Phytochemical content and antioxidant activity of Komba-komba (Eupatorium odoratum L)

Komba-komba (Eupatorium odoratum L) is a shrub, which is native to America. Traditionally, komba-komba is used to treat burns, wounds, skin infections, postpartum wounds, malaria, coughs and colds, and has anti-gonorrhoea, anti-inflammatory, anthelmintic, analgesic and antioxidant properties. This study aimed to investigate the phytochemicals from Komba-komba roots and in vitro antioxidant activity. Komba-komba root powder was macerated using methanol as solvent. Then fractionated with n-hexane, chloroform, and ethyl acetate. The antioxidant power was measured using the DPPH radical inhibition method and reducing agents using the FRAP method. Komba-komba root exhibited the strongest antioxidant activity. The ethyl acetate fraction showed the strongest antioxidant activity using both the DPPH method and the FRAP method with IC50 values, 10.0598±0.0665 g/mL, and 16.4782±0.3558 g/mL, respectively. The antioxidant activity of komba-komba root was correlated with its phenolic and flavonoid content. Komba-komba root showed very high phenolic and flavonoid contents to be developed as a source of natural antioxidants.
Inside the black box : an exploration of change mechanisms in drug and alcohol rehabilitation projects

This research addresses the question ‘How does transformative change occur in rehabilitation programmes, and how is it facilitated or constrained by contextual factors? ’ The study, carried out in three community-based intensive rehabilitation projects for alcohol and drug dependent people, is designed to specify and explain change mechanisms, understood as the processes through which programme resources influence the intentional actions of participants. A critical realist theoretical frame is used, drawing on the work of Margaret Archer and John Greenwood. The study consisted of two phases: in Phase 1, fourteen client interviews and eight counsellor interviews were carried out in two treatment programmes, and these were analysed abductively to produce a set of tentative contexts, mechanisms and outcomes. Phase 2 consisted of ten theory-driven interviews (Pawson 1996) with clients in a third programme, designed to elaborate the emerging theory. An explanatory model was produced, in contexts-mechanisms-outcomes form. This showed that the institutional context of active warmth and acceptance, combined with a clear, predictable and transparent structure, allowed participants to build trust, bond with the peer group and become ready to accept and process respectful challenges to their perspective or their interpersonal behaviour. This facilitated a change in the clients’ internal conversation (Archer 2000), permitting new emotional responses and the formation of new attachments, values and commitments. The programme was seen as a place which facilitated the development of a revised personal and social identity. The study contributes to the understanding of these programmes by clarifying how participants change or fail to change. It responds to recent calls for more useful forms of evidence, to complement the sparse and equivocal experimental evidence base. The study findings have the potential to improve counsellor training and programme development.
Women on Boards: Does Corporate Culture Influence Board Gender Diversity?

We examine the link between corporate culture and the company’s willingness to appoint women to the Boards of Directors. We proxy corporate culture by how companies communicate with investors in the 10-K filings. Our findings provide persistent evidence for a causal link between competitive and collaborative corporate culture and board gender balance. Companies characterized by a high degree of competing culture tend to appoint fewer female directors, consistent with the stylized fact that women shy away from competition. Companies with a high degree of collaborative culture appoint on average more women to their Boards. Companies that score high on collaborative culture, care about achieving goals as a team and long-term human development are likely to be genuinely interested in appointing female directors because they oftentimes have more than one woman on the Board. We also show that, in line with tokenism theory, companies characterized by a less collaborative (more competitive) culture are more likely to appoint female directors only to ‘tick-the-box’ rather than to truly benefit from board gender diversity. We use a dynamic approach to address the reverse causality issue and show that female directors have the potential to affect corporate culture only when they constitute a critical mass in the board.
Phylogenetic Analysis and Flower Color Evolution of the Subfamily Linoideae (Linaceae)

The taxonomy of the subfamily Linoideae at the intergeneric and section levels has been questioned throughout the years, and the evolution of floral characters remains poorly understood. In particular, the evolution of flower color is still uncertain, despite its ecological importance and being one of the most variable and striking traits in Angiospermae. We evaluated the phylogenetic relationships of the genera and sections and used the phylogeny to reconstruct the ancestral state of flower color. The results suggest reevaluating the taxonomic status of segregated genera and re-incorporating them into Linum. Four of the five sections currently accepted were recovered as monophyletic (Cathartolinum, Dasylinum, Linum, and Syllinum). We propose accepting the section Stellerolinon and reevaluating Linopsis, whose representatives were recovered in three separate clades. The ancestral flower color for Linoideae was yellow-white. The flower colors purple and yellow-white were recovered at the deepest nodes of the two main clades. Pink, blue, and red colors were the most recent to evolve. These results appear to be related to diversification events, biogeographical history, and ecological aspects of the subfamily. Our reconstruction constitutes the first plausible scenario that explores the evolution of flower color, leading to new testable hypotheses for future research on the flax group.
The Guadalupian conodont fauna of Rustaq and Wadi Wasit, Oman and a West Texas connection

