The Global Survey of the Electrical Energy Distribution System: A Review
This paper gives a review of energy scenario in India and other countries. Today’s demand of the world is to minimize greenhouse gas emissions, during the production of electricity. Henceforth over the world, the production of electrical power is changing by introducing abundantly available renewable energy sources like sun and wind. But, because of the intermittent nature of sustainable power sources, the electrical power network faces many problems, during the transmission and distribution of electricity. For resolving these issues, Electrical Energy Storage (EES) is acknowledged as supporting technology. This paper discusses about the world electrical energy scenario with top renowned developed countries in power generation and consumption. Contribution of traditional power sources changed after the introduction of renewable energy sources like sun and wind. Worldwide Agencies are formed like International Energy Agency (IEA), The Central Intelligence Agency, (CIS) etc. The main aim of these agencies is to provide reliable, affordable and clean energy. This paper will discuss about the regulatory authority and government policies/incentives taken by different countries. At the end of this paper, author focuses on obstacles in implementation, development and benefits of renewable energy
FIRST JURASSIC EVIDENCE OF A POSSIBLE SPINOSAURID PEDAL UNGUAL, FROM THE JAISALMER BASIN, INDIA
We describe an isolated, almost complete pedal ungual phalanx from the Middle Jurassic marine carbonate rocks of the Jaisalmer Basin, Rajasthan, north-western India. The ungual bone is triangular shaped, pointed, elongated, asymmetrical, dorsoventrally compressed, ventrally flat, bearing a shallow semi-circular excavation, and almost straight in lateral view. The morphological features, as well as its proportions closely resemble the pedal ungual phalanges of spinosaurid theropods, presently known dominantly from the Cretaceous. The affinity to spinosaurids is supported by bivariate and multivariate analyses. The ungual phalanx is tentatively identified as a basally branching Jurassic spinosaurid under Megalosauroidea. Considering the stratigraphical and geographical provenances, this contribution may represent the oldest record of a spinosaurid
Machine Learning Approach for Catastrophe Risk Assessment and Management Using Remote Sensing Data
With emergency programs for disaster preparedness and warning phases for earthquakes, landslides, and floods in recent years, remote sensing and geographic information systems have played a crucial role in Catastrophe Risk assessment and management. It has also been a key focus in the field of technology. Without the right tool for organizing massive volumes of data and gathering information from many sources, such maps or measurement channels, it would not be feasible to employ sensory data. In order to identify and assess areas affected by floods, earthquakes, avalanches, landslides, and wildfires, this study employs machine learning approaches. Following the application of filters to enhance image quality, the images are segmented through thresholding technique and classified using supervised and unsupervised classification methods. Images from before and after disasters are gathered from MRSAC Nagpur and processed using Python-based tools, ArcGIS, ERDAS, and QGIS for the purpose of analyzing devastation
EV-SIFT - An Extended Scale Invariant Face Recognition for Plastic Surgery Face Recognition
Automatic recognition of people faces many challenging problems which has experienced much attention due to many applications in different fields during recent years. Face recognition is one of those challenging problem which does not have much technique to solve all situations like pose, expression, and illumination changes, and/or ageing. Facial expression due to plastic surgery is one of the additional challenges which arise recently. This paper presents a new technique for accurate face recognition after the plastic surgery. This technique uses Entropy based SIFT (EV-SIFT) features for the recognition purpose. The corresponding feature extracts the key points and volume of the scale-space structure for which the information rate is determined. This provides least effect on uncertain variations in the face since the entropy is the higher order statistical feature. The corresponding EV-SIFT features are applied to the Support vector machine for classification. The normal SIFT feature extracts the key points based on the contrast of the image and the V- SIFT feature extracts the key points based on the volume of the structure. But the EV- SIFT method provides the contrast and volume information. This technique provides better performance when compare with PCA, normal SIFT and V-SIFT based feature extraction
Advocating Platelet Rich Plasma Therapy (PRP) as Assuring Treatment Modality in Acute Fissure in Ano-A Case Report
