The impact of trade liberalisation on mining sector total factor productivity: Evidence from developing countries
Authors: Choga Ireen , Mufandaedza Shylet Masunda
Published: February 2022

While the paradox of plenty is given much weight on raging debates on resource endowment and growth path of the Southern Africa Development Community (SADC) countries. The study seeks to establish the effect of trade liberalisation on mining total factor productivity. The study employed panel data of selected seven countries from the SADC for the period 1990–2017. The countries in the sample include Botswana, South Africa, Tanzania, Namibia, Zimbabwe, the Democratic Republic of the Congo (DRC), and Zambia, and were chosen based on data availability. Hicks-Moorsteen productivity index was applied to generate the total factor productivity change. A panel auto regressive distributed lag model (PARDL) and pooled mean group (PMG) are the estimation techniques used. The inquiry is crucial to SADC because mining production is a source of foreign exchange that directly contributes to economic growth. However, with open economies of SADC study expects the easy flow and diffusion of technology to aid productivity in the mining sector (Griffith, Redding, & Van Reenen, 2014). Results indicate a positive and statistically significant long-run relationship between trade openness and total factor productivity change in the mining sector. The study recommends progressive trade openness in the mining sector, human capital development, research and development to augment technology transfer.
Evolutionary opportunity and the limits of community similarity in replicate radiations of island lizards
Authors: Frishkoff Luke , Lertzman-Lepofsky Gavia , Mahler D. Luke
Published: February 2022

Ecological community structure ultimately depends on evolution producing
community members. To understand how macroevolutionary processes shape
communities, we surveyed Anolis lizard assemblages across
elevations on Jamaica and Hispaniola, neighboring Caribbean islands
similar in environment, but contrasting in evolutionary richness. The
impact of diversification on local communities depends on available
opportunities for speciation within or between ecologically distinct
sub-regions. Where opportunities abound, as in the vast lowlands of both
islands, communities converge in species richness and average
morphology. But community structures diverge in the highlands. On
Jamaica, where limited highland area restricted diversification,
communities remain depauperate and consist largely of elevational
generalists. In contrast, a unique fauna of high-elevation specialists
evolved in the expansive Hispaniolan highlands, augmenting highland
richness, and driving islandwide turnover in community composition.
Accounting for disparate evolutionary opportunities may illuminate when
regional diversity will enhance local diversity and help identify the
causes of convergent versus divergent community structure.

Thoracoscopic management of iatrogenic cardiac perforations
Authors: Langenaeken T. , Berg M. Van den , Kaya A. , Yilmaz A.
Published: February 2022

Aims: Iatrogenic cardiac perforation is an uncommon but
potentially fatal complication of invasive cardiac procedures. When
non-surgical management fails, urgent cardiac surgery is required.
Standard surgical approach is usually through full sternotomy. However,
we propose a less invasive and equally effective technique with
video-assisted thoracoscopic surgery (VATS).  Methods: This
single-center retrospective study in a tertiary hospital identified all
patients requiring surgical intervention due to iatrogenic cardiac
perforation over a period of 5 years. Patients were grouped by surgical
approach, being either sternotomy or VATS. Primary endpoints were length
of ICU stay, hospital stay, 30-day mortality and all round mortality.
Results: 25 patients were identified: 11 in the
sternotomy-group and 14 in the VATS-group. Preoperative baseline
characteristics were equal. Significant difference was found for 30-day
mortality (p < 0.05). There was no difference for the other
endpoints. Conclusions: Video-assisted thoracoscopic surgery is
a promising alternative to standard sternotomy for iatrogenic cardiac
perforations after invasive cardiac procedures.
Reproductive dispersion and damping time scale with life-history speed

Published: February 2022

Generation time has previously been the focus of comparative life
history analyses. Here we examine three metrics: generation time
T, reproductive dispersion S (the
distribution of ages of reproduction), and damping time τ (time
to converge to stable (st)age distribution). We use data on 633 species
of animals and plants, and perform phylogenetically corrected analyses.
First we find that S varies allometrically and isometrically with
T. As a result, τ varies allometrically
with either T or S but not both. Second,
we find a trade-off between τ and S, so that τ does
not vary isometrically with T. This trade-off is
a novel demographic component to the relationship between τ,
T and S that is otherwise partly
determined by their similarity as biological times. Our results indicate
that species at the slow end of the slow-fast continuum take longer to
converge to stable distribution than species with fast life-histories.

