in the paper, contribute to the implementation of CSR goals through socially responsible activities even in the crisis period.

TRIBUTE TO FOUNDERS : ROGER SARGENT . PROCESS SYSTEMS ENGINEERING TeCSMART : A Hierarchical Framework for Modeling and Analyzing Systemic Risk in Sociotechnical Systems

Recent systemic failures in different domains continue to remind us of the fragility of complex sociotechnical systems. Although these failures occurred in different domains, there are common failure mechanisms that often underlie such events. Hence, it is important to study these disasters from a unifying systems engineering perspective so that one can understand the commonalities as well as the differences to prevent or mitigate future events. A new conceptual framework that systematically identifies the failure mechanisms in a sociotechnical system, across different domains is proposed. Our analysis includes multiple levels of a system, both social and technical, and identifies the potential failure modes of equipment, humans, policies, and institutions. With the aid of three major recent disasters, how this framework could help us compare systemic failures in different domains and identify the common failure mechanisms at all levels of the system is demonstrated.

Cellulose/boron nitride core–shell microbeads providing high thermal conductivity for thermally conductive composite sheets

We fabricated sheets with high thermal conductivity in a way that required less filler. Our approach is as follows: (1) we used core–shell spherical microbeads as the thermally conductive filler; (2) we developed cellulose/h-boron nitride (BN) core–shell spherical microbeads using phase separation of a cellulose xanthate aqueous solution (viscose); (3) we hybridized the cellulose/h-BN core–shell microbeads with epoxy resin using compression molding. This process reduced the amount of h-BN required because the microbeads efficiently formed thermally conductive pathways among the shells in the insulating resin. The thermal conductivities of the resulting sheet in the thickness and in-plane directions were 10.6 and 15.6 W m−1 K−1, respectively, using only 48.5 vol% h-BN. In contrast, the thermal conductivities of the composite sheet with 75 vol% of naked h-BN particles were 6.31 and 22.9 W m−1 K−1 in the thickness and in-plane directions, respectively. This large difference resulted from the anisotropic structure of h-BN. The changes in thermal conductivity with h-BN content were inconsistent with percolation theory, when using the cellulose/h-BN core–shell microbeads as a filler. The thermally conductive sheets fabricated with microbeads exhibited thermal conductivities several times greater than that of sheets fabricated with naked h-BN. This indicated that thermally conductive pathways had formed in the insulating resin.
DNA barcoding approach to characterize microalgae isolated from freshwater systems in Ecuador

ABSTRACT The use of suitable DNA barcodes and the generation of databases with reference sequences have been considered a promissory approach for the identification of Chlorophyta and Cyanophyta microalgae. In this study, we carried out a molecular characterization and identification of strains isolated from freshwater systems in Ecuador using a dual barcode method. The target sequences for Chlorophyta were 18S rDNA and rbcL genes, and 16S rDNA and 16S–23S rDNA intergenic spacer (ITS) for Cyanophyta. We reported these DNA barcodes for 20 different Molecular Operational Taxonomic Units (MOTUs) for Chlorophyta and 10 for Cyanophyta. Our results show that the 18S V4 hypervariable region (300 bp) is sufficient for differentiating between isolates, but rbcL is a determinant for genus identification in Scenedesmaceae and Chlorellaceae strains. In Cyanophyta, both barcodes enabled the genus-level assignment of 9 out of 10 MOTUs. These results highlight the necessity of a second barcode additional to small ribosomal subunit sequences to improve molecular identification. Furthermore, the present study significantly contributes to the body of Ecuadorian barcode sequences of microalgae that are currently documented, making them available for future comparative diversity studies.
Musculoskeletal injuries in basketball players Southern Portugal: Epidemiology and risk factors

Objective: Basketball consists of a contact sport that involved actions such as running, jumps, and abrupt changes in direction several times and these repetitive movements can lead to injuries. The objective of this study was to verify the epidemiology of musculoskeletal injuries and risk factors in basketball players. Methods: The sample comprises 361 basketball athletes Southern Portugal, being 238 (65.9%) males, aged between 10 and 53-years-old. The instrument used for data collection was a questionnaire with questions about the population characterization and related to the basketball practice and injuries. Results: Two hundred and thirty-nine (66.2%) players referred an injury throughout their practice, totaling 494 injuries, and 174 (48.2%) players reported an injury in the previous year, with a total of 244 injuries. There were 2.72 injuries/1,000 h of basketball training. The most common injuries were sprain (43.8%), the most injured body area was the ankle (40.1%) and the principal injury mechanism was the impact with another athlete (19.4%). The basketball players who trained more than 4 times a week showed a 2.21 greater chance to develop injury (95% CI: 1.3–3.5; p=0.003) than those who trained less often. Conclusion: This study showed a high prevalence of injuries in this analyzed sample, being the ankle and knee the most injured body areas, the sprain the more prevalent type of injury, and the impact with another player the main mechanism of injury. The data obtained can be used to create training programs with the objective of preventing injuries on basketball players.
A study of direct injection diesel engine fueled with hydrogen

In this study, characteristics of the development and auto-ignition/combustion of hydrogen jets were investigated in a constant-volume vessel. The authors focused on the effects of the jet developing process and thermodynamic states of the ambient gas on auto-ignition delays of hydrogen jets. The results show that the ambient gas temperature and nozzle-hole diameter are significantly effective parameters. By contrast, it is clarified that the ambient gas oxygen concentration has a weak effect on the auto-ignition/combustion of hydrogen jets. Consequently, it is supposed that the mixture formation process is capable of improving the autoignition/combustion of hydrogen jets.
Impact of external and internal factors on successful grafting of Pinus pseudostrobus var. oaxacana (Mirov) Harrison

Introduction: Grafting allows full multiplication of phenotypic and genotypic characteristics of genetically improved trees. Objective: To determine the influence of bud origin, rootstock fertilization, grafting period and grafting techniques on the success of grafting, growth, and survival of intraspecific grafts in Pinus pseudostrobus var. oaxacana (Mirov) Harrison. Materials and methods: The effect of four factors was evaluated ([a] two bud sources, [b] three rootstock fertilization doses, [c] three grafting seasons and [d] two grafting techniques) on the success of grafting, shoot growth (Sg) and survival. An analysis of variance was carried out to determine the effect of factors a, b, c, and d on successful grafting and Sg, and a Log-Rank test was carried out for survival analysis. Results and discussion: Significant differences (P ≤ 0.05) were obtained for factors a, c and d. Grafting during winter (December 2018 and February 2019) using the side-veneer grafts technique and buds coming from Santa Catarina Ixtepeji showed the highest values of successful grafting (≥25.5 %), Sg (≥14.5 cm) and survival (≥20.5 %). Final survival decreased from 100 to 27 % 90 days after grafting. Conclusions: Grafting period, bud origin, and grafting technique, individually or interacting with, are determinant factors for the success of intraspecific grafting on P. pseudostrobus var. oaxacana
