Comparative evaluation of two prophylactic intravenous bolus doses of phenylephrine for prevention of spinal-induced hypotension in elective cesarean sections: a prospective and randomized study
No full textBackground: Hypotension is a common and clinically significant complication associated with spinal anesthesia during cesarean section, often persisting despite standard preventive strategies such as fluid preloading and left uterine displacement. Vasopressors like phenylephrine are routinely employed to counteract the hemodynamic instability, yet limited data exist comparing different fixed bolus doses of phenylephrine for prophylaxis against spinal-induced hypotension in obstetric anesthesia. This study aimed to evaluate and compare the efficacy and safety of two intravenous bolus doses of phenylephrine-150 micrograms and 200 micrograms-administered immediately following spinal anesthesia, in preventing maternal hypotension during cesarean delivery.
Methods: A prospective, randomized, double-blind study was conducted at Adichunchanagiri Institute of Medical Sciences, Karnataka, India involving 60 parturients scheduled for elective cesarean section. Group A received 150 µg and group B received 200 µg phenylephrine IV bolus immediately after spinal anesthesia. Hemodynamic parameters, incidence of hypotension and bradycardia, requirement of rescue boluses, and Apgar scores were recorded.Results: The incidence of hypotension was 16.6% in both groups. Group B showed a significantly higher incidence of bradycardia (43.3%) compared to group A (20%, p<0.05). Group A demonstrated better hemodynamic stability with fewer rescue interventions. Neonatal outcomes were similar in both groups.
Conclusions: A 150 µg bolus of phenylephrine is as effective as 200 µg in preventing hypotension following spinal anesthesia in cesarean delivery, with fewer adverse effects. It is recommended as the preferred dose for prophylaxis
Achieving 100% roof-top based PV penetration in a low voltage distribution network
No full textGiven the merits of photovoltaic technology (PV), rooftop PV systems are becoming more prevalent in residential and commercial areas. As a result of the growing number of photovoltaic systems connected to low voltage (LV) distribution grids, a significant portion of power flow from photovoltaic arrays to the LV grid, As the PV penetration increases, this effect becomes more severe. This reversal of power flow (from the load side to the grid side) results in a voltage rise problem along the distribution feeder. Such an issue is more pronounced near the point of common coupling (PCC). Overvoltages are not desired as they can damage consumers’ electronic devices, burn the insulation and can trip protective equipment, causing sudden power outages. The principal objective of this study is to achieve 100% PV penetration in a low voltage distribution network while maintaining voltages within the grid constraints by employing numerous voltage control techniques. To conduct PV penetration studies, the European low-voltage distribution benchmark network developed by CIGRE is selected. PV systems of various configurations are designed and integrated into the CIGRE LV network. The results of the PV penetration analysis on the CIGRE network suggest that with the increase in the distance between the source and the load, the penetration level decreases drastically. The worst-case network model in which the penetration level is reduced to 65% is selected for employing voltage control strategies. Two main strategies have been used to improve PV penetration. In the first category of methods, the reactive power is controlled by the PV system so that voltages at the PCCs are within the grid voltage limits. Four different reactive power control methods are employed. The second category of methods are based on active power control, in which the voltages are controlled by batteries/electrolyzers by absorbing excess power generated by the PV system, avoiding reverse power flow into the grid. The results obtained reveal that all the techniques employed are successful at increasing PV penetration to 100% without violating grid voltage limits. However, it is concluded that, batteries/electrolyzer systems provide better value in terms of effectiveness in solving the voltage rise issue. They also offers lower losses, and multiple-use cases.Electrical Engineering | Sustainable Energy Technolog

