Πληροφορική Β' Γυμνασίου - Το εσωτερικό του ΥπολογιστήGeorge Papamitsos
Ο υπολογιστής αποτελείται από διάφορα μέρη. Με μια πρώτη ματιά μπορούμε εύκολα να ξεχωρίσουμε τις περιφερειακές συσκευές ενός υπολογιστή. Στο εσωτερικό, όμως, της Κεντρική Μονάδας κρύβονται τα σημαντικότερα εξαρτήματα του.
Τι θα βλέπατε άραγε στο εσωτερικό του, αν ανοίγαμε το κουτί του υπολογιστη;
Από ποια βασικά μέρη αποτελείται εσωτερικά ο υπολογιστής;
Πόσο σημαντικό είναι να γνωρίζουμε τη χρησιμότητα των εσωτερικών μερών του υπολογιστή;

This document summarizes research on the electro-thermal and semiconductivity properties of a natural sintered complex carbonate ore. The ore was subjected to sintering treatments at temperatures ranging from 573 to 1273 K. Chemical, spectral, X-ray and thermal analyses were conducted on the native and sintered ore samples. The electrical conductivity, thermal conductivity, and thermoelectric power coefficient of the sintered ore materials were investigated as a function of temperature. Results showed that increasing the sintering temperature improved the electrical conductivity of the ore due to increased crystallinity and a more ordered crystal structure. Electron hopping between iron ions was found to be the main charge carrier mechanism.

Inhibition of Copper Corrosion by Arylazotriazoles in Nitric Acid Solution Al Baha University
. A study has been made to investigate the effect of some azoheterocyclic dyes of the type 3-arylazo 1,2,4-triazole (AT) on the corrosion of copper exposed to 0.5M nitric acid solution at different temperatures and at different AT concentrations. Using potentiodynamic polarization and Tafel electrochemical methods, it can be shown that AT compounds are good inhibitors of copper corrosion in HNO 3 solution. The kinetic and thermodynamic parameters of the inhibited system were determined. The high inhibition efficiency of these compounds may be due to the adsorption of the additive itself and/or the adsorption of the formed Cu(II)-AT complexes at the polarized electrode interface. Cathodic polarization measurements showed that AT dyes are predominantly cationic inhibitor
This document discusses project risk management. It provides details on the key steps in risk management: identification, analysis, planning, and review. It also explains the Generic Documentation Model (GDM), which provides a standardized structure for documenting processes across multiple levels including work packages, processes, and sub-processes. The GDM aims to establish common documentation and allows for quick reference and adaptation of documentation.

Inhibition, kinetic and thermodynamic effects of new Azo derivatives on iron ...Al Baha University
This investigation is designed to apply an advanced kinetic-thermodynamic model on the experimental data obtained from acidic and alkaline corrosion of iron using mono- and bis-azo dyes as corrosion inhibitors. The inhibition properties of the tested azo dyes on corrosion of iron in HNO3 and NaOH media were analyzed by gravimetric, thermometric and polarization measurements. The three studied methods gave consistent results. Polarization study showed that all the inhibitors are mixed type in acidic, act mainly as cathodic in alkaline solution. The synthesized azo dye derivatives exhibit good inhibition properties, obeys the Frumkin adsorption isotherm. The large values of the change in the standard free energy of adsorption (∆Goads), equilibrium constant (Kads) and binding constant (Kb) revealed that the reactions proceed spontaneously and result in highly efficient physisorption mechanism and stronger electrical interaction between the double layer existing at the phase boundary and the adsorbing molecules. The inhibition efficiency depends on the number of adsorption oxygen sites (OH and OMe groups), their charge density and π-electron clouds. The inhibition efficiency evaluated via theoretical methods was well accorded with reported experimental ones, following the same order as: -naphthyl- ligand > -naphthyl>p-anisdine>p-toluidine >o-toluidine >m-toluidine derivative. This research might provide a theoretical inhibition performance evaluation approach for homologous inhibitors.
This document outlines the development of a sign intended to encourage 4th and 5th grade orchestra students to practice their instruments regularly. It starts with messages about practicing consistently to improve playing skills. Various visual concepts are tried, including throwing tissues at a screen, bees, and a photoshopped image implying bike riding helps with practice. Feedback notes the need to steer away from clip art. The final sign features a girl embodying the courage needed to practice at home in pursuit of skill mastery.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Chengdu has a long history as a major urban settlement in Southwest China, with records of construction dating back over 2,300 years. As the capital of Sichuan province, it has grown significantly to house over 14 million inhabitants within its city limits. Chengdu is known for being the origin of Shu brocade silk production over 2,000 years ago, and is home to about 80% of the world's wild giant pandas, an animal that has become a global symbol of peace. The city's cuisine also gained international recognition when it was designated a UNESCO Creative City of Gastronomy in 2010.
The document provides information about visiting Beijing, China. It recommends visiting in the spring for mild weather, and suggests popular tourist destinations like the Great Wall, Summer Palace, Olympic Park, and tasting traditional food.

The document discusses and analyzes the logos of three major record labels - EMI, Sony, and Warner. For each logo, it identifies positives and negatives. The key points made are that EMI and Sony logos are very basic, focusing on clearly displaying the name. While simple, this makes the labels easy to recognize. Warner also keeps its logo basic but adds a small unique symbol. Overall, the document evaluates how the minimal yet recognizable designs of these record label logos effectively communicate their brands.
This document discusses opportunities for corporate involvement in organics recovery and biobased materials. It provides an overview of issues with petroleum-based plastics like their non-renewable source and negative environmental impacts. The benefits of composting organics and using biobased products are outlined. Various biobased materials from history are shown as alternatives to plastics. The document argues that biobased materials can replace some conventional plastics while being fully biodegradable and made from renewable resources. It notes that research and development in biobased alternatives is growing.
This document discusses the connections between wasting and climate change. Some of the key points made include:
1. 54% of waste is sent to landfills, which are a top source of methane emissions, a potent greenhouse gas.
2. Incinerators produce more carbon dioxide emissions per megawatt-hour than coal, oil, or natural gas power plants. They also require waste to operate.
3. Unchecked consumption and single-use items contribute greatly to waste. Composting and recycling programs are better alternatives that prevent emissions.

3. Είναι πολύ σημαντικό για την υγεία μας να
γνωρίζουμε τον τρόπο με τον οποίο
πρέπει να οργανώνουμε το περιβάλλον
εργασίας μας ώστε να μην
κουραζόμαστε και να είμαστε αποδοτικοί
όταν εργαζόμαστε.

4. Έτσι πρέπει να είμαστε σε θέση να
γνωρίζουμε την σωστή στάση που πρέπει
να έχουμε όταν καθόμαστε μπροστά
στον υπολογιστή για να μην προκαλούμε
προβλήματα στο σώμα μας π.χ να
βλάψουμε τη μέση, τα χέρια ή τα μάτια
μας. Με όλα αυτά ασχολείται η
Εργονομία!

6. H οθόνη χωρίζεται σε μικρές περιοχές (τετραγωνάκια) που
λέγονται εικονοστοιχεία (pixel). Κάθε pixel χρωματίζεται με ένα
μόνο χρώμα κάθε φορά. Όσο πιο πολλά εικονοστοιχεία έχουμε,
τόσο μεγαλύτερη είναι η ανάλυση της οθόνης!

7. Το μέγεθος της οθόνης μετριέται με το μήκος της διαγωνίου της οθόνης
σε ίντσες (1 ίντσα ισούται με 2,54 εκατοστά). Οι μεγαλύτερες οθόνες
κάνουν πιο ξεκούραστη την εργασία μας!