The red, ammonoid-bearing limestones at Rustaq and Wadi Wasit contain Jinogondolella aserrata, the index species for the type Wordian. It occurs with an abundant smooth Mesogondolella fauna and an advanced Waagenoceras ammonoid fauna. In the rustaq section, two species of Mesogondolella are present in both lower and upper red, ammonoid-bearing limestones with M. siciliensis dominating the lower beds and M. omanensis (new species) dominating the upper beds. The same two Mesogondolella species occur in the single, ammonoid-bearing limestone unit at the Wadi Wasit section, where there are additional conodont species including M. bitteri. The faunas at Wadi Wasit section and the upper red, ammonoid-bearing limestone at the Rustaq section contain Stepanovites? festivus which is indicative of the Wordian-Capitanian boundary interval. Capitanian Jinogondolella altudaensis appears in the rocks above the ammonoid-bearing limestone at the Wadi Wasit section.
Are You Getting Likes as Anticipated? Untangling the Relationship between Received Likes, Social Support from Friends, and Mental Health via Expectancy Violation Theory

ABSTRACT There is a pressing need to understand whether using social media might be linked to mental health and if yes, how. The findings of this study (N = 475) show that individuals who received more Likes on social media posts reported more friend support. However, what matters to mental health is the level of expectancy violation of the number of received Likes. The two dimensions of expectancy violation of receiving Likes (number vs. responder) have different effects on the outcome variables. Theoretical and practical implications about how social media influences friend support and mental health for young adults are discussed.
Normative behaviour-based first-best analysis for disaster evacuation

ABSTRACT The most uncertain aspect in designing an evacuation plan is the evacuation behaviours of individuals in the immediate aftermath of a natural disaster. Hence, this study attempts to reduce behavioural uncertainty and proposes a first-best analysis assuming that all evacuees perfectly follow the best evacuation strategy that is termed as normative behaviour. Although the first-best performance may not be practical or feasible, it clearly shows the benchmark performance of evacuation planning. This type of a benchmark is quite useful to understand the relative performances of several more practical scenarios. The results indicate that the first-best strategy is obtained by solving a Linear Programming in a time-dependent manner. Additionally, a practical solution algorithm is proposed based on the Lagrangian relaxation method. The method is then applied to the city of Ishinomaki, Japan, to confirm its computational feasibility.
Potential Role of Certain Biomarkers Such as Vitamin B12, ROS, Albumin, as Early Predictors for Prognosis of COVID-19 Outcomes

COVID-19 disease is still a major global concern because of its morbidity and its mortality in severe disease. Certain biomarkers including Reactive Oxygen Species (ROS), vitamins, and trace elements are known to play a crucial role in the pathophysiology of the disease. The aim of our study was to evaluate how certain biomarkers, such as ROS, biochemical indicators, trace elements in serum blood of 139 COVID-19 hospitalized patients, and 60 non-COVID cases according to age and sex variations, can serve as the predictors for prognosis of COVID-19 outcome. An attempt of correlating these biomarkers with the severity of the disease as well as with each other is represented. All subjects were hospitalized from April 2021 until June 2021. A statistically significant increase of B12 levels (p = 0.0029) and ROS levels (p < 0.0001) as well as a decrease in albumin and Total Protein (T.P.) levels (p < 0.001) was observed especially in the early stage of the disease before CRP and ferritin elevation. Additionally, a statistically significant increase in ferritin (p = 0.007), B12 (p = 0.035, sALT p = 0.069, Glucose p = 0.012 and urea p = 0.096 and a decrease in Ca p = 0.005, T.P p = 0.052 albumin p = 0.046 between stage B (CRP values 6–30 mg/L) and C (CRP values 30–100 mg/L) was evident. Thus, this study concludes that clinicians could successfully employ biomarkers such as vitamin B12, ROS and albumin as possible prognosis tools for an early diagnosis. In addition, the total biochemical profile can assist in the understanding of the severity of COVID-19 disease, and could potentially lead to a better diet or early pharmaceutical treatment to prevent some of the more acute symptoms.
Underwater acoustics propagation analysis and modelling of sound emitting devices