Background:In prediabetes, neither individuals having diabetic range nor normal glycemic parameters in terms of fasting plasma glucose, impaired glucose tolerance or glycated hemoglobin. Two-thirds of those with prediabetes will ends eventually with type 2 diabetes. Early detection with the proper intervention will halt or reverse this progression. Data about prediabetes prevalence in Iraq are scarce. Objective:To estimate the prevalence of prediabetes among adults in Baghdad/Iraq and to identify socio-demographic and associated risk factors among the studied population and to evaluate glycated hemoglobin in the detection of prediabetes. Methods:This cross-sectional study enrolled adults (20-79 years) attending primary health care centers in Baghdad/Iraq for one year, those with known diabetes or on anti-diabetic drugs, pregnant women and those with other medical conditions that interfere with glycated hemoglobin level were excluded from the study. Data collected through direct interview. Anthropometric measurements and laboratory analysis after overnight fast were done to measure fasting plasma glucose, glycated hemoglobin and lipid profile. Results:Prediabetes prevalence was 20.6%. Prevalence was higher in older people (40-60 years) and individuals with overweight, obesity, and dyslipidemia, the agreement between fasting plasma glucose and glycated hemoglobin was very good. Conclusion:Prevalence of prediabetes in Iraq is higher than estimated and share the same risk factors to those with type 2 diabetes. Glycated hemoglobin compared to fasting plasma glucose, is a reliable test to screen for prediabetes in Iraq.

Background: Measles is a highly contagious viral disease. It remains an important cause of death among young children globally, despite the availability of a safe and effective vaccine. Measles transmitted via droplets from the nose, mouth or throat of infected persons. Objective: To evaluate the immune response to measles infection among immunized school aged children, and to detect the cluster of differentiation 46 single nucleotide polymorphism (CD46 SNP) in association with the immune response. Methods: The current study is a cross sectional study including 158 hospitalized patients were previously vaccinated with two doses of measles-mumps-rubella vaccine. The ages of patients were 5-10 years school aged children. All samples were collected from blood collection unit in Al-Imamein Al-Kadhimein Medical city during the period from December 2018 to April 2019. The detection was based on the presence of IgG Antibody to measles. The positive results were considered according to enzyme linked immunosorbant assay and conventional polymerase chain reaction to detect CD46 SNP. Results: Among those 158 subjects' male children count for 62% and female children were 38%. Forty-one (41) immunized children (with mean age 7.98±1.92 years) were low immune response to measles vaccine (MV). On the other hand, only two cases (with mean age 5.50±0.71 years) were negative to measles virus vaccine. Conclusion: Ensuring two doses of MV give protective immune response to MV may declines with aging. CD46 cellular receptor gene SNP (rs7144) may play role in reduction in immune response to MV.

Authors: Redzek-Mudrinic Tatjana , Kavecan Ivana , Koprivsek Katarina , Rakic Goran , Pajic Jasmina
Published: February 2022

Introduction. Myelin oligodendrocyte glycoprotein antibody associated disorders (MOGAD) are immunemediated inflammatory conditions of the central nervous system (CNS) with a wide clinical phenotypic variability. In order to further understand the possible phenotype of MOGAD here we report a pediatric case of acute disseminated encephalomyelitis (ADEM) associated with MOG antibodies. Case outline. A previously healthy four-month-old infant presented due to a 1-day history of fever up to 39?C and vomiting. On admission, she was encephalopathic. Repetitive and frequent stereotyped dystonic movements were observed. Cerebrospinal fluid (CSF) examination showed pleocytosis (lymphocytes were predominant) and proteinorachy. CSF culture and virology results were negative. Serum MOG antibodies were positive. A prolonged electroencephalography showed continuous high-amplitude slow rhythmic activity with captured stereotyped movement. Epileptic discharges were not seen. Although magnetic resonance imaging showed signs of acute demyelinating encephalomyelitis, our patient did not have seizures, despite neuroimaging findings of cortical lesions. Acute treatment with the corticosteroids led to excellent response with full recovery. Conclusion. This case emphasizes the inclusion of the MOG antibodies testing in the initial work-up in children presenting with acute encephalopathy associated with demyelinating or encephalitic abnormalities on brain and/or spinal magnetic resonance imaging even when the clinical phenotype is unusual. The prompt diagnosis of MOGAD is relevant for accurate disease monitoring and treatment strategies.

