Abstract
Aim:
To compare and evaluate the effect of glide path creation with Nitiflex hand K- file, Proglider and Path file on canal transportation and concentricity in apically curved canals.
Objectives:
To compare the degree of canal transportation and concentricity between:
1) Glide path preparation with Nitiflex hand-K file vs Proglider file followed by combination of Hyflex EDM and CM file instrumentation
2) Glide path preparation with Proglider file vs Path file followed by combination of Hyflex EDM and CM file instrumentation
3) Glide path preparation with Nitiflex hand- K file vs Path file followed by combination of Hyflex EDM and CM file instrumentation
Materials and methods:
Forty ISO 20, 0.02 taper, Endo Training Blocks (Dentsply Maillefer) were acquired and divided into following four groups (n = 10): group A, Control group without glide path preparation; group B, Glide path preparation with Nitiflex hand-K file; Group C: Glide path preparation with Proglider file; Group D: Glide path preparation with Path files. In all the groups, combination of Hyflex EDM and CM file instrumentation was done after glide path creation. Pre- and post-instrumentation digital images were processed with Image J Version 1.8.0 software to identify the center of the canal, and then superimposed using Adobe Photoshop 7.0 software. Unpaired/independent t test and One Way ANOVA were used for intergroup comparison of difference of mean scores.
Results:
In comparison to other groups, training blocks instrumented with Proglider files and a combination of Hyflex EDM and CM files had reduced deviation in canal axis.
Conclusion:
Following the combination of Hyflex EDM and CM file instrumentation with an earlier glide path created with Proglider file, canal concentricity and canal geometry are better preserved.

Treatment of mandibular Grade II furcation defects using demineralized freeze-dried bone allograft alone or in combination with guided tissue regeneration membrane – A randomized controlled clinical trial.
Authors: Sudha Swati  , Gupta Ira , Sarkar Saranik 
Published: July 2023

Background– Periodontal disease, if not interfered, will headway further with attachment loss involving the bifurcation or trifurcation of multirooted teeth. Furcation involved molar teeth respond less favorably to conventional periodontal therapy alone resulting into tooth loss. Combining osseous grafting with guided tissue regeneration membrane may enhance the response to treatment as compared to graft – only therapy by achieving mechanical stabilization and preventing micromovement of the bone graft material.

Aim & Objective – To compare the efficacy of demineralized freeze-dried bone allograft alone or in combination with guided tissue regeneration membrane in the treatment of mandibular Grade II furcation defects.

Materials & method - In this study a total number of 20 patients with 20 mandibular sites (buccal grade II furcation involvement) were evaluated. They were divided into two groups: Control group (bone graft only) and test group (bone graft + GTR). The clinical parameters assessed were vertical probing depth, horizontal probing depth and relative clinical attachment level.

Results – In this study the statistical analyses comparing test and control sites at baseline revealed no significant differences between the two groups for any of the clinical parameters considered. At 6 month evaluation, significant difference was found between two groups regarding VPD, HPD and rCAL.

Conclusion – It was concluded that there is a significant enhanced effect of using DFDBA bone graft in combination with GTR membrane over bone graft alone for the treatment of mandibular Grade II furcation defects.
Prevention and Management of Denture Stomatitis
Authors: Akhil Pankhuri 
Published: July 2023

Denture stomatitis, also called as Chronic Atrophic Candidiasis, is considered to be synonymous with the condition better known as denture sore mouth, a diffuse erythema and edema of the denture bearing area, often occurring with angular chelitis. It is the most common form of the oral disease. The prevalence of denture related mucosal lesions (DMLS) were observed more frequently in complete denture wearers than in partial denture wearers as the area covered by a complete denture is more and therefore increase the risk of DMLS. It is associated with dental plaque, candida infection, poor denture retention and mechanical trauma1. The major risk factor for the development of this condition is wearing an upper complete denture, particularly when it is not removed during sleep and cleaned regularly. Older dentures are more likely to be involved. Other factors include xerostomia (dry mouth), diabetes or a high carbohydrate diet, human immunodeficiency virus (HIV).

Published: July 2023

Purpose- To assess the growth status of adolescents by cervical vertebra maturity indicators (CVMI) and its correlation with the level of serum alkaline phosphatase (ALP) and also to evaluate the diagnostic importance of serum alkaline phosphatase as an indicator of skeletal maturation.
Settings and Design: prospective cross sectional observational study

Methods and Materials - 150 subjects (75 males and 75 females) were selected in the age group 6-17 years of age.The study sample was distributed into three groups based on chronological age Group-I(Pre- Pubertal) consisting of sample between 6-9 yrs, Group-II(Pubertal) between 10-13 yrs & Group-III (Post- Pubertal)14-17yrs of age, with each group containing 25 males and females each. To appraise the cervical vertebral development by Hassel and Farman method lateral cephalograms were taken in natural head position. To evaluate the serum Alkaline phosphatase levels 2 ml of venous blood sample was collected and was subjected to biochemical assessment.
Statistical analysis used: paired sample T test, Pearson Correlation Coefficient , ANOVA analysis

Results- The mean alkaline phosphatase levels were evaluated in each group, Group II (Pubertal) had the highest alkaline phosphatase level which was statistically significant among all groups. The correlation between alkaline phosphatase and CVMI was assessed using Pearson Correlation Coefficient. A significant negative correlation between the two entities was found (r =-0.630, p<0.001). On evaluating the CVMI stages and alkaline phosphatase levels individually in males and females, males had higher levels which were statistically significant.
Conclusions-The study demonstrates age trends in the level of serum alkaline phosphatase levels that may be used to evaluate the skeletal maturation. The levels in males were higher than females which also are of diagnostic importance.

