Tyrosinase is an enzyme involved in generation of dopamine-quinones, which has an important role in oxidative stress associated with the Parkinson’s disease. It is also a common molecular target for the design of novel anti-melanogenic agents. The inhibition of tyrosinase might be responsible for the experimentally observed intracellular antioxidant activity of α-arbutin. Moreover, intrinsic radical scavenging capacity of α-arbutin should also be considered. The binding mode of α-arbutin into the active site of Bacillus megaterium tyrosinase is predicted using AutoDock Vina 1.1. To map the thermodynamic feasibility of HAT and SET-PT mechanisms of the intrinsic antioxidant capacity α-arbutin, bond dissociation enthalpies (BDEs) and ionization potential (IP) are calculated using DFT with B3LYP functional and 6-31+g(d,p) basis set. α-Arbutin fitted well into the active site of tyrosinase, with the calculated binding affinity of -17.5 kcal/mol. The phenolic moiety is located deep into the binding pocket, interacting with His residues around Cu2+ ion. The binding mode of α-arbutin is stabilized via HBD interactions with His231, His42, His60, Arg209, Gly216, and Asn205, HBA interaction with Arg209 at the outer part of active site, and hydrophobic interactions with His208, Val218 and Ala221. The calculated IP of α-arbutin is 175.18 kcal/mol, and BDE of phenolic group is 79.85 kcal/mol. The spin densities of radical-cation and hydroxyl radical are delocalized on the aglycone moiety. The results of this study provide valuable structural insights into the molecular mechanisms of biological action of α-arbutin, and might be exploited for the design of more potent analogues.

The anthropogenic impact of effluents and indiscriminate use of antibiotics in aquaculture promotes the emergence and proliferation of antibiotic resistant (ABR) bacteria. Comparative total bacterial and ABR counts were determined from 3 locations of the Cadimahan river of Capiz province, Philippines. The upstream station showed lower total bacterial but higher ABR counts, which is the inverse of the downstream station which showed higher total bacterial but lower ABR counts. The ABR counts accounted for 0.0173%, 0.0043% and 0.0002% of the total bacterial counts for upstream, midstream, and downstream, respectively, showing a strong inverse correlation of -0.84 in the Pearson correlation coefficient. This result suggests a remediating effect potentially mediated by microbial dynamics in the Mangrove-riverine system.

Published: November 2021

Since the outbreak of the pandemic COVID-19, a huge amount of information has been released and shared by individuals, communities and specialized organizations. Language serves as a powerful tool on which information providers depend to convey their advice and instructions. In this study, the researchers examined the frequency of interactional metadiscourse markers in the WHO's director general's speeches regarding the COVID-19 pandemic and how those markers are used for communicative and persuasive effects. The corpus included 91 scripts with a different number of words making a total of 84,372 words. Hyland's (2005) model of metadiscourse was used to analyse the corpus. Data analysis revealed that interactional metadiscourse markers are heavily used by WHO director to deliver coherent speeches and to make his speeches persuasive. Moreover, the findings show that the speaker relied intensively on the use of self-mention marker and boosters to reflect the collaborative and assured attitude of the organization concerning the situation of the pandemic.

The purpose of this study is to evaluate the link between motivational variables, work performance, and employee engagement, as well as the influence of motivational factors on job performance via the use of employee engagement as a mediator in the Sultanate of Oman's government sector. The research used a quantitative technique and examined six hypotheses using 111 representative government workers from the Ministry of Education. This is pilot research. This research used quota sampling and analyzed data using the Statistical Package for the Social Sciences (SPSS) and path analysis approaches. The study's results suggest that these elements are associated positively, that motivational factors are associated positively with employee engagement and work performance, and that employee engagement functions as a partial mediator in the link between motivational factors and job performance. This report is crucial for public sector executives and regulators interested in improving job performance in Oman. This is one of the few research that examines employee engagement's mediating role in the relationship between motivational characteristics and work performance. This is one of the first studies of its sort for the public sector in Oman. In future studies, other motivating elements might be studied and assessed in the private sector.
When Man is a Cause: The Undecidability of Belonging in Kanafani's Returning to Haifa
Authors:   Hadhramout University, Mukalla-Hadhramout, Yemen University Sains Malaysia (USM), Penang, Malaysia, Badurais Rasha Saeed Abdullah
Published: November 2021

