the present paper is concerned with  the investigation of disturbances in a homogeneous  transversely isotropic thermoelastic rotating  medium with two temperatures, in the presence of the combined effects of   hall currents and magnetic field due to thermomechanical sources. the formulation is applied to the thermoelasticity theories developed by green-naghdi theories of type-ii and type-iii. ...

An earthquake of M, = 5.3 occurred at 32°58.7'N, 117°51.5'W southwest of Oceanside in San Diego County at 13:47 13 July 1986 (UT). This main shock was followed by an extensive aftershock sequence, with 55 events of ML > 3.0 during July 1986. The epicenters of the main shock and aftershocks are located at the northern end of the San Diego Trough-Bahia Soledad fault zone (SDT-BS) where it changes...

The region of Stuttgart, located in the south-western part of Germany, favors warm and humid climate accompanied by a low wind speed. Stuttgart lies in a basin-like sink and is surrounded by hills, a fact, which enforces the specific formation of these thermal and air quality conditions. The Urban Heat Island (UHI) of Stuttgart and its spatial distribution were assessed using thermal indices Ph...

a microporous bisphenol a diglycidyl ether (dgeba) epoxified-polyethersulfone (pes) blend membrane (epes membrane) was prepared through dry-wet phase inversion. this study attempts to correlate the changes in membrane physical and chemical properties when the epes membranes were exposed to different durations of dry-phase inversion, towards the separation efficiency of carcinogen chromium (vi)....

a method is described by which it is possible to determine the high barrier to ring inversion and hindered rotation by neat racemization of optically active compounds when the racemization is caused by ring inversion or hindered rotation. the method is based preparation of sufficiently pure enantiomers, mainly by chromatography on swollen microcrystalline triacetylcellulose (tac). by this techn...

uterine inversion is shortly described as the indentation and depression of the fundic area extending downwards up to the different levels of the birth canal till vaginal opening. clinical diagnosis of uterine inversion is difficult due to its non-specific symptoms and physical examination. ultrasonography is the most practical modality for radiological evaluation, but it is inadequate to deter...

The secondary lining failure of deep buried soft rock tunnel often occurs, which is obviously related to the time factor. formation mechanism this phenomenon studied in paper. Therefore, combination situ stress measurement and neural network inversion used analyze distribution characteristics stress. At same time, creep surrounding are tested laboratory, key parameters obtained. Combined with r...

It has long been known that the urban surface energy balance is different to that of a rural surface, and that heating of the urban surface after sunset gives rise to the Urban Heat Island (UHI). Less well known is how flow and turbulence structure above the urban surface are changed during different phases of the urban boundary layer (UBL). This paper presents new observations above both an ur...

Appreciable injection-induced seismicity has been occurring in northcentral Oklahoma since 2009. To better understand these earthquakes, we have compiled new information on the state of stress in the state to compare it with both mapped faults and faults inferred from earthquake epicenters and focal plane mechanisms. Seventy-five new in situ stress orientations are available from wellbores thro...
