Published: June 2022

Abstract: In this research work the modification of spark ignition engine for producing power using turbine. Nowadays in automobile field many new innovating concepts are being developed. We are using the power from vehicle exhaust to generate the electricity which can be stored in battery for the later consumption. In this project, we are demonstrating a concept of generating power in a stationary single cylinder engine by the usage of turbines. Here we are placing a turbine in the path of exhaust near the silencer. The turbine is connected to a dynamo, which is used to generate power. Depending upon the exhaust flow the turbine rotates, and this causes the dynamo to rotate. A dynamo is a device which is used to convert the mechanical energy into electrical energy. The generated power is stored to the battery. It can be stored in the battery after rectification. The rectified voltage can be inverted and used in various forms of utilities.

Published: June 2022

Abstract: Data storage and sharing services within the cloud, users can easily modify and share data as a bunch. to make sure share data integrity are often verified publicly, users within the group must compute signatures on all the blocks in shared data. Different blocks in shared data are generally signed by different users thanks to data modifications performed by different users. Encryption schemes available for data privacy but it limits the number of functions exhausted storage system. Building a secure storage system that supports multiple functions is hard when the storage system is distributed and has no central authority. a brand-new idea is proposed proxy re-encryption scheme for decentralizes erasure code for defending the distributed system. The easy method, which allows an existing user to download the corresponding a part of shared data, is inefficient because of the big size of shared data within the cloud. We propose a unique public auditing mechanism. Moreover, our mechanism is in a position to support batch auditing by verifying multiple auditing tasks simultaneously.

Abstract—Bridges are recognition of a nation’s infrastructure. Bridges play an important role in connecting people, good and transports. A bridge’s close down can halt economic progress of any nation. Services those are no longer available can be simply completed with the help of bridges. Most advanced technology that are used for bridge design and construction are Building Information Modelling (BIM), Prefabrication and computer aided AI-based system. Various new construction materials are also being used as a replacement for traditional materials. A Tied-arch bridge is an arch bridge in which the outward-directed horizontal forces of the arch are borne as tension by a chord tying the arch ends, rather than by the ground or the bridge foundations. A Suspension bridge is a type of bridge in which deck is hung below suspension cables on vertical suspenders. Suspension Bridge consists of main span, side span, main cables, hanger ropes, pylons and deck. Tied arch bridge is type of bridge in which deck is below the arch and vertical suspender ropes. A tied-arch bridge is an arch bridge in which the outward horizontal forces of the arch caused by tension at the arch ends to a foundation are countered by equal tension of its own gravity plus any element of the total deck structure such great arch support. The arch have strengthened chord that run to a strong part of the deck structure or to independent tie-rods below the arch ends. This research presents the Response Spectrum analysis of Suspension Bridge and Tied-arch Bridge. The modelling is done using SAP 2000. Response Spectrum analysis is done and the deformation of both the bridges under dead load live load and earthquake load is studied. Axial force, Shear force Moment and Torsion values are observed and studied. Along with earthquake load vehicle load is also applied. According to IRC 006, vehicle loading of class 70R wheeled is applied. Keywords—Suspension Cable Bridge, Tied Arch Bridge, SAP 2000, Response Spectrum Analysis
Implementation of Predicting Student Performance Using Linear Regression Algorithm

Published: June 2022

Abstract: This data approach student achievement in secondary education of two Portuguese schools. The data attributes include student grades, demographic, social and school-related features) and it was collected by using school reports and questionnaires. Two datasets are provided regarding the performance in two distinct subjects: Mathematics (mat) and Portuguese language (por). In [Cortez and Silva, 2008], the two data sets were modeled under binary/five-level classification and regression tasks. Important note: the target attribute G3 has a strong correlation with attributes G2 and G1. This occurs because G3 is the final year grade (issued at the 3rd period), while G1 and G2 correspond to the 1st and 2nd period grades. It is more difficult to predict G3 without G2 and G1, but such prediction is much more useful (see paper source for more details).