The focus of my article is on the undecidability of Dov's/ Khaldun's identity throughout his conversations with Said X., his 'biological father', along with some significant selective semiotic referents in Ghassan Kanafani's novella Returning to Haifa. These aspects are highlighted to elicit/ trace Kanafani's implied symbolism of Palestine, the land, and the undecidability/ conflict of its belonging to critique (healthy self-criticism) the submission of the Palestinians as being guilty of ceding with their land then keep crying to restore it. The novella has been previously tackled from a variety of perspectives: parody, intertextuality, characterization, among others. However, the key parts of the novella that show the conflict between father/ son, self/other, right/loss are the conversations between Dov/Khaldun and Said X. To achieve the article's goal, Derrida's conception of undecidability is employed to indicate the inability to take a decision due to factors beyond the focal character's, Dov/Khaldun, means. This state of freeplay makes it impossible to settle to any side/identity. In Dov's/ Khaldun's case, it is the indeterminate area between the biological Palestinian identity and the acquired Jewish identity. Given that, this view of undecidability is supplemented by other related philosophical aspects such as identity of the 'I', the conception of belonging, and the symbolic reflection between the Dov/ Khaldun: the Jew/ the Palestinian: the Colonizer/ the Colonized (both Man and the land). The analyses of the novella reveal that a state of bewilderment and vortex of undecidable identity opens once Dov Iphrat Koshin, the Israeli soldier, knows he was born Khaldun Said, the Palestinian citizen. Dov's/ Khaldun's words to Said X. show a defensive attitude whereas his semiotic behavior reflects the pain of the truth, and that since that moment, he will not be able to settle; his identity is undecidable between Israel/ Palestine, Zionists/ Palestinians, Colonizer/ Colonized, Judaism/ Islam... Kanafani provides a criticism of the Self, here. As the Palestinians of 1948 escaped from their homes forsaking their land to the foreign occupation and then they (with the Arabs and Muslims) did nothing to restore it but waiting and weeping. Kanafani's self criticism is healthy as being the first step towards profoundly diagnosing the problem, the loss of Palestine, so as to find practical final solutions for the problem.

Although the primary intraosseous angioma or hemangioma, although it rarely affects the bones of the orbit, it should be taken into account in the differential diagnosis in those patients who present a fixed mass in the orbit or signs of progressive proptosis, sometimes not painful. For the therapeutic approach, it is critical to assess the exact location and extent of the lesion by CT and MRI, and to establish whether it has a vascular origin, since improper management can lead to severe bleeding. Surgical treatment is indicated for progressive proptosis or cosmetic deformity. We present the case of a patient with primary intraosseous hemangioma of the supralateral rim of the orbit, we review the bibliography of this very low prevalence disease and we trust that in this way, we contribute to the casuistry.

Nitrogen is one of the critical nutrients regulating terrestrial and aquatic productivity, and is linked to degradation of water quality of freshwater and marine ecosystems worldwide. The landscape patterns of stream nitrogen components, concentrations and loadings and their relationships with climate variability and landuse, were analyzed and quantified in this study. We used stream nitrogen concentration data collected at 2,125 sites and climate data at 301 weather stations during 1976 to 2005 in 30 eco-regions across British Columbia, Canada. While the patterns of stream nitrogen component, concentration, and loading distributions were found to be related to landscape patterns of climate variability, human activities, landuse, natural vegetation, and relief across British Columbia, the climate variability on both temporal a d spatial scales were found to be the dominant driver of variability in loading and concentrations of nitrogen. Elevated air temperature gradient across the landscape of British Columbia resulted in a significant increase in stream nitrogen loading from terrestrial into aquatic ecosystems. Precipitation, nitrogen deposition, population density and urban area also significantly affected the stream nitrogen components, concentrations and loadings. We suggest that climate change, especially shifts in temperature and precipitation, along with increased human activities tend to have important implications for loading of nitrogen from terrestrial to aquatic ecosystems and associated water quality in aquatic ecosystems

The goal of power sector in Nigeria is to efficiently and reliably transmit electrical power to all parts of the country which are made up of thirty-six states of the federation and the federal capital territory. The constituents of electrical power system are the generation, transmission, distribution and the utilization of electrical energy. There is gross power imbalance between the generation and the required power demand which has culminated into a defective economy in the last three decades. This paper therefore examines the power imbalance between the generation and power demand by the consumers and therefore stresses the need to harness the opportunity of renewable energy generation close to the gap between the power generation and power demand. This will help in transmitting and distributing efficient, effective, reliable power to consumers and improve both human and capital development. The availability of renewable energy sources such as sun, wind and small hydro power will be explored for the future of power generation in the country to fill in the gap between power generation and demand in Nigeria

Road Adaptation to Climate Hazards: Guidelines for Cost-Effective Measures
Authors:   Dr.Ing. Civil Engineer, Mouratidis Anastasios
Published: November 2021

Climate change and extreme weather events present a significant challenge to the safety, reliability, effectiveness and sustainability of every transportation system. Extreme weather events such as tsunami waves, wildfires, floods and hurricanes constitute a big risk for the integrity of the road transport system, since they can severely harm the infrastructure and its assets. Far more disastrous is the eventual direct impact on passengers, vehicles and goods, suddenly and unforeseeably hit by the weather event while moving on the roadway. In the field of road adaptation to climate threats, different scientific approaches have been developed but they have not produced, so far, the expected results, as the road transport sector still suffers from extreme climate hazards. The present scientific paper investigates the reasons for this failure and suggests a different perspective for realistic and cost-effective measures of proactive character to reinforce the road infrastructure and to increase its resilience to climate threats. It makes distinction between preventive and protective measures, including intercepting engineering assets and digital alarm systems. Moreover, the scientific paper introduces several key-points, in terms of fundamental recommendations of a different perspective of the climate change impact on the road infrastructure. In this regard, it may constitute a useful tool for transport authorities and operators to rationally plan interventions on a road network scale.

