  • THE ISLAMIC CIVILIZATION Qadar Bakhsh Baloch
    Qadar Bakhsh Baloch The Dialogue THE ISLAMIC CIVILIZATION Qadar Bakhsh Baloch “Thus we have appointed you a mid-most nation, that you may be witnesses upon mankind.” (Quran, 11:43) ISLAM WAS DESTINED to be a world religion and a civilisation, stretched from one end of the globe to the other. The early Muslim caliphates (empires), first the Arabs, then the Persians and later the Turks set about to create classical Islamic civilisation. In the 13th century, both Africa and India became great centres of Islamic civilisation. Soon after, Muslim kingdoms were established in the Malay-Indonesian world, while Muslims flourished equally in China. Islamic civilisation is committed to two basic principles: oneness of God and oneness of humanity. Islam does not allow any racial, linguistic or ethnic discrimination; it stands for universal humanism. Besides Islam have some peculiar features that distinguish it form other cotemporary civilisations. SALIENT FEATURES OF ISLAMIC CIVILISATION MAIN CHARACTERISTICS that distinguish Islamic civilisation from other civilisations and give it a unique position can be discerned as: • It is based on the Islamic faith. It is monotheistic, based on the belief in the oneness of the Almighty Allah, the Creator of this universe. It is characterised by submission to the will God and service to humankind. It is a socio-moral and metaphysical view of the world, which has indeed contributed immensely to the rise and richness of this civilisation. The author is a Ph. D. Research Scholar, Department of International Relations, University of Peshawar, N.W.F.P. Pakistan, the Additional Registrar of Qurtuba University and Editor of The Dialogue.

  • In and Around the Watermill
    In and around the watermill Our beautiful and historic watermill stands beside the River Rosaro in the small village of Posara. Peaceful and secluded, yet part of the village, the mill is just a mile or so from the walled medieval town of Fivizzano with its cafés, restaurants and shops. This is the heart of Lunigiana, in the North-west of Tuscany, a truly unspoilt part of Italy. Set in a gentle valley with mountain peaks in the background, the mill is a peaceful spot, surrounded by the National Park of the Tuscan-Emilian Appennines and The Regional Pak of the Apuan Alps, home of the marble mountains of Carrara. The Watermill is a complex of elegant and historic Tuscan buildings, around a sunny courtyard with an adjoining vine verandah, rose pergola and sun-filled walled garden. More gardens lead to walks along the river and the sun-dappled millstream. We have lovingly restored the historic buildings and created eight beautiful bedrooms with en suite bathrooms, plus two self-contained apartment suites, each with a double bedroom, bathroom and sitting room, ideal for couple or friends sharing. The bright and airy rooms are well decorated and tastefully furnished. Many contain original artworks and all enjoy lovely views of the river, the gardens or the mountains. Our graceful communal Sitting Room, with its gallery of paintings by our inspiring tutors, is ideal for post-prandial conversation and digestivi. Our courtyard dining room is the unique setting for leisurely breakfasts and mouth-watering evening meals. There is also a communal kitchen, with chilled water and facilities for personal tea-/coffee-making.

