Gli scienziati avrebbero sviluppato in laboratorio 7 tipi di cui poi è stata analizzata la struttura tramite una macchina di luce di sincrotrone britannica, presso il Diamond Light Source. Successivamente, gli scienziati hanno immerso i cristalli in soluzioni ed hanno osservato per la prima volta come fanno questi prodotti&amp;nbsp; ad agganciare la proteina-bersaglio e a neutralizzarla. Ma a quanto pare questa volta i ricercatori hanno colpito nel segno: ora si potranno finalmente ottenere dei farmaci efficaci contro l’Aids.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: black;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&lt;span style=&quot;color: #ff0000;&quot;&gt;&lt;span style=&quot;font-size: medium;&quot;&gt;Alunno :Luca Mariotti III°B&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

In questo modo si renderebbe molto più agevole la creazione di idrogeno. L’impiego su larga scala potrebbe essere un valido metodo per la produzione efficiente di energia e combustibile a idrogeno. I ricercatori hanno modificato un virus innocuo per l’uomo,che modificato a dovere e grazie all’impiego dell’ossido di iridio,riesce ad aggregarsi con la porfirina di zinco, creando così un composto chimico capace di spezzare le molecole d’acqua.&amp;nbsp;L’agente virale, mantenuto stabile grazie all’inglobamento in una matrice di micro gel, risulta essere molto efficiente nella scissione delle molecola di acqua..&amp;nbsp; Il virus risulta essere un efficace sistema capace di produrre 4 atomi di ossigeno, mentre è ancora in fase di sviluppo l’altra metà del processo, la produzione di idrogeno.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p class=&quot;MsoNormal&quot; style=&quot;margin: 0cm 0cm 0pt;&quot;&gt;&lt;span class=&quot;apple-style-span&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p class=&quot;MsoNormal&quot; style=&quot;margin: 0cm 0cm 0pt;&quot;&gt;&lt;span class=&quot;apple-style-span&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;Alunno: Luca Mariotti III°B&lt;/span&gt; &lt;a target=&quot;_blank&quot; href=&quot;http://web.mit.edu/mitei/research/spotlights/split-water.html&quot;&gt;&lt;/a&gt;&lt;br style=&quot;mso-special-character: line-break;&quot; /&gt; &lt;br style=&quot;mso-special-character: line-break;&quot; /&gt;&lt;/span&gt;&lt;/p&gt;

Le capanne,si estendono per circa 40m in maggioranza circolari, ma anche rettangolari. Le capanne sono&lt;span style=&quot;mso-spacerun: yes;&quot;&gt;&amp;nbsp;&amp;nbsp;&lt;/span&gt; circa 50, sono divise in due quartieri e sono addossate alle pareti della dolina.&lt;/span&gt;&lt;/span&gt; &lt;span class=&quot;nero101&quot;&gt;&lt;span style=&quot;color: black; font-family: Arial; mso-bidi-font-family: 'Times New Roman';&quot;&gt;Le strutture presentavano pianta rettangolare, quadrangolare, circolare o ellittica. I muri, di modesto spessore, erano realizzati mediante l’utilizzo di pietre in calcare locale appena sbozzato e di malta; la malta era ottenuta miscelando suolo argilloso (terre rosse) e ghiaia, con l’aggiunta anche di inerti organici,&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;color: black; font-family: Arial; mso-bidi-font-family: 'Times New Roman';&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;esse sono in parte crollate soprattutto a causa di scavi clandestini all'inizio del Novecento. &lt;span style=&quot;mso-spacerun: yes;&quot;&gt;&amp;nbsp;&lt;/span&gt;Le origini del villaggio sono ancore misteriose, infatti la tecnica costruttiva differisce da quella degli altri villaggi nuragici, comunque si pensa che&lt;span style=&quot;mso-spacerun: yes;&quot;&gt;&amp;nbsp;&lt;/span&gt; il sito fu frequentato a lungo. Il villaggio tiscali è realizzato con una tecnica costruttiva diversa dagli altri villaggi nuragici.&lt;/span&gt;&lt;/span&gt; &lt;span class=&quot;nero101&quot;&gt;&lt;span style=&quot;color: black; font-family: Arial; mso-bidi-font-family: 'Times New Roman';&quot;&gt;La tessitura muraria era regolarizzata riempiendo di malta gli interstizi,tra una pietra e l’altra la malta era poi esternamente levigata, seguendo l’aggetto delle pareti. Negli spessori murari interni erano spesso ricavati degli stipetti e delle nicchie per custodire gli arredi.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style=&quot;margin: 0cm 0cm 0pt; text-align: justify;&quot; class=&quot;MsoNormal&quot;&gt;&lt;/p&gt; &lt;p style=&quot;margin: 0cm 0cm 0pt; text-align: justify;&quot; class=&quot;MsoNormal&quot;&gt;&lt;span style=&quot;color: black; font-family: Arial; mso-bidi-font-family: 'Times New Roman';&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;Alunno: Cristian Gelsomino I°A&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style=&quot;margin: 0cm 0cm 0pt; text-align: justify;&quot; class=&quot;MsoNormal&quot;&gt;&lt;span style=&quot;color: black; font-family: Arial; mso-bidi-font-family: 'Times New Roman';&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style=&quot;margin: 0cm 0cm 0pt; text-align: justify;&quot; class=&quot;MsoNormal&quot;&gt;&lt;span style=&quot;color: black; font-family: Arial; mso-bidi-font-family: 'Times New Roman';&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style=&quot;margin: 0cm 0cm 0pt; text-align: justify;&quot; class=&quot;MsoNormal&quot;&gt;&lt;span style=&quot;color: black; font-family: Arial; mso-bidi-font-family: 'Times New Roman';&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

