Available in PDF, EPUB and Kindle. Book excerpt: Storia più o meno simile al vero di molecole giunte dallo spazio e dei loro tentativi di formare macromolecole importanti per la vita, microrganismi, cellule and Co., nonché di loro fallimenti come i virus, raccontata con terminologia comprensibile a tutti, almeno nelle intenzioni dell’autore. Il testo è tratto da tre conferenze sull’origine della vita sul nostro pianeta, la sua lenta evoluzione, unica nell’universo, fino alla comparsa degli organismi superiori, piante e animali. Il lettore viene gradualmente accompagnato in un percorso pieno di interrogativi durato 4 miliardi e mezzo di anni circa. Il discorso parte dal tentativo di scoprire il mistero della transizione non vivente‑vivente, o del momento in cui si sia formata la prima cellula elementare, e, attraverso le vicende dei procarioti, continua fino alla comparsa delle cellule eucariote che hanno permesso la nascita degli organismi pluricellulari, compreso noi Sapiens. La vita è nata nell’acqua e nell’acqua si è evoluta per quattro lunghissimi miliardi di anni con pochissime testimonianze, poi le sue conquiste si sono potute documentare attraverso i fossili che si sono conservati per milioni anni in diversi substrati, fino alla difficile lotta di piante e animali per conquistare le terre emerse 600‑500 milioni di anni fa.

Download or read book Prebiotic chemistry and the origin of life written by Giovanni Occhipinti and published by Youcanprint. This book was released on 2024-01-15 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Born from twenty-five years of experimental research and a decade of bibliographic studies, this publication delves into the fascinating theory of life's abiotic origins. It begins with simple amino acids, the building blocks of proteins, revealing how these compounds, present from the prebiotic era and discovered in ancient meteorites, may have been pivotal in life's evolutionary journey. Focusing particularly on amino acids' chirality—that is, their existence in mirror-image right and left forms—the author probes the critical enigma of their separation and why the left (L) form dominates in all known living beings. The book sparks a compelling discussion about how this bifurcation might have occurred at life's very inception and the ultimate fate of the right form. The text further extends its reach, proposing theories on the genetic code's origins, the selection of the 20 natural amino acids from many known, and a physical theory of consciousness in bacteria. "Prebiotic Chemistry and the Origin of Life" is more than a trek through the complexities of chemistry and molecular biology; it's an enthralling journey into some of life's most profound existential questions.

Download or read book Immunized Plants written by Ruggero Osler and published by Celid. This book was released on 2023-03-16 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cultivated plants, despite scientific progress, are paradoxically becoming more fragile and more at risk of disease than in the past: testifying to the endless waves of epidemics that are hitting our countryside and vineyards. Owing to commonly used agronomic techniques we are undermining biodiversity and the natural resilience of our crops. To confront costly and dangerous diseases, like epidemics, bold and innovative protection strategies are needed. Instead of combatting the pathogen and the vector head on, this book focuses on the plant host and the real possibility of reinforcing that host through a process of induced resistance. All plants, grapevines included, like animals, learn from their “experiences” and are able to become immunized: after infection, they can become resistant to diseases and other stress factors. This volume proposes the use of plants that are naturally immunized, those that have passed the gauntlet of Darwinian natural selection and have demonstrated stable and transmissible tolerances and resistances.

Available in PDF, EPUB and Kindle. Book excerpt: Per secoli l'umanità è stata afflitta da una visione antropocentrica di se stessa che l'ha condotta a considerarsi signora e padrona assoluta del mondo e della natura. In virtù di questa opinione tutto il creato, la terra, i fiumi, i monti, lo sterminato universo della flora e della fauna, nonché quello dei paesaggi e degli ambienti, quella che con termine scientifico all'interno di questo studio viene definita biodiversità, sono stati considerati al servizio esclusivo dell'uomo, del suo benessere e del suo progresso, quasi fossero dei servitori nati con l'unico scopo di obbedire ai desideri umani.