Published: February 2022

A double J retractor (DJR) and palatal miniscrews were used to retract maxillary anterior teeth after failure of buccal posterior miniscrews. The line of action passing through the center of resistance of the maxillary anterior teeth and the moment generated by the palatal miniscrews via torquing springs successfully controlled the overbite and incisor torque during space closure. The DJR and palatal miniscrews work well with labial fixed appliances to address bimaxillary protrusion.
Influence of personality traits on a patient's decision to accept orthognathic surgery for correction of dentofacial deformity
Authors: Vidakovic Renata , Zigante Martina , Perkovic Vjera , Spalj Stjepan
Published: February 2022

Objectives

To investigate the influence of personality traits in addition to quality of life (QoL) on the decision to accept orthognathic surgery.

Materials and Methods

A total of 108 patients (68% female) aged 14–53 years (median, 18 years; interquartile range, 17–25.75 years), with skeletal malocclusions of Index of Orthognathic Functional Treatment Need grades 3–5 (moderate to very great need for surgery) were included in this cross-sectional study. Personality traits of extraversion, neuroticism, agreeableness, openness, consciousness, perfectionism, and self-esteem and dimensions of Orthognathic Quality of Life Questionnaire were compared between patients who accepted orthodontic preparation for orthognathic surgery and those who refused (n = 55 vs 53).

Results

Patients who accepted the suggested surgical procedure had higher age, perfectionism, facial esthetic (FE) concern, social aspect, and impairment of oral function (OF) as well as lower self-esteem with small to medium effect sizes (P ≤ .040; r = 0.198–0.399). Other personality traits and awareness of dentofacial deformity did not differ between the groups. In multiple logistic regression analysis, while controlling for sex, perfectionism, and self-esteem, the following predictors of acceptance of orthognathic surgery were higher: FE concern (odds ratio [OR], 3.4; 95% confidence interval [CI], 1.3–9.1), OF (OR, 3.0; 95% CI, 1.0–8.6), and age ≥18 years (OR, 2.7; 95% CI, 1.0–7.1; P < .001).

Conclusions

Extraversion, neuroticism, agreeableness, conscientiousness, and openness do not significantly affect a patient's decision to accept orthognathic surgery. The influence of self-esteem and perfectionism is primarily on perception of alteration of QoL induced by dentofacial deformity.

CHURCH-DEFENSIVE COMPLEXES 17th CENTURY IN CHERNIHIV REGION
Authors: Bondar Oleksandr
Published: February 2022

