    Energy consumption is influenced by various factors, including the proliferation of electronic devices, technological advancements, economic growth, agricultural development, and population increase. Each of these factors contributes to the rising demand for energy. This paper addresses the challenge of predicting peak energy demand (ED) by utilizing historical time series data from the past five years, combined with temperature data from Tamil Nadu’s official sources. We employed feature engineering techniques to prepare the data for machine learning models, specifically XGBoost regressor, lasso, and ridge regression. The time series data was then analyzed using both univariate and multivariate models, including auto regressive integrated moving average (ARIMA) and vector autoregressive (VAR) models. The results show that our models can effectively forecast ED, providing critical insights for policymakers and stakeholders involved in energy planning and resource management

    Background: Whole-genome sequencing represents a powerful experimental tool for pathogen research. We present methods for the analysis of small eukaryotic genomes, including a streamlined system (called Platypus) for finding single nucleotide and copy number variants as well as recombination events. Results: We have validated our pipeline using four sets of Plasmodium falciparum drug resistant data containing 26 clones from 3D7 and Dd2 background strains, identifying an average of 11 single nucleotide variants per clone. We also identify 8 copy number variants with contributions to resistance, and report for the first time that all analyzed amplification events are in tandem. Conclusions: The Platypus pipeline provides malaria researchers with a powerful tool to analyze short read sequencing data. It provides an accurate way to detect SNVs using known software packages, and a novel methodology for detection of CNVs, though it does not currently support detection of small indels. We have validated that the pipeline detects known SNVs in a variety of samples while filtering out spurious data. We bundle the methods into a freely available package

    Get PDF
    INTRODUCTION : Intestinal obstruction is defined as a failure in the downward passage of intestinal contents either due to a mechanical occlusion or from a fault in propulsive mechanism. Intestinal obstruction is one of the most common problems faced by the general surgeons. • The earliest recorded observation for intestinal obstruction was performed by Praxagoras (350 B.C.) who created an enterocutaneous fistula to relieve the obstruction. • However non-operative treatment has remained the general rule, including reduction of hernias, opium for pain, orally administered mercury or lead shot in an attempt to open up the occluded bowel, electrical stimulation and gastric lavage. • Intestinal obstruction both Mechanical and Adynamic is an enigma with its versatile presentation and wide spectrum of treatment options available. • Intestinal obstruction poses a dynamic challenge for the general surgeons to treat as the parameters change as the clock ticks on. TIME means everything and delay in the diagnosis or management increases the mortality. • With a wide range of conditions known to cause the Obstruction, the Surgeon should be well aware of the commonest causes in the geographical region of the presentation. • Keeping with these principles, the study hopes to discuss the etiological factors, clinical presentations and the most common causes. Our study focuses on using the basic diagnostic modalities for further diagnosis. This study presents an Overall view on Mechanical and adynamic Intestinal Obstruction in Adults OBJECTIVES: 1. To study the incidence of intestinal obstruction due to mechanical and adynamic causes. 2. To study the clinical presentation of intestinal obstruction. 3. To study the various etiological factors involved. MATERIALS AND METHODS: (a) Study design: Descriptive observational study (b) Study population: Cases admitted in the Department of Surgery, Stanley medical college, Chennai. (c) Inclusion criteria: Age 18 to 70 years, Diagnosis on admission. (d) Exclusion criteria: Morbidly ill patients, Patients not willing to participate in study. (e) Subject withdrawal: patients who went against medical advice without any treatment. (f) Period of study: one year (Dec 2013 – Dec 2014). (g) Study methods: Clinical examination, biochemical, radiological and other investigations, observations during surgery and their follow up are methods used in this study. The diagnosis is established by the admitting surgeon based on clinical picture and supported by radiological evidence (ultrasonogram, plain abdominal radiograph together with contrast studies if indicated) and confirmed during operation. Operative details shall include the cause of obstruction, presence or absence of strangulation and nature of operation performed. Post operative morbidity is defined in terms of the duration of hospital stay and associated complications following surgery. The observer will be present for 50 cases through out the initial evaluation, resuscitation and surgical procedure, information of the cases will be obtained from case records also. • Identification particulars viz., Name, Age, Sex, IP No. etc. • Clinical features and abdominal findings. • Radiological findings and contrast studies • Time of surgery after admission. • Operative findings. • Procedure done. • Postoperative complications. • Follow up. Patients will be followed up till the time of their discharge from hospital and two Months following surgery. Sample size: The study will be carried out in approximately fifty subjects who are selected from In patient in department of general Surgery. Statistical Methods: The data analyses will be made statistically using Chi square test to find the incidence ,clinical presentation and etiology of intestinal obstruction and using Microsoft excel software to arrive at the conclusion regarding the objective of the study. Colloborative Departments: The study will be done with the help of Department of Biochemistry ,pathology and microbiology for various biochemical parameters & Radiology. RESULTS: The incidence of acute intestinal obstruction in adult age group was studied from the cases admitted in Department of Surgery of Stanley medical college during the period December 2013 to December 2014. The data regarding the symptoms and signs and laboratory investigations has been adopted in 50 cases during the study period. During the period of 12 months,(studied 50 cases in 9 months) the total number of admissions in surgery were 14,236 cases. Of which 228 cases of acute intestinal obstruction were treated during these period which comprise 1.9% of total number of admissions among these surgically treated cases, 50 cases were randomly selected for the present study. Total number of emergency surgeries done in the department of Surgery were 1,569 and acute intestinal obstruction in this group consisted of about 14.53% of these surgeries. CONCLUSION: Acute intestinal obstruction remains an important surgical emergency in the surgical field. • Success in the treatment of acute intestinal obstruction depends largely upon early diagnosis,skilful management and treating the pathological effects of the obstruction just as much as the cause itself. • Erect abdomen X-ray is valuable investigation in the diagnosis of acute intestinal obstruction. • Obstructed hernias are the common cause to produce intestinal obstruction. Clinical radiological and operative findings put together can diagnose the intestinal obstruction. • Mortality is still significantly high in acute intestinal obstruction

