Effetto dello zolfo sul rendimento del grano

Effetto dello zolfo sul rendimento del grano

Avinash Kumar Rai; Sumit Rai; Pankaj Kumar

Edizioni Sapienza
2025
pokkari
L'India, in termini di produzione e di superficie, occupa oggi il secondo posto tra i Paesi produttori di grano del mondo. La produzione mondiale totale di grano stimata in 605,9 milioni di tonnellate da 216,6 milioni di ettari nel 2005-2006, con un contributo dell'11,4%. Lo zolfo essenziale per la sintesi di proteine, vitamine e aminoacidi essenziali contenenti zolfo ed anche associato al metabolismo dell'azoto. Lo zolfo migliora la resa e la qualit delle colture. La carenza di zolfo nel suolo aumenta con l'intensificazione dell'agricoltura. Le variet reattive dei fertilizzanti hanno accelerato l'esaurimento degli aumenti di zolfo nel suolo, anche a partire da profondit inferiori. L'uso continuo di fertilizzanti privi di zolfo ha portato a un'ampia diffusione della carenza di zolfo nei terreni indiani, che diventa pi vantaggiosa nei terreni a tessitura leggera e a basso contenuto di materia organica. Le informazioni sull'effetto dello zolfo sulla resa, sulla qualit e sull'assorbimento dei nutrienti nelle colture di grano sono limitate. Tenendo conto di questi fatti, la presente indagine stata condotta per studiare l'effetto dei livelli di zolfo sulle propriet fisico-chimiche del suolo e sul rendimento del grano (Triticum aestivum L.).

An Operative Manual of Proximal Femoral Fractures

An Operative Manual of Proximal Femoral Fractures

Dhananjay Gupta; Sumit Banerjee

Jaypee Brothers Medical Publishers
2016
nidottu
The proximal femur is the top part of the thigh, closest to the hip joint. Injury can cause discomfort and mobility problems, making accurate treatment vital. This book is a guide to the diagnosis and management of proximal femoral fractures for orthopaedic trainees. Divided into five sections, each part discusses fractures in a different part of the femur, providing an overview of the fracture, followed by surgical treatment options. Difficult and rare fractures are covered, and the final section examines fractures in children, periprosthetic fractures, and pathological fractures. More than 200 images enhance learning. Key points Guide to the diagnosis and surgical management of proximal femoral fracturesDifferent types of fracture discussed in detail, including difficult and rare fracturesFinal section dedicated to ‘special scenarios’ including proximal femoral fractures in childrenIncludes more than 200 images

Biology: Fundamental Principles (Edition1st)

Biology: Fundamental Principles (Edition1st)

Balaji S Thorat; Sumit M Raut

Astral International Pvt Ltd
2023
sidottu
The book Biology: Fundamental Principles is designed to serve as a text book for B.Sc. (Agricultural & Traditional University) students and would be of help to those in M.Sc. This book covers origin of life and its evidences, classification and taxonomy of plant & animals. In this book also includes basic biology principles viz., cell & its division and germination of crops. As far as possible, the examples are drawn from Indian experience. The book is written in simple language and even complex concepts have been reduced to early understandable discussions. The authors are attempted incorporate the recent developmental information in field of biology without sacrificing the simplicity of language or style. Discussions on nomenclature, introduction to Genetics and plant systematics-study of families are unique features of this book.

Dilemma of Development Among the Onge of Andaman

Dilemma of Development Among the Onge of Andaman

Dipali Danda; Sumit Mukherjee

The Onge of Little Andaman, one of the surviving important Negrito communities in the world, have a very small static population since last four decades. There have been several critical issues pertaining to adopting the induced changes in their habitat and economy. The volume presents detailed documentation and indepth analysis of the situation and concerns related to their survival. The volume is the outcome of a prolonged field investigation and research presented in the form of analytical and development ethnography with eco-logical, socio-cultural, economic and political perspectives of a dwindling community listed under Particularly Vulnerable Tribal Group of India. The Onge have ever been rather vulnerable toward any option for radical change, they deserve close, careful attention to ward off any untoward impact of change-initiatives.The authors, a team composed of an Anthropologist and a Human Ecologist, have tried to throw light on the degree of agreements between the induced change programmes and the peoples' age-old survival strategy. The depth of the authors' intimate interaction with the people, their ecology, cultural niche, psychology, economy, and in a way the livelihood as such, presents a flavour hitherto unknown. The volume is remarkably enriched with good number of rare photographs along with important maps, charts and illustrations. This work is an invaluable record for reviewing and revising process and outcome of the long continued welfare programme before further such appli-cation on the remaining groups in the archipelago. The local and global level researchers, teachers and planners, interested in foraging tribal population and issues related to their welfare, development, etc., will certainly find this volume extremely useful.

Applied Artificial Neural Network Methods For Engineers And Scientists: Solving Algebraic Equations

Applied Artificial Neural Network Methods For Engineers And Scientists: Solving Algebraic Equations

Snehashish Chakraverty; Sumit Kumar Jeswal

World Scientific Publishing Co Pte Ltd
2021
sidottu
The aim of this book is to handle different application problems of science and engineering using expert Artificial Neural Network (ANN). As such, the book starts with basics of ANN along with different mathematical preliminaries with respect to algebraic equations. Then it addresses ANN based methods for solving different algebraic equations viz. polynomial equations, diophantine equations, transcendental equations, system of linear and nonlinear equations, eigenvalue problems etc. which are the basic equations to handle the application problems mentioned in the content of the book. Although there exist various methods to handle these problems, but sometimes those may be problem dependent and may fail to give a converge solution with particular discretization. Accordingly, ANN based methods have been addressed here to solve these problems. Detail ANN architecture with step by step procedure and algorithm have been included. Different example problems are solved with respect to various application and mathematical problems. Convergence plots and/or convergence tables of the solutions are depicted to show the efficacy of these methods. It is worth mentioning that various application problems viz. Bakery problem, Power electronics applications, Pole placement, Electrical Network Analysis, Structural engineering problem etc. have been solved using the ANN based methods.

Compressed Sensing Magnetic Resonance Image Reconstruction Algorithms

Compressed Sensing Magnetic Resonance Image Reconstruction Algorithms

Bhabesh Deka; Sumit Datta

Springer Verlag, Singapore
2019
sidottu
This book presents a comprehensive review of the recent developments in fast L1-norm regularization-based compressed sensing (CS) magnetic resonance image reconstruction algorithms. Compressed sensing magnetic resonance imaging (CS-MRI) is able to reduce the scan time of MRI considerably as it is possible to reconstruct MR images from only a few measurements in the k-space; far below the requirements of the Nyquist sampling rate. L1-norm-based regularization problems can be solved efficiently using the state-of-the-art convex optimization techniques, which in general outperform the greedy techniques in terms of quality of reconstructions. Recently, fast convex optimization based reconstruction algorithms have been developed which are also able to achieve the benchmarks for the use of CS-MRI in clinical practice. This book enables graduate students, researchers, and medical practitioners working in the field of medical image processing, particularly in MRI to understand the need forthe CS in MRI, and thereby how it could revolutionize the soft tissue imaging to benefit healthcare technology without making major changes in the existing scanner hardware. It would be particularly useful for researchers who have just entered into the exciting field of CS-MRI and would like to quickly go through the developments to date without diving into the detailed mathematical analysis. Finally, it also discusses recent trends and future research directions for implementation of CS-MRI in clinical practice, particularly in Bio- and Neuro-informatics applications.
