Basic microwave properties of magnetic photonic (MPC) and degenerate band edge (DBE) crystals are investigated mathematically and experimentally. Two dimensional and three dimensional models are considered demonstrating the very high sensitivity and field growth associated with these crystals. A major part of the paper deals with the development of realistic anisotropic periodic structures usin...

The Federal Highway Administration (FHWA) mandates the use of affirmative action for minorityand women-owned firms by states in awarding federally funded road construction projects. In this paper, I document the variation of affirmative action across states over the history of the FHWA program, and I provide evidence regarding the effectiveness of affirmative action at increasing purchases from...

Starch accumulation and the seven metabolic enzyme activities in sorghum grains with different starch contents were investigated under field conditions Shenyang Agricultural University. The results indicated that Tieza17 (high content variety) Liaoza11 (low could be fitted logistic equation. of sucrose synthase (SS), soluble (SSS) uridine diphosphate glucose pyrophosphorylase (UGPase) similar t...

نقش صلاحیت فردی و رضایت شغلی ممیزان مالیاتی در ارتقاء سطح قدرت "مالیات‌ستانی" توسط سازمان امور کشور: بررسی محدودیت (فشار) زمان

Double-balloon endoscopy (DBE) has enabled precise diagnosis and endoscopic intervention deep within the small bowel. In this study, we determine the factor related to the risk of endoscopic and clinical recurrences in the diagnosis of postoperative lesions including anastomosis for the patients with Crohn's disease. Forty-eight patients (40 men and 8 women) had undergone small bowel resection ...

The phase stability of DE and DBE blends at different component concentrations, as well as the effects of using DBE blends including ethanol of various proportions on a CI engine performance are experimentally investigated. The engine was operated with DBE blends having 5, 10, 15 and 20% ethanol with fixed 10% biodiesel on a volume basis, to solve the phase separation problem, as well as on die...

An ecosystem is a self-sustaining, self-organizing, collaborative and evolving environment. Ecosystem exists in nature as a biological ecosystem of living and non living species and their physical environment. This paper carries a thorough comparative analysis and analogy between different types of ecosystems and further suggests a sustainable, stable and formidable framework of Digital Busines...

Background and Aim Overt obscure gastrointestinal bleeding (OOGIB) is defined as continued with unknown source despite esophagogastroduodenoscopy (EGD) colonoscopy evaluation. Small bowel evaluation through video capsule endoscopy (VCE) or double balloon enteroscopy (DBE) often warranted. We studied the timing of DBE in hospitalized OOGIB patients regarding diagnostic yield, therapeutic GI rebl...

AIM To assess the feasibility and utility of double balloon enteroscopy (DBE) in the management of small bowel diseases in children. METHODS Fourteen patients (10 males) with a median age of 12.9 years (range 8.1-16.7) underwent DBE; 5 for Peutz-Jeghers syndrome (PJ syndrome), 2 for chronic abdominal pain, 4 for obscure gastrointestinal (GI) bleeding, 2 with angiomatous malformations (1 blue ...