    Introduction: While bariatric surgery leads to significant prevention and improvement of type 2 diabetes, patients may rarely develop diabetes after bariatric surgery. The aim of this study was to determine the incidence and the characteristic of new-onset diabetes after bariatric surgery over a 17-year period at our institution. Methods: Non-diabetic patients who underwent bariatric surgery at a single academic center (1997–2013) and had a postoperative glycated hemoglobin (HbA1c) ≥ 6.5%, fasting blood glucose (FBG) ≥ 126 mg/dl, or positive glucose tolerance test were identified and studied. Results: Out of 2263 non-diabetic patients at the time of bariatric surgery, 11 patients had new-onset diabetes in the median follow-up time of 9 years (interquartile range [IQR], 4–12). Bariatric procedures performed were Roux-en-Y gastric bypass (n = 7), adjustable gastric banding (n = 3), and sleeve gastrectomy (n = 1). The median interval between surgery and diagnosis of diabetes was 6 years (IQR, 2–9). At the last follow-up, the median HbA1c and FBG values were 6.3% (IQR, 6.1–6.5) and 95 mg/dl (IQR, 85–122), respectively. Possible etiologic factors leading to diabetes were weight regain to baseline (n = 6, 55%), steroid-induced after renal transplantation (n = 1), pancreatic insufficiency after pancreatitis (n = 1), and unknown (n = 3). Conclusion: De novo diabetes after bariatric surgery is rare with an incidence of 0.4% based on our cohort. Weight regain was common (> 50%) in patients who developed new-onset diabetes suggesting recurrent severe obesity as a potential etiologic factor. All patients had good glycemic control (HbA1c ≤ 7%) in the long-term postoperative follow-up

    The present study investigated the combined effects of zinc sulphate (ZnSO₄) and zinc solubilizing bacteria (ZSB) on black gram (Vigna mungo L.) growth and productivity in alkaline soils. Field experiments were conducted at two locations (Agricultural College and Research Institute, Madurai and Coastal Saline Research Centre, Ramanathapuram) during January 2022 using a randomized block design with eight treatments and three replications. The treatments included varying levels of ZnSO₄ (12.5, 18.75 and 25 kg ha-1) with and without ZSB (500 mL ha-1). Results showed that the combined application of ZnSO₄ (25 kg ha-1) and ZSB (500 mL ha-1) along with soil test-based NPK significantly enhanced plant growth parameters, including plant height (35.4 cm), shoot length (38.18 cm) and root nodules (27.4 per plant). This treatment also recorded the highest seed yield (851 kg ha-1), DTPA-extractable zinc (1.72 mg kg-1) and zinc uptake (84.73 g ha-1). The second most effective treatment was ZnSO₄ at 18.75 kg ha-1 with ZSB, which demonstrated comparable results and superior zinc use efficiency. The study concluded that integrating ZSB with optimal ZnSO₄ doses offers an effective strategy for improving black gram productivity and zinc nutrition in alkaline soils