PRP or autologous platelet-rich plasma, has been hailed as a successful method of treating wounds. There is, however, still a shortage of data to back up its application in patients with both acute and chronic wounds. This study set out to thoroughly investigate the efficacy, synergy, and potential mechanism of PRP-mediated treatment for acute fissure-in-ano. Acute fissure with indications of pain, bleeding, and elevated sphincter tone was identified at six o'clock. As a control, PRP was applied to the area of the fissure. The pace of fissure healing, as well as the reduction in discomfort, bleeding, and sphincter tone, were evaluated on the third and tenth days. PRP significantly enhanced fissure healing, which was connected to wound healing control, angiogenesis augmentation, re-epithelialization, and collagen deposition. As PRP raises local vascular intensity, enhances re-epithelialization, and is linked to increased growth factor production, it dramatically improves the healing process of fissures while also reducing discomfort, bleeding, and worsened sphincter tone
An open-label, prospective study comparing efficacy, tolerability and cost of therapy of losartan with enalapril in stage 1 and stage 2 hypertension
Background: Hypertension is a chronic disease which insidiously affects multiple systems in the body especially the cardiovascular and cerebrovascular systems. Also being a chronic disease the patient is required to take medications lifelong and this has financial implications. This study was attempted to evaluate drugs in two antihypertensive groups: Angiotensin II antagonist losartan v/s angiotensin converting enzyme inhibitor enalapril. Methods: A total of 100 patients as per the selection criteria were enrolled in the study and allocated randomly to either group A (losartan group) or group B (enalapril group). The study period was for 12 weeks, during which regular assessments were done - first on recruitment and then at 2nd week, 4th week, 8th week, and 12th week. The assessment parameters were diastolic, systolic pressures and pulse rate. Routine investigations were performed during the 1st visit and after 12 weeks of the study period.Results: There were no significant differences between the treatment groups with respect to baseline patient demographic data and clinical characteristics like systolic blood pressure, diastolic blood pressure and heart rate. The cost benefit ratio and less adverse effects (cough), can be appreciated in group A (losartan group).Conclusions: Losartan and enalapril were well tolerated after 12 weeks of treatment with notable tolerability advantages of losartan especially with respect to the respiratory system (cough). The cost of therapy for losartan group was almost half the cost of therapy for enalapril group and hence being cost effective. Thus, losartan could be preferred as a suitable alternative to enalapril as an antihypertensive agent
Prevalence of Bronchogenic carcinoma in the North Indian Population
Aim: This original research article aims to study the Prevalence of Bronchogenic carcinoma in the North Indian Population.
Material & Method: The present study includes 150 patients with intrathoracic space-occupying lesions, of which 42 patients with bronchogenic carcinoma were seen at SS hospital Banaras Hindu University, Varanasi, UP. Most of the patients studied were from the thoracic surgery section, while few patients were taken from other departments of SS hospital. The age of those patients varied widely, starting from 10 years to 60 years. The bulk of the patients were young adults and middle-aged persons, with 35 males and seven females. During this study, patients were investigated in systemic order with the progression of symptoms from the onset, development of latest symptoms and treatment taken before if any, history of tuberculosis, chronic cough, smoking, and contact with were recorded. The patient's vitals were recorded, and routine pathological investigation including blood count, hemoglobin and specific procedure like radiological method, sputum and bronchoscopy were performed.
Result: Maximum patients were in the age group of 41 to 50 years. Forty-two patients were diagnosed with Bronchogenic carcinoma, a definitive diagnosis was confirmed by Clinical & Radiological (chest X-ray & CT Scan) in 24 (16%), by Bronchoscopic examination & Biopsy in 15 (10%) and by thoracotomy in 03(2%). The maximum age group among the cases were 41-60. The most common symptom was Cough with expectoration in 33 patients (78.5%), followed by Haemoptysis and Dyspnea in 30 cases (71.4%). Fever was least common with 6 cases. It was observed that 18 patients (43%) had the habit of smoking for more than 18 years.
Conclusion: This study provides a framework for assessing the prevalence of bronchogenic carcinoma in the North Indian population and proves that smoking is a potential risk factor in bronchogenic carcinoma. Prevalence of Bronchogenic Carcinoma among all cases of Intrathoracic Lesions Cases 28 % and among all subjects who undergone for screening in one year – 2.84