  • Palaeo-Environmental Condition Factor on the Diffusion of Ancient Water Technologies
    Gül Sürmelihindi Palaeo-Environmental Condition Factor on the Diffusion of Ancient Water Technologies Summary Thales of Miletus wisely declared that water is the vital element for life. Being the core sub- stance for human survival, the management of water has always been an important mat- ter. Early attempts to improve water-lifting devices for agricultural endeavors have been detected in Hellenistic Alexandria. However, aside from the limitations of the different de- vices, variations in geology also limit the use of some of these machines in specific areas. Some of these devices were used daily, whereas others remained impractical or were of mi- nor importance due to their complicated nature, and some were even forgotten until they were later rediscovered. Water also became a basic power source, providing energy, e.g. for cutting stone or milling grain, and such applications constituted the first attempts at Roman industrialization. Keywords: ancient water technologies; Hellenistic science; diffusion; geology; geography; Roman; aqueduct Bereits Thales von Milet erklärte Wasser zum wichtigsten Element allen Lebens. Entspre- chend kam dem Management dieser Ressource schon immer große Bedeutung zu. Erste Versuche, Wasser-Hebesysteme in der Landwirtschaft einzusetzen, lassen sich im Hellenis- tischen Alexandria nachweisen. Die Nutzbarkeit solcher Hebesysteme war eingeschränkt einerseits durch ihre individuelle Konstruktion, andererseits durch die Geologie vor Ort. Während dabei einige dieser Wasser-Hebesysteme täglichen Einsatz fanden, blieben andere ungenutzt oder gerieten auf Grund ihrer geringen Bedeutung oder ihrer Komplexität bis zu ihrer Wiederentdeckung in Vergessenheit. Wasser wurde damals auch als Energiequelle eingesetzt, wie zum Beispiel beim Schneiden von Steinen oder beim Mahlen von Korn. Sol- che Anwendungen stellen gleichsam den Anfang der antiken römischen Industrialisierung dar.

  • Water Wheels (Edited from Wikipedia)
    Water Wheels (Edited from Wikipedia) SUMMARY A water wheel is a hydropower system; a machine for extracting power from the flow of water. Water wheels and hydropower were widely used in the Middle Ages, powering most industry in Europe, along with the windmill. The most common use of the water wheel was to mill (or grind) flour in gristmills, but other uses included foundry work and machining, and pounding linen for use in paper. A water wheel consists of a large wooden or metal wheel, with a number of blades or buckets arranged on the outside rim forming the driving surface. Most commonly, the wheel is mounted vertically on a horizontal axle, but the tub or Norse wheel is mounted horizontally on a vertical shaft. Vertical wheels can transmit power either through the axle or via a ring gear and typically drive belts or gears; horizontal wheels usually directly drive their load. A channel created for the water to follow after leaving the wheel is commonly referred to as a "tailrace." HISTORY The technology of the water wheel had long been known, but it was not put into widespread use until the Middle Ages when an massive shortage of labor made machines such as the water wheel cost effective. However, the water wheels in ancient Rome and ancient China found many practical uses in powering mills for pounding grain and other substances. The Romans used both fixed and floating water wheels and introduced water power to other countries of the Roman Empire. The Romans were known to use waterwheels extensively in mining projects, with enormous Roman-era waterwheels found in places like modern-day Spain.

  • Micro-Hydroelectric Power and the Historic Environment
    Micro-Hydroelectric Power and the Historic Environment On 1st April 2015 the Historic Buildings and Monuments Commission for England changed its common name from English Heritage to Historic England. We are now re-branding all our documents. Although this document refers to English Heritage, it is still the Commission's current advice and guidance and will in due course be re-branded as Historic England. Please see our website for up to date contact information, and further advice. We welcome feedback to help improve this document, which will be periodically revised. Please email comments to [email protected] We are the government's expert advisory service for England's historic environment. We give constructive advice to local authorities, owners and the public. We champion historic places helping people to understand, value and care for them, now and for the future. HistoricEngland.org.uk/advice Micro-Hydroelectric Power and the Historic Environment PLANNING AND HISTORIC BUILDING LEGISLATION Installing a renewable power generation scheme can be both financially and environmentally rewarding. It is important to ensure that the historic significance of any feature that may be affected by the scheme is fully understood before physical work commences. In deciding how best to incorporate a low-carbon or renewable technology, the principle of minimum intervention and reversibility should be adopted whenever and wherever possible. English Heritage is the government’s adviser on the historic environment. Central to our role is the advice we give to local planning authorities and government departments on development proposals affecting listed and traditional buildings, conservation sites and areas, terrestrial and underwater archaeological sites, designed landscapes and historical aspects of the landscape as a whole.
