This shows Onychonycteris finneyi, a bat fossil. The image shows its wing digits widely spread out with small claws on tip of each finger. It also shows the long tail found in earlier bat fossils (Moskowitz, 2008). Molecular Mechanisms The origins of bats wing muscles, molecular and cellular mechanisms are unknown but this research shows that the wing muscles of bats come from “a multiple myogenic source of different embryonic origins” (Tokita, Abe, && Suzuki, 2012). The results conclude that…

ABSTRACT Elaeis guineensis is a species of palm generally called African oil palm, and it can reach the height of 20 m or more at maturity. The oil palm is major importance in Africa as a multi-purpose tree where it supplies medicines, foods and many other products to the local population. Elaeis guineensis is rapidly becoming one of the world's most planted plants, being grown especially for its oil-bearing seeds and fruits. Usually 23 kg is the average weight of each bunch but a bunch may up…

Introduction The incidence of acne vulgaris throughout the world has previously been reported as 9.4%,1 while other estimates in the literature indicate an upper limit for the rates for adults as 50% and 80% for adolescents.2 Outbreaks can eventually lead to scarring or skin discoloration3 and severe forms include high levels of general inflammation as well as the presence of large nodules. However, the physical effects are of less general significance than secondary psychological reactions,…

plane was confirmed by X-ray diffraction studies. The crystallite size of SnS2 thin films was found to increase with the increase in precursor solution volume up to 20 ml and then it decreased at the precursor solution volume of 25 ml. The scanning electron microscope established the presence of platelet-like shaped grains. The composition elements of tin and sulfur were found to be present and found to be closely nearly to the stoichiometric ratio by EDAX analysis. The thickness of these films…

Friction is a crucial phenomenon in metal cutting which is very complex to model. It has a significant effect on the amount of power required for removing a given volume of metal, surface quality of the finished product, and the extent of tool wear. However, many studies assume no friction in the metal cutting process due to lack of experimental techniques to directly measure the coefficient of friction. Sticking and sliding regions are the two contact regions along the tool-chip interface. A…

In coronal suture lower coronal suture closure started early compared to upper coronal suture. Within the coronal suture lower suture appears to fuse much faster than upper coronal suture.(113) Verma et al(13) said that in Female subjects (33%) in the Coronal Suture - the lower ½ part of this suture get fused at the age of 42-44 yrs and is followed by upper ½ part, which is found fused at the age of 56 yrs Author Year Race Method Time of closure of Coronal Suture Krogman (10) 1962 USA Gross…

CHAPTER I INTRODUCTION 1.1 BACKGROUND STUDY Wastewater in the textile , plastic, paper and cosmetics industry is a major threat to the environment. The volume of wastewater produced starts from different processes throughout from the pretreatments to the final treatment. The contents found in the wastewater are complex, having inorganic and organic compound chemicals in it and aquatic lives are at risk. Some of these wastes have even caused mutation in genetic coding of the marine…

Tribological behavior of double-glow plasma Zirconium-Yttrium alloying on γ-TiAl Cong Huang, Pingze Zhang*, Dongbo Wei, Xiangfei Wei, Xiaohu Chen and Feng Ding (College of Materials Science and Technology, Nanjing University of Aeronautics and Astronautics, Nanjing 211100, China) * Corresponding author: pzzhang_nuaa@126.com Abstract: A Zr-Y alloyed layer was prepared onto the surface of γ-TiAl using double-glow plasma surface alloying technique (DG technique). The results showed that the Zr-Y…

Chapter 1 Introduction Waste generated from food industries is a source of an untapped energy which is mostly dumped inland fills whereby it releases greenhouse gases into the atmosphere. It is very difficult to treat and recycle food waste due to its composition. Food industry produces large volumes of wastes, both solids and liquid, resulting from the production, preparation and consumption of food. These wastes lead to increasing waste disposal and can pose severe pollution problems and…
