Patients suffering from bone defects are often treated with autologous bone transplants, but this therapy can cause many complications. New approaches are therefore needed to improve treatment for bone defects, and stem cell therapy presents an exciting alternative approach. Although extensive evidence from basic studies using stem cells has been reported, few clinical applications using stem c...

Basal crevasses may play an important precursory role in determining both the location and propagation of rifts and iceberg dimensions. For example, icebergs calved recently from Thwaites Glacier, Antarctica, have the same width as surface undulations, strengthening the connection between basal crevasses, rifting and calving. We explore a novel method for estimating the heights of basal crevass...

In the family of III-nitride compounds, BxGa1 xN is particularly attractive because it can be lattice matched to AlN or SiC substrates. In this work we studied in detail the relationship between morphology, composition, and boron surface segregation in BxGa1 xN layers grown on GaN template substrates by MOVPE. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) observations rev...

Introduction. Male infertility is one of the main causes forced childlessness couples around world. Currently, a limited number drugs for treatment male are available on market. Biologically active supplements (dietary supplements) containing L-carnitine often used in complex therapy. The results determining therapeutic activity new drug, peptide obtained from cattle testes (PP-R-001) and compa...

Reklamcılık alanının teorisi ve uygulamaları hızla gelişmektedir. Her hızlı gelişim veya değişim sürecinde yaşandığı gibi reklam uygulamalarında da sıklıkla etik mevzuat açısından birçok ihlalin ortaya çıktığı görülmektedir. Reklamın denetimi ile ilgili hükümleri, reklamcılıktaki değişimlerle bağlantılıdır. Reklam etiğine ilişkin değerlendirmeler ise daha çok toplumların kültürleriyle ilintilid...

Terrestrial Gamma ray Flashes (TGFs) are short flashes of high energy photons, produced by thunderstorms. When interacting with the atmosphere, they produce relativistic electrons and positrons, a part gets bounded to geomagnetic field lines travels large distances in space. This phenomenon is called Electron Beam (TEB). The Atmosphere-Space Interactions Monitor (ASIM) mounted on-board Internat...

Methods: Nine healthy volunteers participated in this beforeafter, pilot clinical trial. Human allogeneic collagen (Collagel, Kimia Teb Rahavard Co., Tehran, Iran) was injected in both nasolabial folds of the volunteers. Skin hydration was measured using the Corneometer® 580 device (CK GmbH, Cologne, Germany). Ultrasonic dermal changes were measured using an ultrasonography device (22 MHz, TPM,...

The value and merit of triethylborane (TEB)-based ate complexes for the synthesis various oxygenated polymers have been recently illustrated through successful examples homopolymerization epoxides their copolymerization with CO2, CS2, COS, anhydrides, isocyanates, etc. To further expand scope TEB-based initiating systems to a broader family polymers, they were used in this study anionically pol...

The Visible Infrared Imaging Radiometer Suite (VIIRS) on board the National Oceanic and Atmospheric Administration-20 (NOAA-20) Suomi Polar-orbiting Partnership Program (S-NPP) satellites were launched in late 2017 2011, respectively. This paper presents a recent update VIIRS thermal emissive bands (TEB) on-orbit calibration algorithm inter-compares long-term instrument TEB sensor data records ...
