Supported by real-world case studies, this essential textbook provides a detailed overview of the use of biostatistical tools and methods, enabling students and researchers to undertake their own research with confidence and understanding.After a general introduction to the field, the book provides a step-by-step description of the essential statistical methods that are foundational to analyzing data from clinical trials, epidemiological studies, and other health-related research. From basic concepts such as probability and distribution through to hypothesis testing, regression analysis, survival analysis, meta analysis and systematic reviews, each chapter is designed with a clear pedagogical approach featuring explanatory diagrams, real-life examples and sample problems. Later sections of the book cover clinical trial design and analysis, diagnostic testing, Bayesian methods and machine learning. Through this detailed, comprehensive treatment of the key tools and methods, the book encourages readers to develop their own critical thinking skills, recognising good or bad pieces of research when they see them, asking questions about where evidence and assumptions come from, or choosing the most appropriate biostatistical methodologies in their own research.Written by a team of experts with extensive teaching experience in this field, this is the ideal textbook for graduate students and researchers across the biomedical sciences, from Public Health to Epidemiology to Clinical Medicine.

Water is crucial for rice cultivation, with total water needs depending on evapotranspiration (ETc), seepage, and percolation. These factors vary based on soil type, crop growth stage, and climatic conditions across agro-ecological environments. This study estimates crop water and irrigation requirements in Raipur District, Chhattisgarh, using the MABIA method in WEAP software. The method, based on the dual crop coefficient, simulates daily evapotranspiration. FAO guidelines and the irrigator's formula determine irrigation needs, while ArcGIS generates block-wise irrigation maps. Results show rice crop water requirements range from 648.66 mm to 847.87 mm in the Kharif season, with irrigation needs between 1,23,193 MCM and 2,57,533 MCM, depending on agricultural area. Accurate estimation prevents crop wilting or excessive water loss. The WEAP model results, validated against observed data, show only a 2.5% deviation, confirming reliability. This study aids in optimizing water use for improved rice production.

This book investigates the pollution of the Sheonath River in India, analyzing the impact of industrial and domestic waste over two years. The study examines the river's declining water quality through physico-chemical and biological assessments, revealing high levels of pollutants such as heavy metals, organic waste, and nutrients. These contaminants have disrupted the river's self-purification process, affecting aquatic ecosystems and making the water unsuitable for human consumption. The research identifies indicator organisms to evaluate water health and correlates pollution levels with industrial discharges. To mitigate contamination, the authors propose sustainable remediation methods, including bioreactors, aerated lagoons, and the Integrated Aquatic Macrophyte-Based System (IAMBS), which uses aquatic plants for natural filtration. The book underscores the urgency of effective waste management and ecological restoration to safeguard the Sheonath River and other freshwater resources from further degradation.

Groundwater is one of nature's most valuable resources, yet increasing demand and inadequate recharge have led to its steady depletion. This study focuses on the Kharun Basin, a sub-basin of the Mahanadi River, covering parts of Raipur, Dhamtari, and Durg districts in Chhattisgarh. Using Visual MODFLOW software, groundwater availability and flow were modeled for 2010-2011, incorporating key parameters such as hydraulic conductivity, recharge, and storage. Results reveal severe groundwater scarcity in the middle and northern regions, highlighting the need for rainwater harvesting and storage expansion in critical areas like Gunderdehi, Kurud, and Tilda. Sensitivity analysis indicates an inverse relationship between hydraulic conductivity and water head in unconfined aquifers. This study offers crucial insights for effective groundwater management, providing a framework for sustainable resource planning and conservation.

Demystifies non-contact warfare, and explores the labyrinth of development post-World War II. Disruption, denial, distortion, disempowerment, destabilisation and destruction are a few themes that the world is likely to witness as the dominance strategy using non-contact warfare unfolds.

Ideal as a graduate textbook, this title is aimed at helping design effective biomaterials, taking into account the complex interactions that occur at the interface when a synthetic material is inserted into a living system.
