Authors: Indrawati Titik , Sarto Sarto , Prasetya Agus
Published: August 2022

The study aims to compare the effectiveness of chromium removal from water using adsorption by coal fly ash (CFA) and phytoremediation by vetiver grass (Vetiveria zizanioides L) as well as a combination of both CFA and vetiver grass. The experiment was carried out in four different reactors, having size of 100 cm (length) x 60 cm (wide) x 80 cm (height). One reactor was filled with gravel and CFA, without vetiver grass (RI), while another one was filled with gravel and vetiver grass, without CFA (RIV). The other two reactors were filled with gravel, CFA, and vetiver grass with the mass ratio of gravel/CFA of (25:2) and (25:1), denoted as RII and RIII, respectively. Fifty (50) L of synthetic wastewater containing 14.612 ppm of chromium was filled into the reactors and continuously recirculated for 15 days. Chromium accumulation in CFA and plants was analyzed on day 15. The results of plant development are indicated by the presence of new shoots and roots that grow during phytoremediation processes. In addition, there was an increase in weight and number of vetiver stems indicating the persistency of vetiver grass in such a harsh wastewater condition. The removal of Cr from wastewater in RI, RII, RIII and RIV at days 15 were 81%, 93.2%, 85.8% and 75.7%, respectively. It can be concluded that: (1) vetiver grass (Vetiveria zizanioides L) has high potential as phytoremediator plant, (2) Chromium adsorption by CFA plays important role in Cr removal from wastewater, and (3) combination of adsorption by CFA and a phytoremediation by vetiver grass significantly increases the removal of chromium from wastewater.

Published: August 2022

Most majors in colleges and universities need to learn English, and English is also an important subject. Every student needs to master certain English skills and English learning ability. In the process of English learning, English is a foreign language, and the cultural characteristics and values contained in English language will be different or even conflict with Chinese language. Therefore, colleges and universities need to pay great attention to the values output by students when teaching English, and ensure that teaching is carried out in accordance with Chinese cultural requirements. That is to say, students’ cultural awareness should be cultivated in English teaching. Learning English language is not just learning grammar or words, but also learning the cultural awareness contained in languages.

Authors: Heaton Adam P
Published: August 2022

Is empathy a remedy for prejudice? This short paper argues it has a large role to play. It explores the authors’ observations as a Humanities teacher engaging Grade 8 Australian students between the ages of 12 and 14 in a study of the film Rabbit-Proof Fence. As students empathised with Aboriginal (Indigenous Australian) children forcibly removed from their families under Australian government policy in the twentieth century, they questioned the negative things they themselves had come to believe about Indigenous Australians.

Authors: Parveen Heena
Published: August 2022

The objective was to understand the performance differences of heavy and light media multitaskers. Further, the differences across media multitasking groups when the subjects are performing a cognitive task in the presence of music were studied to understand the role of music in cognitive performance in terms of cognitive control. A sample of 300 girl students from the Government schools of Chandigarh in the age range of 14-18 years (mean age= 15.7 years) was taken for the purpose. The media multitasking questionnaire (Ophir et al., 2009) and the Stroop task (Stroop, 1935) were used. The two media multitasking groups, viz., heavy and light media multitaskers, significantly differed from each other. Media multitasking and cognitive control were found to be linked and the role of music indicated facilitating trend for performance. Studies conclude high levels of media multitasking result in poor cognitive performance in terms of cognitive control and music plays a facilitative role for such media multitasker’s cognitive control.

This article has three sections. In section one, I define my terms which leads to an outline of what this New Paradigm is. In section two, I develop this paradigm and suggest a visualization of it, a structure as it were. This will assist in a more thorough understanding of such a paradigm. Theoretical speculations and modeling aside or rather avoiding a “purely” philosophical bias, I then apply this model to an example culled from art and aesthetics, yet involving, in line with this New Paradigm, other disciplines such as science and sport in order to exemplify or perhaps prove my argument, by virtue of the “mixture” or inter-disciplinary framework as applied to several different variables. This section forms the bulk of the article as such an application concretizes the theoretical framework in specific ways so that the reader will ascertain the usefulness of such a venture, which in turn ought to spur and spawn future research.