The article considers such a historical and fortification phenomenon as church defense complexes. Their existence dates back to the late MiddleAges and Early Modern Times. This type of fortified structures was spread on the territory of such modern countries as the Republic of Poland, the Czech Republic, the Republic of Belarus, and Romania. Ukraine is no exception. The question of the existence of church defense complexes or defense churches was considered by Ukrainian historiography during the 20th century exclusively on the territory of the Western Ukrainian and part of the Right Bank of Ukraine. However, the question arises whether such complexes existed on the Left Bank of Ukraine including Chernihiv region? The problem with the allocating of this type of fortifications in Chernihiv region is problematic due to the fact that they were wooden. Today there are almost no traces of them left on the earth's surface. These complexes can be studied only by a small number of written sources, as well as archaeological remains. Therefore, by the beginning of the 21st century they did not come in a view of researchers. A brief review of the above issues in this article allowed us to make some conclusions. The article gives an example of 7 complexes that could be classified as defensive. These are primarily churches in such settlements as Stolne, Loknyste, Veresoch, Kladkivka, Pechi, Olenivka and Saltykova Divytsia. In general, these were architectural ensembles consisting of a wooden fence or a stockade, the church sometimes with the bell tower. The bell tower also simultaneously served as an observation and signal point, defensive tower. Such defensive churches were not stationary fortresses. They served as temporary fortifications in case of sudden Tatar attacks. Тhe military and political situation in the Left Bank of Ukraine stabilized at the beginning of the 18th century. Due to that fact church defensive functions gradually disappear with its fortification elements.
METHOD OF VISUAL INSPECTION OF THE CASTLE IN THE STATE OF LONG-TERM RUIN
Authors: Gavryliv Кalyna-Theodora
Published: February 2022

The main task of visual inspection of an architectural object is to collect information about its current state and identify architectural peculiarities. Since the research information is obtained directly at the site of the study, which is characterized by a short period of time, – the operational fixation of information is a critical element. For this task, a method of visual inspection of the structure was formed, presented using the example of castles in a state of long-term ruin, including preliminary preparation for leaving to the research object, step-by-step instructions for the survey process and recommendations for processing and storing data later. A visual inspection of a castle in ruins requires careful preparation. First of all, you should familiarize yourself with the historical, bibliographic and iconographic base of the architectural object and form its construction chronogram. You should prepare a plan scheme with marked objects, where you will indicate saved, lost and emergency areas, and mark the change of masonry, the number of loopholes, etc. It is also recommended to prepare a text card of the visual examination, which will include the name of the investigated volume, short pre-collected information and free space for recording the examination results directly on the site. It is necessary to have a meter tape measure, a camera, if possible, a laser rangefinder and a drone. Since the route of the visual inspection is often quite chaotic, you should have another printed plan-schema to record the progress of the research. This manipulation will be helpful when you have to understand a few hundred photos. After processing the data in office conditions, a file which is called “Map of visual inspection of the castle in a state of long ruin” is formed. The castle-ruin reflects in its structure about six centuries of human history. Its research will be relevant for a long time, since funding for architectural monuments is extremely limited, and destructive processes are constantly ongoing. Given the versatility of the castle’s architectural site in a state of long-term ruin, visual inspection can be an excellent learning experience for restoration students. The study of the object of research contributes to the understanding of its potential and the emergence of ideas for its revitalization.

Corrosion is a chemical reaction that occurs in materials made of iron such as steel.  Steel that is experiencing corrosion will appear dark brown spots, the longer it is getting more and more and can cover the entire surface. Corroded steel will result in a major deterioration and structural failure because the thickness of the steel will decrease over a period of time, so the safety of the building is clearly not guaranteed[1]. Research on the tools used to detect the corrosion value of steel has been carried out. However, not using the internet of things technology. Therefore, a web-based corrosion monitoring or monitoring system was designed. The web will display data on voltage and temperature values ??in the form of numbers and charts. In addition, the website can also send SMS and Whatsapp message notifications if the value obtained exceeds the threshold. In developing this website using the prototype method, Laravel Framework, PHP and Java programming languages, MySQL database, Guzzle, and Whatspie as automatic message sending bots. System can provide information of monitoring regarding dummy, active and delta voltage along with their time and temperature.

Authors: Putri Novia Utami Putri , Khairudin Khairudin , Purwasih Nining
Published: February 2022

The stability of the electric power system is divided into transient stability, steady state stability and dynamic stability. Things that affect the performance of the generator include the addition of generators, changes in the load that vary in the system which have an impact on system stability and the distance between the generator and the load. The addition of a Virtual Synchronous Generator (VSG) is needed to improve the power system that is integrated with Renewable Energy Systems Source in maintaining system stability. When the integration between conventional generators and Renewable Energy Systems Source without Virtual Synchronous Generator (VSG) has a frequency response of 58.2 Hz when the generating capacity is -40% of the initial state, while integration between conventional generators and Renewable Energy Systems Source with Virtual Synchronous Generator (VSG) has a steady state response of 60 Hz even though the generating condition is 40% of the initial capacity of the generator. This means that the Virtual Synchronous Generator (VSG) can stabilize the return frequency in its nominal value on the system.

