A comparative study of spontaneous versus induced labor in primi and multiparous women at tertiary care centre

Background: Objectives of the study were to compare progression of spontaneous versus induced labor in primigravida and multigravida women.Methods: Pregnant women admitted in labor room of RNT medical college Udaipur during January 2021 to June 2021 were selected for this study. A total of 200 pregnant women were selected and divided into two groups. Women in group A were induced while in group B were women with spontaneous onset of labour. Labor progression in both was compared.Results: In group A, the mean duration of active phase in primigravida was 4.08+2.30 hr. In group A, the mean duration of the second stage in a primigravida was 25.5+8.15 min and in a multigravida was 17.38+9.95 min. In group B,the mean duration of second stage in a primigravida was 41.3+9.6 min, while in a multigravida was 22.72+6.2h. The mean duration of active phase in group A in the primigravida and multigravida was almost similar, showing that induction does not have any effect on the duration of active phase. The mean duration of the second stage of group A in primigravida was 25 min and multigravida were 17 min showing that induction reduces the duration of the second stage.Conclusions: Induction of labor when done at the right gestational age for correct indication is beneficial to women as it reduces the complications caused due to the continuation of high-risk pregnancies

Design of Space Efficient Electric Vehicle Charging Infrastructure Integration Impact on Power Grid Network

With an ever-increasing number of electric vehicles (EVs) on the roads, there is a high demand for EV charging infrastructure. The present charging infrastructure in the market requires a lot of space and sometimes leads to traffic congestion, increasing the risk of accidents and obstruction of emergency vehicles. As the current infrastructure requires ample space, the cost of setting up this charging infrastructure becomes very high in metropolitan cities. In addition, there are a lot of adverse effects on the power grid due to the integration of EVs. This paper discusses a space-efficient charging infrastructure and multi-agent system-based power grid balance to overcome these issues. The proposed multi-level EV charging station can save a lot of space and reduce traffic congestion as more vehicles can be accommodated in the space. Depending on the size, capacity, and type of multi-level vehicle charging system, it can serve as a reliable charging solution at sites with medium and high daily footfall. We integrated the EV charging station with IEEE 33 bus test system and analyzed the grid and charging stations. The proposed scheme is exhaustively tested by simulation in a discrete-time event simulator in MATLAB and analyzed with varying EV arrival rates, time periods, etc

Performance Analysis of a Cooperative MAC Protocol of Wireless Ad Hoc Networks

Different medium access control (MAC) layer protocols, for example, IEEE 802.11 series and others are used in wireless local area networks. They have limitation in handling bulk data transfer applications, like video-on-demand, videoconference, etc. To avoid this problem a cooperative MAC protocol environment has been introduced, which enables the MAC protocol of a node to use its nearby nodes MAC protocol as and when required. We have found on various occasions that specified cooperative MAC establishes cooperative transmissions to send the specified data to the destination. In this paper we propose cooperative MAC priority (CoopMACPri) protocol which exploits the advantages of priority value given by the upper layers for selection of different paths to nodes running heterogeneous applications in a wireless ad hoc network environment. The CoopMACPri protocol improves the system throughput and minimizes energy consumption. Using a Markov chain model, we developed a model to analyse the performance of CoopMACPri protocol; and also derived closed-form expression of saturated system throughput and energy consumption. Performance evaluations validate the accuracy of the theoretical analysis, and also show that the performance of CoopMACPri protocol varies with the number of nodes. We observed that the simulation results and analysis reflects the effectiveness of the proposed protocol as per the specifications

Evaluation of shear bond strength of acrylic denture teeth to heat polymerized denture base resin after different surface treatments on the bonding surface of acrylic denture teeth - an in vitro study

Present study aimed to improve the bond strength of denture teeth to acrylic resin denture base by chemical or mechanical modification on the bonding surface of denture teeth. Total 40 artificial acrylic resin central incisors and lateral incisors were divided into five groups: group I, 8 samples without modification (control group); group II, 8 samples (bonding surface of teeth were treated with monomer); group III, 8 samples (bonding surface of teeth were treated with monomer and the glaze layer removed with aluminum oxide stone bur); group IV, 8 samples (bonding surface of teeth were treated with acetone); and group V, 8 samples (acetone application followed by glaze layer removed with aluminum oxide stone bonding surface of acrylic resin teeth). They were mounted on wax blocks, and the blocks were acrylized. The bond strength values were obtained by subjecting the samples to shear compressive load under universal testing machine. The results were subjected to statistical analysis. The mean value of bond strength was highest for group E (modified by aluminum oxide abrasion prior to dichloromethane application), followed by group C (modified by aluminum oxide abrasion prior to monomer application), group D (modified by dichloromethane application), group B (modified by monomer application)

ANN-based structure peciliaties evaluation of polymer composite reinforced with unidirectional carbon fiber

At the moment, there is a growing interest in composite materials with matrices based on thermoplastic polymers; these materials are superior to traditional carbon fiber plastics due to higher fracture toughness and impact strength, low smoke generation during combustion, and high thermal and chemical resistance. The deformation behavior of such composite materials due to the high plastic deformation of the matrix differs from the behavior of traditional composites, which must be considered when performing calculations. In our study, as a model object, the features of the microstructure of single carbon thread impregnated with polysulfone were studied in order to evaluate the distribution of misorientation angles of elementary fibers, the degree of their damage, the thickness of the polymer matrix interlayers between elementary fibers in threads impregnated with more viscous thermoplastic binders. Statistical analysis of a large array of micrographs was carried out using specially developed algorithms for computer processing of electron microscopic images of a composite material. Algorithms for processing arrays of images using machine vision algorithms are proposed. Based on the analysis of the data array, the distributions of carbon fibers impregnated with polysulfone were plotted over the misorientation angle of the filaments and over the interfilament distance in the longitudinal and cross sections of the fiber. Using the machine learning method, an algorithm for detecting violations of the filament structure was implemented. The data obtained can be used to refine the calculations of the strength and deformation characteristics of composite materials with thermoplastic matrices

Distribution of CC-chemokine receptor-5-∆32 allele among the tribal and caste population of Vidarbha region of Maharashtra state

Background: Genetic relationships among the ethnic groups are not uniform across the geographical region. Considering this assumption, we analyzed the frequency of the CC-chemokine receptor-5 (CCR5)-∆32 allele of the CCR5 chemokine receptor, which is considered a Caucasian marker, in Bhil tribal and Brahmin caste sample sets from the population. Materials and Methods: 108 blood samples were collected from 6 tribe′s populations and a caste population from the district of Vidarbha region. Results and Discussion: The presence of low frequencies of CCR5-Δ32 in an individual of Bhil tribe (0.034, χ2 value 0.017) in the present study implies that these communities may have a better resistance toward human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) than the other studied tribe sample, as non-show such mutation. Conclusion: The marginal presence of the allele seen in the studied tribal population could be due to gene flow from the people of European descent. However, lack of the homozygous CCR5-Δ32 mutation and the low prevalence of heterozygous CCR5-Δ32 mutations suggest that the Indians are highly susceptible to HIV/AIDS, and this correlates with the highest number of HIV/AIDS infected individuals in India