Chronic myeloid leukemia (CML) is a rare disease in children and
adolescents and clinical presentations are variable . Symptoms
are often attributable to anemia and splenomegaly. We present a case of
secondary pseudotumor cerebri syndrome as the presenting feature in a
pediatric patient with CML and a review of previous cases. Through these
cases, we discuss this rare but important manifestation of chronic
myeloid leukemia in pediatric CML, its cause and management. We conclude
that pseudotumor cerebri is an important differential diagnosis in these
patients as it may result in permanent visual loss if not addressed

Contributing factors on metabolic mechanism-based CYP3A4-activated/deactivated anticancer drugs: implications for individualizing chemotherapy
Authors: Wang Fengling , Zhang Xue , Lu Huiyu , Meng Xiangyun , Ye Xi , Chen Weidong
Published: June 2022

Cytochrome P450 3A4 (CYP3A4), one of important members of the cytochrome
P450 subfamily, acts as a critical catalyst for multiple drug
metabolism. Pharmacological activities and clinical outcomes of
CYP3A4-metabolized anticancer drugs greatly depend on this enzyme
activity and expression, as it catalyzes a variety of reactions for drug
activation or inactivation. In view of the complex tumor environments as
well as various factors concerning CYP3A4 expression, function, and
regulation such as physiological factors, disease complications,
concomitant drugs, inflammation response and gene polymorphisms, the
pharmacokinetics of most anticancer drugs are influenced by the degree
of induction or inhibition CYP3A4 mediated metabolism. This
inter-individual variability, together with the narrow therapeutic index
of most anticancer drugs, therefore have important implications for
achieving the expected efficacy and minimized toxicity from cancer
chemotherapy in individuals. Goals of the review were to outline and
discuss significant underlying factors that contribute to differences in
drug metabolism in detail, including the expression, activity regulation
and genotype of CYP3A4 in tumor tissues. The purpose is to highlight the
clinically meaningful of CYP3A4 induction or inhibition for metabolic
activation/inactivation-based cancer therapy. Assessing inter-individual
variability of metabolic activity from multiple dimensions will
facilitate the development of robust pharmacokinetics modeling
approaches that may predict an individual’s CYP3A4-activated/deactivated
drug metabolizing capacity and drug response, thereby selecting optimal
treatment regimens.

Risk of skin erosion and local pocket infections in population of patients with cardiac implantable electronic devices undergoing transvenous lead extraction
Authors: Polewczyk Anna , Jacheć Wojciech , Kutarski Andrzej
Published: June 2022

The thinning of the skin over the pocket is an occasional phenomenon in
patients with cardiac implantable electronic devices (CIEDs) most often
associated with the technique of implantation of the device. It is
likely that the thinning of the skin over the generator is a risk factor
for the development of infectious complications in patients with CIED.
Analysis of large database of 3706 patients undergoing transvenous lead
extraction (TLE) showed higher number of points of PADIT score and more
often previous pocket plastic surgery in patients with too shallow
pocket. Most likely, diagnosing only a too shallow CIED pocket is often
an early symptom of infection.
Use of geostatistical models to evaluate landscape and stream network controls on post-fire stream nitrate concentrations
Authors: Rhea Allison E. , Covino Tim , Rhoades Charles C. , Brooks Alexander C.
Published: June 2022