Mechanical properties improvement of Self Compacting Concrete (SCC) using polypropylene fiber
Authors: Noorhidana Vera Agustriana Noorhidana , Irianti Laksmi Irianti , Junaedi Tas'an Junaedi
Published: February 2022

SCC (self-compacting concrete) is a type of concrete that can compact itself without the help of external compaction. Thus, it can fill all parts of the formwork that are narrow and have tight reinforcement. A problem that often arises in the use of SCC is the segregation of concrete mixture, which reduces the strength of the concrete. This paper presents the effect of polypropylene fiber on the fresh concrete workability, compressive strength, splitting-tensile strength, and flexural-tensile strength of SCC concrete. The variations of the polypropylene fiber added to the SCC mixture are 0%, 0.05%, 0.067%, 0.1%, and 0.15% of the concrete’s volume, with a water-cement ratio of 0.5 and 0.38 and dense-graded and gap-graded coarse aggregate. Each concrete variation is made into cubes (150x150x150 mm3) for the compressive strength test, cylinders (dia.150mm; height 300mm) for splitting-tensile test, and prisms (100x100x400 mm3) for the flexural-tensile test. The experiments were carried out with concretes with the age of 28 days. The result showed that, polypropylene fiber could reduce the segregation in the SCC concrete mixture. The optimal polypropylene fiber percentage is 0.05%, which could improve the compressive strength by 12.2%, the splitting strength by 17.7%, and flexural strength by 322.3% compared to SCC concrete without polypropylene fiber.
Good: to Ward the Development of a Relational Antropology
Authors: Sсhindler D.C.
Published: February 2022

Abstract. The author takes as basis the encyclical of Pope Benedict XVI, where he substantiates that one of the root modern issues is an essentially individualistic interpretation of the person. The author analyzes the problem of isolation, which in its turn can be viewed as the source of multiple problems, including material poverty. In the context of this viewpoint the author reflects on the nature of “Goodness”, – Common Good that underlies human society. Individualism, strongly rooted in the West, leads to inferior understanding of the Goodness. To improve the situation we should abandon this approach, as real community can be based only on the Goodness that can be shared, and according to the author, this means that this Goodness can be “owned” by several people at the same time.
Postmodern Paradigm: the Last Resort of Secularism
Authors: Sankova Svetlana M.
Published: February 2022

The article presents an attempt to create a holistic description of the worldview paradigm of postmodern, as well as behavioral attitudes based on it. For this, the author applied the method of sequential analysis of the concept of “modern” possible interpretations and the construction on their basis of possible concepts of “postmodern”. The solution of such a problem within the framework of the article can’t claim to be detailed, therefore only the main lines of development of postmodernism as a socio-philosophical phenomenon as a whole and its individual concepts are outlined here. Also the author presents alternative options for the development of such concepts as “post-rationality”, “post-Christianity” and “post-civilization”.
25 YEARS IN THE COUNCIL OF EUROPE AND THE DEBATE ON THE BINDING NATURE OF ECHR RULINGS AGAIN
Authors: SULTANOV A.R.
Published: February 2022

The article considers the binding nature of legal positions of the European Court of Human Rights in civil proceedings taking into account amendments to procedural codes and substantive laws and legal positions of the Constitutional Court of the Russian Federation. The analysis is carried out to disclose the legislator’s intention, the purpose of which was to create the “stop-block” against the excessive evolutionary interpretation, rather than to limit the application of legal positions, stated in the judgments of the ECHR. In conclusion, the author puts forward the thesis that the recent amendments to the legislation should not be interpreted as a refusal to implement ECHR judgments, but as an attempt to fix in its legislation the right to seek compromise in the event of new obligations for Russia from the evolutionary interpretation of the ECHR Convention. In our opinion, it is appropriate to quote the President of the Constitutional Court of Germany, who wrote that this approach is a kind of “stop-cock”, which is most effective when it is not used at all. It is its presence, not its absence, that avoids an emergency situation. The presence of a “stop-cock” should not be an obstacle to the protection of human rights and freedoms, nor should it be an obstacle to the enforcement of ECHR judgments, let alone a justification for violations of conventional human rights and freedoms.
CIVIL LAW REMEDIES IN THE ANGLO-SAXON (COMMON) LAW SYSTEM
Authors: LATYPOV D.N.
Published: February 2022

