Abstract. A number of general shear experiments on Black Hills Quartzite (BHQ) in the dislocation creep regime, 5 of which have been analyzed previously using the CIP method (Heilbronner & Tullis, 2002 and 2006), are (re-)examined using the higher spatial and orientational resolution of EBSD. Segmentations based on c-axis orientation and on full crystallographic orientations are compared. Texture domains of preferred c-axis orientation are extracted and analyzed separately. Subdomains are recognized and their shape and size is related the kinematic framework and the original grains in the BHQ. Grain size analysis using a segmentation based on c-axis orientations is carried out for all, high and low strain samples of all regimes, and for a number of texture domains. The results are compared to the recrystallized quartz piezometer of Stipp & Tullis (2003), returning consistently higher values for stress or grain size. Possible causes for the discrepancy are texture dependence, grain scale strain, and dependence on the kinematic framework (in axial versus general shear experiments).

Microelectrodes are being developed in order to record action biopotentials of insects. Silicon was conventionally used as the electrode material and microelectrodes were fabricated by anisotropic etching and reactive ion etching. Because electrode microprobe shape and size were very difficult to control, we propose a novel pin-shaped multichannel microelectrode. Epoxy-based UV photoresist must be used as the electrode material to facilitate the control of the microelectrode shape and size. Analysis of the electrical properties of this electrode showed that it has properties excellent enough to record insect biopotentials.

A study was carried out in three administrative units (tehsils) of Poonch district of Azad Jammu and Kasmir (AJK) state to record the presence of true morels belonging to genus Morchella of class Ascomycetes. A periodic random survey was carried out during the year 2015-16. Distribution of four species of morels Morchella esculenta (40%), M. elata (30%), M. deliciosa (20%) and M. semilibera (10%) was recorded during survey period from February 15 to March 30. During rest of months of survey period no morel was observed in the same locations. The temperature during collection ranged between 3-7 °C. Morels were found growing under plant canopies, tree shades and on disturbed grass lands. To isolate, morels were dug out with the help of shovel and spade. Detailed macro and microscopic features such as stipe, pileus, spore shape and size were recorded. The minimum pileus diameter measured was about 1.0-2.5 cm in M. semilibera, while the maximum measurement of pileus diameter was 7.0-7.5 cm in M. elata. The minimum stipe length was about 1.5-5.0 cm in M. deliciosa, while the maximum measurement was observed 7.0-10.0 cm in M. semilibera. In addition, spore print (yellow, pale and black) was observed, while the maximum spore size was found in case of M. semilibera. The findings of this study showed the presence of four different species of morels in Poonch district of Azad Jammu and Kashmir.