Forested watersheds provide many ecosystem services that have become
increasingly threatened by wildfire. Stream nitrate (NO
) concentrations often increase
following wildfire and can remain elevated for decades. We investigated
the drivers of persistent elevated stream NO in nine watersheds that were burned to varying
degrees 16 years prior by the Hayman fire, Colorado, USA. We evaluated
the ability of multiple linear regression and spatial stream network
modeling approaches to predict observed concentrations of the
biologically active solute NO and
the conservative solute sodium (Na ). Specifically,
we quantified the degree to which landscape and stream network
characteristics predict stream solute concentrations. No landscape
variables were strong predictors of stream Na .
Rather, stream Na variability was largely attributed
to flow-connected spatial autocorrelation, indicating that downstream
hydrologic transport was the primary driver of spatially distributed Na
concentrations. In contrast, vegetation cover,
measured as mean normalized differenced moisture index (NDMI), was the
strongest predictor of spatially distributed stream NO concentrations. Furthermore, stream NO
concentrations had weak
flow-connected spatial autocorrelation and high spatial variability.
This pattern is likely the result of spatially heterogeneous wildfire
behavior that leaves intact forest patches interspersed with high burn
severity patches that are dominated by shrubs and grasses. Post-fire
vegetation also interacts with watershed structure to influence stream
NO patterns. For example, severely
burned convergent hillslopes in headwaters positions were associated
with the highest stream NO
concentrations due to the high proportional influence of hillslope water
in these locations. Our findings suggest that reforestation is critical
for the recovery of stream NO
concentrations to pre-fire levels and targeted planting in severely
burned convergent hillslopes in headwater positions will likely have a
large impact on stream NO
concentrations.

Published: June 2022

Biological soil crust (BSC), as a groundcover, is widely intergrown with
grass. The combined effects of BSC and grass during rainfall on runoff
and sediment yield are still unclear. In this study, simulated rainfall
experiments were applied to a soil flume with four different slope cover
treatments, namely, bare (CK) and Stipa bungeana Train. (STBU),
BSC, and STBU + BSC to observe the processes of runoff and sediment
yield. Additionally, the soil moisture at different depths during
infiltration was observed. The results showed that the runoff generated
by rainfall for all treatments was in the following order:
BSC>STBU+BSC>CK>STBU. Compared
with CK, the STBU promoted infiltration, and BSC and STBU+BSC inhibited
infiltration. The BSCs obviously inhibited infiltration at a depth of 8
cm. As the soil depth increased to 16 cm and 24 cm, the effects of STBU
on promoting infiltration were stronger than those of BSC on inhibiting
infiltration. Compared with the CK, the flow velocity for the BSC, STBU
and STBU + BSC treatments was reduced by 62.79%, 32.27% and 68.29%,
respectively. The BSC and STBU increased the critical shear stress by
increasing the resistance. Additionally, the BSC, STBU and STBU+BSC
treatments reduced the sediment yield rate by 80.8%, 99.8% and 99.9%,
respectively. The soil erosion process was dominated by the soil
detachment capacity in the CK, BSC and STBU+BSC treatments, while the
STBU treatment showed a transport-limited process. This study provided a
scientific basis for the reasonable spatial allocation of vegetation in
arid and semiarid areas and provided a scientific basis for the
correction of vegetation cover factors in soil erosion prediction
models.

Published: June 2022

Engineering support in the field of recognizing Parkinson's disease against the background of other diseases, its progression and monitoring the effectiveness of drugs is currently widely implemented as part of work devoted to the use of re-cording and analysis devices equipped with sensors of movement parameters attached to the patient's body, e.g. accelerometers and gyroscopes. This material touches on an alternative approach, in which the concept of using techniques for processing selected image data obtained during a clinical examination evaluating a patient using the unified UPDRS number scale is proposed. The research was conducted on a material that corresponded to selected components of the scale and included images of faces recorded in the visible light range and images of the outer surfaces of the hand recorded with a thermal imaging camera. This was  aimed at assessing the possibility of differentiating persons in terms of detecting Parkinson's disease on the basis of registered modalities. Thus, tasks aimed at developing characteristics important in the binary classification process were carried out. The assessment of features was made in a modality-dependent manner based on available tools in the field of statistics and machine learning.
Effects of independent magnetic fields in the very low frequency range elf generated by selected elements of an electric traction unit on the ambient environment and electronic systems
Authors: Paś Jacek , Białek Kamil , Wetoszka Patryk
Published: June 2022