Published: November 2021

Conservation agriculture has been considered as the potential not only to increase the sustainability of agricultural productivity, but also to help works toward mitigation and adaption of climate change. Farming and soil management practices included in conservation agriculture are based on three core principles, which must be fulfilled concomitantly Minimum soil disturbance, Maintenance of permanent soil covers and Cropping system diversity, crop rotations. The objective of this document is therefore to review the implementation status, opportunities, challenges and limitation of conservation agriculture practices in Ethiopia. Conservation agriculture has economic as well as climatic advantages. The soil conservation practices, including minimum or no tillage have long been practiced by farmers with different approaches or systems in Ethiopia, conservation agriculture and its associated package of best practices were introduced in 1998. Presence of traditional practices contributing for conservation agriculture principle and socioeconomic and extension facilities are some of factors affecting adoption of conservation agriculture in Ethiopia while, Climate change prevention activities and untapped opportunity for the wide-scale promotion are some opportunities for adoption of Conservation Agriculture in Ethiopia. The principal goal of climate smart agriculture is identified as food security and development, while productivity, adaptation, and mitigation are identified as the three interlinked pillars necessary for achieving this goal. Key challenge with mainstreaming conservation agriculture systems relate to problems with up-scaling which is largely due to the lack of knowledge, expertise, inputs (especially equipment and machinery), adequate financial resources and infrastructure, and poor policy support.

This paper focuses on relevant legal and policy arrangements necessary for the development of Carbon Capture and Storage (CCS) in China. Special attention is paid to laws and policies on the capture, transport and storage of CO2. In particular, the storage of CO2 is very challenging for the existing regulatory regime, considering the complexity and novelty of the issue. Specifically speaking, the following analysis is made from three perspectives: (1) regulatory regime; (2) fiscal and financial support and (3) environmental regulations (including access to information and public participation). Having summarized and analyzed relevant issues and international experience, this paper identified the foundation, barriers and gaps exist in China. Priority choices and targets for legal and policy development in different periods were also made according to the status quo of CCS development in China and the periods of development recommended by the Asian Development Bank.

Reserved areas play vital role in preserving biodiversity and mitigating threats to climate change at local and world levels. Climate change that is already observed in many parts of the planet is the biggest and most horrible perspective facing our planet in near future. Adverse climate change processes are observed in Georgia too. In last decades biodiversity loss and increased natural disasters frequently take place. Scientists warn that if we will not be able to stop warming process at 1.50C we cannot be able to avoid unpredictable and irreversible consequences. Ecologists agree that enlargement of the existed reserved areas and creation of new ones will help to preserve biodiversity and mitigate climate change. They propose to enlarge the existed reserved areas up to 30% by 2030 and designate 20% of territory under strict monitoring [1]. At the same time we are sure that most of the local governments will not be happy by implementation of this idea and we believe that it must be supported and monitored by international nongovernmental organizations.

A survey of the literature indicates that most of them are handled with unsatisfactory practices that negatively impact the environment. Therefore, it is very important that they be utilized for more beneficial purposes, particularly in the context of the development of biofuels via pyrolysis technology. Due to its high carbon content, rich in lignin and low cost, empty fruit bunch (EFB) shows potential to be a good precursor for the production of biochar. The pyrolysis temperature greatly affects biochar properties and its potential usage. Many researches work on biochar have been carried out to assess its potential by investigating its characteristics. The most common thermochemical technique to produce biochar is pyrolysis, during which the organic components are decomposed at adjustable temperature in a nitrogen-limited atmosphere. The focus of this study is to identify the effect of temperature (300, 350, 400, 450 and 500 °C) on calorific value of pyrolyzed EFB derived biochar. Eight experimental runs were conducted. The results were completely analyzed by Analysis of Variance (ANOVA). The model was statistically significant. The factor studied which temperature was significant with p-values < 0.0001. The value of R2 was 0.9633 which indicated that the temperature showed high correlation to the calorific value of biochar from EFB pyrolysis process. A quadratic model equation was developed and employed to predict the highest theoretical calorific value. The maximum biochar calorific value was achieved at pyrolysis temperature of 500 °C. Char yield was obtained highest at 300°C around 53.36 wt% and started to decrease as temperature increase. Result of this experiment revealed that the calorific value of biochar increases as the temperature increases while the yield percentage of biochar decreases as the temperature increases. The yield of biochar decreases with temperature because of the secondary tar reactions of the volatiles, such as thermal cracking, that favors the increase of gas yield.

