abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
backgrounds: bleomycin (blm) has been labeled with radioisotopes and widely used in therapy and diagnosis. in this study blm was labeled with [62zn] zinc chloride for oncologic pet studies. materials and methods: the complex was obtained at the ph=2 in normal saline at 90 ° c in 60 min. radio-tlc showed an overall radiochemical yield of 95-97% (radiochemical purity > 97%). stability of complex ...
abstract background and aim: secondary caries are a common challenge for dentists. many researchers have evaluated the accuracy of digital radiographic systems in the detection of secondary caries and have reported controversial results. therefore, the aim of this in vivo study was to determine the diagnostic accuracy of digital radiography in the detection of secondary caries in anterior teeth...

let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
cutaneous leishmaniasis is endemic in 88 different countries. there are an estimated 1.5 million new cases each year, with over 90% occurring in afghanistan, algeria, iran, iraq, saudi arabia, syria (old world) and in brazil and peru (new world). miltefosine is effective in vitro and in vivo against leishmania species and it was demonstrated efficacy in animals via the oral route. this study is...
Aneuploidy, an imbalanced chromosome number, is associated with both cancer and developmental disorders such as Down syndrome (DS). To determine how aneuploidy affects cellular and organismal physiology, we have developed a system to evaluate aneuploid cell fitness in vivo. By transplanting hematopoietic stem cells (HSCs) into recipient mice after ablation of recipient hematopoiesis by lethal i...
OBJECTIVE To investigate the toxicity of methanol extract of various parts (Root, Stem, Leaf, Flower and Fruit) of Lantana camara (L. Camara) in Artemia salina. METHODS The methanol extracts of L. camara were tested for in vivo brine shrimp lethality assay. RESULTS All the tested extract exhibited very low toxicity on brine shrimp larva. The results showed that the root extract was the most...
