Abundant steeply-dipping thick coal seams (SDTCS) have been found in Xinjiang, China, and they are mined largely by the horizontal section top-coal caving (HSTCC) method. The hanging wall of the HSTCC face is nearly vertical and does not fracture easily after the underlying coal is extracted. As a result, stress tends to concentrate in the hanging wall of the lower-section working face (LSWF) a...

the emarat pb-zn mine is located at about 80 km south of the city of arak , iran. i the present mine-scale litho geochemical survey 56 hanging wall samples and 37 footwall samples were taken form exploratory tunnels, drillholes and open pit all samples were taken in the range of 0-40 m from pb-zn veins. the relationship between three variables including concentration of zn in wallwork, distance...

[1] An extensive deep-tow magnetic survey of the TAG ridge segment on the MidAtlantic Ridge reveals new information about the relationship between the magnetic anomaly field and the TAG hydrothermal deposits. Results show the strongest magnetization is located over the neovolcanic axis and asymmetrically toward the western side of the central Brunhes anomaly. A well-defined linear magnetization...

The synchronization of two pendulum clocks hanging from a wall was first observed by Huygens during the XVII century. This type of synchronization is observed in other areas, and is fundamentally different from the problem of two clocks hanging from a moveable base. We present a model explaining the phase opposition synchronization of two pendulum clocks in those conditions. The predicted behav...

(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...

An integrated petrologic, thermochronologic, and numerical modeling study constrains the thermal evolution of the Lesser Himalayan Sequence in the Kumaun and Garwhal regions of India. South of the Tons thrust, peak metamorphic temperatures do not exceed 330 °C. On the northern side, a transition toward higher temperatures adjacent to the Main Central thrust hanging wall is documented. In the im...

vaginal leiomyomas are uncommon benign tumour with variable clinical presentation. these tumours arise most commonly from anterior vaginal wall. we report a case of 50-year old postmenopausal woman who presented with urinary retention, profuse vaginal bleeding and mass protruding into vagina. local examination revealed a pedunculated mass attached to the posterior vaginal wall with vascular sta...