Download or read book New Approaches to Teaching Italian Language and Culture written by Emanuele Occhipinti and published by Cambridge Scholars Publishing. This book was released on 2008-12-11 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Approaches to Teaching Italian Language and Culture fills a major gap in existing scholarship and textbooks devoted to the teaching of Italian language and culture. A much-needed project in Italianistica, this collection of essays offers case studies that provide a coherent and organized overview of contemporary Italian pedagogy, incorporating the expertise of scholars in the field of language methodology and language acquisition from Italy and four major countries where the study of Italian has a long tradition: Australia, Canada, Great Britain and the United States. The twenty four essays, divided into six main parts, offer a tremendous variety of up-to-date approaches to the teaching of Italian as a foreign language and L2, ranging from theoretical to more practical, hands-on strategies with essays on curricular innovations, technology, study abroad programs, culture, film and song use as effective pedagogical tools. Each case study introduces a systematic approach with an overview of theory, activities and assessment suggestions, collection of research data and syllabi. The book addresses the needs of instructors and teacher trainers, putting in perspective different examples that can be used for more effective teaching techniques according to the ACTFL guidelines and the Common European Framework of Reference for Languages.

Download or read book The Custodians of Biodiversity written by Pablo Balbontín Arenas and published by Fao Inter-Departmental Working Group. This book was released on 2003 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural biodiversity is a precious legacy which we have a moral duty to pass on intact to future generations. As farming systems modernise, these crucial resources risk being lost, unless effective conservation measures are put in place and sufficient recognition is given to the role of the farmer in food security and agricultural development. This publication contains a number of black and white photographs by Pablo Balbontân Arenas, which give an insight into the life and customs of small farmers who foster, maintain and use genetic diversity in traditional agricultural systems, deploying local techniques and knowledge accumulated over many centuries, focusing on four crops: wheat, rice, maize and potato. The accompanying text is written in English, Spanish and Italian.

Book excerpt: Come ha avuto origine la vita per evoluzione o per creazione? Che questa sia la domanda numero 1 più importante del mondo non vi è nessun dubbio. ___ L'unica risposta esatta, comunque, varia anche tra i più prominenti scienziati ed esperti letterati dell'intero pianeta. ___ Ovviamente una persona dalla mentalità scientifica risponderebbe che l'origine della vita è avvenuta per "evoluzione" cioè che una specie animale o/e vegetale si sia trasformata in modo del tutto autonomo in varie specie. ___ Diversamente, una persona, anche se non è necessariamente religiosa, sceglierebbe di confermare che l'origine della vita è avvenuta per "creazione", cioè che un Onnipotente Iddio ha creato ogni specie animale e/o vegetale indistintamente in base al proprio disegno e volontà. ___ Qual è quindi la vera risposta a questa interessante domanda così rilevante? Diciamo che molte persone istruite, tra cui non pochi scienziati, mettono in dubbio la validità della teoria dell'evoluzione, e questo per diversi motivi assai vigorosi: "è solo un'idea, un'opinione senza alcun reale fondamento". ___ Questo libro vi risponde in modo assai esaustivo, ma non con ipotesi come troppo spesso fa la scienza, ma con fatti e analisi, con le prove e con un ragionamento razionale e altamente conoscitivo delle materie molecolari sia animate e sia inerte.

This book was released on 2013-11-20 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'idea di trattare un argomento così vasto, come la biodiversità, mi è venuta in mente proprio pensando al piccolo paese dove vivo. Conoscere meglio ciò che ci è vicino è più facile sotto molti aspetti, pensare sempre al globale può fuorviare le menti e illuderle che qualcosa di concreto possa avvenire. Spesso riteniamo che le nostre azioni quotidiane non possano ricadere sull'ambiente e sulle ideologie che guidano la nostra società. Invece è dalle singole azioni di ognuno che si è costruita questa società che ora inizia a vacillare. Si ha la sicurezza che i Paesi sviluppati ormai godano di benessere e che non possano essere toccati dall'insufficienza alimentare e invece non è così. Se l'uomo continua senza sosta a sfruttare le risorse incidendo sugli equilibri naturali, l'umanità non avrà probabilmente scampo.