The article presents research results and issues related to of magnetic component of electromagnetic field on the environment and electronic systems used in the electric traction unit. The electronic systems used and built into an electric power unit are operated in a wide variety of environmental conditions. Electrical and electronic systems with different purposes coexist on the vast railroad area, and an important operational problem, apart from environmental changes in which these technical objects are operated, is also the issue of external and internal electromagnetic compatibility. Depending on the extent of the railroad area, the intentional or unintentional emission of electromagnetic fields over a range of frequencies, the construction, technical configuration and method of ensuring electromagnetic compatibility for the electrical and electronic systems in use and electronic systems in use are different. It is necessary to skillfully and appropriately use all measures included in the electromagnetic compatibility pyramid to ensure the appropriate level of robustness, immunity and susceptibility of the above mentioned systems. Due to the impact and propagation of electromagnetic waves in the railroad environment, individual frequency bands of interfering signals should be considered separately for the whole spectrum of interfering signals. The article presents the results of research on the generated magnetic fields from the very low frequency (ELF) range by electric power units. Diagnosing the electromagnetic environment over the entire frequency range enables the realization and proper protection of the electrical and electronic systems used in an electric power train from the effects of unintended interference. Knowledge of the parameters of interfering signals - e.g. amplitude, frequency range, spectrum, etc. - will enable designers of electrical and electronic train systems systems to properly protect these facilities from adverse environmental conditions.
A Protection Layer over MapReduce Framework for Big Data Privacy
Authors: Baig Hidayath Ali
Published: June 2022

In many organizations, big data analytics has become a trend in gathering valuable data insights. The framework MapReduce, which is generally used for this purpose, has been accepted by most organizations for its exceptional characteristics. However, because of the availability of significant processing resources, dispersed privacy-sensitive details can be collected quickly, increasing the widespread privacy concerns.  This article reviews some of the existing research articles on the MapReduce framework's privacy issues and proposes an additional layer of privacy protection over the adopted framework. The data is split into bits and processed in the clouds, and two other steps are taken. Hadoop splits the file into bits of a smaller scale. The task tracker then allocates these bits to several mappers. First, the data is split up into key-value pairs, and the intermediate data sets are generated.  The efficiency of the suggested approach may then be effectively interpreted. Overall, the proposed method provides improved scalability. The following figures compare execution time with relation to file size and the number of partitions. As privacy protection technique is used, the loss of data content can be appropriately handled.  It has been demonstrated that MRPL outperforms current methods in terms of CPU optimization, memory usage, and reduced information loss.  Research reveals that the suggested strategy creates significant advantages for Big Data by enhancing privacy and protection. MRPL can considerably solve the privacy issues in Big Data.
Research on identifying psychological health problems of college students by logistic regression model based on data mining
Authors: Chen Qian
Published: June 2022

With the popularisation of education, the number of college students is increasing day by day, and there are also more students with psychological health problems. Whether students’ psychological abnormalities can be detected in time is one of the main problems faced by colleges and universities at present. Adopting digital technology to mine, collect and analyse the data generated by psychological health education in colleges can effectively solve the dynamic development of students’ psychological health problems. Therefore, in this paper, the psychological health problems of college students are identified and classified by establishing an improved logistic regression model. The behaviour characteristics are quantified and the differences are combined according to students’ relationships with their classmates, life rules and economic conditions. The test results show that the regression effect of the model is excellent, which can identify college students’ psychological health problems and improve the intervention and treatment of educators on students’ psychological problems.

Authors: Yan Taohai , Shi Yajing , Cao Shengbin , Zhuang Huimin , Lin Yu , Zhu Lvtao , Lu Dongdong
Published: June 2022

