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

Informetrics on M. N. Srinivas
No full textM. N. Srinivas, the well known sociologist is widely recognised as architect of modern Indian sociology and social anthropology. His publications have been analysed by year, domain, authorship pattern, channels of communication used. Keywords, etc. The results indicate that the papers published by him are of a nature that qualify him to be a 'role model' for the younger generations to emulate.
By the end of 1995, Srinivas had to his credit 144 papers which, included 33 broad papers in sociology and anthropology; 18 papers in social change; 28 papers in village studies; 12 papers on religion; 17 papers on caste and 36 papers of general popular interest. The periods 1958-61 and 1974-77, when Srinivas was 38-41 and 58-61 years old. were his most productive periods with highest publication activity
The long-wavelength view of GG Tau A: rocks in the ring world
No full textWe present the first detection of GG Tau A at centimetre wavelengths, made with the Arcminute Microkelvin Imager Large Array at a frequency of 16 GHz (λ = 1.8 cm). The source is detected at >6 σrms with an integrated flux density of S16GHz = 249 ± 45 µJy. We use these new centimetre-wave data, in conjunction with additional measurements compiled from the literature, to investigate the long-wavelength tail of the dust emission from this unusual protoplanetary system. We use an MCMC-based method to determine maximum likelihood parameters for a simple parametric spectral model and consider the opacity and mass of the dust contributing to the microwave emission. We derive a dust mass of Md ~ 0.1 Msun, constrain the dimensions of the emitting region and find that the opacity index at λ > 7 mm is less than unity, implying a contribution to the dust population from grains exceeding ~4 cm in size. We suggest that this indicates coagulation within the GG Tau A system has proceeded to the point where dust grains have grown to the size of small rocks with dimensions of a few centimetres. Considering the relatively young age of the GG Tau association in combination with the low derived disc mass, we suggest that this system may provide a useful test case for rapid core accretion planet formation models
