Enlightened readers, it has always been my endeavour to create awareness about the various evils happening in the society through my writings. In this effort, in my book, I have tried to present various unfair practices and actions taking place in the society through two great persons of Satyayug. Which, create awareness among the knowledgeable readers and also bring awareness about these acts in the society and also try to ensure that no living being has to face suffering due to our conduct. I not only hope but am confident that you will definitely like this effort of mine.

Teacher is that person in our life, who teaches us many other important things along with good education. A teacher means a lot to his students. It plays a very important role in our life from the initial stage of development till we mature. Education is very important in the life of all of us. Only an ideal teacher can show this education the right path. The ideal teacher is assessed by his character and academic ability. A student's life is incomplete without a teacher. My effort is also to show the various works done by such a great teacher for the society. Their sacrifice and duty cannot be ignored. It is also the duty of our society that keeping that selfless service in mind, special status should be given in the society.

This book discusses all major topics on survey sampling and estimation. It covers traditional as well as advanced sampling methods related to the spatial populations. The book presents real-world applications of major sampling methods and illustrates them with the R software. As a large sample size is not cost-efficient, this book introduces a new method by using the domain knowledge of the negative correlation between the variable of interest and the auxiliary variable in order to control the size of a sample. In addition, the book focuses on adaptive cluster sampling, rank-set sampling and their applications in real life. Advance methods discussed in the book have tremendous applications in ecology, environmental science, health science, forestry, bio-sciences, and humanities. This book is targeted as a text for undergraduate and graduate students of statistics, as well as researchers in various disciplines.

Peppers are one of popular vegetables because of the combination of colour, taste and nutritional value. Peppers contain a wide array of phytochemicals and are a good source of vitamin C and carotenoids that are important nutritional antioxidants found in the human diet. Vitamin C is hypothesized to prevent cancer by inhibiting the formation of N-nitroso compounds in the stomach, and by stimulation the immune system. Vitamin C is also the most abundant water-soluble antioxidant in the human body. Carotenoids are fat-soluble antioxidants found in many fruits and vegetables and are required for human epithelial cellular differentiation. In addition, peppers were reported to contain moderate to high levels of neutral phenolics or flavonoids, phytochemicals that are important antioxidant components of a plant-based diet, other than traditional nutrients, that may reduce the risk of degenerative diseases. Flavonoids are widely distributed in the plants. Flavonoids are reported to possess many biochemical and pharmacological effects, including antioxidation, antiinflammation and antiallergy. Flavonoid intake was reported to reduce cancer risk. Flavonoids inhibited enzymes such as prostaglandin synthase, lipoxygenase and cyclooxygenase, closely related to tumorigenesis.

The book offers a perfect source to document state-of-the-art developments and innovations in nanocomposite membranes, ranging from materials development and characterization of properties to membrane applications. The book discusses applications that encompass the enhancement of sorption and degradation processes and their usage for the removal of different pollutants, including heavy metals, dyes, pesticides, and other organic and inorganic pollutants from the industry.

Lanthanides Series Determination by Various Analytical Methods describes the different spectroscopic and electrochemical methods used for the determination and measurement of lanthanides. Numerous examples of determination methods used in real sample analysis are gathered and explained, and the importance of lanthanides as applied in chemical industry, agriculture, clinical and pharmaceutical industry, and biology is discussed, with many applications and recent advantages given.

Migraine has evolved into a giant puzzle and its literature comprises a vast loosely-linked enterprise challenging human problem-solving capacity. There is no central idea in migraine to elaborate a general theory which in turn could ultimately lead to creation of a unifying hypothesis that collects the various strands of evidences into a coherent and logically defensible intelligible synthesis. Current pathogenetic concepts of migraine, in particular cortical spreading depression (CSD), do not focus on the precise onset of the attack. Neither the aura nor the headache represents the true beginning of a migraine attack. The primary or causal physiological alteration underlying migraine lies in the 'pre-prodromal' phase, the variable interim between exposure to the headache-provoking stimulus or situation and the onset of the migraine prodrome. The migraine prodrome itself can last several hours to a few days. Since CSD is believed to underlie both the migrainous scintillating scotoma as well as the headache, it cannot be regarded as an early or initial 'pre-prodromal' physiological event. The biology of migraine is not the study of laboratory 'markers' but the elucidation of physiological forces (trait and/or state factors) that push (precipitate) or pull (predispose) patients towards aura/headache or aura/headache-free state. The pathophysiology of migraine has been hitherto confined to analyses of diverse precipitating and remitting factors and uncertain postulations about recorded laboratory aberrations into presumptive causal algorithms. The key cranial physiological system involved in migraine remains unidentified. Migraine attacks occur during stress and, more commonly, after cessation of stress. The author has earlier proposed that a physiological neuroendocrine 'system' comprised of well-regulated parallel activation of the vasopressinergic, intrinsic brain serotonergic, and intrinsic brain noradrenergic systems constitutes an important adaptive mechanism that governs vascular integrity, antinociception, behaviour and overall function during stressful occasions, including migraine attacks. Such a conceptual template can be used to segregate the vast phenomenology of migraine into primary pathogenetic or secondary non-pathogenetic divisions; non-pathogenetic migrainous phenomena can be further subdivided into adaptive and concomitant (epiphenomenal) physiological events. Nausea and/or vomiting, facial pallor, Raynaud's phenomenon, episodic daytime sleepiness, and relative hypotension (both spontaneous as well as induced by prophylactic anti-migraine pharmacologic agents) likely reflect the non-pathogenetic (adaptive or epiphenomenal) clinical components of migraine. The pathophysiological basis of aura/headache and nausea/vomiting of migraine is very unlikely to be identical. Exogenous magnesium does not readily cross the intact blood-brain barrier and decreases the permeability of the blood-brain barrier. Magnesium depletion appears to serve an important adaptive function; its utility in migraine management is not convincing. Magnesium depletion, platelet activation, peripheral alterations in serotonin and catecholamine metabolism, hyper-responsiveness of brain noradrenergic, serotonergic, vasopressinergic, and dopaminergic systems, parasympathetic nevous system activation, pupillary miosis, and cutaneous allodynia probably represent some of the secondary adaptive physiological mechanisms operative in migraine. A critical or central role for brain neuronal involvement in migraine pathogenesis appears unikely as established migraine preventive agents like atenolol, nadolol, and verapamil do not readily cross the intact blood-brain barrier or influence brain neuronal function. Antidepressants, including amitriptyline, induce brain noradrenergic and serotonergic hyperfunction, rendering highly unlikely that such brain states underlie migraine. Elucidation of adaptive physiological mechanisms in migraine can rationalise important epidemiological, clinical, and pharmacological features and sow the seeds for evolution of an integrative synthesis which process, in turn, might herald the creation of a comprehensive thought framework and research vision for migraine.
