BACKGROUND In this study we wanted to compare the clinical outcomes in terms of symptom improvement and perioperative results of monopolar and bipolar trans urethral resection of prostrate (TURP) for benign prostatic hyperplasia (BPH) and evaluate the advantages of bipolar transurethral resection over the monopolar resection. METHODS A total of 150 patients who underwent trans urethral resection of prostate (TURP) surgical procedure, (n = 75 for monopolar TURP) and (n = 75 for bipolar TURP) for BPH enrolled between December 2018 to November 2020 at the Department of Urology in VSSIMSAR, Burla,

Summary: Differentiating dipoles (tangential generators) from monopoles (radial generators) in routine EEG reading can be difficult. The polarity of sharp waves seen on surface EEG will change depending on the generator being located at the wall of the sulcus versus the crown of a gyrus. In this article, the authors introduce visual rules that may be used to determine polarity and estimate the localization of potentials during analysis of the EEG.

Abstract. Most of the high-altitude auroral electric fields observed by CLUSTER can be classified into monopolar and bipolar structures. The observations associate monopolar electric fields with polar cap boundary arcs, while bipolar fields tend to be linked to discrete arcs within the auroral oval and to polar cap arcs. The present paper proposes an explanation for this association based on a simple model of the magnetotail configuration and kinetic model computations.

<strong>Background</strong><strong>:</strong> Endoscopic procedures like Trans urethral resection of prostate are scarless surgeries for benign prostatic hyperplasia, and unlike any other surgery, it has its ups and downs. Monopolar-TURP has been the standard of treatment for BPH but over time there has been a shift towards Bipolar-TURP. <strong>Methods: </strong>The present study is undertaken to study and compare postoperative outcomes after monopolar and bipolar transurethral prostate resection. An ambispectrive observational study was conducted on 68 patients who underwent t

Purpose: Today radiofrequency heart ablation is gold standard for the radical surgical treatment of different types of heart rhythm disturbances.The purpose of the research is a comparative analysis of monopolar and bipolar electrodes for ablation during open heart surgery (Cox-Maze ablation). Methods: The analysis is made based on clinical data and mathematical modeling. By the use of system of electro-anatomical mapping of radiofrequency ablation zones a three-dimensional model of left atrium is created. Then a potential map, which represents the amplitude of myocardium activity, is imposed

<strong>ABSTRACT</strong> In recent years, there is a rapid growth in the demand for electricity and this demand is geographically uneven.  Power is generated at remote locations and the wheeling of this power through AC lines is restricted by stability limitations. With the increasing size and complexity of transmission network its performance decreases. Hence there is a need for upgrading the existing system. This can be done by incorporating FACTS devices or by using HVDC transmission. FACTS devices are effective only for a limited distance and for long transmission HVDC is more advant

We have proposed previously a kinetochore motor-polar ejection model for chromosome congression to the metaphase plate where forces generated at the kinetochore are antagonized by away-from-the pole forces generated within each half-spindle on the chromosome arms. This model was based in large part on observations of the behavior of chromosomes on monopolar spindles. In these cells chromosomes typically become attached to the pole by only one kinetochore fiber. These mono-oriented chromosomes move to positions away from the pole even though they are pulled poleward at their kinetochores. Their

The detailed distribution of muscle activity within the biceps brachii (BB) muscle during isometric contraction as contraction intensity increases is not yet fully understood using multichannel surface electromyography (EMG). This study aimed to elucidate the distribution of muscle activity within the BB muscle during isometric contractions using monopolar and bipolar recording methods with multichannel surface EMG. The participants were 23 healthy young adults who performed a gradually increasing load task involving right elbow flexion for 10 seconds. The results showed that muscle activity w

Background: The ‘gold standard’ surgical treatment of clinically obstructive BPH is TURP, but life-threatening complications such as transurethral resection syndrome are occasionally observed. This has traditionally been provided as monopolar TURP, but morbidity associated with MTURP has led to the introduction of other surgical techniques. Objectives: To compare the effects of bipolar and monopolar TURP. Methods: In this prospective comparative study, 50 patients of each group undergo transurethral resection of prostate were enrolled and randomized to surgery by M‑TURP or B-TURP. Internationa

In the present work we present the THz emission spectra of bipolar n++–π–n+ structures (π is a high-resistance layer of p-type conductivity) of natural superlattices 4H-, 8H- and 15R-SiC at 7 K. The bipolar n++–π–n+ structures of 4H- and 8H-SiC were analogous to those of structures for which the negative differential conductivity effect was observed earlier for three polytypes (4H, 6H and 8H) at T=300

Introduction: There have been anecdotal reports of the efficacy of diathermy (electrocoagulation) in the prevention of neuroma formation. However, this has not been investigated in the laboratory. In this experiment involving 40 rats, diathermy was applied to the terminal proximal ends of transected rat common peroneal nerves to evaluate its effect on neuroma formation. Materials and Methods: Monopolar and bipolar diathermy set at 45 W, applied for different durations (4 seconds and 10 seconds), were evaluated. Under histological control, the presence of neuroma formation and the diameter of t

In bipolar Line commutated converter transmission lines are subjected to harsh weather condition so accurate and rapid clearance of fault is essential. A comparative study of the bipolar system with both converters healthy and one converter tripped is studied. Most of the research paper has focussed on transmission line faults in bipolar mode but none of them had focussed when HVDC system works in monopolar mode after the fault.

Proper evaluation and detection of uterine contraction is an important treat during gestation period. Uterine contraction happens by the generation of electrical activity from a given myometrial cell to the adjacent cell. There are various methods for monitoring uterine contraction but they lack to distinguish true labour contractions (efficient) from contractions that will not cause delivery (inefficient). One of the most accurate non-invasive technique for monitoring uterine contraction is the uterine electromyogram or Electrohysterogram (EHG). The main aim of this paper is to check whether
