In this paper, we study the phonon thermal properties of a ladder nanostructure in harmonic approximation. We present a model consisting of two infinite chains with different masses. Then, we investigate the effect of different masses on the phonon spectrum. Moreover, as a specific case, in the absence of the second neighbor interaction, we calculate the phonon density of states/modes. Finally...
Case Description- A 2-yr-old intact male donkey (Equus asinus) was presented to Hospital of Veterinary Medicine, Mansoura University with subcutaneous masses under the tail. Clinical Findings- Physical examination revealed the presence of 2 separate 5x10 and 5x8-cm-diameter, round and firm subcutaneous masses. Treatment and Outcome<...
In a previous communicat ion (1) we presented da ta indicat ing tha t cardiac lesions, closely resembling those characteris t ic of rheumatic fever in man, had been induced in a small propor t ion of rabbi ts t ha t had undergone mult iple , successive skin infections with group A streptococci of several serological types. How the hypothesis leading to those experiments evolved is described els...
The quark and charged lepton masses and the angles and phase of the CKM mixing matrix are nicely reproduced in a model which assumes O(3) ⊗ O(3) flavour symmetry broken by the v.e.v.’s of fields in its bi-fundamental representation. The relations among the quark mass eigenvalues, mu/mc ≈ mc/mt ≈ m2d/m2s ≈ m2s/m2b ≈ Λ2GUT/M2 Pl, follow from the broken flavour symmetry. Large tanβ is required whi...
objective: to evaluate the adnexal masses with conventional gray scale and color doppler flow imaging and to assess their diagnostic reliability to differentiate benign and malignant adnexal masses. materials and methods: we evaluated 30 patients with adnexal mass. morphological characterization of the mass was done using sassone score. color doppler parameters noted down in each patient and ca...
Background Ultrasound is the first line modality in evaluation of pelvic masses in female patients. It is helpful in detection of masses and also in determining origin of them. Tissue characterization is possible with gray scale but Doppler study is quite necessary and considers as complimentary method. Most of the time, it should be performed in vaginal US exam. Existence of vascularity and al...
Background: Ovarian masses requiring surgical intervention are uncommon in the pediatric population. The aim of this study was to report results of a multicentric Tunisian study concerning the clinical practice and the management of pediatric ovarian masses and to identify the factors that are associated with ovarian preservation. Materials and Methods: Between January 2000 and December 2015...
In an attempt to determine the diagnostic value of FNA biopsy of head and neck masses, we reviewed FNAs performed on target lesions of the head and neck in1 59 patients who subsequently underwent surgery in Khalili hospital dur-. ing a 55 month period. Results ofFNAs were compared with postsurgical histologic diagnoses. These 159 cases were broken down into four categories: thyroid masses ...
a seven year-old boy with several painless masses on the ribs and shoulder was referred to our hospital. the masses were so prominent that they prevented the child’s sleep. since the patient had been ridiculed by his friends due to the rib prominences, he had refused to attend school. after clinical and radiological evaluations, the masses were diagnosed as hereditary multiple exostoses of the ...
abstract striped rice stem borer, chilo suppressalis walker (lepidoptera: pyralidae) is one of the important pests in rice fields of mazandaran. therefore, almost the farmers of northern iran apply several pesticides in nurseries for the pest control; while it is causes environmental risks and damages to human. in this research two different items including, 1- study of egg masses density in nu...