Published: August 2022

Agriculture is an important part of India's economy, and the dairy sector provides to the country's profitability. As we all know, the global has grown at a faster rate, with people embracing a more affluent lifestyle to meet shifting expectations and needs. As a result, it is critical to reform the current farming and dairy management practices in India in different criteria, such as FAT, classifications of various milk characteristics, and so on. Another concern is that the process is done manually, which makes it susceptible to errors. As a result, it is necessary to reduce physical labour to improve results. The current system must be replaced with a new one that utilizes automated milk sample measuring technology. In our proposed system, we have developed a low-cost and reliable milk parameter detection and analysis system that uses an Arduino controller. On the other hand, the milk quality is checked, evaluated, and shown in a matter of seconds. As a result, the goal of implementing the suitable information technology stated in this project is to make information symmetric in the market, thereby minimizing problems of adverse selection and tedious work.

Published: August 2022

Abstract: It might be challenging to focus on and solve the issues experienced by persons with disabilities, such as those who are visually, audibly, or verbally impaired, utilizing just one technology. The project's goal is to provide a single device solution that is easy to use, quick, accurate, and economical. A Raspberry Pi-based assistance for the blind, deaf, and dumb is presented in the study. The major goal of the technology is to provide persons with disabilities a sense of independence and confidence by seeing, hearing, and speaking for them. Vocally impaired persons can stand in front of the camera and conduct activities using sign language thanks to the suggested technology. The retrieved text is then converted into an audio format using speech synthesis and image-to-text conversion. For those who have trouble hearing, the input comes in the form of speech that is picked up by the microphone. Recorded audio is then transformed into text that is presented to the user in the window on the device's screen. The audio message may now be sent through the speaker to people who are blind.
Urban planning aspects of interaction between regional settlement systems and industrial areas subjected to special modes of operation
Authors: Yushkova Natalya G. , Nikiforova Daria N.
Published: August 2022

Introduction. Urban development of regional settlement systems depends on the administrative and territorial structure of the Russian Federation. The establishment of new types of municipalities, such as urban and municipal regions, municipal districts, in which urban and rural settlements function, is the evidence of modernization. Prospects of reorganization of regional systems also depend on the planning of territories of special economic zones as drivers of local changes in the regional systems and their individual elements. However, these prospects ensure their integrated development. To improve the manageability of regional settlement systems, it is reasonable to evaluate the pace of local urban development processes and forecast their consequences.

Materials and methods. To solve the problems of the study, the authors used methods of system-structural analysis, cause-effect analysis, operational analysis, theoretical and cartographic modeling. They also took advantage of the official statistics, space planning documents of the RF subjects, open-access cartographic sources, published results of research projects implemented by foreign and domestic researchers.

Results. Production areas with special modes of industrial specialization have been intensively forming in the regions of the European part of Russia for the past 15 years. Generalization and systematization of this practice show the same basic conditions of their formation, including such indicators as the area of the territory, the population size and density. Calculated extremums and average values of these indicators can be used to make a comparative assessment of the systems as a whole and their individual elements. Analysis of the sequence of the process of urban-planning arrangement of such territories, features of their location, character of functional and spatial communications, development potential, the state of belonging to the stage of establishment, various land use characteristics allow identifying basic classes and prerequisites of their involvement in the processes of intermunicipal and interregional interaction.

Conclusions. New properties and characteristics of regional settlement systems, conditioned by features of their administrative and territorial structure, have been identified. They are expressed in different states of regional systems described by the principle patterns: concentration, rarefaction and turbulence of urban planning processes. They determine prospective forms of reorganization of regional systems, based on the configuration and parameters of contact-junction zones of municipal and regional levels in the formats of conceptual substantiation and options of land use planning.
A solution to the problem of pile settlement caused by vertical static loading with consideration to plastic properties of the foundation soil
Authors: Ter-Martirosyan Zaven G. , Filippov Kirill A.
Published: August 2022

Introduction. The article addresses the problem of nonlinear analyses of structures having pile foundations. The purpose of the study is to develop a method for determining the nonlinear behaviour of a single pile. The tasks of the study are to use the analytical method to define and solve the settlement problem of a single pile, taking into account the plastic properties of soils along the lateral surface and under the tip, as well as to verify the obtained solutions using the field data obtained by testing the pile subjected to static loading.

