Fibula Praeneste The Praeneste fibula has been the center of controversy amongst scholars since it’s initial presentation of discovery on January 7, 1887. There have been debates over the authenticity of the inscription ranging from the unique language and grammatical features to undetermined discovery site. The artifact has been estimated to origin from around the 7th century B.C., but there are scholars who argue the artifact is a forgery dating from the 19th century. The inscription uses lettering

it's detected early, so when in doubt, check it out. If a doctor suspects that a person has cancer, he or she will order various tests. These might include blood tests, (in which doctors scrutinise blood cells under a microscope to look for abnormalities), X-rays, or an MRI, (a scanning technique that can be used to detect tumours). Doctors also often use a biopsy to diagnose cancer. In this procedure, a doctor removes a small tissue sample to examine it for cancer cells. CANCER TREATMENT Most cancers

Microscopic organisms found in ocean cores can be used as a proxy for climate conditions in the passed. For example it is possible to determine whether it was relatively warm or cold based on the coiling direction of Neogloboquadrina pachyderma foraminifera. Right coiling (dextral) N. pachyderma indicates warmer conditions and left coiling (sinistral) indicates cooler conditions (Brunner 1994). It can also be assumed that if there is a high abundance and diversity of organism that conditions at the

by a 37 °C and 40% RH for 3 days. The biomaterials were then rehydrated in 20 mM HEPES for 24 hours. 6.2.2. Second Harmonic Generation Microscopy To observe fibrogenesis of AMC vitrigels, two-photon microscopy was performed using a Zeiss LSM-710 microscope (Carl Zeiss, Jena, Germany. Illumination was performed at a wavelength of 790 nm. Collagen fibrils were detected by its second-harmonic generation (SHG) signal below 480 nm. Images were recorded as z-stacks overarching the whole membrane with 1

distribution chart of zinc powder was obtained using Atomic force microscopy (AFM) SPM-AA3000 (Angestrom Advanced Inc., USA) in contact mode. The AFM images were recorded over a scan area (2 µm x 2 µm). The SEM micrographs were obtained using scanning electron microscope (FEI Company –Holland). The apparent density (da) of zinc powder was measured by the standard pycnometric method, and calculated based on the following formula: [24] d_a=(d_w (w_3-w_1))/((w_2-w_1 )-(w_4-w_3 )

60°. The magnetic hysteresis loops of 10 h milled powders and those of calcined at 1100 ͦ C were measured by a vibrating sample magnetometer 113 (VSM) (Lake Shore 7410, USA). The average particle size was obtained from the field emission scanning electron microscope (FESEM). X-ray photoemission spectroscopy (XPS) test was performed by a Thermo ESCALAB 250 with Al Kα radiation (hν=1486.6

In the current global economy, companies continuously search to improve efficiency, reduce overhead, and maintain positive financial growth. This search has led companies to look beyond their traditional market horizons for expansion opportunities. For many companies this includes establishing a strategic foothold in the international markets. Along with the challenges presented by ordinary program expansion are the security concerns posed by access to foreign markets and network as well as cultural

B.1. English Abstract According to the World Health Organization, cancer is a leading cause of death worldwide, and has the most devastating economic impact of any cause of death in the world. One of the leading causes of cancer-related mortality is gastric cancer, and that is due to the low rate of its diagnosis in its’ early stages as unfortunately, even the methods available for early detection of gastric cancer such as tumor biomarkers, are not very sensitive or efficient. Therefore, this proposal

material. The performance (pseducapacitive behavior) of the transition metal oxide electrodes are, mainly determined by the electrochemical activity and kinetic feature. They produced by fast faradaic reaction associated with the extraction of ions and electrons [2]. The spinel metal oxides assembled

Since the invention of implants, titanium has been the best material of choice due to its unique biocompatibility and the titanium dioxide (TiO2) corrosion resistance - compared to other metals which release ions into the adjacent tissue and cause inflammatory process. The important role in the biomaterial surface preparation has been a major study area for many scientists to enhance the surface properties for better dental and orthopedic implant osseointegration. The very last step of surface modification