This article is devoted to the system of civil law remedies applicable in the common law states, in particular, in England. The subject of the research covers the specific civil law remedies which are applied by the courts and in self-defence, as well as generally applicable classifications of such methods of protection. The analysis of a vast number of judicial precedents concerning the application of the main methods of protection of civil rights has been carried out. The categories of civil law remedies, which are used in an out-of-court and judicial (including those used at various stages of the trial) procedure, have been highlighted. It was revealed that the main civil law remedy is compensation or compensation for losses of the plaintiff. It is shown that the protection of civil rights in Anglo-Saxon law is aimed at the most effective protection of the rights of the plaintiff, but not punishment or diminution of the rights of the defendant. It was also revealed that in Anglo-Saxon law there are similar (the same type) civil law remedies, which were formed in parallel in common law and the law of justice. Based on the results of the analysis, it was concluded that the system of civil law remedies in the common law is complex and overloaded, which complicates law enforcement and applying for protection of the right.
SOME ASPECTS OF DEFINING THE PROPER LITIGANT IN THE ARGUMENTS ABOUT HOUSING RIGHTS PROTECTION OF CIVIL SERVANTS AND THEIR FAMILY MEMBERS
Authors: AIBATULINA A.K.
Published: February 2022

The author analyses in details laws and regulations about the provision of one-time welfare payment to civil servants and their family members with the goal to define the proper litigant. There are also two units highlighted, in dependence on which the proper litigant can be defined: 1. On the territorial factor, i.e. place of employment of the servant; 2. In the cases of the breach of time limits of the servant application processing about their registration for receiving the one-time welfare payment. The author came to the conclusion that the proper litigant in the disputes about the invalidation of the decision about refusing to register (deregister) for the provision of one-time welfare payment is not a state body, but a commission (territorial commission) of the state body, agency, or other establishment, vested with governmental or other public authorities. The state body will be an interested party in accordance with the dispositions of Code of Administrative Judicial Procedure of the Russian Federation.

Authors: DYAKONOVA M.O.
Published: February 2022

The article examines the evolution of the positions of the Constitutional Court of the Russian Federation regarding the institution of indexing of awarded sums of money in civil and commercial procedure. The author comes to the conclusion that the norms on indexation in the Commercial procedural code of the Russian Federation and Civil procedural code of the Russian Federation require reform, taking into account the legal positions of the Constitutional Court of the Russian Federation in decisions No. 35-P of 23 July 2018 and No. 1-P of January 12, 2021, related to civil procedure, as well as in decision No. 40-P of 22 July 2021 related to the commercial procedure. In addition, the author assesses the prospects of applying the legal position of the Constitutional Court of the Russian Federation on the issue of indexation in the commercial procedure as a basis for reviewing judicial acts because of new circumstance. Сurrent regulation is criticized, according to which the basis for revision as a rule is only the recognition by the Constitutional Court of the Russian Federation of the law applied in a particular case, in connection with the decision on which the applicant appealed to the Constitutional Court of the Russian Federation, which does not comply with the Constitution of the Russian Federation. The conditions of retroactive effect of the decisions of the Constitutional Court of the Russian Federation in relation to judicial acts in connection with which the interested person did not apply to the Constitutional Court of the Russian Federation or whose complaint was refused by the Constitutional Court of the Russian Federation are revealed.
REFLECTING ON THE CONDITION OF THE MODERN CIVIL PROCEDURAL FORM
Authors: ARTEBYAKINA N.A.
Published: February 2022