Materials and methods. The analytical model of the telescopic motion of coaxial cylindrical soil layers around the pile was applied to obtain the solution. Pile settlement due to the punching of the bottom layer was calculated using the available formula dealing with a circular rigid stamp located at a given depth from the surface. To verify the solution, the authors used the materials of static loading tests conducted in respect of three reinforced concrete prismatic piles of the base of a hospital building located in the city of Tver. A static method was used to drive the piles.

Results. A comparison between the results of the analysis obtained using the proposed solution and the field test data is presented. The analysis of this comparison shows that the solution allows describing the load-settlement curve for the static loading of a single pile. A reasonable mismatch between the calculated and field data is identified; it is associated with the inability of the derived formula to take account of soil consolidation.

Conclusions.The solution, obtained for single pile settlement, takes into account plastic properties of soil on the lateral surface and under the pile tip. This solution describes the regularity of single pile deformation under static loading. Further research will take soil consolidation into account. The assumed values of the ultimate resistance of a pile along a lateral surface and under the pile tip have a considerable influence on the results of the calculation according to the solution obtained by the authors. A relevant task, to be solved in the course of further research, is to find alternative methods of their determination.
Determining the burst pressure of vent structures with account taken of wind loads
Authors: Korolchenko Olga N. , Korolchenko Anton D.
Published: August 2022

Introduction. In the Russian Federation, current regulations prescribe that enclosing structures of building premises, that are not explosion-safe, must have safety anti-explosive devices to ensure safe pressure inside the building (premises) and in the surrounding space.

Materials and methods. One of the most important characteristics of vent structures (VS) is their burst pressure, the value of which is determined in GOST R (State Construction Standards of Russia) 56288 “Double-glazing vent window structures for buildings. Technical conditions”; it shall not exceed 0.7 kPa. However this value doesn’t take into account the influence of wind loads on VSs, and this leads to contradictions arising between producers, designers and supervisory authorities. The purpose of this article is to determine the range of burst pressure values at which VSs will be able to perform their primary function, that is, to ensure the bursting of gas, steam, and dust-air mixtures at an early stage of an explosion and provide safe pressure inside the building.

Results. In this paper, calculations of principal and peak wind loads were made according to SP (Construction Regulations) 20.13330.2016 “Loads and impacts” to find out that the pressure of 0.7 kPa strongly limits the use of VSs in different wind regions. The burst pressure of translucent VSs was then identified experimentally for several structures subjected to the effects of an internal accidental explosion. The same specimens were tested for wind load resistance. It was also noted that in the process of determining the ΔPbur, the maximum allowable pressure should be considered for the selected building type.

Conclusions. As a result of the studies made by the authors, the range of the burst pressure was identified.
The application of innovative approaches to the process of determining the initial cost of fixed assets of oil and gas enterprises
Authors: Glazkova Valeriya V. , Belokonov Alexander V.
Published: August 2022

Introduction. Despite the barriers of the external environment, crude oil and gas recovery does not decrease, which causes an increase in the construction of oil and gas facilities. During the construction and commissioning of oil and gas facilities, objects directly involved in the production process are formed; these are the fixed production assets of oil and gas enterprises. To determine the initial cost of fixed assets, it is necessary to take into account all incurred to obtain them. Since we consider the construction of oil and gas facilities that will later have the status of fixed assets, it is advisable to study their initial cost from the standpoint of pricing in the construction industry. The purpose of the article is to present the author’s approach to the process of determining the initial cost of fixed assets of oil and gas enterprises. For this purpose, the article solves the tasks related to the identification of factors affecting the management of projects on the construction of oil and gas facilities, the study of innovative approaches to determining the cost of construction of oil and gas facilities at the pre-project stage, as well as the development of the author’s approach to determining the cost of construction of oil and gas facilities at the pre-project stage, and for objects involved in the production process after their commissioning, the authors study the composition of the initial cost of fixed production assets of oil and gas enterprises.

Materials and methods. The research methodology includes general research methods of analysis and synthesis, methods of expert and comparative assessments, as well as methods of pricing in the construction industry.

Results. The factors influencing management of projects on the construction of oil and gas facilities are addressed, and innovative approaches to determining the cost of construction of oil and gas facilities at the pre-project stage are considered. Hence, the authors present their approach to determining the cost of construction of oil and gas facilities at the pre-project stage, which can also be used to determine the initial cost of fixed production assets of oil and gas enterprises, if the objects under consideration are to be involved in the production process after commissioning.

