Hardback. Condition: New. 1st. This book provides a timely, comprehensive and evidence-based review of minimally invasive surgery of the cervical, thoracic and lumbar spine.Minimally invasive techniques are now aided by more advanced endoscopic instruments, video, and computerised navigation systems broadening the range of surgi…cal procedures that can be carried out with similar efficacy as traditional open spinal surgeries, without the significant burden on the patient recovery and rehabilitation.This book thoroughly reviews the preclinical and clinical data on minimally invasive spinal surgery and describes and illustrates the current effective techniques.An authoritative, international team of contributors add their clinical experience and expertise to provide a clear, authoritative and practical guide.The book is organised in four sections covering cervical, thoracic and lumbar spine regions with a final section on the latest advances in technologies and the cost-effectiveness of current treatments.

Add to basketNo Binding. Condition: Good. 1st Edition. A set of four adjoining US Army K462 Series colour printed maps, including the very significant Western Persian Gulf sheet. Each approx 85x100cm, adapted from Aramco-USGS originals. All stated first editions, first printings dated Feb 1964 (Edition 1-AMS). Good overall. Neatly folded wit…h pinholes to some corners and edges, some wear along folds, occasional small areas of staining, and the original USGS map numbers in ms to the edges. The originals were prepared as part of the groundbreaking USGS-Aramco mapping exercise for the Saudi Government during 1956-63. One of its main products was a series of Geographic maps divided into 21 Quadrangles on a 1/500K scale, numbered I-200B to I-220B. These along with their geological equivalents were designed to support exploration and exploitation of petroleum, minerals, and groundwater. Evidenced by this set, the Geographic series also proved highly valuable to the US Army's Corps of Engineers, which was supporting Saudi Arabia through a massive long-term construction and infrastructure development programme. The AMS additions include a Universal Transverse Mercator grid, and marginal data revised to 1963. The maps are labelled in English and Arabic, including a Glossary, sources of base compilation, and Index Map. Details include international boundaries (where they exist), settlements of various sizes (including ruins, date gardens, and cultivated areas); transport (rail and stations, types of road and camel tracks, landing fields and airports). Hydrogaphic features include wells, wadis etc. Hypsographic features include descriptions of different types of sand terrain. Miscellaneous features include oil and gas installations. The sheets adjoin in 2 rows of 2, between them covering the area bounded by Safaniyah (NW), Gezdan (NE), Uruq (SE), and Al Arawik (SW), taking in all of Qatar and Bahrain, parts of Saudi Arabia and Iran, and parts of what would become the UAE. SHEETS: (1) NG 39-W: Western Persian Gulf, Saudi Arabia, Bahrain, Qatar. Copied from Map I-208B originally prepared in 1958 by a joint Aramco-USGS team including Max Steineke, TF Harriss, KR Parsons, and EL Berg. This covers the Gulf coast from Safaniyah to the western half of Qatar, including all of Bahrain, and the key Aramco locations including Al Khobar, Dhahran, Dammam, Jubail, Ras Tanura, Abqaiq, etc. Installations include the Trans-Arabian Pipeline with Tapline Road and the Al Qatif-Al Qaysumah Pipeline that feeds into it, with the Saudi Government Railroad to the lower edge. Among significant local sites are the port of Uqair, Hofuf Oasis, and the Darb Al Uqayr connecting them, and other ancient camel trails including Darb Huwwijan, Darb Mazalij, Darb Mikhyat, and Darb Az Zuayyini. Installations and settlements are also shown in Bahrain and Qatar, with partially defined maritime boundaries. // (2) NG 39-E: Central Persian Gulf, Arabia, Iran. Copied from Map I-209B originally prepared in 1959 by Aramco's Richard Bramkamp and Leon Ramirez. Extending eastward from NG 39-W, this covers the Arabian coast from the eastern half of Qatar to Ar Ruways, and the Iranian coast from the islands of Jabrin to Jazireh-ye Qeys. // (3) NF 39-W: Northwestern Rub al Khali, Saudi Arabia. Copied from Map I-213B originally prepared in 1959 by Bramkamp and Ramirez. This is the continuation inland of NG 39-W. // (4) NF 39-E: Northeastern Rub al Khali, Saudi Arabia. Copied from Map I-214B originally prepared in 1959 by Bramkamp and Ramirez. Extending westward from NF 39-W and southwards from NG 39-E.

Add to basket2 sheets (A, combined map of geography and geology; and B, geography only) in full colour, both covering the same section the Arabian Peninsula. Ca. 103 x 103 and 83 x 100 cm, folded. In original printed envelope. English and Arabic. Scale 1:500,000; relief shown by hachures and spot heights. The only two sheets of the groundbre…aking series covering today's UAE - the remaining parts of the Emirates were skipped in the survey prepared by the U.S. Geological Survey and Aramco and were therefore never published. The first to produce a full series of geological and geographical maps of the Kingdom of Saudi Arabia, the venture was instrumental in establishing the country as a major global force in the production of natural resources and must count as "a unique experiment in geological cooperation among several governments, petroleum companies, and individuals" (Seager/Johnston). - The area here covered is the eastern portion of Qatar and the westernmost area of Abu Dhabi, including the island of Sir Bani Yas and the adjoining border territory of Saudi Arabia. Indeed, this is the only map in the series to show any portion of today's United Arab Emirates: the land to the eastward was still beyond the focus of oil exploration in the mid-1950s and was omitted from the mapping project. - The importance of the present map within the series is underscored by the fact that its joint authors, R. A. Bramkamp and L. F. Ramirez, were Aramco's foremost geologists. Together with Glen F. Brown, a veteran of the industry who also had been in the region since the 1940s and who would oversee the venture, Bramkamp had in February 1955 planned the entire programme, laying down everything from the scales of maps, the areas of responsibility, and types of terrain representation to the bilingual names. As Aramco's chief geologist, Bramkamp was responsible for the compilation of the areas within Arabia where the sediments crop out. This responsibility fell to Ramirez following Bramkamp's early death in September 1958. - The surveyors divided the Peninsula into 21 quadrangular sections (numbered I-200 through I-220), each to cover an area 3 degrees of longitude and 4 degrees of latitude. All maps were produced on a 1:500,000 scale and issued in two series: a combined map of geography and geology (marked by the appendix 'A') and a map of geography only ('B'). "High altitude photography [.] was [.] completed in 1959 [.] This controlled photography resulted in highly accurate geographic maps at the publication scale which then served as a base for the geologic overlay. The topography of the sedimentary areas was depicted by hachuring and that of the shield region by shaded relief utilizing the airbrush technique. The first geographic quadrangle was published in July 1956 and the last in September 1962 [.] The first of the geologic map series was published in July 1956 and the final sheet in early 1964" (Seager/J.). - Although it was the search for oil, gas and minerals that "was ultimately to drive geological survey work across the region [.], in its early years it was the need for water that was the catalyst for Saudi Arabia's resource exploration. In 1944 King 'Abd al-'Aziz approached the United States for a technical expert who could assist with the identification and plotting of the kingdom's natural resources, particularly its groundwater reserves [.] By 1954 the Saudi Ministry of Finance, USGS and Aramco were working together to produce the first full series of geographic and geologic maps of the country. The first of their type in the Peninsula, these were published [.] in both Arabic and English versions, and the information they contained formed the basis of subsequent Saudi national development plans" (Parry). The project was considered highly important by Ibn Saud, and its aims encompassed all aspects of cartography. It was to enable not only the search for natural resources but also aid in advances for agriculture, civil and military engineering a.
