Basic Immunology and Its Clinical Application (Advances in Experimental Medicine and Biology #1444)
by Mitsuru MatsumotoThis book overviews ongoing and upcoming clinical applications of basic immunology. Recent advances in our knowledge of immunology coupled with new technologies have aided in the development of efficient cancer immunotherapy, as well as the control of emerging microorganisms such as SARS-CoV-2. However, knowledge of basic immunology has not been fully utilized even after the discoveries of immune checkpoint inhibition for cancer immunotherapy and the development of mRNA vaccination against SARS-CoV-2. There is still room for improving the clinical application of basic immunology. The book summarizes the achievements in clinical applications of basic immunology and highlights what can be further extended to make immunology a more practical human science. Basic immunology and its clinical applications are two wheels of the same cart in the immunology field, which aids in the development of more efficient cancer immunotherapy and rapid control of infectious diseases against microorganisms, including new viruses and classical toxoplasmosis. The exploration of ongoing and upcoming applications of basic immunology in this book makes it a useful resource for immunologists, physicians, molecular and genome biologists, bioinformaticians, and students in these fields.

Basic Critical Theory for Photographers
by Ashley la GrangeBasic Critical Theory for Photographers generates discussion, thought and practical assignments around key debates in photography. Ashley la Grange avoids the trap of an elitist and purely academic approach to critical theory, taking a dual theoretical and practical approach when considering the issues. Key critical theory texts (such as Sontag's 'On Photography' and Barthes' 'Camera Lucida') are clarified and shortened. La Grange avoids editorilising, letting the arguments develop as the writers had intended; it is the assignments which call into question each writer's approach and promote debate.This is the ideal book if you want to understand key debates in photography and have a ready-made structure within which to discuss and explore these fascinating issues. It is accessible to students, from high school to university level, but will also be of interest to the general reader and to those photographers whose training and work is concerned with the practical aspects of photography.Also includes invaluable glossary of terms and a substantial index that incorporates the classic texts, helping you to navigate your way through these un-indexed works. The book also contains useful information on photo-mechanical processes, explaining how a photograph can appear very differently, and as a result be interpreted in a range of ways, in a variety of books.

Basi di Hacking: Guida all'Hacking Etico e ai Test di Penetrazione per Principianti
by Adidas WilsonIn origine, il termine “hacker” indicava un programmatore esperto di sistemi operativi per computer e di codice macchina. Oggi si riferisce a chiunque svolga attività di hacking. Per “hacking” si intende la capacità di modificare le caratteristiche di un sistema per raggiungere un obiettivo che non rientra nelle intenzioni originali di chi ha creato il sistema. Alla parola “hacking” è di solito associato un significato negativo, soprattutto da persone che non comprendono il lavoro di un hacker etico. Nel mondo dell’hacking, gli hacker etici sono brave persone. Qual è il loro ruolo? Essi usano la loro vasta conoscenza dei computer per intenti buoni, e non cattivi. Più specificamente, essi cercano le vulnerabilità nella sicurezza dei computer di organizzazioni e aziende per impedire ai malintenzionati di trarne vantaggio. Per chi ama il mondo della tecnologia e dei computer, sarebbe saggio considerare una carriera di hacker etico. Si viene pagati (con una buona somma) per entrare nei sistemi. All'inizio non sarà una passeggiata nel parco, proprio come per qualsiasi altra carriera. Tuttavia, se sei determinato, puoi arrivare in alto e avere una carriera redditizia. Se decidi di iniziare questo viaggio, dovrai avere pazienza. Di solito, il primo passo per molte persone è ottenere una laurea in informatica. Puoi anche ottenere una certificazione A + (CompTIA), per la quale devi però sostenere e superare due diversi esami. Per poter sostenere il test di qualificazione, è necessario avere non meno di 500 ore di esperienza in informatica pratica. Per far avanzare la tua carriera, sono richieste esperienza e una qualifica CCNA o Network +. Questo libro sarà la tua porta d’ingresso nel mondo dell’hacking etico.
