Analisi delle precipitazioni tra due AWS poste a quote diverseStefano Lanzi
L’obiettivo di questo lavoro è stato quello di individuare le eventuali relazioni tra le nevicate registrate da due stazioni meteorologiche automatiche posizionate lungo la valle dei Forni durante l’inverno 2014-2015. La posizione delle due stazioni è particolare, in quanto consente di considerare simultaneamente le condizioni meteorologiche lungo la valle dei Forni, seguendo un gradiente altitudinale che va dai 1730 metri della AWS SC ai 2631 metri della AWS1 Forni.

This document outlines a lesson plan for introducing functions to high school students using a flipped classroom approach. The lesson begins with an introductory activity to activate prior knowledge. Students then watch explanatory videos and explore websites on functions as homework. In class, students work in groups to discuss the material, solve practice problems, and create a mind map. The teacher checks understanding through individual exercises and addresses any questions. The goal is for students to understand the definitions of functions, domains, and ranges.

As we all know chromatographic fingerprinting of botanicals is a quite recent concept. This presentation will help to the beginners to understand basic thories and fundamantals of thin layer chomatography. The presentation will also provide basic experiemental understanding to perfrom HPTLC fingerprinting of samples/extracts/formulations.
This document outlines a study to screen and analyze selected plant species for their antioxidant properties. The objectives are to:
1. Screen 3-4 plant species from forest regions for antioxidant properties.
2. Identify primary and secondary metabolites in plant extracts.
3. Isolate and quantify bioactive antioxidant compounds and determine medicinal value.
4. Compare antioxidant profiles between plant species.
Plants will be extracted using solvent extraction. Phytochemical analysis will test for compounds like alkaloids, flavonoids, tannins. Total phenolic content and flavonoid content will be determined colorimetrically. Antioxidant capacity will be evaluated using DPPH, ABTS, hydroxy
This document describes the process of protoplast isolation, culture, and fusion from Ankita Singh and Vinars Dawane of the Government Holkar Science College in Indore. It provides an overview of protoplast isolation methods including mechanical, sequential enzymatic, and mixed enzymatic. Sources of protoplasts include leaves, callus cultures, and cell suspension cultures. The viability of isolated protoplasts can be tested through microscopy, tetrazolium reduction, fluorescein diacetate staining, and Evan's blue staining. Protoplasts are cultured through regeneration of cell walls, cell division, and development of callus/whole plants. Protoplast fusion can be spontaneous, mechanical, or

3. SCOPO DELL’ESPERIMENTO
Determinare il rapporto carica/massa (q/m), dell'elettrone per mezzo di un tubo a
fascio elettronico filiforme detto tubo di Wehnelt.
DESCRIZIONE DELL’ESPERIMENTO
Si alimentano le due bobine di Helmholtz fino ad ottenere una traiettoria
circolare disposta su un unico piano. Si prende nota del valore dell'intensità di
corrente e si misura il raggio della circonferenza percorsa dagli elettroni.
Facendo variare l'intensità di corrente nelle bobine e la tensione anodica si
misurano i raggi delle nuove traiettorie circolari percorse dagli elettroni.
CONCLUSIONE
Dato che la Forza di Lorentz è una forza centripeta possiamo conoscere la
velocità dell’elettrone a partire dalla differenza di Potenziale.
½ mv^2=eV
Dunque, il rapporto carica massa si può scrivere:
e/m=2V/(Br)^2

6. SCOPO DELL’ESPERIMENTO
Determinare la distanza focale di una lente convergente, montata su un banco
ottico e usufruendo di un proiettore di luce attraverso il metodo di Bessel.
DESCRIZIONE DELL’ESPERIMENTO
CONCLUSIONE
-Si pone l’oggetto vicino il proiettore e la lente a distanza arbitraria
-Si sposta lo schermo finchè non si osserva una nitida immagine
-Si misurano le distanze oggetto-lente (p) e immagine-lente(q) tenendo conto
dell’incertezza
- Si misurano le dimensioni dell’oggetto e della rispettiva immagine
Attraverso l’applicazione della formula : f=(pq)/(p+q) si trova la distanza focale
della lente e si confronta con il valore sperimentale.
Si procede analogamente per trovare l’ingrandimento della lente tenendo presente
la formula: m=q/p