Instrumented Hip Implant: A Review
No full textAbout 20% of people older than forty years old face more bone degenerative diseases. The older population is increasing quite rapidly than before which increases the need for knee or hip implants tremendously. One of the major problems of the current implants is their short lifetime and their impact on the surrounding human tissue. The short life can be attributed to implant wear, loosening, and misalignment, which often cause pain and discomfort to the patient. Functional failure of the implant may be followed by a revision surgery, which is often painful and has a relatively low success rate. Moreover, to avoid unexpected failure and unnoticed deterioration of the implant, it is important to make provision for monitoring implants' performance. Instrumented implants can provide accurate monitoring of the loosening state of the implant, which can delay the revision surgeries and its consequences. This study provides a comprehensive review of the technological development of instrumented hip implants to monitor the status of the implants. The main requirements for the implants are highlighted by reviewing different aspects of the instrumented hip implant systems. In-vivo studies reported in the literature were summarized. Vibration and Acoustic Emission (AE) measurement based loosening detection were found to be the most common methods for in-vitro studies. A comprehensive review of power supply and communication modules was presented. Despite the advancement in this field, current systems are not yet able to provide effective monitoring of the implant's status during the daily activities of patients. 2001-2012 IEEE.Manuscript received November 24, 2020; accepted December 10, 2020.

Normal Probability and Heuristics based Path Planning and Navigation System for Mapped Roads
No full textAbstractIn a hybrid road network with multiple paths to same location having prior geographical knowledge, successful navigation for mobile robots is one of the main challenges. Path planning is one of the most important issues in the navigation process which enables the selection and identification of a suitable path for the robot to traverse in the workspace area. Path-planning for mapped roads can be considered as the process of navigating a mobile robot around a configured road map, which provides optimized path by considering roughness of roads. In this paper, we propose a novel navigation algorithm for outdoor environments, which permits robots to travel from one static node to another along a planned path. It utilizes Normal probability weight distribution (NPWD) to assign weights between two nodes dynamically. Heuristics based shortest path (HSP) algorithm is employed to solve complex optimization problems concerned with real-world scenarios. The experiments performed on categorized road databases show significant improvement in timings and complexity of system. Our results justify the effectiveness for the implementation of driver-assist system
Development of Smart Squeeze Film Dampers for Small Rotors
No full textAbstractSqueeze film dampers (SFD) are lubrication elements which provide viscous damping in rotating systems. Squeeze film dampers in rotating machinery provide structural isolation, reduce the amplitudes of rotor response to unbalance and also assist to suppress rotor dynamic instability. They have been long used to subdue instability and vibration issues that are difficult to solve using conventional bearings like journal or ball bearings. Numerous studies have been tried to produce mechanically tunable dampers which allow the damping to be changed during different mode of operation. Magneto-rheological (MR) fluids are one of the strong contenders for tunable dampers. They provide the possibility to control the dynamic characteristics of conventional fluid dampers. Magneto-rheological fluids are viscous fluids suspended with micron sized ferromagnetic particles which on application of magnetic field undergo changes in their physical and mechanical properties like viscosity, stiffness, etc. This characteristic can be used to build squeeze film damper whose damping properties will change based on the input force. In present work a typical SFD is designed and development using MR fluid and tested for different amount of damping. It is observed that the damping provided by MR fluid increases with increase in magnetic field and the amplitude of vibration reduces by 70% at critical speeds

Dentro del campo de la historia y la antropología, resulta de interés el estudio del origen de dichos envases, mejor conocidos como oliveras o botijas, que al principio fueron destinados al comercio transoceánico desde los siglos XVI al XIX y posteriormente con otros fines. Tal es el caso del uso documentado de botijas ibéricas en ceremonias nupciales en la comunidad de Xalitla y en otras localidades balsenses, donde su función primaria como contenedor de líquidos no ha cambiado a lo largo del tiempo, sino que adquirió un nuevo uso social, en este caso, relacionado con actividades rituales performativas.After the early years following the discovery of the Americas, the Spanish Crown promoted expanding and ongoing trade with the New World. Many of these commercial products were transported across the Atlantic in pottery vessels to meet the demands of Spaniards and their descendants as colonial society grew. In history and anthropology, there is an interest in studying the origin of such earthenware jugs, better known as olive jars or botijas, which were originally intended for sixteenth- to eighteenth-century transoceanic trade and later for other purposes. This is the case of the documented use of Iberian botijas in nuptial ceremonies in the community of Xalitla and other towns in the Balsas region of the state of Guerrero, where their primary function as containers for liquids has not changed through time, but has acquired a new social use related to ritual performances