The procedure for any of the types of legal proceedings is strictly regulated by the current federal law. Arbitrary deviations from the established procedural form are not allowed. Civil and arbitration proceedings are no exception. All actions of the court, persons participating in the case, other participants in the proceedings must obey certain rules, deviations from which are inadmissible in a state governed by the rule of law. Unfortunately, in practice, such violations are quite common, which are difficult to explain from the point of view of the law. The author of this article analyzed several examples from judicial practice. Within the framework of civil proceedings, there is a widespread substitution of concepts: instead of the legislatively established preliminary court session, the courts hold so-called «conversations», during which, for some unknown reason, the minutes are not kept. In addition, attention is focused on several specific examples illustrating the violation of the civil procedure form. This cannot indicate stability, confidence that the violated rights and legitimate interests of the subjects will be guaranteed to be protected in the manner prescribed by law. Departure by anybody from the rules established by federal law is unacceptable, entails a violation of the principle of legality – the fundamental principle of all branches of Russian law.

Ball-Mill Assisted Green One-Pot Synthesis of ZnO/Graphene Nanocomposite for Selective Electrochemical Sensing of aquatic pollutant 4-nitrophenol
Authors: P Kavya , S Soorya V , Narayanan Binitha N
Published: February 2022

ZnO, having good transparency, high electron mobility and lower electrical noise, is an excellent material for electrochemical studies. Due to its high surface area and electrical conductivity, graphene is well suitable for the good dispersion of metal oxides for electronic/electrochemical applications. Graphene prevents particle agglomeration, whereas the addition of metal oxide prevents layer restacking in graphene. The bulk preparation of graphene via cost-effective and green methods are preferred. The aromatic conjugated π-network along the whole surface is not attained in large scale graphite oxide assisted production due to the defects and functional groups introduced during the hazardous synthetic procedure. Here, less defective graphene is synthesised via ball milling of graphite using metal oxalate as an exfoliating agent for the first time. Calcination of metal oxalate inserted graphite leads to the enormous evolution of gases thereby sliding the graphitic layers, leading to the formation of graphene sheets decorated with ZnO spherical nanoparticles’ bunches. The layer exfoliation and metal oxide incorporation are achieved here via a one-pot synthesis strategy. The use of ZnO/graphene in the selective sensing of 4-nitrophenol is investigated using cyclic voltammetric measurements in the presence of interfering compounds such as glucose, uric acid, ascorbic acid and H2O2.

Published: February 2022

Sewage sludge is a usual waste from urban areas that can be utilized in many renewable energy sources. In this study, we examine the sewage sludge utilization using pyrolysis process to produce pyrolytic oil using Taguchi methods, combustion characteristic of sludge pyrolytic oil (SPO) blend with heavy fuel oil (HFO), and co-gasification of sewage sludge with CO2/steam as the gasification medium using Taguchi methods. The best-operating conditions for the pyrolysis of sewage sludge are a heating rate of 10oC/min, temperature of 450oC, the residence time of 60 min, and N2 flow rate of 700 mL/min. Under these conditions, the obtained pyrolytic oil yield is very close to the result from the Taguchi method calculation. In the combustion characteristic of sludge pyrolytic oil (SPO) blend with heavy fuel oil (HFO), a higher SPO in the fuel blend enhances the occurrence of micro-explosion and reduces the size of the residual. Higher SPO content in the fuel blend increases the combustion rate and increases the ignition delay due to moisture evaporation. In the co-gasification of sewage sludge and palm kernel shell optimization using Taguchi method, the best operational condition for maximum H2/ CO syngas ratio reaches at the gasification temperature of 900 C, a blending ratio of 30%, a CO2/(CO2+H2O) ratio of 70%, and a catalyst addition of 20% bed material mass. The best operating condition for maximum concentration of H2 reach with gasification temperature of 800 C, a blending ratio of 40%, a CO2/(CO2+H2O) ratio of 70%, and a 15% catalyst addition of bed material mass. The CO2/(CO2+H2O) ratio is the most important parameter among both case.