Electro-Mechanical devices such as Wave Energy Converters (WECs) are potentially an important technology for the generation of renewable ocean energy. These underwater Acoustic Emitting (AE) machines are liable to experience certain failure modes such as damaged bearings, hydraulic faults, electrical arcs, vibration, etc. during their operation. This can lead to catastrophic failure of components of an overall ocean based system if necessary preventative measures are not taken. It is important therefore to create a robust condition monitoring process of rapid detection and classification of faults in these machines, to reduce costs and increase lifetime and reliability. This will assist companies involved in the deployment of these systems, particularly companies involved in the renewable ocean energy and marine technology sectors, to improve on the operational and management costs of ocean based systems, specifically impacting on efficiency and yield, reliability, and maintenance costs. Underwater sound around AE machines and vessels is often monitored for environmental impact assessment studies, and could be used to monitor the health of AE machines and vessels. This thesis illustrates the acquisition and visualization of acoustic signals produced by underwater AE machinery/vessels. It illustrates the technique involved in the deployment of an acquisition system and the subsequent conditioning, processing and presentation of the acquired underwater acoustic data. The work presented in this thesis also involves numerical modelling and simulation of low frequency component sound signals of underwater AE machines and vessels. It illustrates the effect of the interaction of sound signals with varied surfaces and boundaries, and their influences on the propagation of these underwater sound signals. A brief study of the effect of acoustic signals on marine fauna is also discussed in this thesis.
The Latest Data Specifically Focused on Long-Term Oncologic Prognostication for Very Old Adults with Acute Vulnerable Localized Prostate Cancer: A Nationwide Cohort Study

Purpose: Few studies have evaluated the prime treatment choice for men older than 80 years with acute vulnerable localized prostate cancer (AV-LPC). Clinicians have been deeply troubled by this near end-of-life medical choice for a very specific group of patients. We compared the oncological prognostication of very old patients with AV-LPC after they underwent either radical prostatectomy (RP) or massive-dose intensity-modulated radiotherapy (IMRT) coupled with long-term androgen deprivation therapy (ADT) over a long-term investigation. Methods: In this nationwide cohort study, we used the Taiwan Cancer Registry Database and retrieved information related to patients (aged ≥ 80 years) with AV-LPC who underwent standard RP (the RP group) or massive-dose IMRT + long-term ADT (at least 72 Gy and ADT use ≥18 months; the IMRT + ADT group). After potential confounders were controlled for using propensity score matching (PSM), we utilized the Cox proportional hazards regression to evaluate the oncologic prognostication. Results: The IMRT + ADT group had a significantly higher adjusted hazard ratio (aHR) for all-cause mortality (aHR, 2.00; 95% confidence interval [CI], 1.41–2.87) than the RP group. Analysis of the secondary outcomes revealed that compared with the RP group, the aHRs of biochemical failure, locoregional recurrence, and distant metastasis in the IMRT + ADT group were 1.77 (95% CI: 1.36–2.11, p < 0.0001), 1.12 (95% CI: 1.04–1.33, p < 0.0001), and 1.15 (95% CI: 1.06–1.71, p = 0.0311), respectively. Conclusion: RP provides more favorable oncological prognostication than IMRT in very old adults with AV-LPC.
KNOWLEDGE, ATTITUDES AND BEHAVIORS OF VIETNAMESE PEOPLE ABOUT SINGLE-USE PLASTIC PRODUCTS AND HEALTH IMPACTS IN 2021

The study was conducted to assess the knowledge, attitudes and behaviors of using single-use plastic products and the impacts on health. The results showed that the proportion of people with full knowledge of the effects of single-use plastic use on cardiovascular, reproductive health, nervous system and other organs was 57,5%; 63,4%; 55,8% and 50,3%, respectively. 98,5% of respondents were willing to replace single-use plastic products with environmentally friendly products. 48% and 51,2% of respondents regularly and occasionally use plastic products. The results of the study also show that people do not have access to information about the effects of single-use plastic products on health. It is necessary to promote communication activities on the impact of single-use plastic products on health and promulgate policies to limit and replace single-use plastic products.
Projects, Agency and the Multi-Level Perspective

