    El TNP (2,4,6-trinitrofenol) es el nombre IUPAC del ácido pícrico, altamente soluble en agua y más explosivo por naturaleza que el TNT. Se utilizó en la Primera Guerra Mundial y en guerras anteriores como la ruso-japonesa, la batalla de Omdurman, la Segunda Guerra Bóer, etc. Su uso generalizado como antiséptico para el tratamiento del herpes, la viruela, el tratamiento de quemaduras, la malaria, en las industrias de tintes y en los laboratorios químicos supone una importante amenaza para la seguridad del medio ambiente. La ingesta de TNP provoca varios problemas en los seres humanos, como irritación ocular y cutánea, mal funcionamiento del hígado, problemas relacionados con los sistemas urinario, gastrointestinal y respiratorio, así como enfermedades crónicas como anemia, cianosis y cáncer. El 2-amino-4,6-dinitrofenol, un metabolito del TNP, es 10 veces más mutagénico que éste. Por lo tanto, es necesario desarrollar sensores de TNP para el medio ambiente y la seguridad de diferentes portales de entrada como: aeropuertos, estaciones de tren/autobús, lugares turísticos, centros comerciales y otros lugares públicos.

    TNP (2,4,6-Trinitrofenol) é o nome IUPAC do ácido pícrico, altamente solúvel em água e mais explosivo do que o TNT. Foi utilizado na Primeira Guerra Mundial e em guerras anteriores, como a guerra russo-japonesa, a batalha de Omdurman, a Segunda Guerra dos Bóeres, etc. A sua utilização generalizada como anti-sético para o tratamento de herpes, varíola, queimaduras, malária, em indústrias de corantes e em laboratórios químicos impõe uma ameaça significativa à segurança do ambiente. A ingestão de TNP causa vários problemas nos seres humanos, como irritação dos olhos e da pele, mau funcionamento do fígado, problemas relacionados com os sistemas urinário, gastrointestinal e respiratório, bem como doenças crónicas como a anemia, a cianose e o cancro. O 2-Amino-4,6-dinitrofenol, um metabolito do TNP, é 10 vezes mais mutagénico do que o TNP. Por isso, é necessário desenvolver sensores de TNP para o ambiente e a segurança de diferentes portais de entrada, tais como: aeroportos, estações de comboios/autocarros, pontos turísticos, centros comerciais e outros locais públicos.

    Il TNP (2,4,6-Trinitrofenolo) è il nome IUPAC dell'acido picrico, altamente solubile in acqua e di natura più esplosiva del TNT. È stato utilizzato nella prima guerra mondiale e in altre precedenti, come la guerra russo-giapponese, la battaglia di Omdurman, la seconda guerra boera, ecc. Il suo uso diffuso come antisettico per il trattamento dell'herpes, del vaiolo, delle ustioni, della malaria, nelle industrie dei coloranti e nei laboratori chimici costituisce una minaccia significativa per la sicurezza dell'ambiente. L'assunzione di TNP causa diversi problemi nell'uomo, come irritazione degli occhi e della pelle, malfunzionamento del fegato, problemi legati all'apparato urinario, gastrointestinale e respiratorio, nonché malattie croniche come anemia, cianosi e cancro. Il 2-amino-4,6-dinitrofenolo, un metabolita del TNP, è di per sé 10 volte più mutageno del TNP. È quindi necessario sviluppare sensori di TNP per l'ambiente e la sicurezza di diversi ingressi, come aeroporti, stazioni ferroviarie e degli autobus, luoghi turistici, centri commerciali e altri luoghi pubblici.

    TNP (2,4,6-Trinitrophenol) ist die IUPAC-Bezeichnung für Pikrinsäure, die sehr gut wasserlöslich und von Natur aus explosiver ist als TNT. Es wurde im Ersten Weltkrieg und davor eingesetzt, z. B. im Russisch-Japanischen Krieg, in der Schlacht von Omdurman, im Zweiten Burenkrieg usw. Seine weit verbreitete Verwendung als Antiseptikum zur Behandlung von Herpes, Pocken, Verbrennungen, Malaria, in der Farbstoffindustrie und in chemischen Labors stellt eine erhebliche Gefahr für die Sicherheit der Umwelt dar. Die Aufnahme von TNP verursacht beim Menschen verschiedene Probleme wie Augen- und Hautreizungen, Leberfunktionsstörungen, Probleme im Zusammenhang mit dem Harn-, Magen-Darm- und Atmungssystem sowie chronische Krankheiten wie Anämie, Zyanose und Krebs. 2-Amino-4,6-dinitrophenol, ein Metabolit von TNP, ist selbst 10-mal mutagener als TNP. Daher ist es notwendig, TNP-Sensoren für die Umwelt und die Sicherheit an verschiedenen Eingangsportalen wie Flughäfen, Bahnhöfen/Busbahnhöfen, Touristenorten, Einkaufszentren und anderen öffentlichen Orten zu entwickeln.