Ten water and ten sediment samples from both Igbokoda and Apapa in South west, Nigeria were collected between March and August, 2018 for heavy metal analysis. The study aimed at using Potential Ecological Risk (PER) index to characterize rivers sediments and waters for possible environmental impact. The sampling span industrial, domestic and recreational areas. The water and sediment grab samples were treated using standard procedures. The filtrate from sediment was made up to 50 cm3 mark with distilled water and used for seven heavy metals determination using atomic absorption spectrophotometry (AAS). Contamination factor (CF) and Pollution load index (PLI) calculated for each metal in the sediments indicate moderate contaminations. However, Cd in exception showed the highest potential ecological risk factor of 42.3 in Igbokoda. PER value of the Igbokoda sediment is 45.37 while that of Apapa sediment is 6.79. The potential risk pose by Cd alone in the sediment suggests that the Igbokoda water is unsafe for recreational and other beach activities. The recommendation from the study will suggest a proper treatment of wastewater and sewages before fluxing into both the Igbokoda and Apapa water bodies
Seismically-Induced Soft Sediment Deformation Structures In and Around Chamoli, Garhwal Himalaya, India
Authors:   Indian Institute of Geomagnetism, Navi Mumbai, India, Lakshmi BV
Published: November 2021

Soft-sediment deformation structures were identified along Nandakini River valley near Chamoli village of Garhwal Lesser Himalaya. The deformation, in each outcrop, is restricted to a single stratigraphic layer bounded by undeformed flat-lying layers, eliminating the influence of slope failure. The structures are multiple liquefaction features like sand dikes, flame structures, pear-drop disturbance and downward warping of beds. The preferred interpretation is that the deformations resulted from earthquake-induced liquefaction and their existence adjacent to the Nandaprayag Fault can be related to episodic seismicity that occurred along this fault. However, more data and dating technique is needed to constrain the timing and distance to the causative seismic source. It is possible that more than one earthquake has effected the deformations.

In Brazil, due to its extensive coastline and climate, there is a great potential for tourism, showing over time the increase in waste that has been incorrectly disposed of. These residues have clearly affected marine animals and even some birds due to being trapped or ingested, leading to the extinction of some species. This work aims to classify the main types of waste left by the population on the beaches of the West Zone of Rio de Janeiro, in addition to promoting the awareness of bathers about the impacts on the environment and aquatic life, caused by this waste disposed in incorrect locations. The most abundant items cataloged on the analyzed beaches were cigarette butts, tin rings, bottle caps, charcoal used in barbecues, straws, leftover food that attract many pigeons, among other microwaves. Thus, it is important to emphasize that the best measure to reduce the number of residues on the beaches as well as in other ecosystems is Environmental Education, through awareness about the consequences that residues can generate marine life biota.

This research was conducted Bangladesh (BD) and revised as an especial task study and review perspective of the coastal conditions and the features thus determine and critical analysis of integrated coastal zone management (ICZM). The coast length of Bangladesh is 710 kilometers wide. The coastal and ecosystem and habitats of the different animals are mostly depend on the features of coastal ecology and data analysis of both countries which have different strategies and techniques for the conservation of coastal biodiversity which were focused and brought together. Bangladesh coast contains vast biodiversity which are supported by the shingle beaches & sand dunes. The main features of the physical characteristics are the creeks, a lot of channels with crossing line, deltas of Ganges tidal plan with very low topology and mangroves. Integrated Coastal Zone Management (ICZM) in Bangladesh are greatly different because of variation in advanced and developed technology and the system of the creating legislative recommendations also varies; which could determine changes in sea level and coastal resources as well as habitats. This study targets to detect the background of coastal zone management (ICZM), scope, coastal development, challenges, environmental impacts, and necessary measures. Now, integrated coastal zone management (ICZM) is used for coastal development strategy in BD.

Plants are natural resources essential for human survival, with which local populations establish important cultural relationships to meet their basic needs. Such relationships involve local knowledge that is little considered in the pedagogical practices of school education. As a result of this reality, this research focuses on the contribution of the approach of local knowledge of medicinal plants in the teaching of Botany content in a rural school, located in the municipality of Caroebe in Roraima, in 2017. To access the knowledge, we use questionnaires with students from a class of the 2nd year of high school and also, diversified didactic activities were carried out in the approach to the content. We proved that the development of the didactic sequence with local knowledge favored the understanding of the contents of Botany and contributed to the involvement of students in the proposed pedagogical activities.