This paper discusses the role of projects in technological transitions. Based on a case study of a technological transition in numerical weather prediction the paper discusses the multi-level perspective (MLP) framework developed by F. Geels & al. (2002 & next). This framework has been criticized for its macro-level perspective and its difficulty to deal with the question of agency. Our research suggests that the project level constitutes a promising avenue to discuss this question in the multi-level perspectives framework. It demonstrates how, in this case, a project play a major role in the transition from one technological regime to another and how at the project level actors can be included more precisely in the MLP. In so doing it also propose a type of transition not envisioned by the MLP research. Finally we suggest that bridging MLP and project management research, particularly contemporary works on innovative projects, could be fruitful for both fields.
Organic Enrichment Induces Shifts in the Trophic Position of Infauna in a Subtropical Benthic Food Web, Hong Kong

Anthropogenic nutrient input to coastal waters is one of the most common disturbances within inshore marine benthic communities. Organic enrichment in sediments leads to the reduction or disappearance of sensitive organisms, and influences the quality and quantity of primary producers which serve as food sources for the benthic fauna. Such changes, in turn, affect the energy flow and food-web interactions in benthic communities. To examine how organic enrichment may alter marine benthic trophic relationship, a stable isotope (δ13C and δ15N) analysis of the potential food sources and a range of meiofauna and polychaetes from an organically polluted and a relatively unpolluted site was compared in subtropical waters of Hong Kong. Results indicated that some omnivorous infauna shifted from a mainly carnivorous diet at the unpolluted site to a largely herbivorous diet at the organically polluted site. This dietary shift is likely to be related to the oxygen stress, prey limitation and increased abundance and nutritional quality of primary producers in the eutrophic area, resulting in an increase in utilization of plant materials as the major food source. The present findings suggest that such changes in trophic position induced by organic enrichment can provide further insights into the structure and function of coastal benthic communities under pollution stress.
The WHATs and HOWs of maturing computational and software engineering skills in Russian higher education institutions

ABSTRACT Russian higher education institutions' tradition of teaching large-enrolled classes is impairing student striving for individual prominence, one-upmanship, and hopes for originality. Intending to converting these drawbacks into benefits, a Project-Centred Education Model (PCEM) has been introduced to deliver Computational Mathematics and Information Science courses. The model combines a Frontal Competitive Approach and a Project-Driven Learning (PDL) framework. The PDL framework has been developed by stating and solving three design problems: (i) enhance the diversity of project assignments on specific computation methods algorithmic approaches, (ii) balance similarity and dissimilarity of the project assignments, and (iii) develop a software assessment tool suitable for evaluating the technological maturity of students' project deliverables and thus reducing instructor's workload and possible overlook. The positive experience accumulated over 15 years shows that implementing the PCEM keeps students motivated to strive for success in rising to higher levels of their computational and software engineering skills.

Affective Antidepressant, Cytotoxic Activities, and Characterization of Phyto-Assisted Zinc Oxide Nanoparticles Synthesized Using Sanvitalia procumbens Aqueous Extract

Green synthesis of nanoparticles has emerged as an effective and environmentally friendly method. Therefore, the current investigation is based on the green synthesis of zinc oxide nanoparticles (ZnO-NPs) using plant extract of Sanvitalia procumbens (S. procumbens) that act as a capping and reducing agent. S. procumbens is a fast-growing shrub and densely available plant and may have potential to synthesize ZnO-NPs. The synthesized ZnO-NPs were characterized by different techniques, including Fourier transform infrared spectroscopy (FT-IR), UV-visible (UV-Vis), energy-dispersive X-ray (EDX), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The UV-Vis spectrum at 350 nm revealed an absorption peak for the synthesis of ZnO-NPs. In addition, photoactive biomolecules of the prepared ZnO-NPs were identified by using FT-IR spectroscopy. Furthermore, the spherical geometry of ZnO-NPs was evaluated by SEM images. The synthesized ZnO-NPs were also used to enhance the antidepressant activity and exhibited a remarkable reduction in the time of immobility in tail suspension tests (TST) and forced swim tests (FST), as well as increased the BDNF levels in the brain and plasma. ZnO-NPs have a low risk of biocompatibility (cell visibility) at a concentration of 7 g/mL or below. The nanoparticles were biologically compatible when the concentrations were increased up to 11 μg/mL. It was concluded that ZnO-NPs were investigated as a possible carrier for antidepressant drug delivery into the brain, and their excellent cytotoxic activity was evaluated by using the MTT assay to determine their biocompatibility.