Reinforcement of fibers was carried out by adding carbon black (CB), and hydroxylated and carboxylated carbon nanotubes (CNTs) into electrospinning solution containing doped polyaniline (CSA-PANI) and polyacrylonitrile (PAN). CB/CSA-PANI/PAN and CNT/CSA-PANI/PAN electrospun nanofiber composite membrane was formed in high-voltage electric field. The CSA-PANI/CB/PAN fiber membrane was found to be more brittle than the MWCNTs/CSA-PANI/PAN fiber membrane. The average diameter of the CSA-PANI/CB/PAN nanofibers increased with CB addition, while the average diameter of CNT-added MWCNTs/CSA-PANI/PAN nanofibers decreased with increasing CNT concentrations. Upon greater CB and CNT addition, agglomeration occurred, and the surface of the fibers was raised slightly. The fracture strength of the nanofiber membrane was greatly improved with 1% added CB but then decreased upon further CB addition. Upon addition of CNTs, the fracture strength of the nanofiber membrane first increased and then decreased, and the addition of carboxylated CNTs was more advantageous for improving the fracture strength of the fiber membrane. The electromagnetic shielding performance of the fiber membranes was essentially the same for different radiation frequencies. Upon addition of CB and CNTs, the electromagnetic shielding performance of the fiber first increased and then decreased, with a more pronounced decrease obtained by the addition of CB.
The Occurrence of Stereum hirsutum Associated with Wood Rotting of Olive Trees in Iran
Authors: Peighami Ashnaei Samira , Jafary Hossein , Afshari Azad Homayoun
Published: June 2022

In summer 2021 (June–July), disease symptoms on trunks and shoots were observed in olive groves in the Tarom Sofla region, Qazvin province, Iran. The symptoms were light-pink discoloration and surface depression in the external layers of the wood. As the disease progressed, brown streaks of tissue appeared on the longitudinal sections of the wood. The identification of fungus was made based on PCR amplification of the rDNA-ITS region with the universal fungal primers ITS5 and ITS4. BLAST searches revealed 99.52% identity to Stereum hirsutum. Several species of basidiomycetes are known to live on wood as saprobionts or parasites. On olive trees, they cause white rot symptoms. Although they are not directly responsible for tree mortality; however, they can lead to structural deterioration of woody tissues. To the best of our knowledge, this is the first report of S. hirsutum associated with wood rotting of olive trees in the world.
Better color distribution uniformity and higher luminous intensity for LED by using a three-layered remote phosphor structure
Authors: Loan Nguyen Thi Phuong , Anh Nguyen Doan Quoc , Trang Nguyen Cong , Lee Hsiao-Yi
Published: June 2022

Angular color distribution uniformity has been one of the most relevant properties in the development of white light-emitting diodes (WLEDs), since color consistency and uniformity are crucial factors in quality evaluation of a WLED. Here, particularly considering the need to overcome the poor chromaticity usually associated with WLED, we introduce a new design for the remote-phosphor package, namely a three-layered or triple-layer (TL) phosphor structure. Using three phosphor layers in packaging a WLED can result in higher color quality and luminous efficacy, compared to the double-layer (DL) configuration. In the present study, the results of using three remote phosphor layers indicate that although the structure using three layers has a lower color rendering index, the color quality scale is better than that available from the package with two layers. Additionally, the color-deviation values in the TL structure are smaller than in the dual-layer one, especially at high color temperatures (7,700 K and 8,500 K). Besides, in comparison with the DL model, the TL package increases the luminous flux by 1.4%–2%. Therefore, the TL remote phosphor structure possesses the greatest potential in enhancing the WLED quality.
Effect of electron beam irradiation on filtering facepiece respirators integrity and filtering efficiency
Authors: Chmielewska Dagmara , Werner Łukasz , Gryczka Urszula , Migdał Wojciech
Published: June 2022

The outbreak of the COVID-19 pandemic has shown that the demand for medical masks and respirators exceeds the current global stockpile of these items, and there is a dire need to increase the production capacity. Considering that ionizing radiation has been used for sterilization of medical products for many years and electron beam (EB) irradiation enables the treatment of huge quantities of disposable medical products in a short time this method should be tested for the mask’s decontamination. In this work, three different filtering facepiece respirators (FFRs) were irradiated with electron beams of 12 kGy and 25 kGy. The results confirmed that the decrease in filtration efficiency after irradiation of all respirators results from the elimination of the electric charge from the polypropylene (PP) fibers in the irradiation process. Moreover, the applied doses may affect the thermal stability of PP fabrics, while filtering materials structure and integrity have not changed after irradiation.
Genesis of evaluation theory, connection with value theory
Authors: Yurak Vera Vasilievna
Published: June 2022

