Earth Resistivity Tomography (ERT) investigation of Machaerus Fortress
No full textNew campaigns to survey the structures and materials, explorative studies and specialist localized surveys permit constant up-dates to knowledge of the fortress and the village in a broader cognitive framework concerning both historical aspects and this directly tied to the material consistency of the architectural remains. The aforementioned initiative also offers new occasion for assessing the future potential of the research and the risk levels for the structures. The results of Machaerus may constitute a useful cognitive element for comparison with other sites/monuments in Jordan and offer occasions for reflection about the current management policy of the historical and artistic patrimony.
In this work we present and discuss the results obtained following the application of the Electrical Resistivity Tomography (ERT) in the subsurface investigation of a portion of the Qala’at al Mishaqa
Structurally Integrated Slotless PM Brushless Motor with Spiral Wound Laminations for Marine Thrusters
No full textRim driven thrusters with structurally integrated brushless PM motors are now an established technology with an increasing range of applications. In these thrusters, the stator of the motor is housed within the thruster duct, and the rotor forms a ring around the tips of the propeller. Such high pole number motors tend to be very thin radialy, have very small length to diameter ratios, and have relatively large airgaps to accommodate corrosion protection layers on the surfaces of the rotor and stator. The relatively large diameter stator laminations of such machines tend therefore to have very thin back of core and narrow teeth, which make them expensive and difficult to manufacture. This paper proposes an alternative potentially lower cost motor topology featuring a slotless stator whose laminations are manufactured from a single strip of steel that is edge wound into a spiral (like a “slinky” and then fitted over the windings that are preformed on the outside surface of a non-conducting former. The former is also part of the sealed housing that protects the stator from corrosion in seawater. The paper discusses the design optimisation of such a motor using analytical and finite element analysis (FEA), describes a demonstrator motor and reports experimental and FEA results

Al-Sharif Al-Radi: His Life and Poetry
No full textThe aim of this work is to study al-Sharif al-Radl, his life and poetry. The first part deals with the poet’s environment and life; the second with his poetry. Chapter I deals with the political conditions under which the poet lived. The purpose of the second chapter is to portray Al-Radl's social environment and its reflection in contemporary poetry. The third chapter describes the literary environment of Al-Radl's age at some length. The fourth chapter aims to study Al-Radl's life in detail. The factors which influenced his outlook and personality are discussed. An attempt is made to discern how far these factors affected his poetry. The second part of this work deals with Al-Radl's poetry itself. In Chapter V historical observations are made on Al-Radl's Diwan o in both manuscript and published forms. Chapter VI deals with his panegyrics. General remarks are made on eulogy in Arabic poetry. The content, form and development of Al-Radl's panegyrical odes are analysed. His Ikhwaniyyat receive special attention. Chapter VII deals with Al-Radl's self-praise its content and form. An endeavour is made to explore the Utopian world which the poet tried to portray, Al-Radl's elegies (Ch. VIII). their content, form and characteristics are reviewed. In addition, his dirges on women receive attention. Shi ism in Al-Radl’s poetry is discussed in Chapter IX, Al-Radl’s love-poetry (Ch. X) is discussed. His Hijaziyyat receive particular attention. It is claimed that Al-Radl’s produced in his Hijaaiyyat a poetical amalgam which contains some aspects of ‘Udhrite and ’Umarite poetry. Chapter II deals with Al-Radl's poetical technique. His theories of poetical composition and his comments on other poets are examined. A comparison is made between Al-Radl and other poets both previous and contemporary. Special attention is paid to al-Mutanabbi's influence. In Chapter XII there is a broad re-assessment of Al-Radl’s place in the history of Arabic poetry

Variations in surface ozone at Nainital : a high-altitude site in the central Himalayas
No full textSurface ozone measurements have been made for the first time at Nainital (29.37 degrees N, 79.45 degrees E, 1958 m amsl), a high-altitude site in the central Himalayas, between October 2006 and December 2008. Diurnal variations in ozone do not show the daytime photochemical build-up typical of urban or rural sites. The seasonal variation shows a distinct ozone maximum in late spring (May; 67.2 +/- 14.2 ppbv) with values sometimes exceeding 100 ppbv and a minimum in the summer/monsoon season (August; 24.9 +/- 8.4 ppbv). Springtime ozone values in the central Himalayas are significantly higher than those at another high-altitude site (Mt. Abu) in the western part of India. Seasonal variations in ozone and the processes responsible for the springtime peak are studied using meteorological parameters, insolation, spatial and temporal classifications of air mass trajectories, fire counts, and simulations with a chemical transport model. Net ozone production over the Northern Indian Subcontinent in regionally polluted air masses is estimated to be 3.2 ppbv/day in spring but no clear build-up is seen at other times of year. Annual average ozone values in regionally polluted air masses (47.1 +/- 16.7 ppbv) and on high insolation days (46.8 +/- 17.3 ppbv) are similar. Background ozone levels are estimated to be 30-35 ppbv. Regional pollution is shown to have maximum contribution (16.5 ppbv) to ozone levels during May-June and is about 7 ppbv on an annual basis, while the contribution of long-range transport is greatest during January-March (8-11 ppbv). The modeled stratospheric ozone contribution is 2-16 ppbv. Both the trajectory analysis and the model suggest that the stratospheric contribution is 4-6 ppbv greater than the contribution from regional pollution. Differences in the seasonal variation of ozone over high-altitude sites in the central Himalayas (Nainital) and western India (Mt. Abu) suggest diverse regional emission sources in India and highlight the large spatial and temporal variability in ozone over the Indian region