Sappiamo anche che se stiamo vicini a chi non viene punto riusciamo &lt;a target=&quot;_blank&quot; href=&quot;http://blogsmscalangianus.myblog.it/media/00/02/292282597.jpg&quot;&gt;&lt;img name=&quot;media-1208325&quot; src=&quot;http://blogsmscalangianus.myblog.it/media/00/02/702304981.jpg&quot; alt=&quot;zanzara.jpg&quot; style=&quot;border-width: 0; float: left; margin: 0.2em 1.4em 0.7em 0;&quot; id=&quot;media-1208325&quot; /&gt;&lt;/a&gt;di sfruttare, anche se non totalmente, la sua &lt;span style=&quot;mso-spacerun: yes;&quot;&gt;&amp;nbsp;&lt;/span&gt;immunità. Anche nel mondo animale esistono casi simili, in un gregge di mucche per esempio, noterete pochissime zanzare. Queste e tante altre osservazioni hanno spinto i ricercatori a pensare che ci sono sostanze per così dire mascheranti rilasciate dagli esseri viventi, che sono in grado di confondere le zanzare. Dopo uno studio sulle reazioni della zanzare della febbre gialla agli odori di alcuni volontari sono stati selezionati una serie di composti che portano il grado di attrattivi di una persona a un livello simile a quello dell’aria. “Noi produ&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-size: small;&quot;&gt;ciamo odori che attraggono le zanzare, ma alcuni ne producono altri che li mascherano” ha spiegato il professore James Logan uno dei membri del team di ricerca. Secondo i ricercatori, quindi, sarà possibile produrre repellenti anti-zanzare inodore, al contrario di tutti quelli attualmente in commercio. I composti isolati sono 11, non resta che valutare il loro grado di efficacia.&lt;/span&gt;&lt;/strong&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style=&quot;margin: 0cm 0cm 0pt;&quot; class=&quot;MsoNormal&quot;&gt;&lt;span style=&quot;font-size: 14pt; color: black; font-family: Verdana;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&lt;strong&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/strong&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style=&quot;margin: 0cm 0cm 0pt;&quot; class=&quot;MsoNormal&quot;&gt;&lt;span style=&quot;font-size: 14pt; color: black; font-family: Verdana;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&lt;strong&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;span style=&quot;font-size: medium; color: #00ff00; font-family: Arial Black;&quot;&gt;Zaccagni Daiana IIA&lt;/span&gt;&lt;/strong&gt;&lt;/span&gt;&lt;/span&gt;&amp;nbsp;&lt;/p&gt;

Nell’arco di un giorno si elimina quasi un litro di sudore (800 ml). In estate sotto il sole, la sudorazione raddoppia, così come durante uno sforzo fisico o una tensione emotiva, un appuntamento importante, una prova di coraggio o di paura. Si può sudare in modo molto abbondante e la pelle può irritarsi. Sudare può provocare dei problemi al cervello, perché lo invecchi di un anno. &lt;span class=&quot;notiziatesto&quot;&gt;&lt;span style=&quot;mso-bidi-font-weight: bold;&quot;&gt;In estate&amp;nbsp; la sudorazione aumenta&lt;/span&gt; per il caldo, così come aumenta con lo sforzo fisico o per la tensione emotiva. &lt;span style=&quot;mso-bidi-font-weight: bold;&quot;&gt;Il sudore è una miscela a base acquosa&lt;/span&gt; incolore o tendente al biancastro, a volte quasi lattescente.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt; &lt;span style=&quot;font-size: 14pt; color: windowtext;&quot;&gt;&lt;span style=&quot;font-family: Times New Roman;&quot;&gt;Il sudore serve essenzialmente alla &lt;span style=&quot;mso-bidi-font-weight: bold;&quot;&gt;termoregolazione&lt;/span&gt; del nostro corpo, infatti, nel momento in cui la temperatura interna tende a salire, l’organismo cerca di espellere acqua calda (calore) per riportare il nostro termometro naturale ai livelli normali.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style=&quot;background: white; line-height: 18pt; text-align: justify;&quot;&gt;&lt;span style=&quot;font-size: 14pt; color: windowtext;&quot;&gt;&lt;span style=&quot;font-family: Times New Roman;&quot;&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;span style=&quot;color: #ff0000;&quot;&gt;Alunno&lt;/span&gt;: &lt;span style=&quot;color: #00ff00;&quot;&gt;Conti&lt;/span&gt; &lt;span style=&quot;color: #ffff00;&quot;&gt;Sergio&lt;/span&gt; &lt;span style=&quot;color: #ff00ff;&quot;&gt;II&lt;/span&gt;°&lt;/span&gt;&lt;span style=&quot;color: #3366ff;&quot;&gt;B&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