For a research problem: as a single-diode model (electrical circuit) is difficult to discover the precise answer to employing analytical approaches, develop and compute the electrical parameters of the PV cell roughly using numerical algorithms. Therefore, the goal of this work is to create an algorithm that aids in the approximate solution of the electrical parameters of solar cells. Three methods have been proposed for these calculations, each of which has a quicker calculation time and a higher level of accuracy.
By streamlining the calculation process, the proposed method solves the problems of complexity and precision. The I-V and P-V characteristic curves of solar cells can then be utilized to compare the efficacy of the tested methods. In addition, the analysis of root mean square error indicates that the proposed method is more applicable than alternative methods. In fact, this extraction procedure can be regarded as an efficient and precise method for estimating the single diode model parameters of solar cells.
The results indicate that this precise and effective strategy can play an important role in the retrieval of single diode model parameters. In fact, the method proposed in this paper makes numerically implementing parameter models in technology simpler. In addition, it provides an optimization suggestion for the production of solar cells

Published: July 2023

In the context of the "4 th industrial revolution" that is taking shape, people with certain knowledge, experience and ecological culture are more actively involved in individual and collective decision-making to overcome various environmental problems. One of these environmental problems is the acoustic noise of the environment. Today, many citizens are wondering: what is the level of acoustic noise pollution in the place where I live, work, study or stay and whether it meets the standards. Is this sound level harmful to my health? To answer these questions, many international and national standards and other regulatory documents have been developed. However, these documents are complex, require the use of expensive equipment, i.e. inaccessible to ordinary citizens. On the other hand, the computational, communication and sensory capabilities of modern mobile phones allow them to measure noise performance in order to conduct noise monitoring. To do this, citizens need simple and clear methods, methodologies, instructions for assessing the noise situation in a certain area and creating noise maps using these measurements. The article attempts to develop a simplified methodology for conducting noise monitoring for citizens using their mobile phones. Also, for clarity of the process, monitoring experiments were carried out with mobile phones and professional sound level meters, in order to assess the harmful effects of traffic noise (B. Vahabzade Avenue) on an educational institution (Baku State University – BSU) and research activities (Institute Information Technology-IIT).
In preparing the article, general scientific methods and methodologies were used, such as analysis and synthesis, comparison, generalization, and a systematic approach.
Citizens can use the survey results to identify areas of noise discomfort using their mobile phones

Published: July 2023

Abstract
Maintaining a constant flow in a potable water distribution hydraulic system is challenging due to fluctuations caused by changes in user demand and seasonal factors. This study aimed to calculate the coefficients and curves of hourly and daily variation of water demand in the water distribution system of Chihuahua. It is crucial to understand the hydraulic system's behavior during peak demands and assess its capacity. The methodology involved calculating coefficients and curves of variation of demand based on flow data measured at the inlet of various hydrometric sectors using flanged electromagnetic flowmeters of various diameters and models. The results showed that the variation curves and coefficients of water demand are valuable tools for modeling, designing, and operating water networks. Incorporating these curves into hydraulic simulations during the planning and design stage can improve the accuracy of these models and better reflect the network's actual behavior. The proposed method is suitable for application in cities with similar demographic and social characteristics. The study concludes that accurate supply area information for hydrometric sectors is essential in constructing the curves and coefficients of demand variation, which can lead to opportunities for improving water service by informing more effective network design and operation.

Published: July 2023

Abstract
To date, few systematic studies have been conducted of the spatial distribution, formation mechanism, and health risks of high-fluoride (F−) shallow groundwater in humid and semi-humid areas of the Xikuangshan antimony mine, Hunan Province, China. In this study, during March and April 2022, a total of 39 shallow groundwater samples were collected and analyzed using factor analysis, principal component analysis, and health risk assessment. F− concentrations in the shallow groundwater were found in the range of 0.08–15.00 mg/L (mean: 1.21 mg/L), with 25.64% of the samples having F− concentrations higher than in the Chinese national standard for drinking water (1.00 mg/L). Principal component analysis revealed that the main source of F− in the shallow groundwater samples is cation exchange, accounting for 73.40%, followed by the dissolution and precipitation of F-bearing minerals (15.10%) and human influence (11.50%). Among different age groups, children had the highest percentage of individuals (36.38%) with an F− intake above the health risk quotient safety limit, followed by adult males (23.12%), teenagers (22.21%), and infants (21.22%). The findings of this study will contribute to devising strategies for the provision of safe drinking water and the management of the geological environment.

