Numeri e Crittografia
Number Theory is one of the most classic fields of Mathematics. The numbers he deals with are those that are called natural 0, 1, 2, ... and that we use since childhood to count. Seemingly simple and harmless, they nevertheless hide some of the most difficult and exciting mysteries of the whole of mathematics. Cryptography, on the other hand, is concerned with hiding the content of confidential communications from prying eyes and corresponds to widespread needs in our society. The Theory of Numbers can help Cryptography in these needs, thanks to the mysteries that still surround it. The text gives an account of this link. It first introduces Modern Cryptography, its goals and priorities. He then goes on to expose arguments of Number Theory, with particular reference to the two problems of recognizing prime numbers, and of decomposing a natural into its prime factors; for each of the two issues it provides a vast panorama of the algorithms that deal with it and try to solve it as effectively as possible. In particular, it presents the very recent AKS procedure for recognizing prime numbers. The book then returns to Cryptography and shows how ideas and methods of Number Theory apply to the construction of reliable procedures for the secure transmission of confidential information.

Intelligent glasses store
Technology has been found to facilitate humankind's life. Hence, there is a new technique almost every day. One of the most common is E-commerce. This is the first project in Syria. about online glasses Shop, which displays sets of glasses on a website. The website allows the shopkeeper (the admin) to add their collections of glasses. Set prices and show reservations. Users can view glasses on the website and try whatever he wants by real-time or by recording video, then they add the preferred ones to the cart to reserve the sample they like the most for a specific time. This project aims to allow busy traders to make their own business online, in addition, it saves time and effort for them and users as they can make shopping and compare goods whatever the situation is especially in quarantine.
Indiscrete Thoughts
Indiscrete Thoughts gives a glimpse into a world that has seldom been described, that of science and technology as seen through the eyes of a mathematician. The era covered by this book, 1950 to 1990, was surely one of the golden ages of science as well as of the American university. Cherished myths are debunked along the way as Gian-Carlo Rota takes pleasure in portraying, warts and all, some of the great scientific personalities of the period —Stanislav Ulam (who, together with Edward Teller, signed the patent application for the hydrogen bomb), Solomon Lefschetz (Chairman in the 1950s of the Princeton mathematics department), William Feller (one of the founders of modern probability theory), Jack Schwartz (one of the founders of computer science), and many others.
Il solito Albert e la piccola Dolly : La scienza dei bambini e dei ragazzi = The usual Albert and little Dolly : The science of children and young people
After hundreds of years, science has come out of the ivory tower and entered society. Today science is not done with laboratory research alone but by involving different social actors. There are scientists, but also politicians, administrators, entrepreneurs and ordinary people, young and old. Their fears, real or perceived, can put a stop to its development. Their trust and their hopes nourish it and create a climate of expectations that are not always met. In the great narrative of science, the first actors, the scientists, are from time to time destroyers and benefactors, saints or monsters, fathers of the Golem with feet of clay or of Frankestein who turns and destroys. Not infrequently then there are many Sisyphus who continually restart their business - and it is not excluded that in the eyes of some they share with Penelope the habit of undoing at night what they do during the day.

Human vision and the night sky : How to improve your observing skills
This book is not for beginners. Nor is it for experts – instead it addresses the needs of practical amateur astronomers who want to make the jump to the new challenges of serious visual observing. Second Steps in Observational Astronomy begins by teaching you, as an amateur astronomer, to use the most important tool you have: your eyes. Visual observing is very definitely a skill that can be learned. Of course it is important to have your other optical equipment – telescope and accessories – set up and operating as perfectly as possible. This book describes how. After these vital preliminaries, subsequent chapters include a series of observing challenges that will entertain you and push your observing skills to continually higher levels of excellence for years to come. Take a tour of the solar-system as you never viewed it before, then beyond into the realm of deep space – using just your own eyes to reveal more detail than you ever thought possible.

Gesture smart control
Nowadays actions are increasingly being handled in electronic ways, instead of physical interaction. From earlier times biometrics is used in the authentication of a person. It recognizes a person by using a human trait associated with it like eyes (by calculating the distance between the eyes) and using hand gestures, fingerprint detection, face detection etc. Advantages of using these traits for identification are that they uniquely identify a person and cannot be forgotten or lost. These are unique features of a human being which are being used widely to make the human life simpler. Hand gesture recognition system is a powerful tool that supports efficient interaction between the user and the computer.
Frontiers in Chemical Sensors : Novel Principles and Techniques
With their similarity to the organs of the most advanced creatures that inhabit the Earth, sensors are regarded as being the “senses of electronics”: arti?cial eyes and ears that are capable of seeing and hearing beyond the range of - man perception; electronic noses and tongues that can recognise odours and ?avours without a lifetime training; touch that is able not only to feel the texture and temperature of the materials but even to discern their chemical compo- tion. Among the world of chemical sensors, optical devices (sometimes termed “optodes”, from the Greek “the optical way”) have reached a prominent place in those areas where the features of light and of the light-matter interaction show their advantage: contactless or long-distance interrogation, detection sensitivity, analyte selectivity, absence of electrical interference or risks, and lack of analyte consumption,

La phytocosmétologie thérapeutique = Herapeutic phytocosmetology
Deals with restorative cosmetology. This is understood through the eyes of the doctor specializing in phytotherapy. Three main aspects are discussed: the diagnosis of disturbance of the skin and integuments, external treatment with natural substances, as well as oral treatment (internal treatment). Oral cosmetology has no official recognition, yet the effects of plant extracts on the condition of the skin and integuments are well known. After an introduction to the physiology of the skin, the dosage and the phenomena of skin deterioration, the author discusses different types of treatment depending on the extracts used while explaining their mode of action. This work was written by a doctor, Doctor Paul Goetz, teacher in clinical phytotherapy, and a pharmacist, Doctor Christian Busser, pharmaceutical and scientific advisor, doctor in ethnology and ethnopharmacologist.
Binocular astronomy
Anyone who has used a binocular telescope or even wide-field binoculars to look at the night sky will know just how breathtakingly beautiful the view can be when you observe with both eyes. Observing galaxies and nebulae with ‘regular’ prismatic binoculars is just a beginning. Binocular eyepieces and adapters can be added to almost any commercially-made astronomical telescope, and of course specialized astronomical binoculars can be assembled or purchased complete. These range from modest instruments to giants that are basically two large telescopes mounted together. Binocular Astronomy contains everything you’ll need to know about this exciting branch of astronomical observing.
Artificial tears drops
Vision is by far the most used of the five senses and is one of the primary means that we use to gather information from our surroundings. More than 75% of the information we receive about the world around us consists of visual information. The tear film is structurally complex with three distinct layers: a surface lipid layer, a middle aqueous layer and an inner mucus layer. Dry eyes are caused by a variety of reasons that disrupt the healthy tear film...
Antidiabetic medicinal plants and herbal treatments
Diabetes is a chronic condition associated with metabolic disorder. Persons suffering from diabetes have shown accelerated levels of blood sugar which often harms the heart, blood vessels, eyes, kidneys, and nerves. Over the past few decades, the prevalence of diabetes has been progressively increasing. Synthetic drugs are used to treat diabetic patients to help control the disorder, but it is shown that numerous medicinal plants and herbal drugs are widely used in several traditional systems of medicine to prevent and treat diabetes. They are reported to produce beneficial effects in combating diabetes and alleviating diabetes-related complications. These plants contain phtyonutrients and phytoconstituents demonstrating protective or disease preventive properties. In many developing countries, herbal drugs are recommended by traditional practitioners for diabetes treatment because the use of synthetic drugs is not affordable.