    This edited book is a comprehensive collection of scientific research on different plants under drought and salt stress conditions. The main focus of this book is to elaborate on the mechanisms being operative in plants under stress and how various biological factors mitigate the adverse effects for better plant productivity. This book covers all physiological, biochemical, and molecular mechanisms operating under drought and saline stresses. The current status and impact of drought and salinity on various crop plants have been elaborated on in different chapters. Agricultural lands are either turning barren or becoming more saline and drought-prone with increasing temperatures, decreasing water tables, untimely rainfall, and other environmental factors. In India, salt-affected soils occupy an area of about 6.73 million ha of which saline and sodic soils constitute roughly 40 and 60%, respectively. All these factors individually or cumulatively, affect the plant growth and development and hence, the crop productivity with the monetary loss. The inbuilt plant's ability with modified/acclimatized mechanisms has been described in various chapters with step-wise descriptions. The role of various plant growth-promoting agents including nano-particles, micro-organisms, metabolites or phytohormones, etc in mitigating adverse effects of drought and salinity has been explained precisely. Updated information on the use of speed breeding, proteomics, epigenetics, and transcriptomics in different crops along with high throughput technologies is included for the cross-talk of various network mechanisms. This book is helpful for the readers in knowing salinity and drought through the physiological, biochemical and genetic, and molecular levels to understand plant behaviour under stress conditions. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, plant physiology, biochemistry, forestry, and environmental sciences. National and international agricultural scientists and policymakers will also find this to be a useful read.

    Adi Shankaracharya, the great philosopher who re-established the Vedic sanatana dharma, was born in Kalady, a village in the present Ernakulam district of Kerala state in India in 507 BC on the Vaisakha Shukla Panchami day of the Hindu calendar. His father was Shivaguru and mother Aryamba. At the age of 8 years, he received the initiation into sanyasa order from the venerated GovindaBhagavatpada on the Kartika Shukla Ekadashi. He wrote commentaries on the Prasthanatrayishastras. Shankaracharya appeared at a time when the circumstances were such that the sanatana dharma was rendered devoid of any strength, was torn apart and destroyed. There were also foreign invasions. By his scholarly aptitude and strength of his penance, he defeated Buddhist scholars in philosophical debates. He also defeated scholars like Sri Mandana Mishra by his command of shastras and made him his disciple. He had profound accomplishments by age 16. He also influenced King Sudhanva and made him his disciple. Adi Shankaracharya traveled far and wide across several regions, preached and professed extensively the vedicsanatana dharma in an all too brief lifespan of 32 years. He woke up the society that was in a state of deep slumber. He wrote many books and had many temples renovated in his lifetime. In order to have the dharma rule over the country always and have spiritual values progress, the great seer established four dharmic institutions.

    Biotechnology is the science and technology of building functional structures and devices. In Greek, ¿Biotechnology¿ derives from the bio which means life and technologia means systematic treatment of an art or craft. Nanostructured inorganic, organic, and biological materials may have existed in nature since the evolution of life started on Earth. Some evident examples are micro-organisms, fine-grained minerals in rocks, and nano size particles in bacteria and smoke. From a biological viewpoint, the DNA double-helix has a diameter of about 2 nm (20 angstrom) while ribosomes have a diameter of 25 nm. Atoms have a size of 1¿4 angstrom; therefore nanostructured materials could hold tens of thousands of atoms all together. Moving to a micrometer scale, the diameter of a human hair is 50¿100 _m. Advancements in microscopy technology have made it possible to visualize images of nanostructures and have largely dictated the development of nanotechnology.

    This book provides insight into the use of molecular and genomic techniques to the study of populations of critically important species at various geographical scales. It delves into a wide range of issues relevant to biodiversity conservation, such as population differentiation, landscape genomics, ecological interactions, phylogenetics, phylogeography, metagenomics, molecular methods, and data processing. The current rate of biodiversity loss is unprecedented and valuable genetic resources are being lost at an alarmingly rate. Effective strategies to conserve these genetic resources are essential to maintain healthy ecosystems with inter-dependent species. The book is an invaluable resource for training undergraduate and graduate students, postdoctoral fellows, and for young researchers. This book is particularly useful for the policy makers and academics who want to learn about important concepts in population and conservation genetics and genomics.

    Although boron (B) is a micronutrient, it is frequently found at toxic concentrations in soils and ground waters in arid and semi-arid conditions worldwide. Boron poses a challenge as its management is difficult due to its high permeability and presence as an uncharged molecule at physiological pH. B is now recognized as a toxic component of the saline milieu which interacts with salinity and further aggravates its toxic effects. Interactions between salinity and B toxicity are rather complex. The mechanism of boron uptake under saline conditions is not well known. Under saline and excessive B conditions, absorption and translocation of B by passive diffusion might be inhibited by decreased transpiration rates. Inadequate information regarding the response of plants to the combination of excess B and salinity on plant growth and yield is available. So, this study was undertaken to analyze and compare the combined effect of boron and salinity and to evaluate the response of wheat varieties differing in their tolerance to boron and salinity stresses.