Published: July 2023

Abstract

Sediment accumulation in combined sewers can induce blockage and odor problems. Among various cleaning methods, using self-cleaning device-generated flushing waves has been thought to be an effective solution. In this study, a series of numerical tests were conducted using CFD software to investigate the cleaning efficiency of deposited sediment particles based on a simplified self-cleaning device. The CFD model was validated by the experimental and numerical results in the literature. The effects of several parameters including the flushing gate height, sediment bed thickness, sediment bed length, and sediment bed position on cleaning efficiency were discussed. A relative accumulative transport rate was defined to analyze the cleaning efficiency. Results showed that the lowest height of the flushing gate had the best effects on sediment removal. The flushing waves generated from the sudden opening of the flushing gate were capable of cleaning sediment deposits in the given initial sediment bed thickness, length, and position. The required time duration for cleaning the sediment deposit completely increased about 6, 3, and 3 times when the sediment bed thickness, sediment bed length, and distance between the flushing gate and sediment bed increased 10, 4, and 7 times, respectively.

Published: July 2023

Introduction. The article presents an overview of the author's original works devoted to identifying the regulatory mechanisms of the emotional sphere using an innovative approach. The problem of self-organization of mental activity, connected with the determination of the system’s state and the assessment of its stability, is discussed.
Methods. The research program included the author's model of qualitative assessment of mimic response patterns. To quantitatively assess the state of the system by the tension of the facial muscles, an analytical apparatus was developed based on the matrix method, as well as stability criteria and other indicators for assessing the state of the emotional regulation system.
Results. The main results were obtained on subjects with epilepsy. During diagnostic tests using the myographic measurement of facial muscle tone during the experience and perception of basic emotions, signs of their blocking were revealed. A comparative analysis of individual clinical groups made it possible to determine the significance of various limitations of emotions that manifest themselves at the level of reverse afferentation of the emotional regulation system.
Discussion. Comparative analysis of the data of qualitative and quantitative analysis made it possible to reveal patterns of regulatory mechanisms associated with distorted afferentation of basic emotions.

Published: July 2023

Background:
The words "nutrition" and "pharmaceutical" are combined to form the
phrase "nutraceutical." Nutraceuticals are foods or dietary components that have an important role
in regulating and sustaining normal physiological function in humans. For the treatment of dysmenorrhoea,
a variety of pharmacological medications are available, however, they all have significant
side effects. Dietary supplements and lifestyle management, on the other hand, were found to have a
major influence on the occurrence and control of dysmenorrhea.

Objective:
The objective of this paper is to study a comprehensive review of the dietary and nutritional
supplements with special emphasis on dysmenorrhea. This paper focuses on understanding
and interpreting the details of menstrual pain and its effective nutritional diet that can be used as a
treatment for avoiding menstrual discomfort.

Methods:
The selection of data has been done by studying a combination of various research and
review papers from different databases like PubMed, NCBI, Science Direct, WHO, Cochrane Library,
and Web of Science from the year 2000-2022.

Results:
Based on various papers and literature reviews, we have concluded about various dietary
supplements and herbs that can be used to avoid pain during mensuration followed by its all-daily
requirement of nutrition on different age groups and efficacy of treatments.

Conclusion:
According to current evidence, young women should be instructed in the proper use of
dietary supplements, nutrition, and vitamins, as well as the inclusion of effective diet and lifestyle
changes such as exercise and a well-balanced diet with adequate nutrition, as these are likely to
reduce the negative effects of dysmenorrhea.
Study on CLLC-SMES System based on the Passivity Control Strategy
Authors: Ye Tengfei , Chen Xiaoqiang , Wang Zhongxian 
Published: July 2023

Background:
SMES systems as power compensation devices can effectively improve
the transient stability of the power system. Due to the nonlinear and strongly coupled characteristics
of the compensation device, an effective transfer function cannot be established, such that
the traditional PI control by the linearization cannot accurately describe the complex nonlinear
system.

Objective:
In this paper, a passive control strategy is introduced for the SMES System based on
CLLC resonant converter to solve the problems that the traditional PI control cannot accurately
describe the complex nonlinear system and the parameters’ settings are complicated.

Methods:
First, according to KVL and KCL, the mathematical model of the SMES system
based on the CLLC resonant converter in the (d, q) coordinates is derived and established. Second,
based on passive control theory, the port-controlled dissipation Hamiltonian model of
CLLC-SMES is given. Third, combined with the passivity of SMES, the energy equation is established
and the active and reactive power are analyzed respectively for the balanceable expectation,
and then the energy equation is solved to obtain the drive signal of the switch tube.
Fourth, the stability of the passive controller is verified by the Lyapunov equation, and the feasibility
of the passive control strategy of CLLC-SMES is verified by simulation.

Results:
The results show that compared with the traditional PI control strategy, the power
compensation system based on the passive control strategy does not need to establish the transfer
function and the parameters are simple to adjust.

Conclusion:
It can not only track the active and reactive power commands quickly and accurately
but also improve the transient state of the power system effectively.