Conclusions. The proposed approach will ensure an accurate and efficient estimation of the cost of construction of facilities at the pre-project stage; therefore, it will improve the accuracy of fixed asset cost estimates after the facilities are commissioned.

ASH synthesis was done by adding a 3-aminopropyltriethoxysilane (APTES) modifier to sodium silicate from Lapindo Mud. Phosphate binding was carried out at 30 minutes with a stirring speed of 250 rpm. Analysis using IR spectrophotometer showed the success of ASH synthesis as indicated by the appearance of functional groups -NH2 and -CH2 at wavenumbers 1635 cm-1 and 1473 cm-1. With the continuous method, SG and ASH sorbents that have bound phosphate were then desorbed at various times of 2, 3, 4, 7, 8, and 9 days. The amount of phosphate anion released from SG and ASH was tested using a UV-Vis instrument then modeling was carried out to determine the rate of phosphate release. The desorption results showed the amount of phosphate released from the ASH sorbent was less than that of the SG sorbent. Through modeling, the proceeds of the phosphate release rate follow the Lagergren Pseudo-second Order Kinetic with an experimental QE of 0.22089 M/g for SG sorbent and 0.33333 M/g for ASH sorbent.

Nickel extraction from Morowali laterite ore has been carried out with nitric acid as the solvent. This study aims to determine the effect of nitric acid concentration, temperature, and stirring time on nickel content in laterite ore originating from Morowali. Morowali laterite seeds were extracted using the leaching method using nitric acid as the solvent with various concentrations of 0.5, 1, and 2, temperatures of 30, 60, and 95, and stirring times of 3, 6, and 12. Taguchi analysis was used in this study to obtain the effect of the three parameters used. The results showed that the optimum conditions were obtained at a concentration of 2 molars nitric acid, a temperature of 95°C, and a stirring time of 12 hours, with a nickel content of 16.469 ppm and a nickel recovery percent of 3.88%.

A fast-transient output-capacitorless (OCL) low-dropout (LDO) regulator
with adjustable threshold push–pull stage (ATPS) and master-slave power
transistors topology is presented in this paper. The ATPS consumes
little quiescent current at light load current condition and the turn on
threshold of the proposed ATPS can be adjusted by a current source. With
the ATPS and master-slave power transistor topology, the proposed LDO
can be stable from 0 to 100 mA load current at a maximum 100 pF
parasitic load capacitance and a 0.7 pF compensation capacitor. It shows
good figure of merit (FOM) without extra transient enhanced circuit. For
the maximum 100 mA load transient with 100 ns edge time, the undershoot
and overshoot are less than 33 mv.

Authors: Folayan Olumuyiwa , Oyesola Bello Afeez , S.K Ernest
Published: August 2022

Background: The annual newborn population with structural
haemoglobin disorders is estimated at five million globally. Nigeria
accounts for over 30% of this and has a high under-five mortality rate
from undiagnosed haemoglobinopathies. Newborn screening and
comprehensive care significantly improve outcomes, but this is not
routine in Nigeria where Hb electrophoresis is used for diagnosis.
Objectives: This study determined haemoglobin phenotype
patterns and frequency in neonates attending immunization clinics in
Bida community, and identified factors associated with the occurrence of
haemoglobinopathy. Method: It was a descriptive cross-sectional
study that recruited 254 neonates by multi-staged sampling technique
from nine immunization centres. Haemoglobin phentype was determined
using High-Performance Liquid Chromatography (HPLC) testing of dried
blood spot samples. The Statistical Package for Social Sciences was used
to analyse the relationship between abnormal variants and identified
factors. Result: The Hb phenotypes found in this study were
HbFA- 73.6% (187/254), HbFAS- 23.2% (59/254), HbFAC- 1.6% (4/254),
HbFS- 1.2% (3/254), and HbFAD-0.4% (1/254). The frequency of an
abnormal variant was equal in both genders. The majority (89%) of
mothers did not know their Hb phenotype, 25% of these mothers had a
newborn with an abnormal phenotype, and 20% were married in
consanguineous marriages. Conclusion: Abnormal haemoglobin
variants were present in more than one-quarter (26.4%) of the studied
population. Most parents were unaware of their haemoglobin phenotype and
also had a wrong perception of sickle cell disease. Consanguinity did
not significantly affect the occurrence of an abnormal haemoglobin
phenotype.