In the development of evaluation theory, there is a trend of gradual complication through the emergence of new evaluation paradigms, approaches and methods, which proves the constant development of the evaluation theory and its relevance. However, evaluation theory is still full of many unresolved problems. These problems are basically related to the lack of a well-built theoretical framework for evaluation, based on fundamental research on the genesis and evolution of the evaluation theory coupled with the value theory. The purpose of the study is to study the genesis of the evaluation theory in conjunction with the development of the value theory, and the structure of assessment. As a result, It has revealed that the evaluation has a social nature and arose with the emergence of man on Earth; The embryonic genesis, as a theory, was in Antiquity, but the academic evaluation theory was formed only in the 30s of the XX century in economic research. Since the 20th century, there has been a trend of shifting priorities from the value theory to the procedure for evaluating the value, contributing to the emergence of a separate profession of an appraiser. The problem of subjectivization of both the evaluating process and the results of it has been established. The basic structure of the evaluation has been determined. Paper reveals the fact of the complication of the evaluation structure by identifying one more subject of evaluation. The conflict-nature of the evaluation is identified.

Authors: Dmitrieva Yulia Viktorovna
Published: June 2022

The purpose of the study is to assess the phenomenon of longevity as a particularly important component in the study of increasing life expectancy and reducing mortality. The article reveals the possibilities of increasing life expectancy and reducing mortality through research in the field of the phenomenon of longevity, self-preservation behavior and social information systems. The scientific novelty lies in substantiating the possibilities of changing demographic behavior through the prism of the study of longevity as a kind of model of natural physiological aging of the population, as well as using the system of social "programming" of the population as a special social management tool. As a result of the study, unique opportunities for changing the demographic behavior of the population have been identified, which should be used in the development of practical measures for the implementation of social and demographic policy.

Several programs in Merdeka Belajar Kampus Merdeka (MBKM) Program include industrial internships, independent projects, student exchanges, community service projects, humanitarian programs, and so on. Kampus Mengajar 2 is one of the programs that hadbeen running. The program received various responses from the public, which were expressed on social media. The Supervisor at kampus mengajar 2 was also active in providing various comments on the kampus mengajar 2 telegramgroups in the form of good, bad, and neutral comments. These comments have the potential to generate a growing sentiment among the general public and academics. Based on these issues, the researcher analyzed the kampus mengajar 2 sentiments toward the implementation of the Merdeka Belajar Kampus Merdeka program with the data source being comments on the supervisors' telegram group. The data obtained from the telegram group is classified as good, bad, or neutral using the Naive Bayes method and K-Nearest Neighbors on up to 591 data points. The data is then divided into two parts: training data and testing data. Testing data can account for up to 20 percent of total data, with the remaining 80 percent serving as training data. The accuracy results on sentiment analysis show that the Naive Bayes method outperforms the KNN method, with 99.30 percent for Naive Bayes and 97.20 percent for K-Nearest Neighbors

The aims of this study to examine the use of durian seed flour in rations on fermentability and digestibility in beef cattle fattening rations. The study was conducted experimentally with 5 treatments of durian flour: 0, 8, 16, 24, and 32% and each treatment carried out 4 replications. In vitro technique was used to evaluate the fermentability and digestibility of the diet. The data were analyzed by the ANOVA test, the relationship between treatment and variables was analyzed by regression and correlation, while the relationship between variables was tested by Pearson Product Moment Correlation. The results showed that the higher the use of durian seeds decreased the lower (P<0.05) the content of volatile fatty acids (ALT), ammonia, dry matter digestibility (KCBK), and organic matter digestibility (KCBO). This pattern is indicated by a negative linear regression with a very strong correlation level (r) >80. Although there was a decrease, the use of durian seed flour at a level of 16% produced ALT, ammonia, KCBK, and KCBO respectively 141.38 mM, 3.74 mM, 60.46%, and 68.28%. The results showed that there was a relationship between KCBK and KCBO on ALT and ammonia which was very significant (P<0.01) and very strong (r>0.80), so it can be concluded that the use of 16% durian seeds gave the best results. Durian seeds have the potential to be used as a mixture of cow feed.
