CSE blew the lid on smog and smogmakers in 1996 in its book Slow murder: The deadly story of vehicular pollution in India. The study found that the problem of vehicular pollution in India was the result of a combination of outdated engine technology, poor fuel quality, defective transportation planning and bad maintenance of vehicles on road. CSE exposed that the government was indulging in the...

برای دستیابی به مزیت رقابتی در شرایط عدم‌­اطمینان که آن تغییر ضروری است، یکی از چالش‌های بزرگ سازمان‌ها کاهش ریسک طریق ایجاد زنجیره‌های تأمین تاب‌آور است. تاب‌آوری زنجیره ‌تأمین توانایی مقابله با اختلال اشاره دارد یک رویداد غیرقابل‌پیش‌بینی بوده و دارای منابع داخلی خارجی مختلفی ازجمله بلایای طبیعی ریسک‌های عملیاتی پژوهش حاضر شبیه‌سازی توسط نرم‌افزار ارنا زنجیره‌ سنگ ساختمانی «کارخانه سنگبری آسم...

The sorption of VOCs by different building materials can significantly affect VOC concentrations in indoor environments. In this paper, a new model has been developed for simulating VOC sorption and desorption rates of homogeneous building materials with constant diffusion coefficients and material-air partition coefficients. The model analytically solves the VOC sorption rate at the material-a...

OBJECTIVES To assess the clinical performance of the Ambu Aura-i (Aura-i) in children. AIM To compare the Aura-i with the air-Q intubating laryngeal airway (air-Q) for the purposes of fiberoptic-guided tracheal intubation. BACKGROUND The Aura-i is a new supraglottic airway designed for tracheal intubation. MATERIALS/METHODS One hundred twenty children, ages 1 month to 6 years, were random...

Bound states in the continuum (BIC)-based all-silicon metasurfaces have attracted widespread attention recent years because of their high quality (Q) factors terahertz (THz) frequencies. Here, we propose and experimentally demonstrate an BIC metasurface consisting air-hole array on a Si substrate. BICs originated from low-order TE TM guided mode resonances (GMRs) induced by (1,0) (1,1) Rayleigh...

We propose a hybrid optical nanocavity consisting of photonic crystals coupled to a metal surface with a nanoscale air gap between. The hybridization of photonic crystal modes and surface plasmons across the gap forms hybrid cavity modes, which are highly confined in the low-loss air gap region. Deep subwavelength mode volume and high quality factor are demonstrated at telecommunication wavelen...

we conducted this study to determine the risk of transmission of q fever to health care workers (hcws) during perioperative exposure to coxiella burnetii -infected thoracic endovascular aneurysm stent graft. pre-operative and 6-week post-operative phase i and ii igg q fever antibody titers were determined in 14 staff members of an operation room. the room had a negative pressure and all the mem...
