TL;DR: The proventricular surface epithelial cells and smooth muscle cells of the proventriculus and gizzard showed a moderate to strong reaction for adenosine triphosphatase and the proprial gland cells revealed histochemical distribution and activity of various enzymes and lipids similar to that of the submucosal gland cells.
Abstract: The proventricular surface epithelial cells were positive for both acid and neutral mucins and stained intensive for acid phosphatase and adenosine triphosphatase. The proprial gland cells revealed histochemical distribution and activity of various enzymes and lipids similar to that of the submucosal gland cells. However, the ductular cells of the submucosal glands showed comparatively stronger reaction for acid phosphatase, alkaline phosphatase, adenosine triphosphatase, lipase and carbonic anhydrase except for succinic dehydrogenase. In gizzard, the koilin was positive for both acid and neutral mucin. The epithelial cells of the proprial glands stained strongly for adenosine triphosphatase and moderately for acid and alkaline phosphatases. However, their response for succinic dehydrogenase and lipase was weak. The smooth muscle cells of the proventriculus and gizzard showed a moderate to strong reaction for adenosine triphosphatase.

TL;DR: From neonatal to adult age group animals, the dermal thickness was found to be increased in all the regions in the present study.
Abstract: Micrometrical studies on the skin of Madras red sheep was conducted in neonatal, young and adult age groups. The skin was the thickest on the neck dorsal region and thinnest on the thorax ventral region, in all the age groups studied. The epidermis on the dorsal regions was found to be slightly thicker than the lateral and ventral regions of neck, thorax and loin. From neonatal to adult age group animals, the dermal thickness was found to be increased in all the regions in the present study. The diameter of primary hair follicle was more than the secondary hair follicle and also the location of primary hair follicle was deeper to secondary hair follicle.

TL;DR: A comprehensive review of the latest developments of the various types of perovskite piezoelectric ceramic systems is presented in this article, with special attention given to three promising families of lead-free perovsite ferroelectrics: the barium titanate, alkaline niobate and bismuth pervskites.
Abstract: High strain piezoelectric ceramics are the state-of-the-art materials for high precision, positioning devices. A comprehensive review of the latest developments of the various types of perovskite piezoelectric ceramic systems is presented herein, with special attention given to three promising families of lead-free perovskite ferroelectrics: the barium titanate, alkaline niobate and bismuth perovskites. Included in this review are details of phase transition behavior, strain enhancement approaches, material reliabilities as well as the status of some promising applications. This current review describes both compositional and structural engineering approaches that are intended to achieve enhanced strain properties in perovskite piezoelectric ceramics. The factors that affect the strain behavior of high-strain perovskite piezoelectric ceramics are addressed. The reliability characteristics of these high-strain ferroelectrics as well as the recent approaches to the long-term electrical, thermal and time-stability enhancement are summarized. Several promising applications of high-strain perovskite materials are introduced, which take advantages of their characteristics; examples include high-energy storage, pyroelectric and electro-caloric effect and luminescent properties.