Osteitis fibrosa cystica or brown tumor is a rare skeletal manifestation
of hyperparathyroidism. Awareness of this condition is imperative to
making a correct diagnosis. We present a case with multiple pathological
fractures who had undergone extensive workup for malignancy before
reaching the definitive diagnosis of primary hyperparathyroidism.

Objective: Untreated protracted bacterial bronchitis (PBB), a
chronic wet cough prevalent in children, may lead to chronic suppurative
lung disease or bronchiectasis. However, clinical diagnostic criteria
for PBB are nonspecific; thus, PBB may be misdiagnosed. Thus, we
assessed the diagnostic value of fiberoptic bronchoscopy (FOB) and risk
factors associated with PBB. Methods: Children with chronic
cough at First Affiliated Hospital of Anhui Medical University from
January 2015 to May 2020 were enrolled and allocated to a suspected PBB
(n=141) or a non-PBB (n=206) group. All children underwent extensive
laboratory, chest imaging, and allergen tests. Children with suspected
PBB underwent FOB with bronchoalveolar lavage; lavage and sputum samples
were cultured. Results: All 347 children had chronic wet cough
for approximately 2 months. Of 141 children with suspected PBB, 140
received FOB with bronchoalveolar lavage. Visible tracheal changes
included pale mucosa, mucosal congestion, edema, swelling, and increased
secretions attached to the wall. Sputum was visible primarily in the
left main bronchus (78.7%), left lower lobe (59.6%), right upper lobe
(62.4%), and right lower lobe (64.5%). Sputum properties and amounts
significantly differed between children with vs. without PBB ( P
< 0.05). Dermatophagoides (odds ratio [OR], 2.642; 95%
CI, 1.283–5.369) and milk protein (OR, 2.452; 95% CI, 1.243–4.836)
allergies and eczema (OR, 1.763; 95% CI, 1.011–3.075) were risk
factors significantly associated with PBB. Conclusion:
Dermatophagoides, milk protein, and eczema were associated with
increased risk of PBB. Sputum distribution and tracheal wall changes
observed through FOB may distinguish PBB and assist in its diagnosis.

Processing of fruits in Ghana leads to the generation of tonnes of waste
such as peels, seeds, cores and crowns. Handling this waste tends to be
a major challenge. The usual practice is to discard these wastes in
drainages, water bodies and in landfills. However, if these wastes are
used as feedstock to produce enzymes, bioethanol, and specialty
chemicals instead of being dumped in landfills or put in the ocean, this
unwanted environmental pollution can be avoided. Utilizing these wastes
as a resource for energy production such as bioethanol, which is
produced from the fermentation of reducing sugars is a means of
addressing the sanitation issue while valorizing the waste. The main aim
of this work was to use Response Surface Methodology, to estimate
conditions for the optimal production of reducing sugars from fruit
wastes via hydrolysis using enzymes. The substrate used compromised of
pineapple peels, pawpaw peels, mango peels and a blend of these three
fruit peels. Fruit waste samples were pulverized and aliquots of 2.5%
w/v, 5% w/v, 6% w/v and 7.5% w/v substrate concentration made for
analyses. Fruit waste samples were saccharified with commercial enzyme
procured from the market and samples taken from 12 to 72 hours to
determine reducing sugar yield. Central Composite Design, a statistical
design tool in Response Surface Methodology was used to investigate the
effect of two significant independent variables, hydrolysis time and
substrate concentration on the response variable, reducing sugar yield
in the hydrolysis process. Results indicated that cellulose and
hemicellulose were highest in pawpaw peels, 25.8% and 25.1%,
respectively. Saccharification with commercial enzymes showed that blend
had the highest concentration of reducing sugars at 7.5% substrate
concentration after 48 hours. Optimisation of process parameters gave
optimal conditions for pineapple peels to be time of 32.8 hours,
substrate concentration of 3.5% w/v, TRS yield of 16.6 mg/mL. That of
mango were optimal time of 34.2 hours, substrate concentration of 4.7%
w/v, a TRS yield of 27.8 mg/mL. Pawpaw peel had optimal conditions of
67.6 hours, substrate concentration of 5.1% w/v, TRS yield of 25.5
mg/mL. Peels blend had time of 61.7 hours, substrate concentration of
5.9% w/v and TRS yield of 45.4 mg/mL. These optimal conditions can be
followed for effective hydrolysis of fruit peels while cutting down on
time and cost associated with hydrolysis.
